Thread Programming in C++/CLR
|
<p>I am really struggling with Thread programming in Visual C++/CLR. I have searched a lot and found lots of material on the internet including the official resources however i am still confused. There are very few resources for C++/CLR. Most of them are for C# or old style C++. I try to run this simple code. I choose a new project of type clr console applicatioN and place the following code there but i am getting errors which i am not understading. </p>
<pre><code>// thread_clr.cpp : main project file.
#include "stdafx.h"
using namespace System;
using namespace System;
using namespace System::Threading;
class MessagePrinter;
// class ThreadTester demonstrates basic threading concepts
class ThreadTester
{
static int Main()
{
// Create and name each thread. Use MessagePrinter's
// Print method as argument to ThreadStart delegate.
MessagePrinter printer1 = gcnew MessagePrinter();
Thread thread1 = gcnew Thread ( gcnew ThreadStart( printer1.Print ) );
thread1.Name = "thread1";
MessagePrinter printer2 = gcnew MessagePrinter();
Thread thread2 = gcnew Thread ( gcnew ThreadStart( printer2.Print ) );
thread2.Name = "thread2";
MessagePrinter printer3 = gcnew MessagePrinter();
Thread thread3 = gcnew Thread ( gcnew ThreadStart( printer3.Print ) );
thread3.Name = "thread3";
Console.WriteLine( "Starting threads" );
// call each thread's Start method to place each
// thread in Started state
thread1.Start();
thread2.Start();
thread3.Start();
Console.WriteLine( "Threads started\n" );
} // end method Main
}; // end class ThreadTester
class MessagePrinter
{
private int sleepTime;
private static Random random = gcnew Random();
// constructor to initialize a MessagePrinter object
public MessagePrinter()
{
// pick random sleep time between 0 and 5 seconds
sleepTime = random.Next( 5001 );
}
//controls Thread that prints message
public void Print()
{
// obtain reference to currently executing thread
Thread current = Thread.CurrentThread;
// put thread to sleep for sleepTime amount of time
Console.WriteLine(current.Name + " going to sleep for " + sleepTime );
Thread.Sleep ( sleepTime );
// print thread name
Console.WriteLine( current.Name + " done sleeping" );
} // end method Print
} // end class MessagePrinter
</code></pre>
<p>Please help. Or better still please guide me to some tutorials or something to that affect. I understand SO is not a tutorial site and i am not asking one but i would appreciate if some one could atleast point out the resources for C++/CLR thread. C++/CLR Winform Threads. Would really appreciate it</p>
<p>Regards</p>

Java RMI cannot bind server
|
<p>I'm working on Java RMI application, and having problem binding a server to the registry. I'm working on eclipse using rmi plugin, and everything worked fine before I had to format my pc. Also, I'm sure the code is ok since it's the one given to me as a solution, so there must be something wrong with my configuration.
Here's the code:</p>
<pre><code>public static void main (String[] args){
try{
RMIChatServer myObject = new RMIChatServerImpl();
System.setSecurityManager(new RMISecurityManager());
Naming.rebind("Hello", myObject);
System.out.println("Remote object bound to registry");
}
catch( Exception e){
System.out.println("Failed to register object " + e);
e.printStackTrace();
System.exit(1);
}
}
</code></pre>
<p>Exceptions it gives:</p>

<p>I researched the problem and most say that it's because of codebase settings (I also use security policy), I have tried different settings, and currently using 'compute from classpath' option provided by rmi plugin, which worked before, but fails now :( Please advice!</p>

Why does my Android service get restarted when the process is killed, even though I used START_NOT_STICKY?
|
<p>My app uses a pattern where I start a service with <a href="http://developer.android.com/reference/android/content/Context.html#startService%28android.content.Intent%29" rel="noreferrer">Context#startService()</a> as well as bind to it with <a href="http://developer.android.com/reference/android/content/Context.html#bindService%28android.content.Intent,%20android.content.ServiceConnection,%20int%29" rel="noreferrer">Context#bindService()</a>. This is so that I can control the lifetime of the service independently from whether any clients are currently bound to it. However, I noticed recently that whenever my app is killed by the system, it soon restarts any services that were running. At this point the service will never be told to stop, and this is causing battery drain whenever it happens. Here's a minimal example:</p>
<p>I found someone with a similar issue <a href="https://groups.google.com/forum/?fromgroups=#!topic/android-developers/x4pYZcXeKsw" rel="noreferrer">here</a>, but it wasn't ever diagnosed or solved.</p>
<p>Service:</p>
<pre><code>@Override
public void onCreate() {
Toast.makeText(this, "onCreate", Toast.LENGTH_LONG).show();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_NOT_STICKY;
}
@Override
public IBinder onBind(Intent intent) {
return new Binder();
}
</code></pre>
<p>Activity:</p>
<pre><code>@Override
protected void onStart() {
super.onStart();
Intent service = new Intent(this, BoundService.class);
startService(service);
bindService(service, mServiceConnection, 0);
}
@Override
protected void onStop() {
unbindService(mServiceConnection);
Toast.makeText(this, "unbindService", Toast.LENGTH_SHORT).show();
super.onStop();
}
</code></pre>
<p>To test it, I launched the app, which started the service and bound to it. Then I backed out of the app, which unbinds (but leaves the service running). Then I did</p>
<pre><code>$ adb shell am kill com.tavianator.servicerestart
</code></pre>
<p>and sure enough, 5 seconds later, the "onCreate" toast appears, indicating that the service started again. Logcat shows this:</p>
<pre><code>$ adb logcat | grep BoundService
W/ActivityManager( 306): Scheduling restart of crashed service com.tavianator.servicerestart/.BoundService in 5000ms
I/ActivityManager( 306): Start proc com.tavianator.servicerestart for service com.tavianator.servicerestart/.BoundService: pid=20900 uid=10096 gids={1028}
</code></pre>
<p>If I replace the startService() pattern with BIND_AUTO_CREATE, the problem doesn't occur (even if I crash the app while it's still bound to the service). It also works if I never bind to the service. But the combination of start, bind, and unbind seems to never let my service die.</p>
<p>Using dumpsys before killing the app shows this:</p>
<pre><code>$ adb shell dumpsys activity services com.tavianator.servicerestart
ACTIVITY MANAGER SERVICES (dumpsys activity services)
Active services:
* ServiceRecord{43099410 com.tavianator.servicerestart/.BoundService}

how to make junit test run methods in order
|
<p>guys! I have a new question for you. I'm adding some data to cache using different cache managers and I'm facing the problem with it. I'm doing it using junit and spring. When I run the test, the test methods are executed randomly, but I need them to be executed in order. How to do it?? Here is some code and a proving console output:</p>
<p>Service class:</p>
<pre><code>@Service("HelloCache")
public class CacheServiceImpl implements CacheInterface {
@Autowired
@Qualifier("memcachedClient")
private MemcachedClient mBean;
public void Add(String key, Object object) {
mBean.set(key, 12, object);
}
public void Get(String key) {
mBean.get(key);
}
public void Delete(String key) {
mBean.delete(key);
}
}
</code></pre>
<p>Here is the test: </p>
<pre><code>@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "file:src/main/java/spring.xml")
public class UsingMemcachedTest extends TestCase {
@Autowired
@Qualifier("HelloCache")
private CacheInterface emcached;
private byte[][] i = new byte[2500][3000];
private String key = "j";
@Test
public void testAddBulkObjects() {
System.out.println("");
System.out.println("This is async BULK adding test");
long time = System.currentTimeMillis();
for (int k=1; k<=1000; k++) {
emcached.Add(key+k, i);
}
long time2 = System.currentTimeMillis();
long timeE=time2-time;
System.out.println("Vremya add BULK objects: " + timeE);
System.out.println("");
}
@Test
public void testGetBulkObjects() {
System.out.println("");
System.out.println("This is getting BULK objects test");
long time = System.currentTimeMillis();
for (int k=1; k<=1000; k++) {
emcached.Get(key+k);
}
long time2 = System.currentTimeMillis();
long timeE=time2-time;
System.out.println("Vremya Get object: " + timeE);
System.out.println("");
}
@Test
public void testDeleteBulkObjects() {
System.out.println("");
System.out.println("This is deleting BULK objects test");
long time = System.currentTimeMillis();
for (int k=1; k<=1000; k++) {
emcached.Delete(key+k);
}
long time2 = System.currentTimeMillis();
long timeE=time2-time;
System.out.println("Vremya delete object: " + timeE);
System.out.println("");
}
</code></pre>
<p>And the output: </p>
<pre><code>This is deleting BULK objects test
Vremya delete object: 137
This is getting BULK objects test
Vremya Get object: 703
This is async BULK adding test
Vremya add BULK objects: 87681
</code></pre>

Using Unity3D's IPointerDownHandler approach, but with "the whole screen"
|
<p>In Unity say you need to detect finger touch (finger drawing) on something in the scene.</p>
<p>The only way to do this <strong>in modern Unity, is very simple</strong>:</p>
<hr>
<p><strong>Step 1</strong>. Put a collider on that object. ("The ground" or whatever it may be.) <sup>1</sup></p>
<p><strong>Step 2.</strong> On your camera, Inspector panel, click to add a Physics Raycaster (2D or 3D as relevant).</p>
<p><strong>Step 3.</strong> Simply use code as in Example A below.</p>
<p><em>(Tip - don't forget to ensure there's an EventSystem ... sometimes Unity adds one automatically, sometimes not!)</em></p>
<hr>
<p>Fantastic, couldn't be easier. Unity finally handles un/propagation correctly through the UI layer. Works uniformly and flawlessly on desktop, devices, Editor, etc etc. Hooray Unity.</p>
<p>All good. But what if you want to draw just <strong>"on the screen"</strong>?</p>
<p>So you are wanting, quite simply, swipes/touches/drawing from the user "on the screen". (Example, simply for operating an orbit camera, say.) So just as in any ordinary 3D game where the camera runs around and moves.</p>
<p>You don't want the position of the finger on <strong>some object</strong> in world space, you simply want abstract "finger motions" (i.e. position on the glass).</p>
<p>What collider do you then use? Can you do it with no collider? It seems fatuous to add a collider just for that reason.</p>
<p><strong>What we do is this</strong>:</p>
<p>I just make a flat collider of some sort, and actually attach it <strong>under the camera</strong>. So it simply sits in the camera frustum and completely covers the screen.</p>
<p><a href="https://i.stack.imgur.com/wQOv4.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wQOv4.png" alt="enter image description here"></a></p>
<p>(For the code, there is then no need to use ScreenToWorldPoint, so just use code as in Example B - extremely simple, works perfectly.)</p>
<p>My question, it seems a bit odd to have to use the "under-camera colldier" I describe, just to get touches on the glass.</p>
<p>What's the deal here?</p>
<p>(Note - please don't answer involving Unity's ancient "Touches" system, which is unusable today for real projects, you can't ignore .UI using the legacy approach.)</p>
<hr>
<p>Code sample A - drawing on a scene object. Use ScreenToWorldPoint.</p>
<pre><code> using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;
public class FingerMove:MonoBehaviour, IPointerDownHandler, IDragHandler, IPointerUpHandler
{
public void OnPointerDown (PointerEventData data)
{
Debug.Log("FINGER DOWN");
prevPointWorldSpace =
theCam.ScreenToWorldPoint( data.position );
}
public void OnDrag (PointerEventData data)
{
thisPointWorldSpace =
theCam.ScreenToWorldPoint( data.position );
realWorldTravel =
thisPointWorldSpace - prevPointWorldSpace;
_processRealWorldtravel();
prevPointWorldSpace = thisPointWorldSpace;
}
public void OnPointerUp (PointerEventData data)
{
Debug.Log("clear finger...");
}
</code></pre>
<p>Code sample B ... you only care about what the user does on the glass screen of the device. Even easier here:</p>
<pre><code> using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;
public class FingerMove:MonoBehaviour, IPointerDownHandler, IDragHandler, IPointerUpHandler
{
private Vector2 prevPoint;
private Vector2 newPoint;
private Vector2 screenTravel;
public void OnPointerDown (PointerEventData data)
{
Debug.Log("FINGER DOWN");
prevPoint = data.position;
}
public void OnDrag (PointerEventData data)
{
newPoint = data.position;
screenTravel = newPoint - prevPoint;
prevPoint = newPoint;
_processSwipe();
}
public void OnPointerUp (PointerEventData data)
{
Debug.Log("FINEGR UP...");
}
private void _processSwipe()
{
// your code here
Debug.Log("screenTravel left-right.. " + screenTravel.x.ToString("f2"));
}
}
</code></pre>
<hr>
<p><sup>1</sup> If you're just new to Unity: at that step very likely, make it a layer called say "Draw"; in physics settings make "Draw" interact with nothing; in step two with the Raycaster just set the layer to "Draw".</p>

How do I show a label beyond a certain zoom level in Leaflet?
|
<p>I'm pretty new to the Leaflet library, and to JavaScript in general, and I'm stuck trying to figure out how to show/hide a leaflet Label based on the zoom level (and the markers are in a 'cluster' layer). </p>
<p>The markers are all loaded via AJAX callback and then I bind the popup and label using the <code>onEachFeature</code>, then I add the layer of geoJson markers to the map. </p>
<p>I'd like to only show the labels when zoomed in to some level, but I haven't had any luck. I also tried adding the <code>leaflet.zoomcss.js</code> but I guess I'm not using that correctly. </p>
<p><strong>Sample</strong></p>
<pre><code>var officesLayerGroup = L.markerClusterGroup();
var currentMakers;
function DiaplyLocalOffices(jqOffices) {
currentMakers = new L.geoJson(jqOffices, {
style: function (feature) {
var c = feature.properties.markercolor;
if (feature.properties.OfficeID == 0) {
c = 'yellow';
}
return { color: c };
},
pointToLayer: function (feature, latlng) {
return new L.CircleMarker(latlng, { radius: 7, fillOpacity: 0.5 });
},
onEachFeature: bindOfficePopup
});
officesLayerGroup.addLayer(currentMakers);
map.addLayer(officesLayerGroup);
}
function bindOfficePopup(feature, layer) {
// This function adds the popup based on the information in the 'layer' or marker
// Keep track of the layer(marker)
feature.layer = layer;
var props = feature.properties;
if (props) {
var desc = '<span id="feature-popup">';
//.. a bunch of other html added here!
var warn = props.Warning ? props.Warning : null;
if (warn !== null) {
desc += '<font size="4" color="red"><strong><em>' + warn + '</em></strong></font></br>';
}
desc += '</span>';
layer.bindPopup(desc);
layer.bindLabel('Hi Label!', { noHide: true, className: 'my-css-styled-labels'});
}
}
</code></pre>
<p>I've also tried adding it like this but that didn't work either:</p>
<pre><code> layer.on({
zoomend: showLabel(e)
});
</code></pre>
<p>and then a quickie function:</p>
<pre><code>function showLabel(e) {
z = map.getZoom();
if (z > 6) {
layer.bindLabel("HIYA", { noHide: true, className: 'my-css-styled-labels' });
}
}
</code></pre>
<p>But no luck, even when adding the library and CSS styles for <code>leaflet.zoomcss.js</code></p>
<p>Sorry for being lengthy, but any help would be really appreciated! </p>

Spring MVC @RequestMapping not working
|
<p>I have a strange scenario in which my controller is not invoked unless I map the dispatcher servlet to /* in web.xml. I have defined a controller with a RequestMapping:</p>
<pre><code>@Controller
public class UserController {
@RequestMapping(value = "/rest/users", method = RequestMethod.GET)
public ModelAndView getUsers(HttpServletRequest request) throws RestException {
...
}
}
</code></pre>
<p>And an application context:</p>
<pre><code><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
<context:component-scan base-package="com.test.rest.controller" />
</code></pre>
<p>Finally this is mapped in web.xml:</p>
<pre><code><servlet>
<servlet-name>rest-servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/restContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>rest-servlet</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</code></pre>
<p>This works as expected i.e. I can make requests to /rest/users. However if I change the web.xml mapping to:</p>
<pre><code><servlet-mapping>
<servlet-name>rest-servlet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</code></pre>
<p>I get an MVC error:</p>
<blockquote>
<p>WARN servlet.PageNotFound: No mapping found for HTTP request with URI
[/rest/users] in DispatcherServlet with name 'rest-servlet'.</p>
</blockquote>
<p>It seems really strange because the error indicates that the request is being mapped to the dispatcher-servlet, yet the only thing that has changed is the servlet mapping. </p>
<p>Has anyone else encountered this?</p>

MVC 3 client side validation, model binding decimal value and culture (different decimal separator)
|
<p>I am trying to have my client side validation (model binding) to support different cultures, and I found an interesting blog on the subject on which I am trying to implement.</p>
<p><a href="http://haacked.com/archive/2011/03/19/fixing-binding-to-decimals.aspx" rel="noreferrer">http://haacked.com/archive/2011/03/19/fixing-binding-to-decimals.aspx</a></p>
<p>Poco</p>
<pre><code> public class Jogador
{
public int ID { get; set; }
public string Name { get; set; }
public decimal Salary { get; set; }
}
</code></pre>
<p>I've got my custom DecimalModelBinder class</p>
<pre><code> public class DecimalModelBinder : IModelBinder
{
public object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
ValueProviderResult valueResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
ModelState modelState = new ModelState {Value = valueResult};
object actualValue = null;
try
{
actualValue = Convert.ToDecimal(valueResult.AttemptedValue, CultureInfo.CurrentCulture);
}
catch (FormatException e)
{
modelState.Errors.Add(e);
}
bindingContext.ModelState.Add(bindingContext.ModelName, modelState);
return actualValue;
}
}
</code></pre>
<p>My web.config:</p>
<p>
</p>
<p>
</p>
<p>
</p>
<pre><code><compilation debug="true" targetFramework="4.0">

</code></pre>
<p></p>
<p>
</p>
<p>
</p>
<p>Global.asax are altered to use my custom ModelBinder on decimal and decimal? values</p>
<pre><code>protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder());
ModelBinders.Binders.Add(typeof(decimal?), new DecimalModelBinder());
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}
</code></pre>
<p>Still the client-side validation fails on decimal entered in my view with a "," as a decimal separator. It does not handle both "," and ".". The js validation does not seem to take my custom binding in consideration</p>
<p>Reading the blog article over and over again, I just can't seem to figure out what I am missing.</p>
<p>Here is the view:</p>
<pre><code>@model MVC_Empty.Web.Models.Jogador
@{
ViewBag.Title = "Create";
}
<h2>Create</h2>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>
@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
<fieldset>
<legend>Jogador</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Salary)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Salary)
@Html.ValidationMessageFor(model => model.Salary)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
</code></pre>
<p>Server side validation seems fine, but how to handle the client-side validation in order to send a POST when clicking the submit button.</p>
<p>The javascript validation does not handle the comma.<img src="https://i.stack.imgur.com/wVpyh.png" alt="enter image description here">

C free() invalid next size (normal)
|
<p>I'm fairly new to C and I can't seem to figure out what seems to be a pretty simple pointer problem. My program adds line numbers to a file. It reads in the file line by line and then adds a line number to the beginning of each line. It works fine on each file individually as you can see below:</p>
<pre><code>soccer@soccer-Dell-DV051:~/code C$ ./a.out test.c
soccer@soccer-Dell-DV051:~/code C$ ./a.out miscellaneousHeader.h
soccer@soccer-Dell-DV051:~/code C$ ./a.out test.c miscellaneousHeader.h
*** Error in `./a.out': free(): invalid next size (normal): 0x08648170 ***
Segmentation fault (core dumped)
soccer@soccer-Dell-DV051:~/code C$
</code></pre>
<p>but when I run them together I get the above error. The following code is my program.</p>
<p>Compiler.c:</p>
<pre><code>#include <stdio.h>
#include "lineNumAdderHeader.h"
#include "miscellaneousHeader.h"
int main(int argc, char *argv[]){
if (argc < 2)
fatal("in main(). Invalid number of arguments");
int i = 1;
while (i < argc){
lineNumAdder(argv[i]);
i++;
}
}
</code></pre>
<p>I have narrowed the problem to the <code>lineNumPtr</code>. The error occurs when <code>lineNumPtr</code> is freed after the second file. If <code>lineNumPtr</code> is not freed, which I know is bad programming, the program works just fine.</p>

Yii2 Form in Modal Window
|
<p>I would like to understand the basics of how to work with form from Modal window in Yii2? This is my current understanding and I will be grateful if someone can explain me what I missed.
So, I have a ListView with records. Each record contains a button. The button opens a Modal with a Form inside:</p>
<pre><code>echo Html::a('<span class="glyphicon glyphicon-bell" aria-hidden="true"></span>', ['#'],[
'id' => $model->id,
'class' => 'linkbutton',
'data-toggle'=>'modal',
'data-tooltip'=>'true',
'data-target'=>'#submit_vote'.$model->id,
'title'=> 'Assign'
]);
Modal::begin([
'size' => 'modal-lg',
'options' => [
'id' => 'submit_vote'.$model->id,
],
'header' => '<h2>Create Vote</h2>',
'footer' => 'Footer'
]);
ActiveForm::begin([
'action' => 'vote/vote',
'method' => 'post',
'id' => 'form'.$model->id
]);
echo Html::input(
'type: text',
'search',
'',
[
'placeholder' => 'Search...',
'class' => 'form-control'
]
);
echo Html::submitButton(
'<span class="glyphicon glyphicon-search"></span>',
[
'class' => 'btn btn-success',
]
);
ActiveForm::End();
Modal::end();
</code></pre>
<p>In Form 'action' I wrote vote/vote and method post. So I expect post data inside actionVote function of my VoteController.</p>
<pre><code>public function actionVote()
{
if (Yii::$app->request->post()) {
$id = Yii::$app->request->post('search');
Yii::$app->session->setFlash('error', $id);
return true;
}
}
</code></pre>
<p>For submitting I use an ajax:</p>
<pre><code>$('form').on('submit', function () {
alert($(this).attr('id')+$(this).attr('action')+$(this).serialize()); //just to see what data is coming to js
if($(this).attr('id') !== 'searchForm') { //some check
$.ajax({
url: $(this).attr('action'),
type: 'post',
data: $(this).serialize(),
success: function(){
$("#submit_vote15").modal('hide'); //hide popup
},
});
return false;
}
</code></pre>
<p>But after click on Submit form I see two alerts. Modal also not hidden. Flash message also is not showed.
What I am doing wrong? Can anyone clearly explain a step by step procedure of data flow? For now my understanding is:</p>
<ol>
<li>Open Modal;</li>
<li>Click Form Submit inside Modal;</li>
<li>Load data via ajax to controller action;</li>
<li>catch data from post and execute controller action code;
What I missed?</li>
</ol>

How to set timeout on event onChange

<p>I have a gallery that show images, and i have a search textbox
Im Trying to use Timeout on Input event to prevent the api call on every letter im typing :
I try to handle the event with doSearch function onChange: but now I cant write anything on the textbox and it cause many errors
Attached to this session the app and gallery components</p>

TableLayoutPanel rows & columns at runtime
|
<p>im trying to build a usercontrol which contains a tablelayoutpanel. in this panel i need to dynamically add 3 columns with each having different a width and 5 rows which all shell have the same height (20% of the tablelayoutpanel's height).</p>
<p>column1 should have an absolute width of 20,
column2 depending a width on its content (a textbox with .dock = fill)
column3 a width of 30.</p>
<p>my code:</p>
<pre><code>Private Sub BuildGUI()
If Rows > 0 Then
tlp.Controls.Clear()
tlp.ColumnStyles.Clear()
tlp.RowStyles.Clear()
If Style = Styles.Adding Then
tlp.ColumnStyles.Add(New ColumnStyle(SizeType.Absolute, 30))
tlp.ColumnStyles.Add(New ColumnStyle(SizeType.Autosize))

PHP 'Years' array
|
<p>I am trying to create an array for years which i will use in the DOB year piece of a form I am building. Currently, I know there are two ways to handle the issue but I don't really care for either:</p>
<h2>1) Range:</h2>
<p>I know I can create a year array using the following</p>
<pre><code><?php
$year = range(1910,date("Y"));
$_SESSION['years_arr'] = $year;
?>
</code></pre>
<p>the problem with Point 1 is two fold: a) my function call shows the first year as 'selected' instead of "Year" as I have as option="0", and b) I want the years reversed so 2010 is the first in the least and shown decreasing.</p>
<p>My function call is:</p>
<p><strong>PHP</strong></p>
<pre><code><?php
function showOptionsDrop($array, $active, $echo=true){
$string = '';
foreach($array as $k => $v){
$s = ($active == $k)? ' selected="selected"' : '';
$string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n";
}
if($echo) echo $string;
else return $string;
}
?>
</code></pre>
<p><strong>HTML</strong></p>
<pre><code><table>
<tr>
<td>State:</td>
<td><select name="F1State"><option value="0">Choose a year</option><?php showOptionsDrop($_SESSION['years_arr'], null, true); ?></select>
</td>
</tr>
</table>
</code></pre>
<hr>
<h1>2) Long Array</h1>
<p>I know i can physically create an array with years listed out but this takes up a lot of space and time if I ever want to go back and modify.</p>
<p>ex: <strong>PHP</strong></p>
<pre><code>$years = array('1900'=>"1900", '1901'=>"1901", '1902'=>"1902", '1903'=>"1903", '1904'=>"1904", '1905'=>"1905", '1906'=>"1906", '1907'=>"1907", '1908'=>"1908", '1909'=>"1909", '1910'=>"1910", '1911'=>"1911", '1912'=>"1912", '1913'=>"1913", '1914'=>"1914", '1915'=>"1915", '1916'=>"1916", '1917'=>"1917", '1918'=>"1918", '1919'=>"1919", '1920'=>"1920", '1921'=>"1921", '1922'=>"1922", '1923'=>"1923", '1924'=>"1924", '1925'=>"1925", '1926'=>"1926", '1927'=>"1927", '1928'=>"1928", '1929'=>"1929", '1930'=>"1930", '1931'=>"1931", '1932'=>"1932", '1933'=>"1933", '1934'=>"1934", '1935'=>"1935", '1936'=>"1936", '1937'=>"1937", '1938'=>"1938", '1939'=>"1939", '1940'=>"1940", '1941'=>"1941", '1942'=>"1942", '1943'=>"1943", '1944'=>"1944", '1945'=>"1945", '1946'=>"1946", '1947'=>"1947", '1948'=>"1948", '1949'=>"1949", '1950'=>"1950", '1951'=>"1951", '1952'=>"1952", '1953'=>"1953", '1954'=>"1954", '1955'=>"1955", '1956'=>"1956", '1957'=>"1957", '1958'=>"1958", '1959'=>"1959", '1960'=>"1960", '1961'=>"1961", '1962'=>"1962", '1963'=>"1963", '1964'=>"1964", '1965'=>"1965", '1966'=>"1966", '1967'=>"1967", '1968'=>"1968", '1969'=>"1969", '1970'=>"1970", '1971'=>"1971", '1972'=>"1972", '1973'=>"1973", '1974'=>"1974", '1975'=>"1975", '1976'=>"1976", '1977'=>"1977", '1978'=>"1978", '1979'=>"1979", '1980'=>"1980", '1981'=>"1981", '1982'=>"1982", '1983'=>"1983", '1984'=>"1984", '1985'=>"1985", '1986'=>"1986", '1987'=>"1987", '1988'=>"1988", '1989'=>"1989", '1990'=>"1990", '1991'=>"1991", '1992'=>"1992", '1993'=>"1993", '1994'=>"1994", '1995'=>"1995", '1996'=>"1996", '1997'=>"1997", '1998'=>"1998", '1999'=>"1999", '2000'=>"2000", '2001'=>"2001", '2002'=>"2002", '2003'=>"2003", '2004'=>"2004", '2005'=>"2005", '2006'=>"2006", '2007'=>"2007", '2008'=>"2008", '2009'=>"2009", '2010'=>"2010");

What happens when there's insufficient memory to throw an OutOfMemoryError?
|
<p>I am aware that every object requires heap memory and every primitive/reference on the stack requires stack memory.</p>
<p>When I attempt to create an object on the heap and there's insufficient memory to do so, the JVM creates an <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/OutOfMemoryError.html">java.lang.OutOfMemoryError</a> on the heap and throws it to me.</p>
<p>So implicitly, this means that there is some memory reserved by the JVM on startup.</p>
<p>What happens when this reserved memory is used up (it would definitely be used up, read discussion below) and the JVM does not have enough memory on the heap to create an instance of <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/OutOfMemoryError.html">java.lang.OutOfMemoryError</a>?</p>
<p>Does it just hang? Or would he throw me a <code>null</code> since there's no memory to <code>new</code> an instance of OOM ?</p>
<pre><code>try {
Object o = new Object();
// and operations which require memory (well.. that's like everything)
} catch (java.lang.OutOfMemoryError e) {
// JVM had insufficient memory to create an instance of java.lang.OutOfMemoryError to throw to us
// what next? hangs here, stuck forever?
// or would the machine decide to throw us a "null" ? (since it doesn't have memory to throw us anything more useful than a null)
e.printStackTrace(); // e.printStackTrace() requires memory too.. =X
}
</code></pre>
<p>==</p>
<p><strong>Why couldn't the JVM reserve sufficient memory?</strong></p>
<p>No matter how much memory is reserved, it is still possible for that memory to be used up if the JVM does not have a way to "reclaim" that memory:</p>
<pre><code>try {
Object o = new Object();
} catch (java.lang.OutOfMemoryError e) {
// JVM had 100 units of "spare memory". 1 is used to create this OOM.
try {
e.printStackTrace();
} catch (java.lang.OutOfMemoryError e2) {
// JVM had 99 units of "spare memory". 1 is used to create this OOM.
try {
e.printStackTrace();
} catch (java.lang.OutOfMemoryError e3) {
// JVM had 98 units of "spare memory". 1 is used to create this OOM.
try {
e.printStackTrace();
} catch (java.lang.OutOfMemoryError e4) {
// JVM had 97 units of "spare memory". 1 is used to create this OOM.
try {
e.printStackTrace();
} catch (java.lang.OutOfMemoryError e5) {
// JVM had 96 units of "spare memory". 1 is used to create this OOM.
try {
e.printStackTrace();
} catch (java.lang.OutOfMemoryError e6) {
// JVM had 95 units of "spare memory". 1 is used to create this OOM.
e.printStackTrace();
//........the JVM can't have infinite reserved memory, he's going to run out in the end
}
}
}
}
}
}
</code></pre>
<p>Or more concisely:</p>
<pre><code>private void OnOOM(java.lang.OutOfMemoryError e) {
try {
e.printStackTrace();
} catch (java.lang.OutOfMemoryError e2) {
OnOOM(e2);
}
}
</code></pre>

Django ERROR: Invalid HTTP_HOST header: u'/run/myprojectname/gunicorn.sock:'
|
<p><em>I know that there are a lot of questions like this on SO, but none of them appear to answer my particular issue.</em></p>
<p>I understand that Django's <code>ALLOWED_HOSTS</code> value is blocking any requests to port <code>80</code> at my IP that do not come with the appropriate <code>Host:</code> value, and that when a request comes in that doesn't have the right value, Django is dropping me an email. I also know about the <a href="https://stackoverflow.com/a/17477436/231670">slick Nginx hack</a> to make this problem go away, but I'm trying to understand the nature of one such request and determine whether this is a security issue I need to worry about.</p>
<p>Requests like these make sense:</p>
<pre><code>[Django] ERROR: Invalid HTTP_HOST header: '203.0.113.1'. You may need to add u'203.0.113.1' to ALLOWED_HOSTS.
</code></pre>
<p>But this one kind of freaks me out:</p>
<pre><code>[Django] ERROR: Invalid HTTP_HOST header: u'/run/my_project_name/gunicorn.sock:'.
</code></pre>
<p>Doesn't this mean that the requestor sent <code>Host: /run/my_project_name/gunicorn.sock</code> to the server? If so, how do they have the path name for my <code>.sock</code> file? Is my server somehow leaking this information?</p>
<p>Additionally, as I'm running Django 1.6.5, I don't understand why I'm receiving these emails at all, as <a href="https://code.djangoproject.com/ticket/19866" rel="noreferrer">this ticket</a> has been marked fixed for some time now.</p>
<p>Can someone shed some light on what I'm missing?</p>
<p>This is my <code>settings.LOGGING</code> variable:</p>
<pre><code>{
'disable_existing_loggers': False,
'filters': {
'require_debug_false': {'()': 'django.utils.log.RequireDebugFalse'}
},
'formatters': {

'verbose': {'format': '%(levelname)s %(asctime)s %(module)s %(process)d %(thread)d %(message)s'}
},
'handlers': {
'console': {
'class': 'logging.StreamHandler',
'formatter': 'verbose',
'level': 'DEBUG'
},
'mail_admins': {
'class': 'django.utils.log.AdminEmailHandler',
'filters': ['require_debug_false'],
'level': 'ERROR'
}
},
'loggers': {
'django.request': {
'handlers': ['mail_admins'],
'level': 'ERROR',
'propagate': True
},
'my_project_name': {
'handlers': ['console'],
'level': 'DEBUG'
}
},
'version': 1
}
</code></pre>
<p>And here's my nginx config:</p>
<pre><code>worker_processes 1;

location = /500.html {

}
}
}
</code></pre>
<p>Lastly, I found this in my nginx access log. It corresponds to the emails coming through that complain about /run/myprojectname/gunicorn.sock being an invalid HTTP_HOST header.*</p>
<p>This was all on one line of course:</p>
<pre><code>2014/09/05 20:38:56 [info] 12501#0: *513 epoll_wait() reported that client
prematurely closed connection, so upstream connection is closed too while sending

"HEAD / HTTP/1.0", upstream: "http://unix:/run/myprojectname/gunicorn.sock:/"
</code></pre>
<p>Obviously I still don't know what this means though :-(</p>
<ul>
<li><strong><em>Update #1</strong>: Added my <code>settings.LOGGING</code></em></li>
<li><strong><em>Update #2</strong>: Added my nginx config</em></li>

Change Images on Custom CheckBox in WPF
|
<p>All I have created the following custom <code>CheckBox</code> which uses images instead of a <code>CheckBox</code>. This works well however, I want to be able to change the images as required. Ideally I would like to use application resources <code>Properties.Resources.SomeImage16</code> (a .png file). The XAML is </p>
<pre><code><Style x:Key="styleCustomCheckBox"
TargetType="{x:Type CheckBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<StackPanel Orientation="Horizontal">
<Image x:Name="imageCheckBox"
Width="16"
Height="16"
Source="F:\Camus\ResourceStudio\Graphics\Images\UnPinned16.png"/>
<ContentPresenter VerticalAlignment="Center"/>
</StackPanel>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="False">
<Setter TargetName="imageCheckBox"
Property="Source"
Value="F:\Camus\ResourceStudio\Graphics\Images\Pinned16.png"/>
</Trigger>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="imageCheckBox"
Property="Source"
Value="F:\Camus\ResourceStudio\Graphics\Images\UnPinned16.png"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</code></pre>
<p>With implementation </p>
<pre><code><ListBox SelectionMode="Single" >
<StackPanel Orientation="Horizontal">
<CheckBox Style="{StaticResource styleCustomCheckBox}"
HorizontalAlignment="Left"
VerticalAlignment="Center"
Margin="4,0,4,0"/>
<TextBlock VerticalAlignment="Top"
Text="SomeRecentDocument.resx"/>
</StackPanel>
</ListBox>
</code></pre>
<p><strong>How can I change the images used for the custom <code>CheckBox</code> (i.e. change the pinned/un-pinned to tick/cross etc.) without having to create a new style/template?</strong></p>
<p>Thanks for your time.</p>

fixed page, content scrolling behind header
|
<p>I am working on a website. I have most of the page fixed, except I want the table in the middle to scroll with the main scrollbar. Then I have an image in the background that I want to partially show through. I have it mostly working. The only part I cannot figure out is how to get the table content to go behind or even stop when it gets to the header. I will include a fiddle so you can see what I am talking about.

Undefined method `instance' for Capistrano::Configuration:Class
|
<p>I am trying to get Capistrano up and running for the first time in a rails app. I have a linux server running Ubuntu 12.04, nginx, unicorn and rails, however, I seem to be running into a few issues. I am also using Capistrano 3.0.0, rails 3.2.14, bundler 1.4.0 & ruby 1.9.3p448 using RVM. </p>
<p>I only have a production stage set up and at this point in time and I'm only concerned with Capistrano communicating with my server and pushing my code from github ( No migrations and bundling etc just yet).</p>
<p>When I try the command <code>cap production deploy:check</code> or <code>cap production deploy:setup</code> ( which seems to be deprecated?) with the setup below, I get the following error msg:</p>
<p>I'm not really sure where to start on this error, and google doesn't suggest much. I have tried adding the <code>rvm-capistrano</code> gem but to no avail. How can I amend my code to address this error?</p>

pg_upgrade on Windows cannot write to log file pg_upgrade_internal.log
|
<p>I'm trying to run pg_upgrade on Windows 2008R2, but I'm getting the error:</p>
<blockquote>
<p>cannot write to log file pg_upgrade_internal.log Failure, exiting</p>
</blockquote>
<p>I saw a similar question for Linux at <a href="https://stackoverflow.com/questions/23216734/cannot-write-to-log-file-pg-upgrade-internal-log-when-upgrading-from-postgresq">23216734</a> which explains that the issue is with permissions, but it doesn't help with Windows as I do not have a user named <code>postgres</code></p>
<p>Same goes for the <a href="http://www.postgresql.org/docs/current/static/pgupgrade.html" rel="noreferrer">pg_upgrade docs</a>, which mention a <code>postgres</code> user:</p>
<blockquote>
<p>RUNAS /USER:postgres "CMD.EXE"</p>
</blockquote>
<p>But again, I do not have such a user, and am trying to run this command as Administrator so I don't understand why I would have no permission. I even tried to do </p>
<pre><code>RUNAS /USER:Administrator "CMD.EXE"
</code></pre>
<p>And run pg_upgrade in the new command prompt, but am getting the same error.</p>
<p>Also, I am not sure which directory needs permissions? Where is the process trying to write <code>pg_upgrade_internal.log</code> to?</p>
<hr>
<p>More details:</p>
<p>The command I'm running is:</p>
<pre class="lang-none prettyprint-override"><code>C:\Apps\postgresql\pgsql-9.5.0\bin>pg_upgrade.exe --old-datadir=E:\PGSQL_data --new-datadir=E:\PGSQLData\pgsql-9.5 --old-bindir=C:\Apps\postgresql\pgsql-9.4.5.3\bin --new-bindir=C:\Apps\postgresql\pgsql-9.5.0\bin
</code></pre>
<p>From the same command prompt that gives the error I ran the following commands and they all worked, creating an empty file in the respective directories, so write permissions to the directories that are passed to pg_upgrade are allowed:</p>
<pre><code>C:\Apps\postgresql\pgsql-9.5.0\bin>type nul > E:\PGSQL_data\_test_write_permission.txt
C:\Apps\postgresql\pgsql-9.5.0\bin>type nul > E:\PGSQLData\pgsql-9.5\_test_write_permission.txt
C:\Apps\postgresql\pgsql-9.5.0\bin>type nul > C:\Apps\postgresql\pgsql-9.4.5.3\bin\_test_write_permission.txt
C:\Apps\postgresql\pgsql-9.5.0\bin>type nul > C:\Apps\postgresql\pgsql-9.5.0\bin\_test_write_permission.txt
</code></pre>
<p>So now I'm even more puzzled than before...</p>
<hr>
<p>Even more details:</p>
<p>I see that the command to create the internal log file is at <a href="https://github.com/postgres/postgres/blob/master/src/bin/pg_upgrade/option.c#L101" rel="noreferrer">/src/bin/pg_upgrade/option.c#L101</a></p>
<p>Which calls <code>fopen_priv(INTERNAL_LOG_FILE, "a")</code> defined at
<a href="https://github.com/postgres/postgres/blob/master/src/bin/pg_upgrade/file.c#L243" rel="noreferrer">/src/bin/pg_upgrade/file.c#L243</a></p>
<p>But I'm not sure to which directory it is trying to write. If I would know that then I can check the permissions on that directory. </p>
<p>Any ideas?</p>

How to replace a part of a string in an xml file?
|
<p>I have an xml file with something like this:</p>
<pre><code><Verbiage>
The whiskers plots are based on the responses of incarcerated
<Choice>
<Juvenile> juveniles who have committed sexual offenses. </Juvenile>
<Adult> adult sexual offenders. </Adult>
</Choice>
If the respondent is a
<Choice>
<Adult>convicted sexual offender, </Adult>
<Juvenile>juvenile who has sexually offended, </Juvenile>
</Choice>
#his/her_lc# percentile score, which defines #his/her_lc# position
relative to other such offenders, should be taken into account as well as #his/her_lc# T score. Percentile
scores in the top decile (> 90 %ile) of such offenders suggest that the respondent
may be defensive and #his/her_lc# report should be interpreted with this in mind.
</Verbiage>
</code></pre>
<p>I am trying to find a way to parse the xml file (I've been using DOM), search for #his/her_lc# and replace that with "her". I've tried using FileReader,BufferedReader, string.replaceAll, FileWriter, but those didn't work.</p>
<p>Is there a way I could do this using XPath?</p>
<p>Ultimately I want to search this xml file for this string and replace it with another string.</p>
<p>do I have to add a tag around the string I want it parse it that way?</p>
<p>Code I tried:</p>
<pre><code>protected void parse() throws ElementNotValidException {
try {
//Parse xml File
File inputXML = new File("template.xml");
DocumentBuilderFactory parser = DocumentBuilderFactory.newInstance(); // new instance of doc builder
DocumentBuilder dParser = parser.newDocumentBuilder(); // calls it
Document doc = dParser.parse(inputXML); // parses file
FileReader reader = new FileReader(inputXML);
String search = "#his/her_lc#";
String newString;
BufferedReader br = new BufferedReader(reader);
while ((newString = br.readLine()) != null){
newString.replaceAll(search, "her");
}
FileWriter writer = new FileWriter(inputXML);
writer.write(newString);
writer.close();
} catch (ParserConfigurationException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
}
</code></pre>
<p>Code I was given to fix:</p>
<pre><code>try {
File inputXML = new File("template.xml"); // creates new input file
DocumentBuilderFactory parser = DocumentBuilderFactory.newInstance(); // new instance of doc builder
DocumentBuilder dParser = parser.newDocumentBuilder(); // calls it
Document doc = dParser.parse(inputXML); // parses file
doc.getDocumentElement().normalize();
NodeList pList = doc.getElementsByTagName("Verbiage"); // gets element by tag name and places into list to begin parsing
int gender = 1; // gender has to be taken from the response file, it is hard coded for testing purposes
System.out.println("----------------------------"); // new line
// loops through the list of Verbiage tags
for (int temp = 0; temp < pList.getLength(); temp++) {
Node pNode = pList.item(0); // sets node to temp
if (pNode.getNodeType() == Node.ELEMENT_NODE) { // if the node type = the element node
Element eElement = (Element) pNode;
NodeList pronounList = doc.getElementsByTagName("pronoun"); // gets a list of pronoun element tags
if (gender == 0) { // if the gender is male
int count1 = 0;
while (count1 < pronounList.getLength()) {
if ("#he/she_lc#".equals(pronounList.item(count1).getTextContent())) {

How to catch all errors for ExoPlayer?
|
<p>I implemented ExoPlayer as player for my application. But I can´t find out how to catch all ExoPlayer errors to avoid app crash. I added following listener, but it doesn´t catch all errors.</p>
<p>I have to use DRM and it sometimes crash on some problem with it, but I can´t set listener before, because player is NULL.</p>
<pre class="lang-java prettyprint-override"><code>player = ExoPlayerFactory.newSimpleInstance(context, trackSelector, loadControl, drmSessionManager);
player.addListener(new ExoPlayer.EventListener() {
@Override
public void onTimelineChanged(Timeline timeline, Object manifest) {
}
@Override
public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {
}
@Override
public void onLoadingChanged(boolean isLoading) {
}
@Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
}
@Override
public void onPlayerError(ExoPlaybackException error) {
//Catch here, but app still crash on some errors!
}
@Override
public void onPositionDiscontinuity() {
}
});

How to get WPF ContentControl content to stretch?
|
<p>I'm using a <code>ContentControl</code> to render various <code>UserControl</code> derivations dynamically. I can't for the life of me figure out how to get the content to stretch when I resize the parent <code>Window</code>. I've found many references like <a href="https://stackoverflow.com/questions/6767613/wpf-usercontrol-is-not-filling-parent-container-when-bound-at-runtime">this</a>, but it's still not working for me. Here is a simple example:</p>
<p>This is the <code>Window</code> XAML:</p>
<pre><code><Window x:Class="WpfApplication3.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<ResourceDictionary Source="Dictionary1.xaml"/>
</Window.Resources>
<Grid>
<ContentControl VerticalAlignment="Top"
HorizontalAlignment="Left"
VerticalContentAlignment="Stretch"
HorizontalContentAlignment="Stretch"
Content="{Binding Path=ChildView}"
Margin="10"/>
</Grid>
</Window>
</code></pre>
<p>This uses the resource file <code>Dictionary1.XAML</code>:</p>
<pre><code><ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:viewModels ="clr-namespace:WpfApplication3"
xmlns:views ="clr-namespace:WpfApplication3">
<DataTemplate DataType="{x:Type viewModels:UserControlViewModel}">
<views:UserControl1/>
</DataTemplate>
</ResourceDictionary>
</code></pre>
<p>Here is the code behind for the main <code>Window</code> as well as the view model classes:</p>
<pre><code>public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
this.DataContext = new MainViewModel();
}
}
public class MainViewModel
{
public UserControlViewModel ChildView { get; set; }
public MainViewModel()
{
ChildView = new UserControlViewModel();
}
}
public class UserControlViewModel
{
}
</code></pre>
<p>and finally the user control:</p>
<pre><code><UserControl x:Class="WpfApplication3.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
Background="Blue"
Height="141" Width="278"
VerticalAlignment="Stretch"
HorizontalAlignment="Stretch">
<Grid>
</Grid>
</UserControl>
</code></pre>
<p>Here's what it looks like at run time:</p>
<p><img src="https://i.stack.imgur.com/4s0LK.png" alt="enter image description here">
<img src="https://i.stack.imgur.com/KVa1i.png" alt="enter image description here"></p>
<p>What am I missing here? How can I get the child content to behave such that it remains anchored to the top/left of the parent and the bottom/right stretches as the parent is resized?</p>

What does the `Target Platform Version` mean for a VS C++ project?
|
<h2>BACKGROUND</h2>
<p>As I understand it, in a C++ project:</p>
<ul>
<li>Project Properties => Configuration Properties => General => <em>Platform Toolset</em>
<ul>
<li>Tells the compiler which SDK to physically compile against.</li>
<li>For example: v140 will tell Visual Studio 2015 to use the latest and greatest v8.1 Windows SDK</li>
</ul>
</li>
<li><code>_WIN32_WINNT</code>, <code>WINVER</code>, and <code>NTDDI_VERSION</code> macros
<ul>
<li>Depending on the underlying operating system, an SDK function can have a different function signature from OS-to-OS.</li>
<li>SDKs are suppose to be backward compatible. <a href="http://www.kndr.org/windows-sdk-brokenness" rel="noreferrer" title="Windows SDK Brokenness">1</a></li>
<li>The before mentioned macros enable you to specify which version of a function you wish to compile against.</li>
</ul>
</li>
</ul>
<h2>MY QUESTION</h2>
<p>If I compile my application with the following setup:</p>
<ul>
<li>project properties => configuration properties => General => <em>Platform Toolset</em>
<ul>
<li>set to: <code>v140_xp</code> (Visual Studio 2015 - Windows XP)</li>
<li>Setting tells compiler to use the 7.1 SDK, which makes sense.</li>
</ul>
</li>
<li>content of: <code>StdAfh.h</code>
<ul>
<li><code>#include <WinSDKVer.h></code></li>
<li><code>#define _WIN32_WINNT 0x0501</code></li>
<li><code>#define WINVER 0x0501</code></li>
<li><code>#define NTDDI_VERSION 0x05010000</code></li>
<li><code>#include <SDKDDKVer.h></code></li>
<li>Macros tell compiler which function signatures to use, which makes sense.</li>
</ul>
</li>
</ul>
<p>From what I can tell, it looks like <em>Target Platform Version</em> is an suposed to be an alternative to the <code>_WIN32_WINNT</code>, <code>WINVER</code>, and <code>NTDDI_VERSION</code> macros. The weird thing is, with the above configuration you can set the <em>Target Platform Version</em> to <code>1</code> or <code>99</code>... and the compiler doesn't generate any errors or warnings.</p>
<p>This this leaves me wondering: <strong>What is the <em>Target Platform Version</em> for?</strong></p>

<p>I have no idea what I need to do to fix this. Eventually I would be able to put all dependencies that I need in a <code>requirements.txt</code> file, so that I can install devendencies in a <code>virtualenv</code>. With that in mind, I would prefer a solution that uses <code>pip</code> as opposed to <code>apt-get</code> or installing from source.</p>

React useRef hook causing "Cannot read property '0' of undefined" error
|
<p>I'm trying to create a reference using the <code>useRef</code> hook for each items within an array of `data by doing the following:</p>
<pre><code>const markerRef = useRef(data.posts.map(React.createRef))
</code></pre>
<p>Now, <code>data</code> is fetched externally through GraphQL and it takes time to arrive, therefore, during the mounting phase, <code>data</code> is <code>undefined</code>. This causes the following error:</p>
<blockquote>
<p>TypeError: Cannot read property '0' of undefined</p>
</blockquote>
<p>I've tried the following with no success:</p>
<pre><code>const markerRef = useRef(data && data.posts.map(React.createRef))
</code></pre>
<p>How do I set up so that I can map through the <code>data</code> without causing the error?</p>
<pre><code> useEffect(() => {
handleSubmit(navigation.getParam('searchTerm', 'default value'))
}, [])
const [loadItems, { called, loading, error, data }] = useLazyQuery(GET_ITEMS)
const markerRef = useRef(data && data.posts.map(React.createRef))
const onRegionChangeComplete = newRegion => {
setRegion(newRegion)
}
const handleSubmit = () => {
loadItems({
variables: {
query: search
}
})
}
const handleShowCallout = index => {
//handle logic
}
if (called && loading) {
return (
<View style={[styles.container, styles.horizontal]}>
<ActivityIndicator size="large" color="#0000ff" />
</View>
)
}
if (error) return <Text>Error...</Text>
return (
<View style={styles.container}>
<MapView
style={{ flex: 1 }}
region={region}
onRegionChangeComplete={onRegionChangeComplete}
>
{data && data.posts.map((marker, index) => (
<Marker
ref={markerRef.current[index]}
key={marker.id}
coordinate={{latitude: marker.latitude, longitude: marker.longitude }}
// title={marker.title}
// description={JSON.stringify(marker.price)}
>
<Callout onPress={() => handleShowCallout(index)}>
<Text>{marker.title}</Text>
<Text>{JSON.stringify(marker.price)}</Text>
</Callout>
</Marker>
))}
</MapView>
</View>
)
</code></pre>
<p>I'm using the <code>useLazyQuery</code> because I need to trigger it at different times.</p>
<p>Update:</p>
<p>I have modified the <code>useRef</code> to the following on the advise of @azundo:</p>
<pre><code>const dataRef = useRef(data);
const markerRef = useRef([]);
if (data && data !== dataRef.current) {
markerRef.current = data.posts.map(React.createRef);
dataRef.current = data
}
</code></pre>
<p>When I console.log <code>markerRef.current</code>, I get the following result:
<a href="https://i.stack.imgur.com/I1SE6.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/I1SE6.png" alt="enter image description here"></a></p>
<p>which is perfectly fine. However, when I attempt to map each <code>current</code> and invoke <code>showCallout()</code> to open all the callouts for each marker by doing the following:</p>
<pre><code>markerRef.current.map(ref => ref.current && ref.current.showCallout())
</code></pre>
<p>nothing gets executed.</p>
<pre><code>console.log(markerRef.current.map(ref => ref.current && ref.current.showCallout()))
</code></pre>
<p>This shows null for each array.</p>

Dynamically render view in a partial with Rails and jQuery
|
<p>In my app, I have a user profile page that has three tabs and a blank div below it. There is a default tab that is white and two other tabs that are darker and "unselected".</p>
<p>I want to make it so that the content in the div below renders a partial based on which tab is selected.</p>
<p>I already have it working to the point where jQuery allows me to click on the different tabs and it changes the colors of the tabs without a page refresh.</p>
<p>However, I am stuck on how to get the partial to render correctly. Any thoughts on this? I am stuck on how to dynamically call a partial based on which tab is selected in the jQuery and actually am not sure if I need another file to interact with this to make it work. I am relatively new to jQuery in a rails app so I am not sure if I've done everything I need to.</p>
<p>User profile page: app > views > show.html.erb</p>
<pre><code> <ul class="profile-tabs">
<%= link_to "<li class=\"tab selected\">Tab 1</li>".html_safe, userprofile_users_path, remote: true %>
<%= link_to "<li class=\"tab\">Tab 2</li>".html_safe, userprofile_users_path, remote: true %>
<%= link_to "<li class=\"tab\">Tab 3</li>".html_safe, userprofile_users_path, remote: true %>
</ul>
<div id="profile-content">
<!--content goes here -->
</div>
</code></pre>
<p>jQuery: app > assets > javascripts > userprofile.js</p>
<pre><code>$(function() {
$("li.tab").click(function(e) {
e.preventDefault();
$("li.tab").removeClass("selected");
$(this).addClass("selected");
$("#profile-content").html("<%= escape_javascript(render partial:
"How can I make this partial name be generated based on the value of the selected li?")%>");
});
});
</code></pre>
<p>Users Controller: app > controllers > users_controller.rb</p>
<pre><code>class UsersController < ApplicationController
def show
@user = User.find(params[:id])
end
def userprofile
respond_to do |format|
format.js
end
end
end
</code></pre>
<p>There are three partials corresponding to the three tabs, and I need the jQuery to somehow dynamically change the partial being called based on the selected tab.</p>
<p>I'd really appreciate some help with this, or if there is another resource that can answer my question. I have not been able to find anything that directly answers what I am trying to do.</p>
<p>Update ------</p>
<p>I used the solution provided rails_has_elegance but nothing is appearing in the div I am targeting. However, I am seeing this in the rails server output, which seems like it is doing what I want:</p>
<pre><code>Started GET "/users/currentoffers" for 127.0.0.1 at 2013-03-28 21:20:01 -0500

Problem with NTFRS - Missing Sysvol and Netlogon on a 2003 Server
|
<p>This is a problem that is affecting me. Although this description wasn´t written by me (seen at www.experts-exchange.com (1), one of the kind of sites stackoverflow was created because of) it applies 95% to the problem I´m having. Next time I won´t follow MS advice, The domain was working until I tried the suggested solution on the event log ("Enable Journal Wrap Automatic Restore"). What a mistake it was!!!.</p>
<p>Description (as seen in (1)) follows:</p>
<p>(1)
<a href="http://www.experts-exchange.com/OS/Microsoft%5fOperating%5fSystems/Server/Windows%5f2003%5fActive%5fDirectory/Q%5f22871376.html" rel="nofollow noreferrer">http://www.experts-exchange.com/OS/Microsoft%5fOperating%5fSystems/Server/Windows%5f2003%5fActive%5fDirectory/Q%5f22871376.html</a></p>
<p>---------- Cut starts here ---------- </p>
<p>I am having some apparently serious problems with a 2003 SBS server.</p>
<p>We have just started the process of putting in a second Domain Controller into this network for a project.</p>
<p>I performed the same task in a lab environment before I started on the live environment, and had no problems.</p>
<p>Firstly, we upgraded the SBS (tisserver) to 2003 R2. After that, I did the adprep to update the schema to R2.</p>
<p>I built up the 2003 R2 server (tisdr), installed DNS, joined it to the domain and did a DCPROMO.</p>
<p>This all worked fine, but I discovered errors in the File Replicaction Service event log on the new server:</p>
<hr>
<p>Event ID 13508 - Source NtFRS</p>
<hr>
<p>The File Replication Service is having trouble enabling replication from tisserver.TIS.local to TISDR for c:\windows\sysvol\domain using the DNS name tisserver.TIS.local. FRS will keep retrying.
Following are some of the reasons you would see this warning.</p>
<p>[1] FRS can not correctly resolve the DNS name tisserver.TIS.local from this computer.
[2] FRS is not running on tisserver.TIS.local.
[3] The topology information in the Active Directory for this replica has not yet replicated to all the Domain Controllers.</p>
<p>This event log message will appear once per connection, After the problem is fixed you will see another event log message indicating that the connection has been established.</p>
<p>For more information, see Help and Support Center at <a href="http://go.microsoft.com/fwlink/events.asp" rel="nofollow noreferrer">http://go.microsoft.com/fwlink/events.asp</a>.</p>
<hr>
<p>When I went and checked the SBS, I found the following error had been occurring:</p>
<hr>
<p>Eventid ID 13568 - Source NtFrs</p>
<hr>
<p>The File Replication Service has detected that the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" is in JRNL_WRAP_ERROR.</p>
<p>Replica set name is : "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)"
Replica root path is : "c:\windows\sysvol\domain"
Replica root volume is : "\.\C:"
A Replica set hits JRNL_WRAP_ERROR when the record that it is trying to read from the NTFS USN journal is not found. This can occur because of one of the following reasons.</p>
<p>[1] Volume "\.\C:" has been formatted.
[2] The NTFS USN journal on volume "\.\C:" has been deleted.
[3] The NTFS USN journal on volume "\.\C:" has been truncated. Chkdsk can truncate the journal if it finds corrupt entries at the end of the journal.
[4] File Replication Service was not running on this computer for a long time.
[5] File Replication Service could not keep up with the rate of Disk IO activity on "\.\C:".
Setting the "Enable Journal Wrap Automatic Restore" registry parameter to 1 will cause the following recovery steps to be taken to automatically recover from this error state.
[1] At the first poll, which will occur in 5 minutes, this computer will be deleted from the replica set. If you do not want to wait 5 minutes, then run "net stop ntfrs" followed by "net start ntfrs" to restart the File Replication Service.
[2] At the poll following the deletion this computer will be re-added to the replica set. The re-addition will trigger a full tree sync for the replica set.</p>
<p>WARNING: During the recovery process data in the replica tree may be unavailable. You should reset the registry parameter described above to 0 to prevent automatic recovery from making the data unexpectedly unavailable if this error condition occurs again.</p>
<p>To change this registry parameter, run regedit.</p>
<p>Click on Start, Run and type regedit.</p>
<p>Expand HKEY_LOCAL_MACHINE.
Click down the key path:
"System\CurrentControlSet\Services\NtFrs\Parameters"
Double click on the value name
"Enable Journal Wrap Automatic Restore"
and update the value.</p>
<p>If the value name is not present you may add it with the New->DWORD Value function under the Edit Menu item. Type the value name exactly as shown above.</p>
<p>For more information, see Help and Support Center at <a href="http://go.microsoft.com/fwlink/events.asp" rel="nofollow noreferrer">http://go.microsoft.com/fwlink/events.asp</a>.</p>
<hr>
<p>After doing a bit of reading, it seemed like the right thing to do was a non-authoritative resotre, so I went through and created the registry key, then stopped and started the NTFRS service.</p>
<p>As expected, I got:</p>
<hr>
<p>EventID 13560 - Source NtFRS</p>
<hr>
<p>The File Replication Service is deleting this computer from the replica set "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)" as an attempt to recover from the error state,
Error status = FrsErrorSuccess
At the next poll, which will occur in 5 minutes, this computer will be re-added to the replica set. The re-addition will trigger a full tree sync for the replica set.</p>
<p>For more information, see Help and Support Center at <a href="http://go.microsoft.com/fwlink/events.asp" rel="nofollow noreferrer">http://go.microsoft.com/fwlink/events.asp</a>.</p>
<hr>
<p>Exactly five minutes later, I got:</p>
<hr>
<p>EventID 13520 - Source NtFRS</p>
<hr>
<p>The File Replication Service moved the preexisting files in c:\windows\sysvol\domain to c:\windows\sysvol\domain\NtFrs_PreExisting___See_EventLog.</p>
<p>The File Replication Service may delete the files in c:\windows\sysvol\domain\NtFrs_PreExisting___See_EventLog at any time. Files can be saved from deletion by copying them out of c:\windows\sysvol\domain\NtFrs_PreExisting___See_EventLog. Copying the files into c:\windows\sysvol\domain may lead to name conflicts if the files already exist on some other replicating partner.</p>
<p>In some cases, the File Replication Service may copy a file from c:\windows\sysvol\domain\NtFrs_PreExisting___See_EventLog into c:\windows\sysvol\domain instead of replicating the file from some other replicating partner.</p>
<p>Space can be recovered at any time by deleting the files in c:\windows\sysvol\domain\NtFrs_PreExisting___See_EventLog.</p>
<p>For more information, see Help and Support Center at</p>
<hr>
<p>&</p>
<hr>
<p>EventID 13553 - Source NtFRS</p>
<hr>
<p>The File Replication Service successfully added this computer to the following replica set:
"DOMAIN SYSTEM VOLUME (SYSVOL SHARE)"</p>
<p>Information related to this event is shown below:
Computer DNS name is "tisserver.TIS.local"
Replica set member name is "TISSERVER"
Replica set root path is "c:\windows\sysvol\domain"
Replica staging directory path is "c:\windows\sysvol\staging\domain"
Replica working directory path is "c:\windows\ntfrs\jet"</p>
<p>For more information, see Help and Support Center at</p>
<hr>
<p>---------- Cut ends here ---------- </p>
<p>From this point on the responses I got start to drift from the original poster:</p>
<hr>
<p>EventID 13566 - Source NtFRS</p>
<hr>
<p>File Replication Service is scanning the data in the system volume. Computer DOMSERVER cannot become a domain controller until this process is complete. The system volume will then be shared as SYSVOL. </p>
<p>To check for the SYSVOL share, at the command prompt, type:
net share </p>
<p>When File Replication Service completes the scanning process, the SYSVOL share will appear. </p>
<p>The initialization of the system volume can take some time. The time is dependent on the amount of data in the system volume.</p>
<p>For more information, see Help and Support Center at <a href="http://go.microsoft.com/fwlink/events.asp" rel="nofollow noreferrer">http://go.microsoft.com/fwlink/events.asp</a>.</p>
<hr>
<p>I have left it for about an hour and a half now, and am not seeing any sign of a sysvol or netlogon share yet. The users are unable to log on. I don´t know where to go to from here. I´m in such desperate state that, if I had the money, I sure would pay experts-exchange (and the bad guys would win, I know :( ). Unfortunaly, I can´t do that for many reasons (not having a credit card is one of them).</p>
<p>Your help would be greatly appreciated!</p>
<p>PS: sorry for my not so good english. It´s not my mother tongue. Next time I will be better at it. :)</p>

PHP : How to put and pass variable in modal URL
|
<p>So, I have a button to give a direct link to modal in same page.</p>
<p>this is the button and url</p>
<pre><code><a data-toggle="modal"
href="main_user.php?user_id=<?php echo $user['user_id']; ?>#myModal"
class="btn btn-warning">
</code></pre>
<p>( I try to echo the <code>$user_id</code> on before <code>#modal</code> ) is it right ?</p>
<p>and after I click the button, the modal will appear.
This is the modal with the form.</p>
<pre><code><form class="form-login" action="action/doEditUserStatus.php" method="post">
<div class="login-wrap">
<div class="changestatus">
<p>Banning or Activing User Status</p></div>
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-success active">
<input type="radio" name="options" value="1" autocomplete="off" checked> Actived
</label>
<label class="btn btn-primary">
<input type="radio" name="options" value="2" autocomplete="off"> Banned
</label>
</div>
</div>
<div class="modal-footer">
<button data-dismiss="modal" class="btn btn-default" type="button">Cancel</button>
<button class="btn btn-theme" name="modalSubmit" type="submit">Submit</button>
</div>
</form>
</code></pre>
<p>And then I try to submit the modal form, but the action cannot read the <code>$user_id</code> which I put before <code>#modal</code>.</p>
<p>UPDATE :
Table code :</p>
<p>So this is my table :</p>
<pre><code><tr class="success">
<th class="numeric">ID</th>
<th class="numeric">E-mail</th>
<th class="numeric">Name</th>
<th class="numeric">Phone</th>
<th class="numeric">Picture</th>
<th class="numeric">Status</th>
<th colspan="2" class="numeric">Action</th>
</tr>
<tr>
<td class="numeric"><?php echo $user['user_id']; ?></td>
<td class="numeric"><?php echo $user['email']; ?></td>
<td class="numeric"><?php echo $user['name']; ?></td>
<td class="numeric"><?php echo $user['phone']; ?></td>
<td class="numeric"><?php echo $user['picture']; ?></td>
<td class="numeric">
<a data-toggle="modal" href="main_user.php?user_id=<?php echo $user['user_id']; ?>#myModal" class="btn btn-warning">
<span class="glyphicon glyphicon-edit" aria-hidden="true"></span>&nbsp;Change Status
</a>
</td>
</tr>
</code></pre>
<p>The main problem is :
When I click the button, then the modal will appear but it can't get the <code>$user_id</code> from that button?</p>

WCF logging, set max file size?
|
<p>Im using Microsoft Service Configuration Editor to setup diagnostics(WCF logging) and I can´t find any way to set the max file size?</p>
<p>I have found the MaxSizeOfMessageToLog but that do nothing about the file size?</p>
<p><strong>Edit 1:</strong> According to this : <a href="http://msdn.microsoft.com/en-us/library/aa395205.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/aa395205.aspx</a>
There should be a maxFileSizeKB at the sharedListeners level but when hitting space in the add tag I do not get the possibility to type maxFileSizeKB?</p>
<p><strong>Edit 2:</strong> When adding the maxFileSizeKB the serivce will not start anymore, instead I will get the following excetion : </p>
<p><em>'maxFileSizeKB' is not a valid configuration attribute for type 'System.Diagnostics.XmlWriterTraceListener'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Configuration.ConfigurationErrorsException: 'maxFileSizeKB' is not a valid configuration attribute for type 'System.Diagnostics.XmlWriterTraceListener'.
Source Error:
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.</em></p>
<p>Edit 3 :</p>
<p>I had to download the Circular TraceListener sample and include it in my project, there is no built in fileSize limiter.</p>
<p>My config looks like this now : </p>
<pre><code><system.diagnostics>
<sources>
<source name="System.ServiceModel.MessageLogging" switchValue="Warning, ActivityTracing">
<listeners>
<add name="ServiceModelMessageLoggingListener"/>
</listeners>
</source>
<source name="System.ServiceModel" switchValue="Warning,ActivityTracing"
propagateActivity="false">
<listeners>
<add name="ServiceModelTraceListener"/>
</listeners>
</source>
</sources>
<sharedListeners>
<add initializeData="C:\My\MyRelease 0.31\Host\My.Host.Dev\web_messages.svclog"
type="Microsoft.Samples.ServiceModel.CircularTraceListener,CircularTraceListener"
name="ServiceModelMessageLoggingListener" traceOutputOptions="Timestamp" maxFileSizeKB="1024">
<filter type="" />
</add>
<add initializeData="C:\My\MyRelease 0.31\Host\My.Host.Dev\web_tracelog.svclog"
type="Microsoft.Samples.ServiceModel.CircularTraceListener,CircularTraceListener"
name="ServiceModelTraceListener" traceOutputOptions="Timestamp" maxFileSizeKB="1024">
<filter type="" />
</add>
</sharedListeners>
</code></pre>
<p>This is limiting the message log file but not the trace log file?</p>

WebGL Unavailable, GPU Process unable to boot
|
<p>I'm running Chrome 54.0.2840.87 on Windows 10. I have two GPUs: an Intel(R) HD Graphics 520, and a AMD Radeon R5 M335.</p>
<p>Up until a couple of weeks ago, WebGL was running just fine in chrome. Now, after not having changed any settings anywhere, WebGL is no longer available.</p>
<p>When trying to run a chrome experiment for example, I get a message saying that my graphics card does not seem to support WebGL. I know my graphics cards work fine (they have been updated with the latest drivers), plus WebGL runs perfectly in firefox. I know my GPUs have not been blacklisted (on either browser).</p>
<p>On <code>chrome:gpu</code>, I am told that WebGL is unavailable, and that the GPU process was unable to boot. When checking <code>chrome:flags</code> enabling or disabling WebGL no longer seems to be an option.</p>
<p>Enabling/disabling anything else that involves WebGL has not made any difference. Is there something else that can be done to get it working again? At what level is the issue? (The issue persists on Chrome Canary.) I am not the most technologically savvy person, but I've had no luck finding answers anywhere else.</p>
<p>The following is what I see on my <code>chrome:gpu</code> page:</p>
<p><strong>Graphics Feature Status</strong></p>
<blockquote>
<p>Canvas: Software only, hardware acceleration unavailable</p>
<p>Flash: Software only, hardware acceleration unavailable</p>
<p>Flash Stage3D: Software only, hardware acceleration unavailable</p>

How do I find out how macPorts stole my port:80?
|
<p>I had MAMP installed (and working fine) then I tried to install mongoDB through macPorts. macports then began installing a bunch of dependencies. after that, <a href="http://localhost" rel="noreferrer">http://localhost</a> started giving an "It Works!" screen. after rebooting to see if it might fix it, I found that I could not start my MAMP server. console said this:</p>
<pre><code>9/13/10 1:20:54 PM [0x0-0x12012].de.appsolute.MAMP[133] (48)Address already in use: make_sock: could not bind to address [::]:80
</code></pre>
<p>I know that macPorts did something stupid to mess with me. how can I find out what it installed thats stealing port:80?</p>
<p>here's some command I've tried: (:80 didn't work, so I just used 80)</p>
<pre><code>$ sudo netstat -an | grep 80
Password:
tcp46 0 0 *.80 *.* LISTEN
udp6 0 0 fe80::21e:52ff:f.123 *.*
udp6 0 0 fe80::1%lo0.123 *.*
</code></pre>
<p>and:</p>

IFrame OnReadyStateChange function
|
<p>I have an asp.webforms application and on page a i have a hidden div with progressbar and iframe. To iframe i try loaded form from another application on same domain.</p>
<pre><code><div id="pagePreview" style="display: none;">
<div class="progressBarWrapper" id="waitDialog" style="opacity:1;filter:alpha(opacity=100);display:none;">
<div class="progressBarDetail" style="margin-top:25%;">
<asp:Image ID="imgLoading" runat="server" ImageUrl="~/Images/wait.gif" />
</div>
</div>
<iframe id="previewContent" onreadystatechange="iframeLoaded(this);"></iframe>
</div>
</code></pre>
<p>On a click event i call a function to show this div in jqueryUI dialog and i Want show progressbar until the page in Iframe is not loaded.</p>
<pre><code>var isClickedForDialog = false;
function iframeLoaded(args) {
if (args.readyState == "complete" && isClickedForDialog) {
var pagePreview = $('#pagePreview'); // dialog
var waitDialog = $('#waitDialog'); // progress
waitDialog.hide();
isClickedForDialog = false;
}
}
function showModalWindow(url, hideCloseButton) {
isClickedForDialog = true;
var previewContent = $('#previewContent'); // Iframe
var pagePreview = $('#pagePreview'); // dialog
var waitDialog = $('#waitDialog'); // progresss
waitDialog.show();
previewContent.attr('src', url);
pagePreview.dialog(
{
draggable: false,
resizable: false,
height: 764,
width: 1020,
modal: true,
close: function (event, ui) {
previewContent.attr('src', '');
},
open: function (event, ui) {
if (hideCloseButton) {
$(this).parent().children().children('.ui-dialog-titlebar-close').hide();
}
}
});
}
</code></pre>
<p>In IE everything works fine. The dialog box and progressbar displays and when the URL is loaded in an iframe, progressbar disappears and i see only webforms in IFrame.</p>
<p>But in FireFox and Chrome this does not work.</p>
<p>The browser ignores the onreadystatechange event. I tried to handle an event as following:</p>
<pre><code>$('#previewContent').bind('onreadystatechange', iframeLoaded, false);
$('#previewContent').on('onreadystatechange', iframeLoaded);
</code></pre>
<p>but without success.</p>
<p>know how to solve this? thanks</p>

How come jobParameters cannot be found in ItemProcessor using annotations?

<p>I am having issues using the job parameters in my item processor. At this time, the code is basically setup like: <a href="https://stackoverflow.com/questions/31737209/how-to-get-job-parameteres-in-to-item-processor-using-spring-batch-annotation">How to get Job parameteres in to item processor using spring Batch annotation</a> but I am receiving an error at runtime. Also, please note that my example code does use some spring integration for processing. </p>

How do I make Firefox reload page when back button is pressed?
|
<p>I have tried every combination and permutation of meta tags that are supposed to stop a page from being cached, but Firefox STILL caches the page! <strong>I just need the URL to reload when a user presses the back button.</strong> Works fine in IE8.</p>
<p>I have tried all of these...</p>
<pre><code><meta http-equiv="Cache-Control" content="no-store" />
<meta http-equiv="Pragma" content="no-cache"/>
<meta http-equiv="Expires" content="-1"/>
<meta http-equiv="Expires" content="Sat, 1 Jan 2000 00:00:00 GMT" />
</code></pre>
<p>...and I have also tried the following JavaScript...</p>
<pre><code><input type="hidden" id="refreshed" value="no"/>
<script type="text/javascript">
onload=function(){
var e=document.getElementById("refreshed");
if(e.value=="no"){
e.value="yes";
}
else{
e.value="no";
location.reload();
}
}
</script>
</code></pre>
<p>... all to no avail. What am I missing here? Pages are generated with PHP if that matters.</p>
<p><strong>UPDATE 1:</strong></p>
<p>I have tried every suggestion thus far but I still cannot get this to work. When I use Chris's PHP code I use it like this...</p>
<pre><code><?php
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html dir="ltr" xmlns="http://www.w3.org/1999/xhtml">
<!--the rest of my page-->
</code></pre>
<p>.. and as you can see it is at the EXTREME top of my webpage, before the <code>DOCTYPE</code> header.</p>
<p>I have also experimented with <code>session_start()</code> but even after reading the manual I am not sure I am using it right. I was putting it right at the very top of my page as well.</p>
<p><strong>I am open to ANY SUGGESTIONS that make this work without breaking other page functionality. I know I have seen pages that reload EVERY TIME the back button is used, HOW ARE THEY DOING IT?!</strong></p>
<p><strong>SOLVED!</strong></p>
<p>Turns out I had multiple issues working against me, but through due diligence I was able to eliminate those issues and emerge victorious.</p>
<p>After Chris updated his code to...</p>
<pre><code><?php
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
echo time();
?><a href="http://google.com">aaaaaaaaaaaaa</a>
</code></pre>
<p>I found that his code did indeed work when I used it EXACTLY how he had it with NOTHING else, but when I put it into my pages it didn't work. All of my pages are either <code>.php</code> or <code>.html</code> and all are attached to a DWT (Dynamic Web Template), so I was updating all of them at once with Chris's code. What I didn't realize was that the DWT starts RIGHT AFTER the <code>DOCTYPE</code> header, so the code was never inserted into my pages. I could find no way to make the DWT include the <code>DOCTYPE</code> header so I went into all my pages and manually inserted the code above the <code>DOCTYPE</code> header.</p>
<p>Next I found that even though my server is set to parse <code>.htm</code> and <code>.html</code> as <code>.php</code> the <code>.html</code> pages were generating an error at the very where I had inserted Chris's code saying something to the effect of "cannot modify headers, headers have already been sent". I didn't really care what my extensions were so I just changed all my <code>.html</code> extensions to <code>.php</code> extensions.</p>
<p>A final minor annoyance was that even though the page was now not being cached (just like I wanted) Firefox was placing the user at their last location on the previous page when they used the back button (i.e. if a user was at the bottom of page a when they navigated to page b, then the user used the back button on page b they would be returned to the bottom of page a, not the top of page a as desired). Trimming down my original JavaScript fixed this...</p>
<pre><code> <script type="text/javascript">
onload=function(){
document.getElementById('content').scrollTop=0;
}
</script>
</code></pre>
<p>Even though this seems very involved for such a simple problem I am glad it is fixed. Thanks for your help everyone (especially Chris).</p>

jQuery Ajax does not update the result inside the div

error C2143: syntax error : missing ';' before '*'
|
<p>I'm not new to C++ but I am used to running a g++ compiler vs Microsoft's VS C++. I understand what this error should mean. It should mean that I'm missing a ';' on the line before or in the class Polygon. I can't seem to find anything wrong. g++ compiles the code without error. It seems like the Polygon Class isn't being loaded. Can anyone please show me what I'm missing please.I have the Application.cpp, Polygon.h, and Polygon.cpp below.</p>
<p>Application.cpp throwing errors but if I can fix the first others will follow:</p>

Can't resolve all parameters for Router: (?, ?, ?, ?, ?, ?, ?) in Angular RC 5 when unit testing
|
<p>I just upgraded to Angular RC 5 and now all component that uses 'ROUTER_DIRECTIVES' fails with 'Can't resolve all parameters for Router: (?, ?, ?, ?, ?, ?, ?)' when I try to unit test the component. </p>
<pre><code>import { inject, addProviders } from '@angular/core/testing';
import { ComponentFixture, TestComponentBuilder } from '@angular/core/testing';
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES, Router } from '@angular/router';
import { HomeComponent } from './home.component';
import { UserService } from '../_services/user.service';
describe('Component: Home', () => {
beforeEach(() => {
addProviders([HomeComponent, UserService, ROUTER_DIRECTIVES, Router]);
});
it('should inject the component', inject([HomeComponent, UserService, ROUTER_DIRECTIVES, Router],
(component: HomeComponent) => {
expect(component).toBeTruthy();
// expect(component.currentUser.firstname).toEqual('Jan');
}));

Having Troubles with UnixODBC, FreeTDS, and PyODBC

<p>I am having great difficulty getting all three of these to work together in harmony. I guess I'll list all the various configurations, along with the test code to see if a pair of fresh eyes can realize my stupidity.</p>

Can't click anything after i open my Bootstrap modal
|
<p>sorry for the basic question, I'm working on MVC ASP.NET and I'm trying to add a bootstrap modal in my navbar, I run the code, i can see the button i can touch on it, but after it open, the screen is unclickable i have to f5 to click anywhere again, it's the first time i use modals from bootstrap, and search all around google if I have to write some JavaScript code, but everywhere says that you just need jquery , bootstrap.js and .css and nothing else. If I'm missing something just let me know. Thanks, Here is my code.</p>

How To Add a jFreeChart to a jPanel in a jFrame?

Why are KD-trees so damn slow for nearest neighbor search in point sets?
|
<p>I am using CGAL's (the latest) KD-tree implementation for searching nearest neighbors in point sets. And also Wikipedia and other resources seem to suggest that KD-trees are the way to go. But somehow they are too slow and Wiki also suggests their worst-case time of O(n), which is far from ideal.</p>
<p>[BEGIN-EDIT]
<strong>I am now using "nanoflann", which is about 100-1000 times faster than the equivalent in CGAL for K-neighbor search. And I am using "Intel Embree" for raycasting, which is about 100-200 times faster than CGAL's AABB trees.</strong>
[END-EDIT]</p>
<p>My task looks like this:</p>
<p>I have a HUGE point set, say like up to a few 100 mio. points!! and their distribution is on surfaces of triangulated geometry (yes, a photon tracer). So one could say that their distribution is 2D in 3D space, because it is sparse in 3D but dense when looking at the surfaces... This could be the problem right? Because to me this seems to trigger the worst-case performance of a KD-tree which probably could deal much better with 3D dense point sets...</p>
<p>CGAl is quite good at what it does, so I have a bit doubt that their implementation just sucks. Their AABB tree I am using for raytracing burns a straight billion raytraces in a few mintues in the ground... That is remarkable I guess. But their KD-tree on the other hand can't even deal with a mio. points and 250k samples (point queries) in any reasonable time...</p>
<p>I came up with two solutions which kick the crap out of KD-trees:</p>
<p>1) Use texture maps to store the photons in a linked list on the geometry. This is always an O(1) operation, since you have to do the raycast anyway...</p>
<p>2) Use view dependent sliced hashsets. That is the farther away you get, the more coarse the hashsets get. So basically you can think of a 1024x1024x1024 raster in NDC coordinates, but with hashsets, to save memory in sparse areas. This basically has O(1) complexity and can be parallelized efficiently, both for inserts (micro-sharding) and queries (lock-free). </p>
<p>The former solution has the disadvantage that it is close to impossible to average over neighboring photon lists, which is important in darker regions to avoid noise.
The latter solution doesn't have this problem and should be on par feature wise with KD-trees, just that it has O(1) worst case performance, lol.</p>
<p>So what do you think? Bad KD-tree implementation? If not, is there something "better" than a KD-tree for bounded nearest neighbor queries? I mean I have nothing against my second solution above, but a "proven" data-structure that delivers similar performance would be nicer!</p>
<p>Thanks!</p>

OnScreen keyboard opens automatically when Activity starts
|
<p>When my Activity with a <code>ScrollView</code> layout and <code>EditText</code>s starts, the <code>EditText</code>s get focus and the Android OnScreen keyboard opens.</p>
<p>How I can avoid that?</p>
<p>When I was using <code>LinearLayout</code> and <code>RelativeLayout</code> without the <code>ScrollView</code> it doesn't happen.</p>
<p>I've tried it this way, and it works, but it's not a good way to do it:</p>
<pre><code>TextView TextFocus = (TextView) findViewById(R.id.MovileLabel);
TextFocus.setFocusableInTouchMode(true);
TextFocus.requestFocus();
</code></pre>
<p>Next you have an example of some of my layouts with this problem, when this Activity starts, focus goes to the first <code>EditText</code>, <em>Description</em> and the Android keyboard opens automatically, this is very annoying.</p>

Dynamically adding rows to datatable using ajax with pagination and sorting
|
<p>I am trying to achieve <a href="https://almsaeedstudio.com/themes/AdminLTE/pages/tables/data.html" rel="nofollow noreferrer">https://almsaeedstudio.com/themes/AdminLTE/pages/tables/data.html</a> - "Data Table With Full Features"</p>
<p>When I added tbody statically, pagination and sorting works fine but when I add tbody using jquery as given below, rows are added but pagination and sorting fails.</p>
<p><strong>HTML</strong></p>
<pre><code><table id="tblItems">
<thead>
<tr>
<th>code</th>
<th>Name</th>
<th>Description</th>
<th>Image</th>
<th>Parent</th>
<th>Location</th>
<th>Category</th>
</tr>

<p>The updated code doesn't populate the table though there are data from the response. Though I set the deferRender to true, still the datatable is empty.</p>

<p>With the help of people answered below, the code below works as expected.</p>

@ModelAttribute controller spring-mvc mocking
|
<p>I want to test a controller which is using <code>@ModelAttribute</code> for one of its method arguments.</p>
<pre><code>public String processSaveAction(@ModelAttribute("exampleEntity") ExampleEntity exampleEntity)
</code></pre>
<p><code>@ModelAttribute</code> method <code>getExampleEntity</code> is using <code>@RequestParam</code>:</p>
<pre><code>@ModelAttribute("exampleEntity")
public ExampleEntity getExampleEntity(@RequestParam(value = "id", required = true) ExampleEntity exampleEntity) {
</code></pre>
<p>My controller is using <code>WebDataBinder</code> to call a factory, which returns an object based on param "id".</p>
<pre><code>@Controller
public class ExampleController(){
@Autowired private IdEditorFactory idEditorFactory;
@InitBinder
public void initBinder(WebDataBinder binder) {
binder.registerCustomEditor(ExampleEntity.class, idEditorFactory.createEditor(ExampleEntity.class));
}
@ModelAttribute("exampleEntity")
public ExampleEntity getExampleEntity(@RequestParam(value = "id", required = true) ExampleEntity exampleEntity) {
//Irrelevant operations
return exampleEntity;
}
@RequestMapping(method = RequestMethod.POST, params = "action=save")
public String processSaveAction(
@RequestParam(value = "confirmed") String exampleString,
@ModelAttribute("exampleEntity") ExampleEntity exampleEntity,
BindingResult result, HttpServletRequest request)
throws IOException {
boolean success = editorProcessor.processSaveAction(exampleString,
exampleEntity, result, request);
return success ? getSuccessView(exampleEntity) : VIEW_NAME;
}
}
</code></pre>
<p>And my test:</p>
<pre><code>@WebAppConfiguration
public class ExampleControllerTest{
@Mock private EditorProcessor editorProcessor;
@Mock private IdEditorFactory idEditorFactory;
@InjectMocks private ExampleController exampleController;
private MockMvc mockMvc;
@Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
mockMvc = MockMvcBuilders.standaloneSetup(exampleController).build();
WebDataBinder webDataBinder = new WebDataBinder(ExampleEntity.class);
webDataBinder.registerCustomEditor(ExampleEntity.class, idEditorFactory.createEditor(ExampleEntity.class));
}
@Test
public void shouldProcessSaveAction() throws Exception {
// given
BindingResult result = mock(BindingResult.class);
ExampleEntity exampleEntity = mock(ExampleEntity.class);
HttpServletRequest httpServletRequest = mock(HttpServletRequest.class);
given(editorProcessor.processSaveAction("confirmed", exampleEntity, result, httpServletRequest)).willReturn(true);
// when
ResultActions perform = mockMvc.perform(post("/").sessionAttr("exampleEntity", exampleEntity)
.param("id", "123456"
.param("action","save"));
// then
perform.andDo(print())
.andExpect(status().isOk());
}
}
</code></pre>
<p>I want to somehow mock <code>getExampleEntity()</code> so that every time I perform a POST with parameter "id", I receive a mocked object ("exampleEntity") for the test.</p>
<p>I could introduce <code>@Binding</code> to the test, but then I would have to mock many levels of methods (like initBinder -> idEditoryFactory-> editor -> hibernateTemplate and so on) only to get an entity from some source (for example, a database).</p>

Import Classes Into Java Files
|
<p>I am currently learning to develop in Java and am interested in creating Java classes that other users can import into their program and use. Yes, I know my example class is simple and stupid but I want to learn the concept and start making more complex classes that people can import into their projects.</p>
<p>I created a simple "<em>Logger</em>" class that when called logs both text to the console and to a text file for readability. You can call this class by using the following commands...</p>
<pre><code>Logger Logger = new Logger();
Logger.create();
Logger.log("This text will be logged to the console and log.log");
</code></pre>
<p>See below for the <strong>Logger</strong> class.</p>
<pre><code>import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class Logger {
FileWriter fw;
BufferedWriter br;
File file = new File("log.log");
boolean fileExists = file.exists();
public void log(String message) {
try {
fw = new FileWriter(file, true);
br = new BufferedWriter(fw);
Calendar cal = Calendar.getInstance();
int hour = cal.get(Calendar.HOUR_OF_DAY);
if(hour > 12)
hour = hour - 12;
int minute = cal.get(Calendar.MINUTE);
int second = cal.get(Calendar.SECOND);
int millis = cal.get(Calendar.MILLISECOND);
int ampm = cal.get(Calendar.AM_PM);
String ampmString;
if(ampm == 1)
ampmString = "PM";
else
ampmString = "AM";
String now = String.format("%02d:%02d:%02d.%03d %s", hour, minute, second, millis, ampmString);
System.out.println(now + " - " + message);
br.write(now + " - " + message);
br.newLine();
br.close();
} catch (Exception err) {
System.out.println("Error");
}
}
public void create() {
try {
fw = new FileWriter(file, true);
br = new BufferedWriter(fw);
SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-YYYY");
String dateString = sdf.format(new Date());
if(file.length() != 0)
br.newLine();
System.out.println("Log: " + file.getAbsolutePath());
br.write("--------------------" + dateString + "--------------------");
br.newLine();
br.close();
} catch (Exception err) {
System.out.println("Error");
}
}
}
</code></pre>
<p>The issue I am having is in order to use this class I have to add it to every single project I create and want to use this. Is there a way I can add an import like, <code>mydomain.Logger.*;</code> and be able to access this class and the methods it contains?</p>
<p>My question, <strong>What is the best way to allow anyone to import/use my Logger class in the simplest way? What steps do I need to take to allow them to do this?</strong></p>

Is it fine if first response is private with AppCache (Symfony2)?
|
<p>I'm trying to use http caching. In my controller I'm setting a response as follows: </p>
<pre><code>$response->setPublic();
$response->setMaxAge(120);
$response->setSharedMaxAge(120);
$response->setLastModified($lastModifiedAt);
</code></pre>
<p><strong>dev mode</strong></p>
<p>In dev environment first response is a 200 with following headers:</p>
<pre><code>cache-control:max-age=120, public, s-maxage=120
last-modified:Wed, 29 Feb 2012 19:00:00 GMT
</code></pre>
<p>For next 2 minutes every response is a 304 with following headers:</p>
<pre><code>cache-control:max-age=120, public, s-maxage=120
</code></pre>
<p>This is basically what I expect it to be.</p>
<p><strong>prod mode</strong></p>
<p>In prod mode response headers are different. Note that in app.php I wrap the kernel in AppCache.</p>
<p>First response is a 200 with following headers:</p>
<pre><code>cache-control:must-revalidate, no-cache, private
last-modified:Thu, 01 Mar 2012 11:17:35 GMT
</code></pre>
<p>So it's a private no-cache response.</p>
<p>Every next request is pretty much what I'd expect it to be; a 304 with following headers:</p>
<pre><code>cache-control:max-age=120, public, s-maxage=120
</code></pre>
<p><strong>Should I worry about it? Is it an expected behaviour?</strong> </p>
<p><strong>What will happen if I put Varnish or Akamai server in front of it?</strong></p>
<p>I did a bit of debugging and I figured that response is private because of last-modified header. HttpCache kernel <a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/HttpCache/HttpCache.php#L210">uses EsiResponseCacheStrategy</a> to update the cached response (<a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/HttpCache/HttpCache.php#L171">HttpCache::handle()</a> method). </p>
<pre><code>if (HttpKernelInterface::MASTER_REQUEST === $type) {
$this->esiCacheStrategy->update($response);
}
</code></pre>
<p>EsiResponseCacheStrategy <a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/HttpCache/EsiResponseCacheStrategy.php#L42">turns a response into non cacheable</a> if it uses either Last-Response or ETag (<a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/HttpCache/EsiResponseCacheStrategy.php#L40">EsiResponseCacheStrategy::add()</a> method):</p>
<pre><code>if ($response->isValidateable()) {
$this->cacheable = false;
} else {
// ...
}
</code></pre>
<p><a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpFoundation/Response.php#L407">Response::isValidateable()</a> returns true if Last-Response or ETag header is present.</p>
<p>It results in <a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/HttpCache/EsiResponseCacheStrategy.php#L62">overwriting the Cache-Control header</a> (<a href="https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/HttpCache/EsiResponseCacheStrategy.php#L55">EsiResponseCacheStrategy::update()</a> method):</p>
<pre><code>if (!$this->cacheable) {
$response->headers->set('Cache-Control', 'no-cache, must-revalidate');
return;
}
</code></pre>
<p>I asked this question on Symfony2 user group but I didn't get an answer so far: <a href="https://groups.google.com/d/topic/symfony2/6lpln11POq8/discussion">https://groups.google.com/d/topic/symfony2/6lpln11POq8/discussion</a></p>
<p><strong>Update.</strong></p>
<p>Since I no longer have access to the original code I tried to <a href="https://github.com/jakzal/symfony-standard/blob/cache/src/Acme/DemoBundle/Controller/DemoController.php#L62">reproduce the scenario with the latest Symfony standard edition</a>.</p>
<p>Response headers are more consistent now, but still seem to be wrong. </p>
<p>As soon as I set a <code>Last-Modified</code> header on the response, the first response made by a browser has a: </p>
<pre><code>Cache-Control:must-revalidate, no-cache, private
</code></pre>
<p>Second response has an expected:</p>
<pre><code>Cache-Control:max-age=120, public, s-maxage=120
</code></pre>
<p>If I avoid sending <code>If-Modified-Since</code> header, every request returns <code>must-revalidate, no-cache, private</code>.</p>
<p>It doesn't matter if the request was made in <code>prod</code> or <code>dev</code> environment anymore.</p>

mat-table angular 6 not showing any data despite having the dataSource
|
<p>I want to show a list through Angular material design's data table mat-table.
Here is my component:</p>
<pre><code>import { LeaveapplicationService } from './../../services/leaveapplication.service';
import { leaveapplication } from './../../models/leaveapplication';
import { Component, OnInit, ViewChild, Input } from '@angular/core';
import { MatTableDataSource, MatPaginator, MatSort } from '@angular/material';
// import { DataSource } from '@angular/cdk/table';
@Component({
selector: 'app-leaveapplication-list',
templateUrl: './leaveapplication-list.component.html',
styleUrls: ['./leaveapplication-list.component.scss']
})
export class LeaveapplicationListComponent implements OnInit {
leaveApplications: leaveapplication[];
displayedColumns: ['id', 'applicant', 'manager', 'leavetype', 'start', 'end', 'return', 'status'];
dataSource: MatTableDataSource<leaveapplication>;
constructor(private leaveApplicationService: LeaveapplicationService) { }
@ViewChild(MatPaginator) paginator: MatPaginator;
@ViewChild(MatSort) sort: MatSort;
ngOnInit() {
this.leaveApplicationService.getLeaveApplications().subscribe(leaveapplications => {
this.leaveApplications = leaveapplications;
this.dataSource = new MatTableDataSource<leaveapplication>(this.leaveApplications);
this.dataSource.paginator = this.paginator;
this.dataSource.sort = this.sort;
console.log(this.dataSource);
});
}
applyFilter(filterValue: string) {
filterValue = filterValue.trim(); // Remove whitespace
filterValue = filterValue.toLowerCase(); // MatTableDataSource defaults to lowercase matches
this.dataSource.filter = filterValue;
}
}
</code></pre>
<p>The leaveapplication interface:</p>
<pre><code>export interface leaveapplication {
id: number;
applicant: string;
manager: string;
startdate: Date;
enddate: Date;
returndate: Date;
leavetype: string;
status: string;
}
</code></pre>
<p>I am getting the dataSource properly in the console:</p>
<p><a href="https://i.stack.imgur.com/8ELb3.png" rel="noreferrer"><img src="https://i.stack.imgur.com/8ELb3.png" alt="enter image description here"></a></p>
<p>But the mat-table return empty cells:</p>
<p><a href="https://i.stack.imgur.com/Qbt1b.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Qbt1b.png" alt="enter image description here"></a></p>
<p>Here is my template:</p>
<pre><code><mat-form-field>
<input matInput (keyup)="applyFilter($event.target.value)" placeholder="Filter">

</mat-table>
<mat-paginator [pageSizeOptions]="[5, 10, 20]" showFirstLastButtons></mat-paginator>
</code></pre>
<p>Why am I not getting the mat-table populated? Is it because of the asynchronous nature of the response?</p>

jquery .prop('disabled', true) not working

<p>I am attempting to toggle <code>disabled = true|false</code> on a <code><input type="text"></code>, using a checkbox. I am able to get the value of the input, but I cannot set the input to disabled.</p>
<p>my jquery/js code</p>
<pre><code><script>
$(function () {

<p>you can see this at <a href="http://jsfiddle.net/78dQE/1/">http://jsfiddle.net/78dQE/1/</a></p>
<p>Any idea why I can get the value of <code>(".roommate")</code> - ie. <code>$(this).prev(".roommate").val()</code><br>
but<br>
<code>$(this).prev(".roommate").disabled = true;</code><br>
OR<br>
<code>$(this).prev(".roommate").prop('disabled', true);</code><br>
will not set <code>(".roommate")</code> to disabled?</p>

yii2 how to run console controller function
|
<p>I'm stuck. I'm trying to run some function from the command shell.
I'm using the HelloController from the basic project.
When I run <code>php yii hello</code> it's working good and the index function is running but if I try to run different function like <code>php yii hello/create</code> I'm getting this error -</p>
<blockquote>
<p>Error: Unknown command.</p>
</blockquote>
<p>I added the create function to this controller.
The strange thing is that when I run <code>php yii</code> I'm seeing the create command.
My controller code </p>
<pre><code>namespace app\commands;
use yii\console\Controller;
use Yii;
class HelloController extends Controller
{
public function actionIndex($message = 'hello world')
{
echo $message . "\n";
}
public function actionCreate($message = 'hello world')
{
echo $message . "\n";
}
}
</code></pre>
<p><strong>UPDATED:</strong>
My Config file is</p>
<pre><code>Yii::setAlias('@tests', dirname(__DIR__) . '/tests');
$params = require(__DIR__ . '/params.php');
$db = require(__DIR__ . '/db.php');

How to use JMS Appender?
|
<p>Inmy research about JMS Appenders I've found <a href="http://activemq.apache.org/how-do-i-use-log4j-jms-appender-with-activemq.html" rel="nofollow">turorial1</a> and <a href="http://code.google.com/p/log4j-jms-sample/wiki/ConfigurationGuide" rel="nofollow">tutorial2</a> . I've tried to follow them, but I couldn't run example program.</p>
<p>Fistly I created file log4j.properties</p>
<pre><code>log4j.rootLogger=INFO, stdout, jms
#
log4j.logger.org.apache.activemq=INFO, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %-5p %c - %m%n
#
log4j.appender.jms=org.apache.log4j.net.JMSAppender
log4j.appender.jms.InitialContextFactoryName=org.apache.activemq.jndi.ActiveMQInitialContextFactory
log4j.appender.jms.ProviderURL=tcp://localhost:61616
log4j.appender.jms.TopicBindingName=logTopic
log4j.appender.jms.TopicConnectionFactoryBindingName=ConnectionFactory
</code></pre>
<p>and jndi.properties</p>
<pre><code>topic.logTopic=logTopic
</code></pre>
<p>Then I added Receiver.java to my project</p>
<pre><code>public class Receiver implements MessageListener {
public Receiver() throws Exception {
ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory("tcp://localhost:61616");
Connection conn = factory.createConnection();
Session sess = conn.createSession(false, Session.AUTO_ACKNOWLEDGE);
conn.start();
MessageConsumer consumer = sess.createConsumer(sess.createTopic("logTopic"));
consumer.setMessageListener(this);
Logger log = Logger.getLogger(Receiver.class);
log.info("Test log");
Thread.sleep(1000);
consumer.close();
sess.close();
conn.close();
System.exit(1);
}
public static void main(String[] args) throws Exception {
new Receiver();
}
@Override
public void onMessage(Message message) {
try {
// receive log event in your consumer
LoggingEvent event = (LoggingEvent)((ActiveMQObjectMessage)message).getObject();
System.out.println("Received log [" + event.getLevel() + "]: "+ event.getMessage());
} catch (Exception e) {
e.printStackTrace();
}
}
}
</code></pre>
<p>I need make Receiver to gather all logs from project, but I cannot even run this simple example. Probably I don't know how to configure it correctly, because I get this output:</p>
<pre><code>log4j:WARN No appenders could be found for logger (org.apache.activemq.transport.WireFormatNegotiator).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
</code></pre>
<p>Did I miss adding some lines in code or some files to classpath? I'm new to log4j.</p>
<p>EDIT:
I set Logger in <code>AspectJ</code> class. But I think that also in <code>Receiver</code> Logger is created and log is sent, so probably it should be done in <code>Receiver</code>, not in other class in my project.</p>
<pre><code>static final Logger logger = Logger.getLogger(ReportingAspect.class);
@Before("setLoggingFile()")
public void setProperties() {
PropertyConfigurator.configure("log4j.properties");
}

Replace Unicode character "�" with a space
|
<p>I'm a doing an massive uploading of information from a .csv file and I need replace this character non ASCII "�" for a normal space, " ".</p>
<p>The character "�" corresponds to "\uFFFD" for C, C++, and Java, which it seems that it is called <a href="https://www.utf8-chartable.de/unicode-utf8-table.pl?start=65280" rel="nofollow noreferrer">REPLACEMENT CHARACTER</a>. There are others, such as spaces type like <a href="https://www.utf8-chartable.de/unicode-utf8-table.pl?start=65279&number=128" rel="nofollow noreferrer">U+FEFF</a>, <a href="https://www.utf8-chartable.de/unicode-utf8-table.pl?start=8287&number=128" rel="nofollow noreferrer">U+205F</a>, <a href="https://www.utf8-chartable.de/unicode-utf8-table.pl?start=8192&number=128" rel="nofollow noreferrer">U+200B</a>, <a href="https://www.utf8-chartable.de/unicode-utf8-table.pl?start=6158&number=128" rel="nofollow noreferrer">U+180E</a>, and <a href="https://www.utf8-chartable.de/unicode-utf8-table.pl?start=8239&number=128" rel="nofollow noreferrer">U+202F</a> in the C# official documentation.</p>
<p>I'm trying do the replace this way:</p>
<pre><code>public string Errors = "";
public void test(){
string textFromCsvCell = "";
string validCharacters = "^[0-9A-Za-z().:%-/ ]+$";
textFromCsvCell = "This is my text from csv file"; //All spaces aren't normal space " "
string cleaned = textFromCsvCell.Replace("\uFFFD", "\"")
if (Regex.IsMatch(cleaned, validCharacters ))
//All code for insert
else
Errors=cleaned;
//print Errors
}
</code></pre>
<p>The test method shows me this text:</p>
<p><strong>"This is my�texto from csv file"</strong></p>
<p>I try some solutions too:</p>
<p><strong>Trying solution 1: Using Trim</strong></p>
<pre><code> Regex.Replace(value.Trim(), @"[^\S\r\n]+", " ");
</code></pre>
<p><strong>Try solution 2: Using Replace</strong></p>
<pre><code> System.Text.RegularExpressions.Regex.Replace(str, @"\s+", " ");
</code></pre>
<p><strong>Try solution 3: Using Trim</strong></p>
<pre><code> String.Trim(new char[]{'\uFEFF', '\u200B'});
</code></pre>
<p><strong>Try solution 4: Add [\S\r\n] to validCharacters</strong></p>
<pre><code> string validCharacters = "^[\S\r\n0-9A-Za-z().:%-/ ]+$";
</code></pre>
<p>Nothing works.</p>
<p>How can I replace it?</p>

Active Index of tabview not getting updated automatically
|
<p>Active Index is not getting updated automatically. ReaD in a few posts that by placing the tabView on a form it works. Or by including <code><p:ajax event="tabChange"/></code> in the tabview it works. But nothing seems to work</p>
<p><strong>xhtml</strong></p>
<p><strong>Sample 1 : automatic updates</strong></p>
<p>
</p>
<pre><code> <p:tabView id="categoryTabView" var="promoArticle" value="#{promotionDetailBean.artDTOs}" activeIndex="#{promotionDetailBean.activeTabIndex}">
<p:tab id="categoriesTab" title="#{promoArticle.categoryName}">
<p:dataTable id="promotionDetail_dataTable" var="articlePromo" value="#{promoArticle.artVO}" selection="#{promotionDetailBean.selectedArt}" rowIndexVar="rowIndex">
<p:column id="select" selectionMode="multiple" />
<p:column id="barCode">
<h:inputText id="barCodeInputTxt" value="#{articlePromo.barCode}"
styleClass="inputTextStyle" onchange="onSuggestedValueChange('categoryTabView',#{promotionDetailBean.activeTabIndex}, 'promotionDetail_dataTable',#{rowIndex},'originalCostInputTxt')" />
</p:column>
</p:dataTable>
</p:tab>
</p:tabView>
</code></pre>
<p><strong>Sample 2: Updating on tabChange event</strong></p>
<pre><code> <h:form id="form">
<p:growl id="growlm" showDetail="true" />
<p:tabView id="categoryTabView" var="promoArticle" value="#{promotionDetailBean.artDTOs}" >
<p:ajax event="tabChange" listener="#{promotionDetailBean.tabChanged}" update=":growlm" />
<p:tab id="categoriesTab" title="#{promoArticle.categoryName}">
<p:dataTable id="promotionDetail_dataTable" var="articlePromo" value="#{promoArticle.artVO}" selection="#{promotionDetailBean.selectedArt}" rowIndexVar="rowIndex">
<p:column id="select" selectionMode="multiple" />
<p:column id="barCode">
<h:inputText id="barCodeInputTxt" value="#{articlePromo.barCode}"
styleClass="inputTextStyle" onchange="onSuggestedValueChange('categoryTabView',#{promotionDetailBean.activeTabIndex}, 'promotionDetail_dataTable',#{rowIndex},'originalCostInputTxt')" />
</p:column>
</p:dataTable>
</p:tab>
</p:tabView>
</code></pre>
<p>I need to identify the cell on "onChange " event. But the activeIndex is always 0, the initialized value. The event doesn't get call.</p>
<p><strong>bean</strong></p>
<pre><code>private Integer activeTabIndex = 0;
public Integer getActiveTabIndex() {
return activeTabIndex;
}
public void setActiveTabIndex(Integer activeTabIndex) {
this.activeTabIndex = activeTabIndex;
}
</code></pre>
<p><strong>bean</strong></p>
<pre><code>public void tabChanged(TabChangeEvent event){
TabView tv = (TabView) event.getComponent();
this.activeTabIndex = tv.getActiveIndex();
}
</code></pre>
<p>But the event is not getting trigerred. Nor getting updated automatically.</p>
<p>What could be the probable issues ?</p>
<p>Thanks,
Shikha</p>

Laravel custom pivot usage (Extends Model or Extends Pivot)
|
<p>I am really stuck using a custom model for my pivot, and don't understand why can we make a custom model for it if we can't use it as a model.
I've seen many answers and articles, and all chose to extend Pivot or Model, but real life usage is never taken into account and never go any further than giving it a "named" class.</p>
<p>Here is an example of what I'm trying to achieve:
My main models:
<strong>Player</strong> model, with <strong><em>players</em></strong> table.
<strong>Game</strong> model, with <strong><em>games</em></strong> table.</p>
<p><strong>Player</strong> and <strong>Game</strong> have a many-to-many relationship, that we can call "<strong>Party</strong>" with a "<strong><em>game_player</em></strong>" table.</p>
<p>Less important for now, I have also a <strong>Score</strong> model that holds the score/turns, a <strong>Party</strong> can have many scores, so <strong><em>scores</em></strong> table has a party_id entry.</p>
<p>So, here are basically my classes (Laravel 5.2):</p>
<p>Player</p>
<pre class="lang-php prettyprint-override"><code>class Player extends Model
{
// The Games this Player is participating to.
public function games() {
return $this->belongsToMany(Game::class)->withPivot('id')->withTimestamps();
}
// The Scores belonging to this Player.
public function parties() {
return $this->hasManyThrough(Score::class, Party::class);
}
// The Custom Pivot (Party) creation for this Player.
public function newPivot(Model $parent, array $attributes, $table, $exists) {
if ($parent instanceof Game) {
return new Party($parent, $attributes, $table, $exists);
}
return parent::newPivot($parent, $attributes, $table, $exists);
}
}
</code></pre>
<p>Game</p>
<pre class="lang-php prettyprint-override"><code>class Game extends Model
{
// The Players participating into this Game.
public function players() {
return $this->belongsToMany(Player::class)->withPivot('id')->withTimestamps();
}
// The Scores belonging to this Party.
public function parties() {
return $this->hasManyThrough(Score::class, Party::class);
}
// The Custom Pivot (Party) creation for this Game.
public function newPivot(Model $parent, array $attributes, $table, $exists) {
if ($parent instanceof Player) {
return new Party($parent, $attributes, $table, $exists);
}
return parent::newPivot($parent, $attributes, $table, $exists);
}
}
</code></pre>
<p>Party</p>
<pre class="lang-php prettyprint-override"><code>class Party extends Pivot
{
protected $table = 'game_player';
// The Player this Party belongs to.
public function player() {
return $this->belongsTo(Player::class);
}
// The Game this Party belongs to.
public function event() {
return $this->belongsTo(Game::class);
}
// The Scores belonging to this Party.
public function scores()
{
return $this->hasMany(Score::class);
}
}
</code></pre>
<p>Score</p>
<pre class="lang-php prettyprint-override"><code>class Score extends Model
{
// The Party this Score belongs to (has "party_id" column).
public function party() {
return $this->belongsTo(Party::class);
}
}
</code></pre>
<p>Now, I have two different sets of problems that appear depending on if I extend Model or Pivot on Party:</p>
<p>1) When Party extends Pivot:</p>
<ul>
<li>Can't do something like <strong>Party::count()</strong>, anything that works with models.</li>
<li>Can't do something like <strong>Party::where("player_id", $player->id)</strong> and so on ... Basically I want the party to have a scores/turns table attached to it and to do so I need to select the pivot model.</li>
<li>Can't do something like $events->player->first()->scores() nor event $events->player->first()->pivot->scores(), it breaks with the following:</li>
</ul>
<blockquote>
<p>PHP error: Argument 1 passed to Illuminate\Database\Eloquent\Relations\Pivot::__construct() must be an instance of Illuminate\Database\Eloquent\Model</p>
</blockquote>
<p>2) When Party extends Model:</p>
<ul>
<li>Can do trivial things such as Party::count(), Party::where("Game_id", $game->id)</li>
<li>Lose all pivot functions, so can't do $game->players, not even $game->players() work: $game->players()->count() is correct, but $game->players()->first() or $game->players->first() will break with the following:</li>
</ul>
<blockquote>
<p>PHP error: Argument 1 passed to Illuminate\Database\Eloquent\Model::__construct() must be of the type array, object given</p>
</blockquote>
<p>Question:</p>
<p>How to correctly use the custom pivot model when instantiating them is different?</p>
<p>I hope to achieve the following:</p>
<ul>
<li>Do the normal $events->players->attach($player)</li>
<li>Be able to attach a score like $score->party_id = $events->players->find($x)->pivot->id (or any other way via a scope for example)</li>
<li>Be able to count all parties being played, or the ones on one specific game or by a specific player (something like Party::count(), $player->parties->count() etc)</li>
</ul>
<p>Thank you.</p>

Angular2 Animation on Load and Page Transition
|
<p>Currently trying to implement some animations into my Angular2 site using ng2's built in <code>animations</code> component. So far I've been working through the Angular 2 <code>Developer Guide - Animations</code> provided in the documentation. With that though I've run into a few questions I was hoping the SO community might be able to assist in. My first question/problem I seem to be having is that the animation (from what I can tell) doesn't run on page load. It seems to run perfectly fine if I switch to a view then back to the view with the animation. This is the code I'm currently using for the animation in question (I can provide the whole component if desired):</p>
<pre><code>animations: [
trigger('kissState', [
state('in', style({opacity: 1})),
transition('void => *', [
style({opacity: 0}),
animate('250ms ease-in-out')
]),
transition('* => void', [
animate('250ms ease-in-out', style({opacity: 0}))
])
])
]
</code></pre>
<p>I was under the impression that the <code>void => *</code> would set my DOM element to <code>opacity:0</code> and once it entered <code>in</code> to the view it would be <code>opacity:1</code>. Another problem I seem to be having is that my navigations don't seem to be working on mobile. I haven't actually moved them to my server yet but developing locally and looking on my mobile device via node <code>localtunnel</code> there doesn't seem to be any animations. This could be because the strange way <code>localtunnel</code> operates so I'm not too terribly concerned about that until I can truly test it on an actual server. Here's the other animation that in particular is when I noticed it wasn't working on my mobile device: </p>
<pre><code>animations: [
trigger('offScreenMenu', [
state('inactive', style({
opacity: 0,
zIndex: -10
})),
state('active', style({
backgroundColor: 'rgba(255, 255, 255, 0.8)',
zIndex: 10
})),
transition('inactive => active', animate('250ms ease-in')),
transition('active => inactive', animate('250ms ease-out'))
])
]
</code></pre>
<p>One last problem I've been having which is a known issue by the Angular2 team is animations on router view change. There's currently a SO <a href="https://stackoverflow.com/questions/37904860/angular-2-animate-no-visible-effect-of-the-void-transition-when-changin">question</a> that addresses this and a ticket on the Angular2 repo (mentioned in the comment by Günter Zöchbauer in the SO question). With that, I was curious if there were any present workarounds? Through some brief research it looked like there may at one time have been implemented a <code>ng-enter</code> and <code>ng-leave</code> one could use within their css for this, but from what I can tell these have been phased out. Still need to do a little more research so I could be wrong about that. </p>
<p>Thanks in advance for any help!</p>
<p>UPDATE(7.7.16): Alright so I decided to come back around to it and after messing with the timing of the page load animation it does appear to be working. Though I have to do a roughly a <code>1000ms</code> animation for it to be noticed. Which brings me to the questions (or more thought) that I believe the animation starts to execute before the DOM has fully loaded. Which would seem a bit strange.
Still working on the mobile animation situation. Looking like I'll be filing an issue on the Github repo at the moment as I've messed with it a fair bit and can't seem to get it to work. Also there doesn't seem to be any mention of mobile animations not working for NG2.</p>
<p>UPDATE(7.13.16): Looks like the Angular2 team has made a few fixes slated to release with RC5 that should address my above concerns. Going to answer my own question and close.</p>

Problems using foreach parallelization
|
<p>I'm trying to compare parallelization options. Specifically, I'm comparing the standard <code>SNOW</code> and <code>mulitcore</code> implementations to those using <code>doSNOW</code> or <code>doMC</code> and <code>foreach</code>. As a sample problem, I'm illustrating the central limit theorem by computing the means of samples drawn from a standard normal distribution many times. Here's the standard code:</p>
<pre><code>CltSim <- function(nSims=1000, size=100, mu=0, sigma=1){
sapply(1:nSims, function(x){
mean(rnorm(n=size, mean=mu, sd=sigma))
})
}
</code></pre>
<p>Here's the <code>SNOW</code> implementation:</p>
<pre><code>library(snow)
cl <- makeCluster(2)
ParCltSim <- function(cluster, nSims=1000, size=100, mu=0, sigma=1){
parSapply(cluster, 1:nSims, function(x){
mean(rnorm(n=size, mean=mu, sd=sigma))
})
}
</code></pre>
<p>Next, the <code>doSNOW</code> method:</p>
<pre><code>library(foreach)
library(doSNOW)
registerDoSNOW(cl)
FECltSim <- function(nSims=1000, size=100, mu=0, sigma=1) {
x <- numeric(nSims)
foreach(i=1:nSims, .combine=cbind) %dopar% {
x[i] <- mean(rnorm(n=size, mean=mu, sd=sigma))
}
}
</code></pre>
<p>I get the following results:</p>
<pre><code>> system.time(CltSim(nSims=10000, size=100))
user system elapsed
0.476 0.008 0.484
> system.time(ParCltSim(cluster=cl, nSims=10000, size=100))
user system elapsed
0.028 0.004 0.375
> system.time(FECltSim(nSims=10000, size=100))
user system elapsed
8.865 0.408 11.309
</code></pre>
<p>The <code>SNOW</code> implementation shaves off about 23% of computing time relative to an unparallelized run (time savings get bigger as the number of simulations increase, as we would expect). The <code>foreach</code> attempt actually <strong>increases</strong> run time by a factor of 20. Additionally, if I change <code>%dopar%</code> to <code>%do%</code> and check the unparallelized version of the loop, it takes over 7 seconds.</p>
<p>Additionally, we can consider the <code>multicore</code> package. The simulation written for <code>multicore</code> is</p>
<pre><code>library(multicore)
MCCltSim <- function(nSims=1000, size=100, mu=0, sigma=1){
unlist(mclapply(1:nSims, function(x){
mean(rnorm(n=size, mean=mu, sd=sigma))
}))
}
</code></pre>
<p>We get an even better speed improvement than <code>SNOW</code>:</p>
<pre><code>> system.time(MCCltSim(nSims=10000, size=100))
user system elapsed
0.924 0.032 0.307
</code></pre>
<p>Starting a new R session, we can attempt the <code>foreach</code> implementation using <code>doMC</code> instead of <code>doSNOW</code>, calling</p>
<pre><code>library(doMC)
registerDoMC()
</code></pre>
<p>then running <code>FECltSim()</code> as above, still finding</p>
<pre><code>> system.time(FECltSim(nSims=10000, size=100))
user system elapsed
6.800 0.024 6.887
</code></pre>
<p>This is "only" a 14-fold increase over the non-parallelized runtime.</p>
<p>Conclusion: My <code>foreach</code> code is not running efficiently under either <code>doSNOW</code> or <code>doMC</code>. Any idea why?</p>
<p>Thanks,
Charlie</p>

WatiN hangs on "about:blank" for multiple concurrent IE8 instances
|
<p>I’m trying to test several web sites using the latest version of WatiN.</p>
<p>If a try to run several tests simultaneously, WatiN will eventually throw an exception “<strong>Timeout while Internet Explorer busy</strong>”. This occurs because Internet Explorer eventually gets “stuck” trying to connect to “<strong>about:blank</strong>”.</p>
<p>Runtime environment:</p>
<ul>
<li>Windows 7 Professional</li>
<li>Internet Explorer 8 (Version 8.0.7600.16385)</li>
<li>WatiN (Version 2.1.0.1196)</li>
</ul>
<p>I have distilled the problem to the following bare-bones c# console program. To recreate the problem, create a new c# .NET 3.5 console program from Visual Studio, add a reference to WatiN.Core.dll, compile, then run. After about 10 seconds on my machine, IE hangs on "about:blank", and eventually WatiN times out and generates an exception.</p>
<p>Increasing the WatiN timeouts only delays the problem.</p>
<p>Has anyone else seen this problem? Can you reproduce the problem using my example program? Any solutions?</p>
<p><strong>[Code]</strong></p>
<pre><code>namespace IEBugUsingWatiN
{
using System;
using System.Collections.Generic;
using System.Threading;
using WatiN.Core;
class Program
{
const int MAX_THREADS = 7;

{
Console.WriteLine( "Initializing WatiN." );
var watinSettings = WatiN.Core.Settings.Instance;
watinSettings.AutoCloseDialogs = false;
watinSettings.AutoMoveMousePointerToTopLeft = false;
watinSettings.AutoStartDialogWatcher = false;

<p><strong>[Update]</strong></p>
<p>Microsoft has confirmed that this is a known bug. To make a long story short, IE (specifically, <strong>wininet.dll</strong>) leaks connections under certain circumstances. The only suggested workaround is to explicitly kill all Internet Explorer process instances after running a Test. A "fix" is not likely since this has been an issue for YEARS, and they are afraid of breaking compatibility with existing applications.</p>
<p>FYI, here is what Microsoft has to say:</p>
<blockquote>
<p>The best workaround would probably to
kill and restart IE at some interval
during your test run automation. You
can restart IE at some regular
interval or have some kind of
detection logic in your code. When
you get into this situation IE won’t
be able to make any request out so I
would expect the application to
receive a <strong>BeforeNavigate</strong> event (if
you sink this event) set up a timer
and by the time the timer fires check
to see if you ever get a
<strong>DocumentComplete</strong> event for the URL (which you probably won’t). This is a
good indication that you run into the
problem so you can proceed to kill and
restart the IE process at this point.</p>
<p>...this approach is not addressing the
root cause of wininet connection loss
but at the same time there aren’t any
practical approach within your control
to do this. Just to provide some
perspective on how you get into this
situation…</p>
<p>Whenever there are ActiveX components
(such as msxml making an AJAX request)
making an HTTP request and the Tab
window hosting that component is
closed before the response is
received, there is a chance IE will
lose that wininet connection if the
ActiveX does not abort the call. This
is exactly what happened in the hertz
scenario. The page has script running
to issue an AJAX request. IE window
is then closed before the response
comes back. Upon part of tearing down
the page, IE calls into the ActiveX
(MSXML in this case) to notify the
control upon shutting down. The
control can then abort that connection
upon being destroyed. MSXML does not
abort the connection here leading to
the leak. The issue is deeply rooted
in IE’s design architecture and how it
interacts with 3rd party components.
Because of this you will most likely
encounter this issue on web sites that
have AJAX requests. Over the years
there are multiple bugs opened against
this issue but all those bugs were
rejected due to high application
compat risk. Part of the difficulty
in providing a fix is that IE does not
always know that the ActiveX is the
one making a connection.</p>
<p>Wininet does not expose any mechanism
for a 3rd party control to reset or
clean up the wininet connection loss.
By default IE6/7 has 2 connections per
server while IE8 has 6 so this
behavior is probably less visible in
IE8. There is a registry key
documented here
<a href="http://support.microsoft.com/kb/183110" rel="nofollow">http://support.microsoft.com/kb/183110</a>
you can try to increase the number of
available connections. However this
is only delaying the problem. This is
why I mentioned the only supportable
way to reset the wininet state is to
restart the IE process.</p>

Typescript error when using React useContext and useReducer

Changes using Winspool.drv in Windows 7 64 bit from Windows XP 32 bit
|
<p>I have some C# code (VS2010;fx2) which is used to carry out printer functions. This code works fine in Windows XP environment. Changing to Windows 7, it no longer works correctly.</p>
<p>The first different behaviour is that the GetPrinterNames() method now only returns local printers. As you can see, the flags are set to include NETWORK printers also. I've tried different flags, but with no success.</p>
<p>Is there a different library I should be referencing in Windows 7 / 64 bit version?</p>

<p><strong>QUESTION:</strong></p>
<p>Using PHP's SoapClient, how do I:</p>
<ol>
<li>init SoapClient and load the WSDL file (which sits in my server)?</li>
<li>Set the header?</li>
<li>Send the SOAP request?</li>
<li>And finally, get a SOAP response back and extract the values of <strong>Output1, Output2, and Output3</strong> into variables?</li>
</ol>
<p>I've browse previous StackOverflow questions regarding SOAP and WSSE headers, but could not find the answer.</p>
<p>Thanks very much in advance for your time and your expert help!</p>
<p>PS: I can accomplish the above using cURL. But I want to know how to do it using SoapClient. Thanks again!</p>

Is there a benefit in using old style `object` instead of `class` in Delphi?
|
<p>In Delphi <strong>sane</strong> people use a <code>class</code> to define objects.<br>
In Turbo Pascal for Windows we used <code>object</code> and today you can still use <code>object</code> to create an object. </p>
<p>The difference is that a <code>object</code> lives on the stack and a <code>class</code> lives on the heap.<br>
And of course the <code>object</code> is depreciated. </p>
<p><kbd>Putting all that aside:</kbd></p>
<p><strong>is there a benefit to be had, speed wise by using <code>object</code> instead of class?</strong></p>
<p><em>I know that <code>object</code> is broken in Delphi 2009, but I've got a special use case<sup>1)</sup> where speed matters and I'm trying to find if using <code>object</code> will make my thing faster without making it buggy</em><br>
This code base is in Delphi 7, but I may port it to Delphi 2007, haven't decided yet.</p>

<p><strong>Long comment</strong><br>
Thanks all for pointing me in the right direction.</p>
<p>Let me explain a bit more. I'm trying to do a faster implementation of <strong><a href="http://en.wikipedia.org/wiki/Hashlife" rel="noreferrer">hashlife</a></strong>, <a href="http://drdobbs.com/high-performance-computing/184406478" rel="noreferrer">see also here</a> or <a href="http://dotat.at/prog/life/hashlife.c" rel="noreferrer">here for simple sourcecode</a></p>
<p>The current record holder is <a href="http://golly.sourceforge.net/" rel="noreferrer">golly</a>, but golly uses a straight translation of Bill Gospher original lisp code (which is brilliant as an algorithm, but not optimized at the micro level at all). Hashlife enables you to calculate a generation in O(log(n)) time.</p>
<p>It does this by using a space/time trade off. And for this reason hashlife needs a lot of memory, gigabytes are not unheard of. In return you can calculate generation 2^128 (340282366920938463463374607431770000000) using generation 2^127 (170141183460469231731687303715880000000) in o(1) time. </p>
<p>Because hashlife needs to compute hashes for all sub-patterns that occur in a larger pattern, allocation of objects needs to be fast.</p>
<p>Here's the solution I've settled upon:</p>
<p><strong>Allocation optimization</strong><br>
I allocate one big block of physical memory (user settable) lets say 512MB. Inside this blob I allocate what I call <strong>cheese stacks</strong>. This is a normal stack where I push and pop, but a pop can also be from the middle of the stack. If that happens I mark it on the <code>free</code> list (this is a normal stack). When pushing I check the <code>free</code> list first if nothing is free I push as normal. I'll be using records as advised it looks like the solution with the least amount of overhead. </p>
<p>Because of the way hashlife works, very little <code>pop</code>ping takes place and a lot of <code>push</code>es. I keep separate stacks for structures of different sizes, making sure to keep memory access aligned on 4/8/16 byte boundaries. </p>
<p><strong>Other optimizations</strong> </p>
<ul>
<li>recursion removal </li>
<li>cache optimization</li>
<li>use of <code>inline</code></li>
<li>precalculation of hashes (akin to rainbow tables)</li>
<li>detection of pathological cases and use of fall-back algorithm</li>
<li>use of GPU</li>
</ul>
