showing download progress while downloading a file using PHP and jquery
|
<p>I am developing a download manager using PHP and jquery.</p>
<p>Requested a script that will download a file and also show the download progress.</p>
<p>I tried the following, but it not works</p>
<p>Jquery</p>
<pre><code>function downloadFile(){
var fileNameDownloading ="somefile.mp3"
var oReq = new XMLHttpRequest();
oReq.addEventListener("progress", updateProgress, false);
var params = "filename="+fileNameDownloading;
oReq.open("GET", "scripts/download.php?"+params, true);
oReq.responseType = "blob";//blob arraybuffer
function updateProgress (e) {
console.log(e.loaded/e.total);
}
oReq.send();
}
</code></pre>
<p>PHP</p>
<pre><code><?php
$file = $_GET['filename'];
$fileSize = get_size($file);
$packetSize = 262144;//2000
if($packetSize > $fileSize){
$packetSize = $fileSize;
}
download($file,$packetSize);
function download($file,$chunks){
set_time_limit(0);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-disposition: attachment; filename='.basename($file));
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Expires: 0');
header('Pragma: public');
$size = get_size($file);
header('Content-Length: '.$size);
$i = 0;
while($i<=$size){
//Output the chunk
get_chunk($file,(($i==0)?$i:$i+1),((($i+$chunks)>$size)?$size:$i+$chunks));
$i = ($i+$chunks);
}
}
//Callback function for CURLOPT_WRITEFUNCTION, This is what prints the chunk
function chunk($ch, $str) {
print($str);
return strlen($str);
}
//Function to get a range of bytes from the remote file
function get_chunk($file,$start,$end){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $file);
curl_setopt($ch, CURLOPT_RANGE, $start.'-'.$end);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
curl_setopt($ch, CURLOPT_WRITEFUNCTION, 'chunk');
$result = curl_exec($ch);
curl_close($ch);
}
//Get total size of file
function get_size($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_exec($ch);
$size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
return intval($size);
}
?>

<p>Looking for a suggestion, how we can download a file and also show download progress using PHP and javascript. Thanks</p>

PRESTASHOP NGINX + REWRITE RULES

<p>I've being searching for a good solution for this combination and after following these:</p>

android - How to mux audio file and video file?

<p>i have a 3gp file that is recorded from the microphone and a mp4 video file.
i want to mux audio file and video file in to a mp4 file and save it.
i searched a lot but didn't find any thing helpful for using MediaMuxer api of android.

<p>UPDATE : this is my method that mux two files , i have an Exception in it.
and the reason is that the destination mp4 file doesn't have any track!

Redraw/refresh Itemizedoverlay? (android/google maps api)
|
<p>I am making a GPS tracker using google maps API and displaying the users current position on a map using ItemizedOverylay. As the users position changes regularly, I've set up a CountDownTimer to delete the current Itemizedoverlay and add a new one at the new position every 5 seconds (there is no way of changing an itemizedOverlay's position) but the screen isn't drawing the new positions unless i physically touch the screen! Here is the code for my itemized overlay:</p>
<pre><code>import java.util.ArrayList;
import java.util.List;
import android.app.AlertDialog;
import android.content.Context;
import android.graphics.drawable.Drawable;
import android.widget.Toast;
import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.OverlayItem;
public class HelloItemizedOverlay extends ItemizedOverlay{
private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
Context mContext;
public HelloItemizedOverlay(Drawable defaultMarker) {
/*This passes the defaultMarker up to the default constructor
* to bound its coordinates and then initialize mContext with the given Context.*/
super(boundCenterBottom(defaultMarker));
}
public HelloItemizedOverlay(Drawable defaultMarker, Context context) {
/*This passes the defaultMarker up to the default constructor
* to bound its coordinates and then initialize mContext with the given Context.*/
super(boundCenterBottom(defaultMarker));
mContext = context;
}
@Override
protected boolean onTap(int index) {
/*This uses the member android.content.Context to create
* a new AlertDialog.Builder and uses the tapped OverlayItem's title
* and snippet for the dialog's title and message text. (You'll see the
* OverlayItem title and snippet defined when you create it below.)*/
OverlayItem item = mOverlays.get(index);
AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
dialog.setTitle(item.getTitle());
dialog.setMessage(item.getSnippet());
dialog.show();
return true;
}
public void addOverlay(OverlayItem overlay) {
mOverlays.add(overlay);
/*Each time you add a new OverlayItem to the ArrayList, you must
* call populate() for the ItemizedOverlay, which will read each
* of the OverlayItems and prepare them to be drawn.*/
populate();
}
public void addOverlayList(List<OverlayItem> overlayitems) {
Object temp[] = overlayitems.toArray();
try{
for(int i = 0;i<temp.length;i++)
{
mOverlays.add((OverlayItem)temp[i]);
}
}catch(Error e)
{
Toast.makeText(mContext, "Something happened when adding the overlays:"+e.getMessage() ,
Toast.LENGTH_LONG).show();
}
populate();
}
public void removeOverlayList(List<OverlayItem> overlayitems) {

@Override
public int size() {
/*You must also override the size() method to return the current
* number of items in the ArrayList:*/
return mOverlays.size();
}
}
</code></pre>
<p>Does anyone know if there is a method or something I can call to force a redraw/refresh when I put the new items in?</p>
<p>EDIT: Here is a snippet of the MapsActivity:</p>
<pre><code>public class HelloGoogleMaps extends MapActivity {

Want to add spacing between buttons
|
<p>I have a simple task to add space between buttons in a dialog box like in the example code below obtained from <a href="http://bootboxjs.com/examples.html" rel="noreferrer">http://bootboxjs.com/examples.html</a>. Just imagine that there is more than 1 button is this example. Like save, delete, cancel, confirm.</p>
<pre><code>bootbox.dialog({
title: "This is a form in a modal.",
message: '<div class="row"> ' +
'<div class="col-md-12"> ' +
'<form class="form-horizontal"> ' +
'<div class="form-group"> ' +
'<label class="col-md-4 control-label" for="name">Name</label> ' +
'<div class="col-md-4"> ' +
'<input id="name" name="name" type="text" placeholder="Your name" class="form-control input-md"> ' +
'<span class="help-block">Here goes your name</span> </div> ' +
'</div> ' +
'<div class="form-group"> ' +
'<label class="col-md-4 control-label" for="awesomeness">How awesome is this?</label> ' +
'<div class="col-md-4"> <div class="radio"> <label for="awesomeness-0"> ' +
'<input type="radio" name="awesomeness" id="awesomeness-0" value="Really awesome" checked="checked"> ' +
'Really awesome </label> ' +
'</div><div class="radio"> <label for="awesomeness-1"> ' +
'<input type="radio" name="awesomeness" id="awesomeness-1" value="Super awesome"> Super awesome </label> ' +
'</div> ' +
'</div> </div>' +
'</form> </div> </div>',
buttons: {
success: {
label: "Save",
className: "btn-success",
callback: function () {
var name = $('#name').val();
var answer = $("input[name='awesomeness']:checked").val()
Example.show("Hello " + name + ". You've chosen <b>" + answer + "</b>");
}
}
}
}
);
</code></pre>
<p>I would like to know how to increase the spacing between the buttons so that they are placed more far apart and look spacious and the UI of the dialog box is more beautiful. I am not so good at these stuff. I have searched a lot. Please help me. Your help will be much appreciated. Thank you very much.</p>
<p>Please give some code and live example if possible. Thank you again.</p>

Deactivate a Gem - "you have already activated rake 0.9.3.beta.1, but my Gemfile requires rake 0.9.2"
|
<p>I'm trying to run a migration but I keep getting the error message that is:</p>
<pre><code>rake aborted! Undefined method prerequisite for nil:NilClass.
</code></pre>
<p>It seems that somehow I activated a gem called <code>rake 0.9.3.beta.1</code> - however I have since changed the gem <code>bundle install</code> and run <code>bundle show</code> rake and it shows that <code>rake 0.9.2</code> is installed. I'm using Git for the first time so I thought that maybe it had something to do with the application still using the beta version of rake - but I've done a push and it shows that the gemfile has been updated.</p>
<p>and when I look down into the gem libraries I can only see the <code>rake 0.9.2</code> version. Where should I be looking?</p>
<p>I also have a Rails:Railtie deprecated warning - but I'm thinking that this doesn't have anything to do with my migration problems. Its telling me to use config.app_generators in config/application.rb instead of Railtie - but i can't see that in the file. </p>
<p>This is the Config/application.rb file </p>
<pre><code>require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
Bundler.require *Rails.groups(:assets) if defined?(Bundler)
module CrowdshareApp
class Application < Rails::Application
config.encoding = "utf-8"
config.filter_parameters += [:password]
config.assets.enabled = true
end
end
</code></pre>
<p>My Gemfile looks like this:</p>
<pre><code>source 'http://rubygems.org'
gem 'rails', '3.1.0.rc5'
gem 'sqlite3'

gem 'sass-rails', "~> 3.1.0.rc"

How are date and datetime supposed to be serialized SOAP (xml) messages
|
<p>We are working on a building a java client with a third party SOAP Webservice, that is I have not access or control off server side code. We are just provided with the WSDL description file of the service. We are using Axis 1 (version 1.4 ). </p>
<p>We have run into following issue related to date vs datetime serialization and deserialization. The said wsdl defines two types DateTime and DateRange</p>
<pre><code><xs:element minOccurs="0" name="DateTime" type="xs:dateTime"/>
<xs:element minOccurs="0" name="DateRange">
<xs:complexType>
<xs:sequence>
<xs:element name="Start" type="xs:date"/>
<xs:element name="End" type="xs:date"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</code></pre>
<p>Where xs prefix denotes XML Schema, that is following is present </p>
<pre><code>xmlns:xs="http://www.w3.org/2001/XMLSchema"
</code></pre>
<p>The axis wsdl2java generates Java Objects whre datetime field is type to Calendar, and start, end fields are typed to java.util.Date</p>
<p>When serialization happens the start and end fields are serialized to yyyy-mm-dd format , for example 2014-02-01
But when the actual call is made to server side we recieve following response</p>
<pre><code><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<SOAP-ENV:Fault>
<faultcode>SOAP-ENV:Server</faultcode>
<faultstring xml:lang="en">JiBX unmarshalling exception; nested exception is org.jibx.runtime.JiBXException: Missing 'T' separator in dateTime</faultstring>
</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
</code></pre>
<p>We used SOAP UI to build the request xml payload directly and observed if we pass just the date portion in start and end fields we get exact same response, while if we pass those two fields with time portion like a dateTime field it works, gives no fault message.</p>
<p>This when taken together with what I could gleam from XMLSchema documentation for
<a href="http://www.w3.org/TR/xmlschema-2/#date" rel="nofollow"> xs:date </a> and <a href="http://www.w3.org/TR/xmlschema-2/#dateTime" rel="nofollow">xs:dateTime</a> , in particular lexical and canonical representation section, seems to imply that</p>
<ol>
<li><p>Axis based serialization of start and end field to just yyyy-mm-dd and ignoring the time portion is correct. And client side code generated conforms to WSDL provided to us.</p></li>
<li><p>Server side code does not conform to WSDL provided to us, it expects a dateTime field rather than a date field.</p></li>
<li><p>Since date and dateTime field are required to be serialized in different formats by the schema definition. The result it failure at server side when it attempts to de-serialize
the message </p></li>
</ol>
<p>To validate our hypothesis 1. we used Python's ZSI library to generate python stub and resulting xml from it.<br>
Even that serializes start and end in yyyy-mm-dd format , with an additional 'Z' at the end.
This again fails to get deserialized at server side, even though this serialization format conforms to xs:date as defined by XML Schema</p>
<pre><code><ns1:Start>2014-02-05Z</ns1:Start>
</code></pre>
<p>Can somebody confirm if hypothesis formed by us, based on observed behaviour, documentation and experiment with Python's ZSI is correct. Or if we are missing some detail</p>

Puppet: Passing parameters through classes
|
<p>This is a follow on to my earlier question about <a href="https://stackoverflow.com/questions/21151902/puppet-stopping-service-on-individual-nodes/21153390">parameterized classes</a>. Following on that example a little further, I want to be able to pass running or stopped into the service, but when I add the service to a box, I don't use "include poodle::service", I use "include poodle" which does all of the other stuff Poodle requires to be installed.</p>
<p>So, can I pass the variable along to the service class like this:</p>
<pre><code># SITE.PP
node 'tweedle.example.com' {
include basicstuff
include poodle
}
node 'beetle.example.com' {
include basicstuff
class { 'poodle':
$ensure => 'stopped'
}
}
## POODLE MODULE, manifests/init.pp
class poodle ( $ensure = 'running' ) {
class {'poodle::install': }
class {'poodle::config': }
class {'poodle::service':
ensure => $ensure
}
Class ['poodle::install'] -> Class ['poodle::config'] ~> Class ['poodle::service']
}
...
class poodle::service ( $ensure ) {
service {'poodle':
ensure => $ensure,
enable => true,
restart => "/etc/init.d/poodle stop && sleep 5 && /etc/init.d/poodle start",
subscribe => File['/opt/poodle/poodle.py'],
}
}
</code></pre>
<p>Or should I put the parameter directly on the service class and the explicitly call both the Poodle class and Poodle's service class like this:</p>
<pre><code># SITE.PP
node 'tweedle.example.com' {
include basicstuff
include poodle
}
node 'beetle.example.com' {
include basicstuff
include poodle
class { 'poodle::service':
$ensure => 'stopped'
}
}
## POODLE MODULE, manifests/init.pp
class poodle {
class {'poodle::install': }
class {'poodle::config': }
class {'poodle::service':
ensure => $ensure
}
Class ['poodle::install'] -> Class ['poodle::config'] ~> Class ['poodle::service']
}
...
class poodle::service ( $ensure = 'running') {
service {'poodle':
ensure => $ensure,
enable => true,
restart => "/etc/init.d/poodle stop && sleep 5 && /etc/init.d/poodle start",
subscribe => File['/opt/poodle/poodle.py'],
}
}
</code></pre>
<p>Or is adding the parameter to the service class and including ONLY that enough, because the service class has dependencies, like this:</p>
<pre><code># SITE.PP
node 'tweedle.example.com' {
include basicstuff
include poodle
}
node 'beetle.example.com' {
include basicstuff
class { 'poodle::service':
$ensure => 'stopped'
}
}
## POODLE MODULE, manifests/init.pp
class poodle {
class {'poodle::install': }
class {'poodle::config': }
class {'poodle::service':
ensure => $ensure
}
Class ['poodle::install'] -> Class ['poodle::config'] ~> Class ['poodle::service']
}
...
class poodle::service ( $ensure = 'running') {
service {'poodle':
ensure => $ensure,
enable => true,
restart => "/etc/init.d/poodle stop && sleep 5 && /etc/init.d/poodle start",
subscribe => File['/opt/poodle/poodle.py'],
}
}
</code></pre>
<p>What is the right course and best practice here? Thanks in advance!</p>

use Kestrel in .NET Core worker project
|
<p>I created a new .NET Core worker project with the template provided by Visual Studio. I want to listen for incoming TCP messages and HTTP requests. I'm following <a href="https://github.com/davidfowl/MultiProtocolAspNetCore" rel="nofollow noreferrer">David Fowler's "Multi-protocol Server with ASP.NET Core and Kestrel" repository</a> on how to setup Kestrel.</p>
<p>AFAIK all I have to do is to install the <strong>Microsoft.AspNetCore.Hosting</strong> package to get access to the <code>UseKestrel</code> method.</p>
<p>In the <strong>Program.cs</strong> file I'm currently doing this</p>
<pre><code>public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureServices((hostContext, services) =>
{
services.AddHostedService<Worker>();
});
}
</code></pre>
<p>Unfortunately I can't append <code>UseKestrel</code> to the <code>ConfigureServices</code> method. I think this is because I'm working with the <code>IHostBuilder</code> interface instead of the <code>IWebHostBuilder</code> interface.</p>
<p><em>This project should not be a Web API project, it should remain as a Worker project.</em></p>
<p>Any ideas how to configure Kestrel for this?</p>
<hr />
<p>I tried to change the code to the code from the sample repository</p>
<pre><code>using System.Net;
using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Connections;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.DependencyInjection;
namespace Service
{
public class Program
{
public static void Main(string[] args)
{
CreateWebHostBuilder(args).Build().Run();
}
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureServices(services =>
{
// ...
})
.UseKestrel(options =>
{
// ...
});
}
}
</code></pre>
<p>When doing so it is still not able to resolve <code>WebHost</code> and comes up with these errors</p>
<ul>
<li>
<blockquote>
<p>There is no argument given that corresponds to the required formal parameter 'middleware' of 'ConnectionBuilderExtensions.Run(IConnectionBuilder, Func<ConnectionContext, Task>)'</p>
</blockquote>
</li>
<li>
<blockquote>
<p>The name 'WebHost' does not exist in the current context</p>
</blockquote>
</li>
</ul>
<p>I think this happens because the worker project does not use a Web SDK.</p>

Converting a string to LPCWSTR for CreateFile() to address a serial port
|
<p>I seem to be having a bit of a TEXT / UNICODE problem when using the windows CreateFile function for addressing a serial port. Can someone please help point out my error?</p>
<p>I'm writing a Win32 console application in VC++ using VS 2008.</p>
<p>I can create a handle to address the serial port like this:</p>
<pre><code>#include <iostream>
#include <windows.h>
#include <string>
int main()
{
HANDLE hSerial;
hSerial = CreateFile( L"\\\\.\\COM20",
GENERIC_READ | GENERIC_WRITE,
0,
0,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
0);`
return 0;
}
</code></pre>
<p>That works just fine (the <code>\\\\.\\</code> bit is required for comports greater than COM9 and works for those up to COM9 also). The problem is that my comport will not always be COM20, so I'd like to have the user specify what it is.</p>
<p>Here are some things I've tried:</p>
<pre><code>#include <iostream>
#include <windows.h>
#include <string>
int main()
{
std::string comNum;
std::cout << "\n\nEnter the port (ex: COM20): ";
std::cin >> comNum;
std::string comPrefix = "\\\\.\\";
std::string comID = comPrefix+comNum;
HANDLE hSerial;
hSerial = CreateFile( comID,
GENERIC_READ | GENERIC_WRITE,
0,
0,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
0);`
return 0;
}
</code></pre>
<p>This does not compile and returns the error: <strong>error C2664: 'CreateFileW' : cannot convert parameter 1 from 'std::string' to 'LPCWSTR'</strong></p>
<p>I thought maybe specifying CreateFileA would work then, but that gave basically the same error.</p>
<p>I also tried :</p>
<pre><code>/*
everything else the same
*/
hSerial = CreateFile( TEXT(comID),
GENERIC_READ | GENERIC_WRITE,
0,
0,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
0);`
</code></pre>
<p>which also does not compile and returns: <strong>error C2065: 'LcomID' : undeclared identifier</strong></p>
<p>I am not much of an expert but I have been working on this for a while now. Can someone tell me how to replace <code>L"\\\\.\\COM20"</code> in such a way that the user can specify the comport and so that CreateFile will still work? Thanks!</p>

django errno 104 Connection reset by peer
|
<p>I am trying to run my django server on an Ubuntu instance on AWS EC2. I am using gunicorn to run the server like this :</p>
<p><code>gunicorn --workers 4 --bind 127.0.0.1:8000 woc.wsgi:application --name woc-server --log-level=info --worker-class=tornado --timeout=90 --graceful-timeout=10</code></p>
<p>When I make a request I am getting 502, Bad Gateway on the browser. Here is the server log <a href="http://pastebin.com/Ej5KWrWs" rel="noreferrer">http://pastebin.com/Ej5KWrWs</a></p>
<p>Some sections of the settings.py file where behaviour is changed based on hostname are</p>
<p>iUbuntu is the hostname of my laptop</p>
<pre><code>if socket.gethostname() == 'iUbuntu':
'''
Development mode
"iUbuntu" is the hostname of Ishan's PC
'''
DEBUG = TEMPLATE_DEBUG = True
else:
'''
Production mode
Anywhere else than Ishan's PC is considered as production
'''
DEBUG = TEMPLATE_DEBUG = False
if socket.gethostname() == 'iUbuntu':
'''Development'''
ALLOWED_HOSTS = ['*', ]
else:
'''Production Won't let anyone pretend as us'''
ALLOWED_HOSTS = ['domain.com', 'www.domain.com',
'api.domain.com', 'analytics.domain.com',
'ops.domain.com', 'localhost', '127.0.0.1']
</code></pre>
<p>(I don't get what's the purpose of this section of the code. Since I inherited the code from someone and the server was working I didn't bothered removing it without understanding what it does)</p>
<pre><code>if socket.gethostname() == 'iUbuntu':
MAIN_SERVER = 'http://localhost'
else:
MAIN_SERVER = 'http://domain.com'
</code></pre>
<p>I can't figure out what's the problem here. The same code runs fine with gunicorn on my laptop.</p>
<p>I have also made a small hello world node.js to serve on the port 8000 to test nginx configuration and it is running fine. So no nginx errors.</p>
<p>UPDATE:</p>
<p>I set DEBUG to True and copied the Traceback <a href="http://pastebin.com/ggFuCmYW" rel="noreferrer">http://pastebin.com/ggFuCmYW</a></p>
<p>UPDATE:</p>
<p>Thanks to the reply by @ARJMP. This indeed is the problem with celery consumer not getting connected to broker.</p>
<p>I am configuring celery like this : <code>app.config_from_object('woc.celeryconfig')</code> and the contents of celeryconfig.py are:</p>
<p><code>BROKER_URL = 'amqp://celeryuser:celerypassword@localhost:5672/MyVHost'
CELERY_RESULT_BACKEND = 'rpc://'</code></p>
<p>I am running the worker like this :<code>celery worker -A woc.async -l info --autoreload --include=woc.async -n woc_celery.%h</code></p>
<p>And the error that I am getting is:</p>
<p><code>consumer: Cannot connect to amqp://celeryuser:**@127.0.0.1:5672/MyVHost: [Errno 104] Connection reset by peer.</code></p>

<p>It seems like the persistant volume is correctly bounced but the pod are always in crash loop and restart every time. It's it because of the use of the initContainer or something wrong with my yaml ?</p>

Deploying WebSite builds to Azure from VSTS Release Management
|
<p>I'm kicking the tires on the preview for the Visual Studio Team Services new Release Management system. My scenario is a classic website (ASP.NET 4.5) with a Git repo hosted in VSTS. The build definition is successful as seen here:</p>
<p><a href="https://i.stack.imgur.com/MIwNS.png"><img src="https://i.stack.imgur.com/MIwNS.png" alt="enter image description here"></a> </p>
<p>It is set up to publish as an artifact that can be picked up by Release Manager as shown here:</p>
<p><a href="https://i.stack.imgur.com/dJn8J.png"><img src="https://i.stack.imgur.com/dJn8J.png" alt="enter image description here"></a></p>
<p>On the Release Manager side I have that artifact linked properly as shown here:</p>
<p><a href="https://i.stack.imgur.com/qBdoF.png"><img src="https://i.stack.imgur.com/qBdoF.png" alt="enter image description here"></a></p>
<p>And here you can see my environments as well as the associated tasks (all 3 are clones)</p>
<p><a href="https://i.stack.imgur.com/9hKp4.png"><img src="https://i.stack.imgur.com/9hKp4.png" alt="enter image description here"></a></p>
<p>When I run the release the build publishes fine, it connects to my subscription but when it attempts to find the package file it has the following error on line 101 of the output log:</p>
<p><strong>"No files were found to deploy with the search pattern 'C:\a\4fe43dd1a***.zip'"</strong></p>
<p>Here is the full output:</p>
<p><a href="https://i.stack.imgur.com/i8jmp.png"><img src="https://i.stack.imgur.com/i8jmp.png" alt="enter image description here"></a></p>
<p>This is where I am stuck as I assumed my artifact link via VSTS should resolve this path for me. Obviously I am missing an important piece of the puzzle somewhere, but I've followed the available documentation as best as I can.</p>
<p>If anyone has a solution or can point me in the right direction it would be much appreciated!</p>
<p><strong>--- EDIT ---</strong></p>
<p>I used the file picker to select a web deploy package (see below). I tried using the root website as well as the bin folder. Both attempts results in an error stating: <strong>"No files were found to deploy with search pattern 'C:\a\4fe43dd1a\Classic Website Definition\drop\ClassicWebsite\bin'"</strong> </p>
<p><a href="https://i.stack.imgur.com/Z2pit.png"><img src="https://i.stack.imgur.com/Z2pit.png" alt="enter image description here"></a></p>
<p><strong>--- EDIT 2 ---</strong></p>
<p>I added an MSBuild task to my BUILD process with the following MSBuildArguments</p>
<p><code>/p:OutDir=$(build.stagingDirectory) /p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true</code></p>
<p>and in my Copy/Publish Artifacts task I limited my output to only copy .zip files. Now in my RELEASE process when I navigate to find a "Web Deploy Package" the "drop" folder is empty. Here is a screenshot:</p>
<p><a href="https://i.stack.imgur.com/QjvMh.png"><img src="https://i.stack.imgur.com/QjvMh.png" alt="enter image description here"></a></p>
<p>I think I'm on the right path, I just need help figuring out to tune my BUILD tasks to generate the right artifacts for my RELEASE process to use. Any help would be appreciated.</p>

Symfony2: class 'Doctrine\Common\Collections\ArrayCollection' was not found in the chain configured namespaces

java.lang.InternalError: Can't connect to X11 window server for JVisualVM profiling session
|
<p>I have an Ubuntu server VM (<code>myapp01</code>) and have a Java application deployed there. The app has been acting wonky and I would like to profile it with JVisualVM. To do this I need to install X-Windows on my Windows 7 host, and then get the Ubuntu VM to export its X11 connection to my host when I tell it to run JVisualVM on the VM.</p>
<p>So I started by downloading XMing here:</p>
<pre><code>http://sourceforge.net/projects/xming/files/Xming/6.9.0.31/Xming-6-9-0-31-setup.exe/download
</code></pre>
<p>I used all default/recommended installation options, including using a normal PuTTy session and allowing public & private network access. After installing XMing, I launched it and verified it was running on my Windows host. I then opened up Cygwin and SSHed into the Ubuntu server:</p>
<pre><code>$ ssh myuser@myapp01
myuser@myapp01's password:

<p>I then export the display to what <em>appears</em> to be my host's IP:</p>
<pre><code>myuser@myapp01:~$ export DISPLAY=10.10.101.96
</code></pre>
<p>I then attempt to run JVisualVM:</p>
<pre><code>myuser@myapp01:~$ cd $JAVA_HOME

<p>Ideas? I am VPNed in, could that be affecting anything? Do I have XMing misconfigured somehow? Is my <code>export DISPLAY</code> command wrong?</p>

<p>Why am I getting the error? There is no inject keyword but I guess the <code>TestBed</code> might use it behind the scenes.</p>

UICollection View - Segue - did select specific cell , LOG

File "/usr/local/lib/python3.7/site-packages/airflow/models/taskinstance.py", line 1197, in handle_failure
task.on_failure_callback(context)
TypeError: on_failure_callback() takes 0 positional arguments but 1 was given
</code></pre>
<p>Why isn't <code>on_failure_callback</code> working?</p>
<p>Here is a visual representation of the DAG:</p>

RecyclerView: scrollToPosition not working
|
<p>I have a simple project displaying user text messages. I am currently not able to scroll the RecyclerView to the last received text message.
<br/>
My recyclerView is inside a very simple activity using the Coordinator layout:
<br/></p>
<pre><code><android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:background="@color/background"
tools:context="com.myproject.myproject.MessageActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_message" />
</android.support.design.widget.CoordinatorLayout>
</code></pre>
<p>And the content_message.xml:</p>
<pre><code><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="match_parent"
android:descendantFocusability="beforeDescendants"
android:focusable="true"
android:focusableInTouchMode="true"
android:orientation="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.textbutler.textbutler.MessageActivity"
tools:showIn="@layout/activity_message">
<!-- some views here -->
<android.support.v7.widget.RecyclerView
android:id="@+id/content_text"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:scrollbars="vertical" />
<!-- some views here -->
</LinearLayout>
</code></pre>
<p>The activity load the data through a basic loader. I force the access to the recyclerview on the UI thread and with a delay (just in case)</p>
<pre><code>public class MessageActivity extends AppCompatActivity {
private static final int URL_LOADER = 0;
private RecyclerView recyclerView;
private LinearLayoutManager layoutManager;
private MessageAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_message);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
initializeList(savedInstanceState);
}
private void initializeList(Bundle savedInstanceState) {
if (recyclerView == null) {
recyclerView = (RecyclerView) findViewById(R.id.content_text);
if (recyclerView == null)
return;
if (layoutManager == null) {
layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
layoutManager.setReverseLayout(true);
layoutManager.setStackFromEnd(true);
}
recyclerView.setLayoutManager(layoutManager);
final Activity me = this;
if (adapter == null) {
adapter = new MessageAdapter(new ObservableCallback() {
@Override
public void callback() {
// this function is called right after the recyclerview received notifyDataSetChanged
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
me.runOnUiThread(new Runnable() {
@Override
public void run() {
Log.d("ScrollingUI", "scrolltoposition " + adapter.getItemCount());
recyclerView.scrollToPosition(adapter.getItemCount() - 1);
}
});
}
}, 1000);
}
});
SMSByUserLoader loader = new SMSByUserLoader(this, adapter);
getSupportLoaderManager().initLoader(URL_LOADER, savedInstanceState, loader);
}
recyclerView.setAdapter(adapter);
}
}
</code></pre>
<p>}</p>
<p>When I run this code, the RecyclerView is perfectly filled. After a second I have the correct log but the view does not changed.
I already found various answers to this issue, but none of them seems to work in my case.
<br/>
Scrolling in the RecyclerView perfectly works.</p>

<p>Doesn't work!!!, I think that it must work because: "<strong>ON *.* TO 'root'@'%'</strong>"</p>
<p><strong>Looking for the difference:</strong>
'root'@'%' haven't CREATE TABLESPACE, EVENT and TRIGGER</p>
<pre><code>mysql> SELECT Host, Event_priv, Trigger_priv, Create_tablespace_priv,
authentication_string FROM mysql.user WHERE USER = "root";

+-----------+------------+--------------+------------------------+--------------
---------+
2 rows in set (0.01 sec)

</code></pre>
<p>But, I think that is not root of problem...</p>
<p>Maybe The solution will be, to use: <strong>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'</strong>, but I think "all privileges" have other thing than "an amount of privileges".</p>

jquery ajax readystate 0 responsetext status 0 statustext error
|
<p>I am getting the following error: <code>jquery ajax readystate 0 responsetext status 0 statustext error</code> when giving it: <code>url(http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm)</code>, however it's working fine when I give it <code>url(localhost:""/embparse_page)</code> on my localhost. </p>
<p>I have tried using the headers which I found on a Google search, and I have used <code>beforeSend:""</code> too, but it's still not working.</p>
<p>I think the main problem is: <code>XMLHttpRequest cannot load http://www.tutorialspoint.com/prototype/prototype_ajax_response.htm. Origin "local server" is not allowed by Access-Control-Allow-Origin.</code> but I don't understand it. </p>
<p>Can anyone please explain the problem to me, as I'm quite new to this.</p>

Is it possible to refresh partial frequently using Ajax?

Chart.js: Bar Chart Click Events
|
<p>I've just started working with Chart.js, and I am getting very frustrated very quickly. I have my stacked bar chart working, but I can't get the click "events" to work.</p>
<p>I have found a <a href="https://github.com/chartjs/Chart.js/issues/577#issuecomment-55897221">comment on GitHub by <code>nnnick</code></a> from Chart.js stating to use the function <code>getBarsAtEvent</code>, even though this function cannot be found in the <a href="http://www.chartjs.org/docs/#bar-chart-chart-options">Chart.js documentation</a> at all (go ahead, do a search for it). The documentation does mention the <code>getElementsAtEvent</code> function of the <code>chart</code> reference, but that is for Line Charts only.</p>
<p>I set an event listener (the right way) on my canvas element:</p>
<pre><code>canv.addEventListener('click', handleClick, false);
</code></pre>
<p>...yet in my <code>handleClick</code> function, <code>chart.getBarsAtEvent</code> is undefined!</p>
<p>Now, in the Chart.js document, there is a statement about a different way to register the click event for the bar chart. It is much different than <code>nnnick</code>'s comment on GitHub from 2 years ago.</p>
<p>In the <a href="http://www.chartjs.org/docs/#getting-started-global-chart-configuration">Global Chart Defaults</a> you can set an <code>onClick</code> function for your chart. I added an <code>onClick</code> function to my chart configuration, and it did nothing...</p>
<p>So, how the heck do I get the on-click-callback to work for my bar chart?!</p>
<p>Any help would be greatly appreciated. Thanks!</p>
<p><strong>P.S.:</strong> I am not using the master build from GitHub. I tried, but it kept screaming that <code>require is undefined</code> and I was not ready to include CommonJS just so that I could use this chart library. I would rather write my own dang charts. Instead, I downloaded and am using the <a href="https://raw.githubusercontent.com/nnnick/Chart.js/v2.0-dev/dist/Chart.js"><strong>Standard Build</strong></a> version that I downloaded straight from the link at the top of the <a href="http://www.chartjs.org/docs/">documentation page</a>.</p>
<p><strong>EXAMPLE:</strong> Here is an example of the configuration I am using:</p>
<pre><code>var chart_config = {
type: 'bar',
data: {
labels: ['One', 'Two', 'Three'],
datasets: [
{
label: 'Dataset 1',
backgroundColor: '#848484',
data: [4, 2, 6]
},
{
label: 'Dataset 2',
backgroundColor: '#848484',
data: [1, 6, 3]
},
{
label: 'Dataset 3',
backgroundColor: '#848484',
data: [7, 5, 2]
}
]
},
options: {
title: {
display: false,
text: 'Stacked Bars'
},
tooltips: {
mode: 'label'
},
responsive: true,
maintainAspectRatio: false,
scales: {
xAxes: [
{
stacked: true
}
],
yAxes: [
{
stacked: true
}
]
},
onClick: handleClick
}
};

Android custom ArrayAdapter getView method called multiple times - resetting dynamic TextView value

<p>The getView method in my custom ArrayAdapter is getting called multiple times, which I assume it is meant to. Problem is, I have a quantity TextView which is dynamically set but when you scroll and the box goes off screen the value disappears. I am not sure what I am doing wrong and Google is not proving to be much help. Hopefully someone here can help me.</p>

creating a datagridview form in c#
|
<p>I`m new to c# and windows form applications.
Right now, I want to create a Datagridview within my form, whose rows I want to fill with the properties of a business object. I followed the example from this msdn page: <a href="http://msdn.microsoft.com/en-us/library/y0wfd4yz.aspx" rel="nofollow">How to: Bind Objects to Windows Forms DataGridView Controls</a> and created my own program, but instead of getting a similar result as in the msdn example I get a datagridview with three empty rows.

bindingSource1.Add(new Test("bli", "bla", "blop", "ha", "ho", "he"));

getting all months between 2 dates
|
<p>I created a function that returns an array containing each month, starting from a supplied carbon date and ending on the current date.</p>
<p>Although the function is doing what it is supposed to do, it looks hideous. Clearly my programming skills arent yet what they're supposed to be. Surely there must be a better way to achieve what i want.</p>
<p>My code looks like this:</p>
<pre><code> class DateUtilities {
protected $months = ['january', 'february', 'march', 'april', 'may', 'june', 'july', 'august', 'september', 'october', 'november', 'december'];
public function getMonthListFromDate(Carbon $date)
{
$monthArray = array();
$today = Carbon::today();
$currentYear = $today->copy()->format('Y');
$currentMonth = strtolower($today->copy()->format('F'));
$startYear = $date->copy()->format('Y');
$startMonth = strtolower($date->copy()->format('F'));
for($i = $startYear; $i <= $currentYear; $i ++) {
foreach($this->months as $monthIndex => $month) {
if (($monthIndex >= array_search($startMonth, $this->months) && $i == $startYear) ||
($monthIndex <= array_search($currentMonth, $this->months) && $i == $currentYear) ||
($i != $startYear && $i != $currentYear)) {
$formattedMonthIndex = ($monthIndex + 1);
if($formattedMonthIndex < 10) {
$monthArray['0' . $formattedMonthIndex . '-' . $i] = $month . ' ' . $i;
} else {
$monthArray[$formattedMonthIndex . '-' . $i] = $month . ' ' . $i;
}
}
}
}
return $monthArray;
}
}
</code></pre>
<p>and the result is:</p>
<pre><code>array:25 [▼
"03-2013" => "march 2013"
"04-2013" => "april 2013"
"05-2013" => "may 2013"
"06-2013" => "june 2013"
"07-2013" => "july 2013"
"08-2013" => "august 2013"
"09-2013" => "september 2013"
"10-2013" => "october 2013"
"11-2013" => "november 2013"
"12-2013" => "december 2013"

"02-2015" => "february 2015"
"03-2015" => "march 2015"
]
</code></pre>
<p>Can anyone help me improve this code?</p>
<p>EDIT:</p>
<p>After the great tips i ended up with the following:</p>
<pre><code>class DateUtilities {
public function getMonthListFromDate(Carbon $start)
{
$start = $start->startOfMonth();
$end = Carbon::today()->startOfMonth();
do
{
$months[$start->format('m-Y')] = $start->format('F Y');
} while ($start->addMonth() <= $end);
return $months;
}
</code></pre>
<p>}</p>
<p>Thank you for the help guys!!</p>

Reading from .data file into Java- how do I store the information in an array of arrays?
|
<p>I have the following Java class, which I'm using to read a .data file:</p>
<pre><code>import java.io.*;
import java.util.Scanner;
public class ReadFile {
static File file;
String[] columns = new String[]{"personID", "lastName", "firstName", "street", "city"};
String[] data = new String[100];
String filename = "D:\\Users\\Elgan Frost\\Desktop\\careers\\Smart Stream Associate Software Engineer (Java) - Bristol\\assessment\\srcPerson.data";
public ReadFile(File f) throws FileNotFoundException {
// TODO Auto-generated constructor stub
try{
//File = new File("D:\\Users\\Elgan Frost\\Desktop\\careers\\Smart Stream Associate Software Engineer (Java) - Bristol\\assessment\\srcPerson.data");
f = new File("D:\\Users\\Elgan Frost\\Desktop\\careers\\Smart Stream Associate Software Engineer (Java) - Bristol\\assessment\\src\\Person.data");
Scanner scanner = new Scanner(f);
while(scanner.hasNextLine()){
System.out.println(scanner.nextLine());
}
scanner.close();
}
finally{
}
}
public void read(File file2) throws IOException{
FileReader fr = new FileReader("D:\\Users\\Elgan Frost\\Desktop\\careers\\Smart Stream Associate Software Engineer (Java) - Bristol\\assessment\\src\\Person.data");
BufferedReader br = new BufferedReader(fr);
String line;
int i = 0;
while((line = br.readLine())!= null){
data[i] = line;
System.out.println(data[i]);
i++;
}
br.close();
String[] dataNew = new String[i];
System.arraycopy(data, 0, dataNew, 0, i);
data = dataNew;
System.out.println("Data length: " + data.length);
}
}
</code></pre>
<p>To give you a more complete understanding of my code, I also have the following Java class, which contains my main method:</p>
<pre><code>import java.io.*;
public class Person {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
ReadFile rf = new ReadFile(f);
rf.read(ReadFile.file);
}
static File f;
public String id;
public String lastName;
public String firstName;
public String street;
public String city;
public void readPerson() throws FileNotFoundException{
//File f = new File("Smart Stream Associate Software Engineer (Java) - Bristol/assessment/src/Person.java");
//InputStream IS = new FileInputStream(f);
}
}
</code></pre>
<p>Currently, when I run my program, the console displays two lines that say, "Person.data...." and give the filepath of the .data file that is being read, which will have come from the lines <code>System.out.println(scanner.nextLine());</code> and <code>System.out.println(data[i]);</code> in my ReadFile.java class, as well as the line "Data length: 1", which will have come from the line <code>System.out.println("Data length: " + data.length);</code> at the end of the class.</p>
<p>I assume that this means that the program has read the first two lines of the .data file, but only stored the first.</p>
<p>What I want to happen, is for it to read the first line, store that in a String, then divide the String up into separate Strings wherever a 'space' appears, and store each of those Strings in an element of the array of Strings that I created at the start of the class- by using the line:</p>
<pre><code>String[] columns = new String[]{"personID", "lastName", "firstName", "street", "city"};
</code></pre>
<p>The separate Strings should be stored to each one in that order- so the first String (before the first space in the original String) would be stored in "personID", the second (after the first space, before the second) would be stored in "lastName", etc.</p>
<p>What I then want to do, is read each of the next lines in the file in turn, storing the elements from each line into the next 'row' of my 'columns' String array (basically creating a table of data, using an array of arrays) whereby the first element of each array is a "personID", the second is a "lastName", etc.</p>
<p>I want to do this until I reach the end of the file, and then print the contents of a couple of elements of the 'columns' array, just to show that it has worked.</p>
<p>I'm not sure how I would go about this, and was just wondering if anyone could point me in the right direction?</p>

<p>I have created a database with two tables, "goals" and "partgoals". The practial use is to make a savings goal (money) and have milestones along the way (partgoals). I want the partgoals obviously be linked to a specific goal. The relationships are created but I run into trouble when trying to create my seed data.</p>
<p>My goal is to set up two goals table like this (GoalsTableSeeder.php):</p>
<pre><code><?php
class GoalsTableSeeder extends Seeder {
public function run()
{
DB::table('goals')->delete();
$goals = array(
array(
'max' => 1850000,
'avgsav' => 3500,
'duedate' => date('2015-03-15'),
'created_at' => new DateTime,
'updated_at' => new DateTime,
),
array(
'max' => 1100000,
'avgsav' => 5000,
'duedate' => date('2013-11-15'),
'created_at' => new DateTime,
'updated_at' => new DateTime,
)
);
DB::table('goals')->insert( $goals );
}
}
</code></pre>
<p>And my partgoals table like this (PartgoalsTableSeeder.php):</p>
<pre><code><?php
class PartgoalsTableSeeder extends Seeder {
public function run()
{
DB::table('partgoals')->delete();
$partgoals = array(
array(
'id' => 1,
'milestone' => 100000,
'duedate' => date('2014-03-15'),
'created_at' => new DateTime,
'updated_at' => new DateTime,
),
array(
'id' => 1,
'milestone' => 20000,
'duedate' => date('2013-06-15'),
'created_at' => new DateTime,
'updated_at' => new DateTime,
),
array(
'id' => 2,
'milestone' => 400000,
'duedate' => date('2013-09-15'),
'created_at' => new DateTime,
'updated_at' => new DateTime,
),
array(
'id' => 2,
'milestone' => 200000,
'duedate' => date('2014-10-15'),
'created_at' => new DateTime,
'updated_at' => new DateTime,
)
);
DB::table('partgoals')->insert( $partgoals );
}
}
</code></pre>
<p>The migration table for "goals":</p>
<pre><code><?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateGoalsTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('goals', function(Blueprint $table)
{
$table->increments('id');
$table->integer('max');
$table->float('avgsav');
$table->date('duedate');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('goals');
}
}
</code></pre>
<p>The migration table for partgoals:</p>
<pre><code><?php
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreatePartgoalsTable extends Migration {
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('partgoals', function(Blueprint $table)
{
$table->foreign('id')
->references('id')->on('goals')
->onDelete('cascade');
$table->increments('id');
$table->float('milestone');
$table->date('duedate')->nullable();
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::drop('partgoals');
}
}
</code></pre>

<p>When this starts I get an </p>
<pre><code>SQL Error: 0, SQLState: 08006 - An I/O error occured while sending to the backend.
</code></pre>
<p>but after that it's only:</p>
<pre><code>SQL Error: 0, SQLState: 08003 - This connection has been closed.
</code></pre>
<p>The problem is: I have set testOnBorrow, so I'd expect to get only open connections.</p>
<p>If that helps: the pool ususaly contains a mix of good and bad connections, and the problem seems to clear up over time, but I had the server running for >12h and there were still bad connections returned.
After a restart evertything is working fine (for a time).</p>
<p>I have debugged the problem some more and it seems like pool is returning bad connections, e.g. if after I have all connections killed on DB I get:</p>
<pre><code>SQL Error: 0, SQLState: 57P01
</code></pre>
<p>and then the usual stuff - the killed connections are returned from the pool.
The question is: is it an application problem?</p>
<p>I tried purging the pool via JMX but that doesn't seem to have any effect.
Another weird thing is that even though app is apparently not doing anything (checked via thread dump) the JMX bean is showing 7 active connections and 0 idle connections. When I execute a request requiring DB access I get a response immediately (depite there being no idle connections available), but JMX shows 7 active and 0 idle connections after that.</p>
<p>PS. Maybe I'm missing something obvious and this is a connection management issue on my part? I'm using JPA EntityManager configured via persistence.xml, so maybe I'm doing something wrong and the connections are not closed(returned) properly after use?</p>

Spring Boot YML and StandAlone Tomcat 8 Server
|
<p>I have the following directory structure/config file:</p>
<pre><code>src/main/resource/config:
application.yml
application-dev.yml
application-sit.yml
</code></pre>
<p>Note according to the "<strong>Bootiful Configuration</strong>" <a href="https://spring.io/blog/2015/01/13/configuring-it-all-out-or-12-factor-app-style-configuration-with-spring" rel="noreferrer">https://spring.io/blog/2015/01/13/configuring-it-all-out-or-12-factor-app-style-configuration-with-spring</a>:</p>
<blockquote>
<p>Spring Boot will read the
properties in src/main/resources/application.properties by default. If
a profile is active, it will also automatically reads in the
configuration files based on the profile name, like
src/main/resources/application-foo.properties where foo is the current
profile. If the Snake YML library is on the classpath, then it will
also automatically load YML files.</p>
</blockquote>
<p>Since snake YML jar is in class path if I set <code>--spring.profiles.active=dev</code> as a
program arg in eclipse run configuration and use this as my main method Ever thing works as expected:</p>
<pre><code> public static void main(String[] args) {
SpringApplication app = new SpringApplication(Application.class);
SimpleCommandLinePropertySource source = new SimpleCommandLinePropertySource(args);
// Check if the selected profile has been set as argument.
// if not the development profile will be added
addDefaultProfile(app, source);
app.run(args);
}
/**
* Set a default profile if it has not been set
*/
private static void addDefaultProfile(SpringApplication app, SimpleCommandLinePropertySource source) {
if (!source.containsProperty("spring.profiles.active")) {
app.setAdditionalProfiles(Constants.SPRING_PROFILE_DEVELOPMENT);
}
}
</code></pre>
<p>(Please note the main method reference above is from the following class used in my code: <a href="https://github.com/jarias/generator-jhipster-ember/blob/master/app/templates/src/main/java/package/_Application.java" rel="noreferrer">https://github.com/jarias/generator-jhipster-ember/blob/master/app/templates/src/main/java/package/_Application.java</a>)</p>
<p>Everything works as expected for spring.profile.active=dev. Which means that both:
<strong>application.yml</strong>(loaded by default) and <strong>application-dev.yml</strong>(active profile) property files are loaded and <strong>excludes</strong> <em>application-sit.yml</em> since sit isn't an active profile.</p>
<p>This embedded container works great for dev testing. However I want to release this into production by generating a war and deploy it to a standalone Tomcat8 Server. </p>
<p>For that I created an implementation of WebApplicationInitializer which is required by Tomcat8 server to automatically detect, bootstrap and start spring application on the standalone server.</p>
<pre><code>@Configuration
public class WebAppInit implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
ApplicationContext context = new AnnotationConfigApplicationContext(Application.class);
}
}
</code></pre>
<p>After deploying the war I receive the following error I attempt to start the standalone server and receive the following error :</p>
<blockquote>
<p>Caused by: org.springframework.beans.factory.enter code
hereBeanCreationException: Could not autowire field: private
java.lang.String com.titlefeed.config.db.DbConfigJPA.databaseUrl;
nested exception is java.lang.IllegalArgumentException: Could not
resolve placeholder spring.data.postgres.uri' in string value
"${spring.data.postgres.uri}"</p>
</blockquote>
<p>Which implies the Tomcat Server/Spring <strong>isnt</strong> loading the application-dev.yml since that contains the properties: <strong>spring.data.postgres.uri</strong></p>
<p>So I attempted the following two solutions</p>
<ol>
<li>added <code>-Dspring.profiles.active=dev</code> to JAVA_OPTS in tomcat/bin/catalina.sh</li>
<li>added <code>spring.profiles.active=dev</code> to tomcat/conf/catalina.properties</li>
</ol>
<p>And neither of them worked. How can I get the standalone tomcat server to load the yml file associated with the spring.profiles.active property.</p>
<p>It works fine for the embedded springboot server started from eclipse but doesnt for an standalong server ?</p>
<p><strong>EDIT1: M. Deinum</strong> - Implemented your suggested solution below however still got the following error:</p>
<p><code>Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.data.postgres.uri' in string value "${spring.data.postgres.uri}</code></p>
<p>It seems like the -Dspring.profiles.active=dev isn't getting set.</p>
<pre><code>@Configuration
public class WebAppInit extends SpringBootServletInitializer {
@Override
protected WebApplicationContext createRootApplicationContext(
ServletContext servletContext) {
log.info("Properly INITALIZE spring CONTEXT");
ApplicationContext context = new AnnotationConfigApplicationContext(Application.class);
servletContext.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, context);
return super.createRootApplicationContext(servletContext);
}
}
</code></pre>
<p><strong>EDIT 2 ACV:</strong> - Adding "--spring.profiles.active=dev" as apart of JAVA_OPTS variable in the startup script: tomcat/bin/catalina.sh is not a viable option</p>
<p>E.g:</p>
<pre><code> JAVA_OPTS="$JAVA_OPTS --spring.profiles.active=dev ...etc
</code></pre>
<p>Gives the following error:</p>
<blockquote>
<p>Unrecognized option: --spring.profiles.active=dev Error: Could not
create the Java Virtual Machine."</p>
</blockquote>
<p><strong>EDIT 3:</strong>
Amended <strong>application.yml</strong> to include the following property</p>
<pre><code>spring:
profiles:
active: dev
</code></pre>
<p>Redeployed the war. Went to the exploded tomcat directory location to ensure the property was present <strong>webapps/feedserver/WEB-INF/classes/config/application.yml</strong></p>
<p>And the issue still occurred.</p>
<p><strong>EDIT 4:</strong> Added application.properties under the tomcat exploded webdir: webapps/feedserver/WEB-INF/classes/application.properties:</p>
<pre><code>spring.profiles.active=dev
spring.data.postgres.uri=jdbc:postgresql://localhost:5432/feedserver
</code></pre>
<p>restarted tomcat and the issue still occurred.</p>
<p>Its seems like its not picking up either <strong>application.properties</strong> or <strong>application.yml</strong></p>
<p><strong>EDIT 5</strong> Used the recommended way to start the spring boot server for an external container:</p>
<pre><code>@Configuration
public class WebAppInit extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
</code></pre>
<p><strong>Edit 6:</strong></p>
<p>I added <strong>-Dspring.profiles.active=dev</strong> to the start command args:</p>
<pre><code>/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java -Djava.util.logging.config.file=/Users/shivamsinha/Desktop/Programming/tomcat/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Dlog4j.rootLevel=ERROR -Dlog4j.rootAppender=console -DENV=dev -Dlog4j.configuration=/WEB-INF/classes/properties/log4j.properties -DTOMCAT_DIR=WEB-INF/classes/ -Djava.endorsed.dirs=/Users/shivamsinha/Desktop/Programming/tomcat/endorsed -classpath /Users/shivamsinha/Desktop/Programming/tomcat/bin/bootstrap.jar:/Users/shivamsinha/Desktop/Programming/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/Users/shivamsinha/Desktop/Programming/tomcat -Dcatalina.home=/Users/shivamsinha/Desktop/Programming/tomcat -Djava.io.tmpdir=/Users/shivamsinha/Desktop/Programming/tomcat/temp org.apache.catalina.startup.Bootstrap -Dspring.profiles.active=dev start
</code></pre>
<p>However I stil get the following exception in the logs:</p>
<pre><code>Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private java.lang.String com.titlefeed.config.db.DbConfigJPA.databaseUrl; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.data.postgres.uri' in string value "${spring.data.postgres.uri}"

How do I add a footer row in a WPF datagrid?

<p>How Do I Add a footer row in WPF datagrid? I had to add a row in a WPF datagrid for the sum of each column, I don't want to use any dll or telerik and some things like that only use Microsoft components to do this. I'm trying to do it this way:</p>

Print results in MySQL format with Python
|
<p>What is the easiest way to print the result from MySQL query in the same way MySQL print them in the console using Python? For example I would like to get something like that:</p>
<pre><code>+---------------------+-----------+---------+
| font | documents | domains |
+---------------------+-----------+---------+
| arial | 99854 | 5741 |
| georgia | 52388 | 1955 |
| verdana | 43219 | 2388 |
| helvetica neue | 22179 | 1019 |
| helvetica | 16753 | 1036 |
| lucida grande | 15431 | 641 |
| tahoma | 10038 | 594 |
| trebuchet ms | 8868 | 417 |
| palatino | 5794 | 177 |
| lucida sans unicode | 3525 | 116 |
| sans-serif | 2947 | 216 |
| times new roman | 2554 | 161 |
| proxima-nova | 2076 | 36 |
| droid sans | 1773 | 78 |
| calibri | 1735 | 64 |
| open sans | 1479 | 60 |
| segoe ui | 1273 | 57 |
+---------------------+-----------+---------+
17 rows in set (19.43 sec)
</code></pre>
<p>Notice: I don't know the max width for each column a priori, and yet I would like to be able to that without going over the table twice. Should I add to the query length() for each column? How does MySQL do it, in order to not impact severely the memory or processing time? </p>
<p><em>EDIT</em></p>
<p>I did not think it was relevant to the question but, this is the query I send:</p>
<pre><code>SELECT font.font as font,count(textfont.textid) as documents, count(DISTINCT td.domain) as domains
FROM textfont
RIGHT JOIN font
ON textfont.fontid = font.fontid
RIGHT JOIN (
SELECT text.text as text,url.domain as domain, text.textid as textid
FROM text
RIGHT JOIN url
ON text.texturl = url.urlid) as td
ON textfont.textid = td.textid
WHERE textfont.fontpriority <= 0
AND textfont.textlen > 100
GROUP BY font.font
HAVING documents >= 1000 AND domains >= 10
ORDER BY 2 DESC;
</code></pre>
<p>And this is the python code I use:</p>
<pre><code>import MySQLdb as mdb
print "%s\t\t\t%s\t\t%s" % ("font","documents","domains")
res = cur.execute(query , (font_priority,text_len,min_texts,min_domains))
for res in cur.fetchall():
print "%s\t\t\t%d\t\t%d" % (res[0],res[1],res[2])
</code></pre>
<p>But this code produces a messy output due to different widths.</p>

Adding the ZeroMQ PHP extension to XAMPP on Windows 10 and PHP7
|
<p>I am having issues adding the ZeroMQ PHP extension to XAMPP. </p>
<p>Setup: Windows 10, PHP7, XAMPP (7.0.9)</p>
<p><strong>Steps I already took:</strong></p>
<ol>
<li><p>Added PHP (<code>D:\xampp7\php</code>) and PHP extensions (<code>D:\xampp7\php\ext</code>) directories to system variable (PATH)</p></li>
<li><p>Followed the instructions on <a href="http://zeromq.org/bindings%3Aphp#toc4" rel="noreferrer">zeromq.org</a>. I downloaded <a href="http://windows.php.net/downloads/pecl/releases/zmq/1.1.3/php_zmq-1.1.3-7.0-ts-vc14-x86.zip" rel="noreferrer">x86ts</a> version from the <a href="http://pecl.php.net/package/zmq/1.1.3/windows" rel="noreferrer">pecl repository</a> as the listed snapshot link (<a href="http://snapshot.zero.mq/" rel="noreferrer">http://snapshot.zero.mq/</a>) was down.</p></li>
<li><p>Copied <code>libzmq.dll</code> into PHP directory and <code>php_zmq.dll</code> into the PHP extension directory </p></li>
<li><p>Updated <code>php.ini</code> (<code>D:\xampp7\php\php.ini</code>) by adding <code>extension=php_zmq.dll</code> and checked the extensions directory which is <code>extension_dir="D:\xampp7\php\ext"</code></p></li>
<li><p>Restarted XAMPP via the control panel.</p></li>
</ol>
<p>The Apache error log shows the following:</p>

<hr>
<p><strong>Update:</strong></p>
<p>It looks like the module cannot be found, but if I add the x64 Version the Apache error log indicates that the module is not a not a valid Win32 application.</p>

<hr>
<p><strong>Solution:</strong></p>
<p>Adding <code>LoadFile "D:/xampp7/php/libzmq.dll"</code>to httpd.conf fixed my issue.</p>

Docker - Failed to connect to localhost port 4000: Connection refused
|
<p>Hi I'm very new to Docker, I'm trying to get familiar with Docker by following the tutorial on official site. Now I get stuck at part 2 of the tutorial (where you can check up the link here => <a href="https://docs.docker.com/get-started/part2/#run-the-app" rel="noreferrer">https://docs.docker.com/get-started/part2/#run-the-app</a>)</p>
<p>I have sample application code, Dockerfile, and requirements.txt exactly same as the offical tutorial</p>
<pre><code>$ ls
app.py Dockerfile requriements.txt
</code></pre>
<p>My Dockerfile looks like this</p>
<pre><code>FROM python:2.7-slim
WORKDIR /app
ADD . /app
RUN pip install -r requriements.txt
EXPOSE 80
ENV NAME World
CMD ["python", "app.py"]
</code></pre>
<p>All 3 files have file content/code exactly same as the tutorial also. I was able to build image registry with this command</p>
<pre><code>$ docker build -t friendlyhello .
</code></pre>
<p>Everything looks great. Now I had sample project image registry.</p>
<pre><code>$ docker images
REPOSITORY TAG IMAGE ID CREATED
friendlyhello latest 82b8a0b52e91 39 minutes ago
python 2.7-slim 1c7128a655f6 5 days ago
hello-world latest 48b5124b2768 4 months ago
</code></pre>
<p>I then ran the app according to the official tutorial with this command</p>
<pre><code>$ docker run -d -p 4000:80 friendlyhello
c1893f7eea9f1b708f639653b8eba20733d8a45d3812b442bc295b43c6c7dd5c
</code></pre>
<p><strong>Edit</strong>: This is my container after ran above command</p>
<pre><code>$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS
c1893f7eea9f friendlyhello "python app.py" 15 minutes ago Up 16 minutes
</code></pre>
<p>And the official tutorial guides readers to have a look at <code>http://localhost:4000</code> as they have already mapped machine port <code>4000</code> to container port <code>80</code></p>
<p>Unfortunately, I couldn't get any response from that URL.</p>
<pre><code>$ curl http://localhost:4000
curl: (7) Failed to connect to localhost port 4000: Connection refused
</code></pre>
<p>I'm totally newbie and I have no idea what to do....How can I get it to work ?
Thanks in advance for any response.</p>
<p><strong>Edit</strong>: I did as @johnharris85 suggested. Below is the output</p>
<pre><code>$ curl http://$(echo docker-machine ip default):4000
curl: (6) Couldn't resolve host 'docker-machine'
curl: (6) Couldn't resolve host 'ip'
curl: (6) Couldn't resolve host 'default'
</code></pre>
<p>It seems like it doesn't work either.</p>
<p><strong>Edit</strong>: @johnharris85 corrected his suggestion and @user8023051 clarify how this command come from and what is going on under the hood. It is working now :) Thanks</p>
<pre><code>$ curl http://$(docker-machine ip default):4000
<h3>Hello World!</h3><b>Hostname:</b> c1893f7eea9f<br/><b>Visits:</b> <i>cannot connect to Redis, counter disabled</i>

Reactjs : Adding element to array object in Json
|
<p>I have just started with reactjs and working on form component(formsy).I am trying to add and element to the existing array element but I am not able to do so. below is what I have tried and what I have got so far.</p>
<p>JSON Object - </p>
<pre><code>{
"details": {
"someInnerObj": "v3",
"innerObj": {
"key1": "",
"key2": ""
},
"ArrayObject": [{
"type": "sometype",
"somedesign": {
"A": "",
"B": "",
"C": "",
"D": ""
},
"somedev": {
"a": "",
"b": "",
"c": "",
"d": ""
}
}
],
"code": "code",
"isThis": "true"
}
}
</code></pre>
<p>what i am trying to achieve here is adding and element to ArrayObject like below</p>
<pre><code>"ArrayObject": [{
"type": "sometype",
"somedesign": {
"A": "",
"B": "",
"C": "",
"D": ""
},
"somedev": {
"a": "",
"b": "",
"c": "",
"d": ""
}
},
{
"type": "sometype1",
"somedesing1": {
"A1": "",
"B1": "",
"C1": "",
"D1": ""
},
"somedev1": {
"a1": "",
"b1": "",
"c1": "",
"d1": ""
}
}
]
</code></pre>
<p>I am putting new element using the field value of json object as
"details.ArrayObject[1]". but it instead of adding the new element is creating new key as given below and removing the existing - </p>
<pre><code>"ArrayObject": {
"[1]": {
"type": "sometype1",
"somedesing1": {
"A1": "",
"B1": "",
"C1": "",
"D1": ""
},
"somedev1": {
"a1": "",
"b1": "",
"c1": "",
"d1": ""
}
}
}
</code></pre>
<p>Could anyone please help out here ?</p>
<p>thanks.</p>

NHibernate mapping - one-to-one (or one-to-zero)
|
<p>NHibernatians!</p>
<p>I have a table [dbo].[Wibble] and another table [dbo].[WibbleExtended].</p>
<p>[Wibble] is the main table and [WibbleExtended] is an optional table where some other fields are stored. There are far fewer entries in the [WibbleExtended] table than the main [Wibble] table. I think this was done back in the day to cure some space issues (Wibble has many rows and WibbleExtened has many columns).</p>
<p>The ID for each table is the same and comes from an external source. </p>
<p>I.e.</p>
<pre><code>[dbo].[Wibble].[WibbleId]
</code></pre>
<p>and </p>
<pre><code>[dbo].[WibbleExtended].[WibbleId]
</code></pre>
<p>are identical and is how the two tables relate.</p>
<p>N.B. I can't change the schema. I'm shoe-horning this onto a legacy system that I have almost no control over.</p>
<p>Searching around it seems that one-to-one mappings are problematic and the prevailing wisdom is to use two many-to-one mappings.</p>
<p>My mappings currently are:</p>
<pre><code><class name="Wibble" table="Wibble" >
<id name="Id" column="WibbleId" type="Int32">
<generator class="assigned"/>
</id>
<many-to-one name="WibbleExtended" class="WibbleExtended" column="WibbleId" not-null="false" cascade="all"/>
</class>
</code></pre>
<p>And</p>
<pre><code><class name="WibbleExtended" table="WibbleExtended" >
<id name="Id" column="WibbleId" type="Int32">
<generator class="assigned" />
</id>
<many-to-one name="Wibble" class="Wibble" column="WibbleId" not-null="true" />
</class>
</code></pre>
<p>The problem with this is I'm getting errors such as </p>
<pre><code>System.IndexOutOfRangeException: Invalid index n for this SqlParameterCollection with Count=n.
</code></pre>
<p>I've looked around and this does look like the correct strategy, it's just falling at the final hurdle.</p>
<p>Is the problem the id generator? Other aspect of the mapping?</p>
<p>Free mince pie for the correct answer.</p>
<p>EDIT: Ok - here's what I did to solve this via @James Gregory.</p>
<ol>
<li><p>Moved the unit tests from the WibbleExtended tests to the Wibble test class and made the necessary modifications.</p></li>
<li><p>Added the following to the Wibble.hbm.xml </p>
<pre><code><join table="WibbleExtended" optional="true">
<key column="WibbleId"/>
<property name="Blah1" column="Blah1" type="String" length="2000" not-null="false" />
<property name="Blah2" column="Blah2" type="String" length="1000" not-null="false" />
</join>
</code></pre></li>
<li><p>Added the corresponding properties to the Wibble POCO.</p></li>
<li><p>Deleted all code relating to WibbleExtended.</p></li>
<li><p>Run tests, all passed, checked in. Build passed. Went for an xmas beer (hence it's been a couple of days before I updated this! :-))</p></li>
</ol>

JavaFX: Apply text color to TableCell using custom style sheet?
|
<p>JavaFX: <strong>How can I apply text color to a TableCell using a custom style sheet?</strong></p>
<p>It works fine, when I use <code>setTextFill()</code> in my CellFactory directly, but I want to apply custom style using an external CSS file. I could prove that my CSS class is applied, since the font becomes bold. The CSS file's font color, however, is not applied.</p>
<pre><code>@Override
protected void updateItem(MyObject item, boolean empty) {
super.updateItem(item, empty);
if (null != item) {
// EITHER:
this.getStyleClass().add("styleImportant"); // Does NOT set color.
// OR:
this.setTextFill(Color.RED); // Does set color.
}
else {
this.getStyleClass().remove("styleImportant");
}
}
</code></pre>
<p>Style sheet:</p>
<pre><code>.styleImportant {
-fx-font-weight: bold; /** Does work. */
-fx-text-fill: red; /** Does NOT work. */
}
</code></pre>
<p>It is somehow related to specificity of CSS selectors, but I did not manage to find any valid setup.</p>
<hr>
<p><strong>Edit:</strong> I managed to apply both, a custom text color and background color, using CSS. My implementation now uses a <code>Label</code> that is wrapped in a <code>VBox</code> to make the background color fill the entire table cell. However, I still had some issues with background color not being cleared when removing the custom style.</p>
<p><strong>Is there any better solution than applying a <em>clear style</em>?</strong></p>
<pre><code>colExample.setCellFactory(new Callback<TableColumn<Example, Example>, TableCell<Example, Example>>() {
@Override
public TableCell<Example, Example> call(TableColumn<Example, Example> tableColumn) {
return new TableCell<Example, Example>() {
private VBox container;
private Label text;
// Anonymous constructor
{
this.container = new VBox();
this.text = this.createLabel();
this.container.getChildren().add(this.text);
this.setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
this.setStyle("-fx-padding: -1 -1 -1 -1;"); // Remove padding from cell
this.setGraphic(this.container);
}
private final Label createLabel() {
Label label = new Label();
VBox.setVgrow(label, Priority.ALWAYS);
label.setMaxWidth(Double.MAX_VALUE);
label.setMaxHeight(Double.MAX_VALUE);
label.setAlignment(Pos.CENTER);
return label;
}
@Override
protected void updateItem(Example example, boolean empty) {
super.updateItem(example, empty);
// Reset column styles
if (null != this.text && null != this.text.getStyleClass()) {
String[] possibleStyles = new String[] { "styleImportant", "clearStyle" };
for (String style: possibleStyles) {
if (this.text.getStyleClass().contains(style)) {
// Will not reset background, even though style is removed?
this.text.getStyleClass().remove(style);
}
}
// Apply reset style to clear background color
this.text.getStyleClass().add("clearStyle");
}
if (null != example) {
this.text.setText(example.getContent());
if (example.isImportant()) {
this.text.getStyleClass().add("styleImportant");
}
}
}
};
}
});
</code></pre>
<p>My style sheet:</p>
<pre><code>/** Keep black text color, when user selects row */
.table-row-cell:focused {
-fx-dark-text-color: #000000;
-fx-mid-text-color: #000000;
-fx-light-text-color: #000000;
}
/** Style to reset background color */
.clearStyle {

}
/** Style for important cells */
.styleImportant {
/** Red text color on any background */
-fx-dark-text-color: #FF0000;

WPF datagrid pasting
|
<p>I'm having trouble pasting from a csv into the wpf datagrid - I have followed the suggestions here</p>
<p><a href="https://docs.microsoft.com/en-us/archive/blogs/vinsibal/pasting-content-to-new-rows-on-the-wpf-datagrid" rel="nofollow noreferrer">Link</a></p>
<p>and the code exectues with no problem - however, it seems that all the new rows are created but only the first row gets populated with data. The data seems to be constantly overwritten so that the last item that is in the clipboard data is populated in the first row and all other rows are blank. I know this must be an index issue or something but I cannot track it down.</p>
<p>Also when I have a look at the objects in the grid's bindable collection none of them have any data in. Is there something in the OnPastingCellClipboardContent of the column that is going wrong (data conversion perhaps)?</p>
<p>Any ideas (see the code below)</p>
<pre><code>protected virtual void OnExecutedPaste(object sender, ExecutedRoutedEventArgs args)
{
// parse the clipboard data
List<string[]> rowData = ClipboardHelper.ParseClipboardData();
bool hasAddedNewRow = false;
// call OnPastingCellClipboardContent for each cell
int minRowIndex = Math.Max(Items.IndexOf(CurrentItem), 0);
int maxRowIndex = Items.Count - 1;
int minColumnDisplayIndex = (SelectionUnit != DataGridSelectionUnit.FullRow) ? Columns.IndexOf(CurrentColumn) : 0;
int maxColumnDisplayIndex = Columns.Count - 1;
int rowDataIndex = 0;
for (int i = minRowIndex; i <= maxRowIndex && rowDataIndex < rowData.Count; i++, rowDataIndex++)
{
if (CanUserAddRows && i == maxRowIndex)
{
// add a new row to be pasted to
ICollectionView cv = CollectionViewSource.GetDefaultView(Items);
IEditableCollectionView iecv = cv as IEditableCollectionView;
if (iecv != null)
{
hasAddedNewRow = true;
iecv.AddNew();
if (rowDataIndex + 1 < rowData.Count)
{
// still has more items to paste, update the maxRowIndex
maxRowIndex = Items.Count - 1;
}
}
}
else if (i == maxRowIndex)
{
continue;
}
int columnDataIndex = 0;
for (int j = minColumnDisplayIndex; j < maxColumnDisplayIndex && columnDataIndex < rowData[rowDataIndex].Length; j++, columnDataIndex++)
{
DataGridColumn column = ColumnFromDisplayIndex(j);
column.OnPastingCellClipboardContent(Items[i], rowData[rowDataIndex][columnDataIndex]);
}
}

<p>As mentioned <a href="https://spring.io/blog/2014/03/07/deploying-spring-boot-applications#comment-1317477696" rel="noreferrer">here</a>, I am having a heck of a time getting my small Spring-Boot project to deploy "correctly" to Glassfish. It runs fine using the embedded Tomcat, but once I try and move it into my organization's environment (Glassfish 3.1.2) I get some strange behavior.</p>
<p>Thinking it was my code, I reverted to the time-tested "Hello World"-approach and built a super-basic app following <a href="https://spring.io/blog/2014/03/07/deploying-spring-boot-applications" rel="noreferrer">this tutorial on Spring's blog</a>.</p>
<p>I did make a few very minor deviations as I went along but nothing that should have affected the app like this at all. </p>
<p>The only major deviation I made was that I found I could not exclude "spring-boot-starter-tomcat" from "spring-boot-starter-web" -- when I tried to that, I got 2 errors in the STS "Markers"-tab:</p>
<pre><code>The project was not built since its build path is incomplete. Cannot find the class file for javax.servlet.ServletContext. Fix the build path then try building this project
The type javax.servlet.ServletContext cannot be resolved. It is indirectly referenced from required .class files Application.java
</code></pre>
<p>If I cleaned the STS project, then ran Maven Clean, Update, Install the Install goal gave the following error:</p>
<pre><code>Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project test: Compilation failure [ERROR] /Users/brandon_utah/Utah Development/sts_workspaces/NidTools Rebooted/test/src/main/java/test/Application.java:[13,8] cannot access javax.servlet.ServletException [ERROR] class file for javax.servlet.ServletException not found
</code></pre>
<p>So what I did instead was include this dependency (which I found mentioned in several other SpringBoot resources):</p>
<pre><code><dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
</code></pre>
<p>In this deployed fine to the embedded Tomcat and it did deploy to my Glassfish (local install) -- but with a whole bunch (about a half-dozen) errors similar to this one:</p>
<pre><code>2014-04-03T16:23:48.156-0600|SEVERE: Class [ Lorg/springframework/jdbc/datasource/embedded/EmbeddedDatabase; ] not found. Error while loading [ class org.springframework.boot.autoconfigure.jdbc.EmbeddedDataSourceConfiguration ]
</code></pre>
<p>Most of them are SEVERE, but I am also getting a few with a WARNING:</p>
<pre><code>2014-04-04T06:57:35.921-0600|WARNING: Error in annotation processing: java.lang.NoClassDefFoundError: org/springframework/batch/core/configuration/annotation/BatchConfigurer
</code></pre>
<p>Except that I'm not referencing any of these missing classes anywhere in my project (other than what might be referenced by Spring Boot itself).</p>
<p>Also, the app doesn't quite work as expected. If I hit the RestController, I do get my page rendered as I expect -- but if I put any sort of System.out or Logger.log statement in the controller's method, that line of code seemingly never gets executed; by all appearances, it just gets skipped.</p>
<p>To demonstrate this problem, in my sample app's RestController I created a static counter. Then in the GET-/ method I increment that counter and System.out.println it's value. I also return the value as part of the Response.</p>
<p>And again, from a user's perspective, it seems to be working: the screen renders "Hello World" and in parentheses it shows the counter's value. I refresh the window, the counter increments. But nothing in the STS Console. And if I navigate to the Glassfish log for the app, nothing there either. Nothing. Nada. Zip. From what I can tell, something is mysteriously eating any attempt to log anything. </p>
<p>To add to the mystery, if I add a System.out to the SpringBootServletInitializer#configure(), that does make it to the Console. But if I declare a constructor in my RestController and include a System.out there, that one does not make it to the Console. For good measure, I even tried including a System.err in the constructor and a Logger.getAnonymousLogger.severe in the method; neither of those result in anything.</p>
<p>I should note that this also deploys and runs as expected using an external Tomcat.</p>
<p>I would very much appreciate any input, as it's not likely that I can convince my organization to deploy this to Tomcat nor use the embedded-Tomcat approach (due to politics and an overwhelming existing Glassfish environment).</p>

<p>I checked my permissions: </p>
<pre><code>lrwxrwxrwx 1 root 18 Oct 28 18:19 /usr/bin/python -> /usr/bin/python2.7
lrwxrwxrwx 1 root 24 Oct 28 18:26 /usr/bin/python2.7 -> /usr/local/bin/python2.7
lrwxrwxrwx 1 root 9 Oct 28 15:13 /usr/bin/python2 -> python2.6
-rwxr-xr-x 1 root 2613296 Apr 16 2010 /usr/bin/python2.6
</code></pre>
<p>I noticed I'd added an extra step, so I refactored it: </p>
<pre><code>llrwxrwxrwx 1 root 24 Oct 28 18:33 /usr/bin/python -> /usr/local/bin/python2.7
lrwxrwxrwx 1 root 9 Oct 28 15:13 /usr/bin/python2 -> python2.6
-rwxr-xr-x 1 root 2613296 Apr 16 2010 /usr/bin/python2.6
</code></pre>
<p>So now, Python2.7 should be the default version, but it still fails. </p>
<pre><code>$ sh setuptools-0.6c11-py2.7.egg --prefix=/usr/local/bin/python2.7

PHP foreach loop using one entry twice
|
<p>I'm just experimenting a little with PHP and PDO working with a MySQL database and I'm a little stumped as to why after getting the results, storing them correctly in a multi-dimensional array and looping through them it outputs one of the array data twice.</p>
<p>Essentially here's the query to grab the data:</p>
<pre><code>SELECT b.Price, b.ImgURL, m.Name, f.ID, f.Family, f.URL FROM Products AS b INNER JOIN Manufacturers AS m ON m.ID = b.Manufacturer INNER JOIN FamilyLookUp AS l ON l.Product = b.ID INNER JOIN Families AS f ON f.ID = l.Family GROUP BY f.ID ORDER BY b.Price ASC
</code></pre>
<p>I was hoping with this to get 1 row returned for each Family, which it works correctly both in the PHPMyAdmin query and also when print_r() the results.</p>
<p>I then store in:</p>
<pre><code>$families[] = array('ID' => $f['ID'], 'Manufacturer' => $f['Name'], 'Family' => $f['Family'], 'URL' => $f['URL'], 'IMG' => $f['ImgURL'], 'Price' => $f['Price'], 'ScentCount' => 0);
</code></pre>
<p>Which also works correctly when doing a print_r() and when just looping through with a foreach loop echoing out the ID for each entry it returns 1234567 (all 7 Family IDs)</p>
<p>Then I run another query:</p>
<pre><code>try{
$sqlCmd = "SELECT COUNT(*) FROM FamilyLookUp WHERE Family=:fID";
$s = $pdo->prepare($sqlCmd);
foreach($families as &$fam){
$s->bindValue(':fID', $fam['ID']);
$s->execute();
$fam['ScentCount'] = $s->fetchColumn();
}
}
</code></pre>
<p>This also gets the correct counts and properly stores them in the array for the number of items within each family. So all good up to now.</p>
<p>The problem occurs when I:</p>
<pre><code>foreach($families as $fam):
?>
<div class="product-listing">
<?php echo $fam['ID']; ?>
<div class="product-listing-image">
<a href="<?php echo $fam['URL']; ?>"><img alt="" src="<?php echo $fam['IMG']; ?>"></a>
</div>
<div class="product-listing-details">
<a href="<?php echo $fam['URL']; ?>"><h3><?php echo strtoupper($fam['Manufacturer']); if($fam['Family'] != ""){ echo strtoupper(' - ' . $fam['Family']);} ?></h3></a>
<?php if($fam['ScentCount'] == 1): ?>
<span class="product-scent-count"><?php echo $fam['ScentCount']; ?> Scent</span>
<span class="product-price-value">£<?php echo $fam['Price']/100; ?></span>
<?php elseif($fam['ScentCount']>1): ?>
<span class="product-scent-count"><?php echo $fam['ScentCount']; ?> Scents</span>
<span class="product-price-value">From £<?php echo $fam['Price']/100; ?></span>
<?php endif;?>
</div>
</div>
<?php
endforeach;
?>
</code></pre>
<p>After doing this, it outputs correctly for the first 6 families of data, but for some reason it outputs a duplicate of the 6th instead of the actual 7th. When doing a print_r of all the data in the line before the start of the foreach loop, it returns all the correct data and yet within the foreach loop there becomes 1 duplicate array in the place of the 7th originally correct array.</p>
<p>Any advice would be awesome. </p>
<p>Edit for Kohloth's answer(the print_r followed directly by foreach vardump):</p>
<pre><code>Array
(
[0] => Array
(
[ID] => 1
)
[1] => Array
(
[ID] => 7
)
[2] => Array
(
[ID] => 2

task.Wait throwing an exception
|
<p>Largely as a follow-up to this question <a href="https://stackoverflow.com/questions/4380732/test-driven-asynch-tasks">test driven asynch tasks</a> I have come up with some code that works if I don't have the task wait, but fails if I do.</p>
<p>Can anyone explain why?</p>
<p><strong>Exception:</strong></p>
<p>I get this error when the code hits the constructor of a utility class written by Stephen Cleary on his blog <a href="http://nitoprograms.blogspot.com/2010/06/reporting-progress-from-tasks.html" rel="nofollow noreferrer">here</a></p>
<pre><code>public ProgressReporter()
{
_scheduler = TaskScheduler.FromCurrentSynchronizationContext();

}
</code></pre>
<p><strong>The SuT:</strong></p>
<pre><code>private void _startBackgroundTask(bool causeError)
{
_cancellationTokenSource = new CancellationTokenSource();
var cancellationToken = _cancellationTokenSource.Token;
_progressReporter = new ProgressReporter();
var task = Task.Factory.StartNew(() =>

// Report progress of the work.
_progressReporter.ReportProgress(
() =>

// Note: code passed to "ReportProgress" can access UI elements freely.
_currentProgress = i;
});

// After all that work, cause the error if requested.

else if (task.IsCanceled)

</code></pre>
<p><strong>Just to be clear:</strong> If I comment out task.Wait, that test actually succeeds. Why is that?</p>
<p><strong>Extra points:</strong></p>
<p>I know this is technically another question but it seems a shame to repeat all of this, so:</p>
<p>Why did my MockSynchContext not throw an exception on TaskScheduler.FromCurrentSynchronizationContext() in my test but did in the second task? More importantly, is there a way to pass the context along so I can do the test properly?</p>

Using the same controller on different elements to refer to the same object
|
<p>I figured if I slapped <code>ng-controller="GeneralInfoCtrl"</code> on multiple elements in my DOM they would share the same <code>$scope</code> (or least two-way binding isn't working).</p>
<p>The reason I want to do this is because I have different read-only views with associated modal dialogs in very different parts of the HTML and they don't share a common ancestor (aside from <code><body></code> and <code><html></code>).</p>
<p>Is there a way to make both controllers refer to the same object/make data binding work between them?</p>
<hr>
<p>Here's some code for those who insist on seeing markup, <em>written in <strong>Jade</em></strong>:</p>
<pre><code> .client-box(ng-controller="GeneralInfoCtrl")
.box-header
.box-title
h5 General Information
.box-buttons
button.btn.btn-small(data-target='#editGeneralInfo', data-toggle='modal', data-backdrop='static') <i class="icon-pencil"></i> Edit
.box-body
table.table.table-tight.table-key-value
tr
th Name
td {{client.fullName()}}
tr
th Also Known As
td {{client.aka}}
tr
th Birth Date
td {{client.birthDate|date:'mediumDate'}}
...
#editGeneralInfo.modal.hide.fade(ng-controller="GeneralInfoCtrl")
.modal-header
button.close(type='button', data-dismiss='modal') &times;
h3 Edit General Information
.modal-body
form.form-horizontal.form-condensed
.control-group
label.control-label First Name
.controls
input(type='text', placeholder='First Name', ng-model='client.firstName')
.control-group
label.control-label Last Name
.controls
input(type='text', placeholder='Last Name', ng-model='client.lastName')
.control-group
label.control-label Also Known As
.controls
input(type='text', placeholder='AKA', ng-model='client.aka')
.control-group
label.control-label Birth Date
.controls
input(type='text', placeholder='MM/DD/YYYY', ng-model='client.birthDate')
...
</code></pre>
<p>And my controller:</p>
<pre><code>function GeneralInfoCtrl($scope) {
$scope.client = {
firstName: 'Charlie',
lastName: 'Brown',
birthDate: new Date(2009, 12, 15),
...
}
}

Symfony ArrayCollection vs PersistentCollection

<p>As I understood when you query database by repository you get PersistentCollection and when your working with your entities you get ArrayCollection.</p>
<p>so consider I have one to many self referencing relation for my user entity.</p>
<p>and in my user entity I have a setChildren method which get ArrayCollection of users as argument .</p>

Android "No content provider found or permission revoke" with android 4
|
<p>I have an android application that works perfectly on android 2-2 and 2-3. But when i try to install the application on android 4-0 or 4-2-2 i twice get the following error:</p>
<p>No content provider found for permission revoke: file:///data/local/tmp/myapp.apk</p>
<p>I found out that others had a similar problem and i tried the solutions given in the following links:</p>
<p><a href="https://stackoverflow.com/questions/8639873/cannot-install-apk-on-android-device-through-eclipse/8646393#8646393">Cannot install APK on Android device through Eclipse</a>
for this one i have to say that my device is not rooted. i try to run my app on a emulator.</p>
<p><a href="https://stackoverflow.com/questions/9532653/android-4-0-3-emulator-install-fails-with-permission-revoke/9532683#9532683">Android 4.0.3 emulator: install fails with "permission revoke"</a></p>
<p><a href="https://stackoverflow.com/questions/11073358/android-error-message-on-install-no-content-provider-found">Android error message on install "no content provider found"</a>
here i tried another phone for the emulator. originally i used the galaxy nexus but i also tried with nexus 7</p>
<p><a href="https://stackoverflow.com/questions/11550798/android-no-content-provider-found-for-permission-revoke">Android "No content provider found for permission revoke"</a>
last but not least i tried to add the main action to the "androidmanifest.xml" i'm not sure if i did it the right way here is the manifest:</p>
<pre><code><manifest xmlns:android="http://schemas.android.com/apk/res/android"

android:versionName="1.0" >

<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</code></pre>
<p></p>
<p>Is there still something wrong with my manifest.xml file or do you have another idea why i can run this application on android 2 but not on 4?</p>

Calculate the accuracy every epoch in PyTorch
|
<p>I am working on a Neural Network problem, to classify data as 1 or 0. I am using Binary cross entropy loss to do this. The loss is fine, however, the accuracy is very low and isn't improving. I am assuming I did a mistake in the accuracy calculation. After every epoch, I am calculating the correct predictions after thresholding the output, and dividing that number by the total number of the dataset. Is there any thing wrong I did in the accuracy calculation? And why isn't it improving, but getting more worse?
This is my code:</p>
<pre class="lang-py prettyprint-override"><code>net = Model()
criterion = torch.nn.BCELoss(size_average=True)
optimizer = torch.optim.SGD(net.parameters(), lr=0.1)
num_epochs = 100
for epoch in range(num_epochs):
for i, (inputs,labels) in enumerate (train_loader):
inputs = Variable(inputs.float())
labels = Variable(labels.float())
output = net(inputs)
optimizer.zero_grad()
loss = criterion(output, labels)
loss.backward()
optimizer.step()
#Accuracy
output = (output>0.5).float()
correct = (output == labels).float().sum()
print("Epoch {}/{}, Loss: {:.3f}, Accuracy: {:.3f}".format(epoch+1,num_epochs, loss.data[0], correct/x.shape[0]))
</code></pre>
<p>And this is the strange output I get:</p>
<pre><code>Epoch 1/100, Loss: 0.389, Accuracy: 0.035

How to fix "Failed to obtain JDBC Connection" datasource error in my java application
|
<p>I have a little training project running under Java Spring MVC and using MySQL on WAMP Server), it was working but i cloned it and had to reinstall database (restored from a dump) and Wamp64 also, but now my java application cannot connect and i get different errors.</p>
<p>In IntelliJ IDEA when i test the connection to the database, the connection is successfull, even in phpmyadmin, but not when i launch my application.</p>
<p><code>jdbc:mysql://localhost:3306/library?serverTimezone=UTC</code> (i had to use server timezone to fixe timezone error)</p>
<p>It's looking like my java app doesn't use the good datasource configuration, and instead use the old one but i can't figure out why.</p>
<p>My application is using SOAP protocol to connect to my webservices.</p>
<p>The main error is a javaNullPointer exception on the line where i try to get the user from database trough an input form.</p>
<p>The other error is (when i go in debug mode):</p>
<blockquote>
<p>Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: Accès refusé pour l'utilisateur: 'root'@'@localhost' (mot de passe: OUI) error.</p>
</blockquote>
<p>This project was cloned from an old project. I suppose there is somewhere an old datasource used by the application.</p>
<p>It looks like my application uses old login settings for mysql (login: root, password: password). I recently changed the login information to my database, to an "admin_library" login that has all the privileges and a password. </p>
<p>I invalidated and restarted the IntelliJ cache, made an "mvn clean install", but when I run my two tomcat servers (one for the webservice, another one for the soap webserviceclient), my login screen appears but I have a null point exception (apparently due to a database connection problem.</p>
<p>Here is my configuration:</p>

How to handle errors in fetch() responses with Redux Thunk?
|
<p>I'm making API requests using isomorphic fetch, and using Redux to handle my app's state.</p>
<p>I want to handle both internet connection loss errors, and API errors, by firing off Redux actions.</p>
<p>I have the following (work-in-progress / bad) code, but can't figure out the correct way to fire the Redux actions (rather than just throw an error and stop everything) :</p>
<pre><code>export function createPost(data = {}) {
return dispatch => {
dispatch(requestCreatePost(data))
return fetch(API_URL + data.type, {
credentials: 'same-origin',
method: 'post',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
'X-WP-Nonce': API.nonce
},
body: JSON.stringify(Object.assign({}, data, {status: 'publish'}))
}).catch((err) => {
//HANDLE WHEN HTTP ISN'T EVEN WORKING
return dispatch => Promise.all([
dispatch({type: PRE_FETCH_RESOURCES_FAIL, errorType: 'fatal', message:'Error fetching resources', id: h.uniqueId()}),
dispatch({type: PRE_CREATE_API_ENTITY_ERROR, errorType: 'fatal', id: h.uniqueId(), message: 'Entity error before creating'})
])
}).then((req) => {
//HANDLE RESPONSES THAT CONSTITUTE AN ERROR (VIA THEIR HTTP STATUS CODE)
console.log(req);
if (!req || req.status >= 400) {
return dispatch => Promise.all([
dispatch({type: FETCH_RESOURCES_FAIL, errorType: 'warning', message:'Error after fetching resources', id: h.uniqueId()}),
dispatch({type: CREATE_API_ENTITY_ERROR, errorType: 'warning', id: h.uniqueId(), message: 'Entity error whilst creating'})
])
}
else {
return req.json()
}
}).then((json) => {
var returnData = Object.assign({},json,{
type: data.type
});
dispatch(receiveCreatePost(returnData))
})
}
}
</code></pre>
<p>If I intionally disable the internet connection, in the JS Console, when I log via console.log() (as above), it's outputting this:
<code>
POST http://example.com/post net::ERR_INTERNET_DISCONNECTED(anonymous function)
(dispatch) {
return Promise.all([dispatch({ type: PRE_FETCH_RESOURCES_FAIL, errorType: 'fatal', message: 'Error fetching resources', id: _CBUtils2.default.uniqueId() }), dispatch({ type:…
cb_app_scripts.js?ver=1.0.0:27976 Uncaught (in promise) TypeError: req.json is not a function(…)
</code></p>
<p>Forgive me if this is entirely wrong, but I don't want to do anything but fire off two Redux Actions when there is an error (a general error, and one specific to the action we were performing when the error occurred).</p>
<p>Is what I'm trying to achieve even possible?</p>
<p>It seems that (via my logging to console) the 'then' part of the script is still being executed (as the contents of it are my 'catch' dispatch functions)..</p>

Jquery: Add class to every second visible element
|
<p>I'm trying to create a dynamic portfolio gallery where you can hide show items by clicking categories. Everything works apart from adding a class to elements hidden/showing when categories are clicked.</p>
<p>I currently have:</p>
<pre><code>$(document).ready(function() {
$('ul.filter a').click(function() {
$(this).css('outline','none');
$('ul.filter .current').removeClass('current');
$(this).parent().addClass('current');
var filterVal = $(this).text().toLowerCase().replace(' ','-');
if(filterVal == 'all') {
$('div.portfolio .hidden').fadeIn('slow').removeClass('hidden');
} else {
$('div.portfolio').each(function() {
if(!$(this).hasClass(filterVal)) {
$(this).fadeOut('normal').addClass('hidden');
} else {
$(this).fadeIn('slow').removeClass('hidden').addClass("show");
$('.portfolio:visible').each(function (i) {
if (i % 2 == 0) $(this).addClass("last"); // This is the part that doesn't seem to work
});
}
});
}
return false;
});
});
</code></pre>
<p>It's this part of the code that seems to have the problem:</p>
<pre><code>$('.portfolio:visible').each(function (i) {
if (i % 2 == 0) $(this).addClass("last"); // This is the part that doesn't seem to work
});
</code></pre>
<p>Basically, I'm looking to add the class .last to every second "visible" item in my portfolio list.</p>
<p>Anyone?</p>

Content Security Policy directive: “frame-ancestors” missing but there?
|
<p>I am working on a nodejs electron app, in my index.html I have a "Content-Security-Policy" that looks like this </p>
<pre><code><!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Security-Policy"
content="
default-src 'self' https://*.mydomain.tld;
script-src 'self' https://*.mydomain.tld;
style-src 'self' https://*.mydomain.tld;
img-src 'self' https://*.mydomain.tld;
font-src 'self' https://*.mydomain.tld;
connect-src 'self' https://*.mydomain.tld;
media-src 'self' https://*.mydomain.tld;
object-src 'self' https://*.mydomain.tld;
child-src 'self' https://*.mydomain.tld;
frame-ancestors 'self' https://*.mydomain.tld;
frame-src 'self' https://*.mydomain.tld;
worker-src 'self' https://*.mydomain.tld;
form-action 'self' https://*.mydomain.tld;
block-all-mixed-content;
">
</code></pre>
<p>When I run the app it works perfectly fine all assets are loaded just fine but in the console I get the following error</p>
<blockquote>
<p>Content Security Policies delivered via a element may not
contain the frame-ancestors directive. index.html: 4</p>
</blockquote>
<p>I been trying to get rid of the error and looking for what maybe causing it but can't find anything, all to me appears to be correct yet I still receive the error, I also thought that the error maybe caused by the server @https://*.mydomain.tld so I tried this</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Security-Policy"
content="
default-src 'self';
script-src 'self';
style-src 'self';
img-src 'self';
font-src 'self';
connect-src 'self';
media-src 'self';
object-src 'self';
child-src 'self';
frame-ancestors 'self';
frame-src 'self';
worker-src 'self';
form-action 'self';
block-all-mixed-content;
">
</code></pre>
<p>Which caused the exact same error, I could just ignore the error completely as the app does work correctly and the error does not seem to be causing any issues however if someone has any idea what maybe wrong I would really appreciate it.</p>
<p><strong>Edit:</strong> When I removed the frame-ancestors leaving the tag looking like this</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Security-Policy"
content="
default-src 'self' https://*.mydomain.tld;
script-src 'self' https://*.mydomain.tld;

worker-src 'self' https://*.mydomain.tld;
form-action 'self' https://*.mydomain.tld;
block-all-mixed-content;
">
</code></pre>
<p>The error went away, am I not supposed to add that?</p>

Extract Exchange 2007 Public Calendar Appointments using Exchange Web Services API
|
<p>We have a public calendar for our company set up in an Exchange 2007 Public Folder. I am able to retrieve my personal calendar appointments for the current day using the code below. I have searched high and low online and I cannot find one example of someone retrieving calendar information from a Public Folder calendar.</p>
<p>It seems like it should be doable, but I cannot for the life of me get it working. How can I modify the code below to access the calendar? I am not interested in creating any appointments through asp.net, just retrieving a simple list. I am open to any other suggestions as well. Thanks.</p>
<p><strong>ADDED BOUNTY</strong><br>
- I can't be the only person that ever needed to do this. Let's get this problem solved for future generations.</p>
<p><strong>UPDATED AGAIN DUE TO IGNORANCE</strong><br>
- I failed to mention that the project I am working on is .NET 2.0 (very important don't you think?).</p>
<p><strong>* ADDED MY CODE SOLUTION BELOW *</strong><br>
- I have replaced my original code example with the code that ended up working. Many thanks to Oleg for providing the code to find the public folder, which was the hardest part.. I have modified the code using the example from here <a href="http://msexchangeteam.com/archive/2009/04/21/451126.aspx" rel="noreferrer">http://msexchangeteam.com/archive/2009/04/21/451126.aspx</a> to use the simpler FindAppointments method.</p>
<p>This simple example returns an html string with the appointments, but you can use it as a base to customize as needed. You can see our back and forth under his answer below.</p>
<pre><code>using System;
using Microsoft.Exchange.WebServices.Data;

Call a javafx fxml controller method from another class to update a tableview
|
<p>I am trying to update a javafx tableview defined in my fxml controller by calling a particular method FXMLDocumentController.onAddSystemMessage() from another application utility class method GlobalConfig.addSystemMessage(). </p>
<p>Here is my main Application class where i load the fxml:</p>
<pre><code>public class Main extends Application {
...
public static void main(String[] args) throws IOException {
Application.launch(args);
}
...
@Override
public void start(Stage primaryStage) throws IOException {
AnchorPane page = (AnchorPane) FXMLLoader.load(Main.class.getResource("FXMLDocument.fxml"));
Scene scene = new Scene(page, initWidth, initHeight);
primaryStage.setScene(scene);
currentPane(scene, page);
primaryStage.show();
}
</code></pre>
<p>So here are some parts of FXMLDocumentController:</p>
<pre><code>public class FXMLDocumentController implements Initializable {
...
@FXML

Using Log4J 1.*, how can I write two packages to two separate files?
|
<p>I have the following two packages:</p>
<p>com.mycorp.project.first<br>
com.mycorp.project.second</p>
<p>I'd like to configure Log4J (SLF4J) to write the logs from one package to one file, and from the other package to a second file. I do not want them to be mixed in together. </p>
<p>To be clear, this is one project/one process running.</p>
<p>I've tried filtering and with loggers but they seem to be ignored by log4j. Both files are always identical.</p>

Queuing Actions in Redux
|
<p>I've currently got a situation whereby I need Redux Actions to be run consecutively. I've taken a look at various middlewares, such a redux-promise, which seem to be fine <em>if you know what the successive actions are at the point of the root (for lack of a better term) action being triggered</em>.</p>
<p>Essentially, I'd like to maintain a queue of actions that can be added to at any point. Each object has an instance of this queue in its state and dependent actions can be enqueued, processed and dequeued accordingly. I have an implementation, but in doing so I'm accessing state in my action creators, which feels like an anti-pattern.</p>
<p>I'll try and give some context on use case and implementation.</p>
<h2>Use Case</h2>
<p>Suppose you want to create some lists and persist them on a server. On list creation, the server responds with an id for that list, which is used in subsequent API end points pertaining to the list:</p>
<pre><code>http://my.api.com/v1.0/lists/ // POST returns some id
http://my.api.com/v1.0/lists/<id>/items // API end points include id
</code></pre>
<p>Imagine that the client wants to perform optimistic updates on these API points, to enhance UX - nobody likes looking at spinners. So when you create a list, your new list instantly appears, with an option at add items:</p>
<pre><code>+-------------+----------+
| List Name | Actions |
+-------------+----------+
| My New List | Add Item |
+-------------+----------+
</code></pre>
<p>Suppose that someone attempts to add an item before the response from the initial create call has made it back. The items API is dependent on the id, so we know we can't call it until we have that data. However, we might want to optimistically show the new item and enqueue a call to the items API so that it triggers once the create call is done.</p>
<h2>A Potential Solution</h2>
<p>The method I'm using to get around this currently is by giving each list an action queue - that is, a list of Redux actions that will be triggered in succession.</p>
<p>The reducer functionality for a list creation might look something like this:</p>
<pre><code>case ADD_LIST:
return {
id: undefined, // To be filled on server response
name: action.payload.name,
actionQueue: []
}
</code></pre>
<p>Then, in an action creator, we'd enqueue an action instead of directly triggering it:</p>
<pre><code>export const createListItem = (name) => {
return (dispatch) => {
dispatch(addList(name)); // Optimistic action
dispatch(enqueueListAction(name, backendCreateListAction(name));
}
}
</code></pre>
<p>For brevity, assume the backendCreateListAction function calls a fetch API, which dispatches messages to dequeue from the list on success/failure.</p>
<h2>The Problem</h2>
<p>What worries me here is the implementation of the enqueueListAction method. This is where I'm accessing state to govern the advancement of the queue. It looks something like this (ignore this matching on name - this actually uses a clientId in reality, but I'm trying to keep the example simple):</p>
<pre><code>const enqueueListAction = (name, asyncAction) => {
return (dispatch, getState) => {
const state = getState();
dispatch(enqueue(name, asyncAction));{
const thisList = state.lists.find((l) => {
return l.name == name;
});
// If there's nothing in the queue then process immediately
if (thisList.actionQueue.length === 0) {
asyncAction(dispatch);
}
}
}
</code></pre>
<p>Here, assume that the enqueue method returns a plain action that inserts an async action into the lists actionQueue. </p>
<p>The whole thing feels a bit against the grain, but I'm not sure if there's another way to go with it. Additionally, since I need to dispatch in my asyncActions, I need to pass the dispatch method down to them.</p>
<p>There is similar code in the method to dequeue from the list, which triggers the next action should one exist:</p>
<pre><code>const dequeueListAction = (name) => {
return (dispatch, getState) => {
dispatch(dequeue(name));
const state = getState();
const thisList = state.lists.find((l) => {
return l.name === name;
});
// Process next action if exists.
if (thisList.actionQueue.length > 0) {
thisList.actionQueue[0].asyncAction(dispatch);
}
}
</code></pre>
<p>Generally speaking, I can live with this, but I'm concerned that it's an anti-pattern and there might be a more concise, idiomatic way of doing this in Redux.</p>
<p>Any help is appreciated.</p>

<p>I am sharing my 2 file's code.for insert username and passwords and to retrieve data. My scenario is something different. if username :

How to remove unwanted spaces at the right of CheckBox?
|
<p>I am working on a custom list view. I want to show a <code>CheckBox</code> at the custom view. There is no text for the <code>CheckBox</code>. I found it always have some spaces at the right of the <code>CheckBox</code>.</p>
<p>Here is my layout xml file:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:orientation="horizontal" android:background="#fa9654"
android:paddingTop="65dp" android:paddingBottom="65dp">
<TextView android:id="@+id/bus_route_list_item_num"
android:layout_height="wrap_content" android:layout_width="0dip"
android:gravity="center" android:layout_gravity="center_vertical|center_horizontal"
android:layout_weight="0.15"></TextView>
<TextView android:id="@+id/bus_route_list_item_station"
android:layout_height="wrap_content" android:layout_width="0dip"
android:gravity="left" android:layout_gravity="center_vertical|center_horizontal"
android:layout_weight=".5"></TextView>
<TextView android:id="@+id/bus_route_list_item_fee"
android:layout_height="wrap_content" android:layout_width="0dip"
android:gravity="center" android:layout_gravity="center_vertical|center_horizontal"
android:layout_weight=".15"></TextView>
<CheckBox android:id="@+id/bus_route_list_item_reminder" android:layout_height="wrap_content"
android:layout_width="0dip" android:layout_weight=".20" android:gravity="center"
android:layout_gravity="center" android:paddingRight="0dp" android:paddingLeft="0dp"
android:paddingTop="0dp" android:paddingBottom="0dp" android:background="#0066ff"
android:text=""
/>
</LinearLayout>
</code></pre>
<p>The result looks like:</p>
<p><img src="https://i.stack.imgur.com/RdlPe.jpg" alt="Checkbox result" /></p>
<p>As you can see there are some space at the right of the checkbox. What I want is put the checkbox at the middle of the blue area.</p>
<p>Is it possible to remove the unwanted space? thanks</p>

Facebook not able to scrape my url
|
<p>I have the HTML structure for my page as given below. I have added all the meta og tags, but still facebook is not able to scrape any info from my site. </p>
<pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Frameset//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-frameset.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml">

</code></pre>
<p>When I input the URL in facebook debugger(https://developers.facebook.com/tools/debug), I get the following messages:</p>
<pre><code>Scrape Information

Inferred Property The 'og:url' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property The 'og:title' property should be explicitly provided, even if a value can be inferred from other tags.
</code></pre>
<p>Why is facebook not reading the meta tags info? The page is accessible and not hidden behind login etc.</p>
<p><strong>UPDATE</strong></p>
<p>Ok I did bit of debugging and this is what I found. I have htaccess rule set in my directory- I am using PHP Codeigniter framework and have htaccess rule to remove index.php from the url. </p>
<p>So, when I feed the url to facebook debugger(https://developers.facebook.com/tools/debug) without index.php, facebook shows a 404, but when I feed url with index.php, it is able to parse my page. </p>
<p>Now how do I make facebook scrape content when the url doesn't have index.php?</p>
<p>This is my htaccess rule:</p>
<pre><code><IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
#Removes access to the system folder by users.
#Additionally this will allow you to create a System.php controller,
#previously this would not have been possible.
