Type mismatch: inferred type is LoginActivity but LifecycleOwner was expected
|
<p>I am playing with the preview version of <code>AndroidStudio - 3.4 Canary 9</code>.</p>
<p>I selected the default login activity option from <code>Configure your project</code> window and provided, selected below options:</p>
<p><a href="https://i.stack.imgur.com/mYobT.png" rel="noreferrer"><img src="https://i.stack.imgur.com/mYobT.png" alt="Configure your project"></a></p>
<p>No error reported on Gradle sync, however on build compilation it produces following error:</p>
<pre><code>Type mismatch: inferred type is LoginActivity but LifecycleOwner was expected
</code></pre>
<p>Here is the code snippet on which it is showing the error:</p>
<pre><code>// Type mismatch at this@LoginActivity, required LifeCycleOwner, found - LoginActivity
loginViewModel.loginFormState.observe(this@LoginActivity, Observer {
val loginState = it ?: return@Observer
// disable login button unless both username / password is valid
login.isEnabled = loginState.isDataValid
if (loginState.usernameError != null) {
username.error = getString(loginState.usernameError)
}
if (loginState.passwordError != null) {
password.error = getString(loginState.passwordError)
}
})

Mapping coordinates from 3D perspective projection to 2D orthographic projection in OpenGL in C++

<p>I have written a simple openGL program in C++. This program draws a sphere in 3D perspective projection and tries to draw a line joining the center of the sphere to the current cursor position in 2D orthographic projection.

error: expected declaration before } token (when trying to compile)
|
<p>I'm having a problem. I have the template and implementation for a stack in files <strong>stack.h</strong> and <strong>stack.hpp</strong>. Then I have an <strong>in2out.cpp</strong> file that converts infix expressions to outfix expressions and evaluates them. At the beginning of in2out.cpp I "#include stack.h". And inside <strong>stack.h (which is my interface)</strong> I "#include stack.hpp" <strong>(stack.hpp is my implementation)</strong>. I know this is weird but it's the way I'm required to do it.</p>
<p>Anyways, my problem is, when I'm trying to compile these 3 files together. I get only 1 error which is in stack.h (my interface, listed below). The error is: </p>

How to pass multiple arguments to a smarty function?
|
<p>I've a following code snippet from smarty template:</p>
<pre><code><div class="pagination">
{pagination_link_01 values=$pagination_links}
</div>
</code></pre>
<p>The following is the function body:</p>
<pre><code><?php
function smarty_function_pagination_link_01($params, &$smarty)
{
if ( !is_array($params['values']) )
{
return "is not array";
}
if ( 0 == count($params['values']) )
{
return "Empty Array";
}
if ( empty($params['values']['current_page']) )
{
return "Invalid Request";
}
$values = $params['values'];
//Seperator Used Betwinn Pagination Links
$seprator = empty( $params['seperator'] ) ? "&nbsp;&nbsp;" : $params['seperator'];
//Class Name For Links
$extra = empty( $params['extra'] ) ? "" : $params['extra'];
$current_page = (int)$values['current_page'];
if ( !empty($values['first']) )
{
//$ret[] = "<a $extra href='{$values['first']}' >&lt;First</a>";
}
if ( !empty($values['previous'] ) )
{
$ret[] = "<a $extra href='{$values['previous']}' class='prev active'><span></span></a>";
}
$ret[] = "<ul>";
foreach( $values as $k => $v )
{
if( is_numeric( $k ) )
{
if ( $k == $current_page)
{
$ret[] = "<li><a $extra class='active'>$k</a></li>";
}
else
{
$ret[] = "<li><a $extra href='$v'>$k </a></li>";
}
}
}
if ( !empty($values['next'] ) )
{
$ret[] = "</ul><a $extra href='{$values['next']}' class='next active'><span></span></a>";
}
if ( !empty($values['last'] ) )
{
//$ret[] = "<a $extra href='{$values['last']}' >Last&gt;</a>";
}
//$str_ret = $first . $previous . $str_ret . $next . $last;
if ( $ret )
{
return implode( $seprator, $ret );
}
}
?>
</code></pre>
<p>If I print <code>$params</code> I'm getting the values I passed by means of an array <code>$pagination_links</code>. Similarly I want to add one more argument named <code>$total_pages</code> to the above function call and use it in the function body. I tried many ways but it couldn't happen. Can anyone please guide me in this regard please. Thanks in advance.</p>

Performance of FirstOrDefault()
|
<p>Looking at a section of the webapp I work on today with a performance profiler. I thought that a Union was causing some delays, but found other surprising results instead.</p>
<p>One of the causes of slowdown appeared to be FirstOrDefault.</p>
<p>It was a very simple LINQ query that looked like this:</p>
<pre><code>foreach(Report r in reports)
IDTOStudy study = studies.FirstOrDefault(s => s.StudyID == r.StudyID);
</code></pre>
<p>I created a small method to duplicate the behaviour I figured FirstOrDefault was doing.</p>
<pre><code>private IDTOStudy GetMatchingStudy(Report report, IList<IDTOStudy> studies)
{
foreach (var study in studies)
if (study.StudyID == report.StudyID)
return study;
return null;
}
</code></pre>
<p>This method replaced the FirstOrDefault to look like this:</p>
<pre><code>foreach(Report r in reports)
IDTOStudy study = GetMatchingStudy(r, studies);
</code></pre>
<p>Looking at the new code running with the performance profiler showed <code>FirstOrDefault</code> to take twice as long to complete as my new method. This was a shock to see.</p>
<p>I must be doing something incorrect with the <code>FirstOrDefault()</code> query. What is it? </p>
<p>Does <code>FirstOrDefault()</code> complete the entire query and then take the first element? </p>
<p>How can I speed this up and use <code>FirstOrDefault()</code>?</p>
<p>Edit 1:</p>
<p>One additional point I noticed is that the profiler says I'm maxing out my CPU on both of these implementations. That's also something I don't care for and didn't expect. The additional method I added didn't reduce that spike, just cut its duration in half.</p>
<p>Edit 3:</p>
<p>Putting the studies into a dictionary has improved the run time tremendously. It's definitely going to be how the committed code looks. Doesn't answer the question on FirstOrDefault though.</p>
<p>Edit 2:</p>
<p>Here's the sample code requested in a simple console app. My run still shows that in most cases FirstOrDefault takes longer.</p>
<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Reactive.Linq;
using System.Reactive.Concurrency;
using System.Diagnostics;
namespace TestCode
{
public class Program
{
public List<IntHolder> list;
public static void Main(string[] args)
{
var prog = new Program();
prog.list = new List<IntHolder>();
prog.Add50000Items();
prog.list.Add(new IntHolder() { Num = 12345 });
prog.Add50000Items();
var stopwatch = new Stopwatch();
stopwatch.Start();
prog.list.FirstOrDefault(n => n.Num == 12345);
stopwatch.Stop();
Console.WriteLine("First run took: " + stopwatch.ElapsedTicks);
var lookingFor = new IntHolder() { Num = 12345 };
stopwatch.Reset();
stopwatch.Start();
prog.GetMatching(lookingFor);
stopwatch.Stop();
Console.WriteLine("Second run took: " + stopwatch.ElapsedTicks);
Console.ReadLine();
}
public void Add50000Items()
{
var rand = new Random();
for (int i = 0; i < 50000; i++)
list.Add(new IntHolder() { Num = rand.Next(100000) });
}
public IntHolder GetMatching(IntHolder num)
{
foreach (var number in list)
if (number.Num == num.Num)
return number;
return null;
}
}

public int Num { get; set; }
}
}

ASP.Net MVC switching Cultures after compile for initial load
|
<p>I have a hybrid ASP.Net web forms/MVC app. On one of the MVC "pages"/views, I have it render a bunch of dates using the ToShortDateString() and ToLongDateString(). These work correctly most of the time, but the first time I load the view after compiling the app, they are formatted incorrectly.</p>
<p>I traced this down and checked the current thread's culture. For 99% of the time it's en-US, but on the first load of the MVC view after compiling it is set to en-GB. If I reload the page immediately after that, it's back to en-US.</p>
<p>I have tried setting the culture and uiculture in the web.config file to en-US to force it to be correct, but no luck.</p>
<p>Anyone have any ideas on this one? Bug in MVC?</p>
<p>Edit (additional code and attempts):
Even if I go completely overboard and include this in the base class of the view</p>
<pre><code>public class DNViewPage<T> : ViewPage<T> where T : class
{
protected override void OnInit(EventArgs e) {
base.OnInit(e);
CultureInfo cultureInfo = new CultureInfo("en-US");
this.Culture = "en-US";
this.UICulture = "en-US";
Thread.CurrentThread.CurrentUICulture = cultureInfo;
Thread.CurrentThread.CurrentCulture = cultureInfo;
}
protected void Page_Load(object sender, EventArgs e) {
CultureInfo cultureInfo = new CultureInfo("en-US");
this.Culture = "en-US";
this.UICulture = "en-US";
Thread.CurrentThread.CurrentUICulture = cultureInfo;
Thread.CurrentThread.CurrentCulture = cultureInfo;
}
protected override void InitializeCulture() {
CultureInfo cultureInfo = new CultureInfo("en-US");
this.Culture = "en-US";
this.UICulture = "en-US";
Thread.CurrentThread.CurrentUICulture = cultureInfo;
Thread.CurrentThread.CurrentCulture = cultureInfo;
base.InitializeCulture();
}
}
</code></pre>
<p>and include this in the web.config</p>
<pre><code><globalization requestEncoding="utf-8" responseEncoding="utf-8" uiCulture="en-US" culture="en-US"/>
</code></pre>
<p>and this in the header of the .aspx file</p>
<pre><code><%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Culture="en-US" UICulture="en-US"
</code></pre>
<p>Again, this is only on the initial load after compiling the code, when that page first loads. Other web forms pages are unaffected, even if they descend from System.Web.Mvc.ViewPage. All subsequent loads treat the culture correctly. Just changing the .aspx file doesn't cause this, the c# code has to be compiled to cause this.</p>
<p>More data:
I have it tracked down to the Render method. Before the Render method, the culture is en-US and afterwards it is en-GB (again only on initial pageload after compilation).</p>

Python plot base64 string as image

Segmentation fault in OpenGL under Linux
|
<p>I am following some tutorials and came up with the following code:</p>
<pre><code>// rendering.cpp
#include "rendering.h"
#include <GL/gl.h>
#include <GL/freeglut.h>
void DrawGLScene()
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
glLoadIdentity();
}
int InitGL(int argc, char** argv)
{
/*glShadeModel(GL_SMOOTH);
glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
glClearDepth(1.0f);
glEnable(GL_DEPTH_TEST);
glDepthFunc(GL_LEQUAL);
glHint(GL_PERSPECTIVE_CORRECTION_HINT, GL_NICEST);*/
glutInit(&argc, argv);
glutInitWindowSize(500, 500);
glutInitWindowPosition(100, 100);
glutDisplayFunc(DrawGLScene);
glutCreateWindow("Swimming Simulation");
glutMainLoop(); // Enter GLUT's main loop
return true;
}
</code></pre>
<p>My main function is very simple and only calls that function:</p>
<pre><code>#include "rendering.h"
int main(int argc, char** argv)
{
InitGL(argc, argv);
return 0;
}
</code></pre>
<p>I am compiling with this command:</p>
<pre><code>g++ -Wall -g swim.cpp rendering.cpp -lglut -lGLU -o swim
</code></pre>
<p>Running <code>swim</code> creates a window as expected. However, if I uncomment the lines in <code>InitGL</code>, then I get a segmentation fault when running the program:</p>
<pre><code>(gdb) r

Adding Table.Row fadeout transition
|
<p>I've built a simple add-your-todos system in React using Semantic-UI-React. It currently looks like this:</p>
<p><a href="https://i.stack.imgur.com/h1u43.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/h1u43.gif" alt="before-transition-attempt"></a></p>
<h2>Problem description, and my attempt</h2>
<p>When the user clicks on the red bin icon, <strong>I'd like to delete the Table.Row using a Fadeout Transition</strong>. It currently deletes the row, but an animation here would make the user experience more enjoyable. <a href="https://react.semantic-ui.com/modules/transition#transition-example-transition-explorer" rel="nofollow noreferrer">I've visited the docs and tried to implement the solution</a>, using a Transition.Group component.</p>
<h2>...but it didn't work well</h2>
<p>After trying to solve this problem on my own, I got some unexpected behaviours. First of all, rows don't fadeout. Furthermore, all Table.Cell kind of "blend" into one single cell, which is annoying. See the (gruesome) result:</p>
<p><a href="https://i.stack.imgur.com/B8LZ7.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/B8LZ7.gif" alt="after-transition-attempt"></a></p>
<h2>The Todo component (before)</h2>
<p>Each Todo row is being dynamically added on the Table using a Todo component, which, before implementing Transition.Group, looked like this:</p>
<pre><code>const React = require('react');
const moment = require('moment');
import { Table, Checkbox, Icon, Popup, Grid, Button } from 'semantic-ui-react';
class Todo extends React.Component {
constructor(props) {
super(props);
}
render() {
const { id, text, completed, createdAt, completedAt } = this.props;
const renderDate = (date) => {
const timestamp = date;
if (timestamp)
return `${moment.unix(timestamp).format('MMM Do YYYY @ h:mm a')}`;
return '';
}
const renderPopup = () => {
if (completedAt) {
return (
<Popup trigger={<Icon name="calendar check" size="large"/>} header={'Completed at'} content={renderDate(completedAt)}/>
);
} else {
return (
''
);
}
}
return (
<Table.Row>
<Table.Cell>
<Grid columns="equal">
<Grid.Column width={3}>
<Checkbox toggle
defaultChecked={completed}
onClick={() => this.props.onToggle(id)} />
</Grid.Column>
<Grid.Column textAlign="left">
{renderPopup()}
</Grid.Column>
</Grid>
</Table.Cell>
<Table.Cell>{text}</Table.Cell>
<Table.Cell>{renderDate(createdAt)}</Table.Cell>
<Table.Cell textAlign="right">
<Button basic color="red" icon="trash"
onClick={() => {
this.props.onRemoveTodo(id);
this.handleFadeoutItem();
}}/>
</Table.Cell>
</Table.Row>
);
}
}
module.exports = Todo;
</code></pre>
<h2>The component (after)</h2>
<p>This is how it looks now (which is obviously wrong!):</p>
<pre><code>const React = require('react');
const moment = require('moment');
import { Table, Checkbox, Icon, Popup, Grid, Button, Transition } from 'semantic-ui-react';
class Todo extends React.Component {
constructor(props) {
super(props);
this.state = {
visible: true
};
this.handleFadeoutItem = this.handleFadeoutItem.bind(this);
}
handleFadeoutItem () {
this.setState({
visible: false
});
}
render() {
const { visible } = this.state;
const { id, text, completed, createdAt, completedAt } = this.props;
const renderDate = (date) => {
const timestamp = date;
if (timestamp)
return `${moment.unix(timestamp).format('MMM Do YYYY @ h:mm a')}`;
return '';
}
const renderPopup = () => {
if (completedAt) {
return (
<Popup trigger={<Icon name="calendar check" size="large"/>} header={'Completed at'} content={renderDate(completedAt)}/>
);
} else {
return (
''
);
}
}
return (
<Transition.Group as={Table.Row} visible={visible} animation="fade" duration={500}>
<Table.Row>
<Table.Cell>
<Grid columns="equal">
<Grid.Column width={3}>
<Checkbox toggle
defaultChecked={completed}

</Grid.Column>
</Grid>
</Table.Cell>
<Table.Cell>{text}</Table.Cell>
<Table.Cell>{renderDate(createdAt)}</Table.Cell>
<Table.Cell textAlign="right">
<Button basic color="red" icon="trash"
onClick={() => {
this.props.onRemoveTodo(id);
this.handleFadeoutItem();
}}/>
</Table.Cell>
</Table.Row>
</Transition.Group>
);
}
}
module.exports = Todo;
</code></pre>
<p>Any help offered will be greatly appreciated!</p>
<hr>
<p><strong>EDIT</strong></p>
<p>@Adrien's answer partially solved my problem. Now every cell is in its place, but the animation transition doesn't seem to play. Furthermore, the calendar icon next to my "completed" checkboxes (check the initial, unmodified version of the app) seem to disappear. Any idea why these two things happen? See:</p>

Create Shiny Presentation from Shiny App?

<p>I found this - <a href="http://shiny.rstudio.com/gallery/download-knitr-reports.html" rel="nofollow">http://shiny.rstudio.com/gallery/download-knitr-reports.html</a> - awesome example that can create static PDFs, HTMLs, and Word Docs.</p>
<p>What I want to be able to do is upload a data set that can then generate a templatized Shiny Presentation. I've tried multiple routes with little success. The furthest I've gotten is including this code in my markdown file:</p>

LDAP authentication using passport-ldapauth on Node.js
|
<p>I've been struggling with passport-ldapauth for a couple of days, and I have no more ideas left what am I doing wrong.</p>
<p>Briefly, I have a project that uses two passport strategies: local and LDAP. Local strategy works perfectly for me, but LDAP is the problematic one.</p>
<p>I have a read-only user for AD (let's call it "ldap-read-only-admin"), and I am able to connect with this user via external LDAP client and view the relevant OU. I have also triple-checked the SearchBase, and it seems to be correct.</p>
<p>However, when passing the same configuration to passport-ldapauth, it seems that it cannot bind user credentials (I guess). Any ideas on how to debug this will be much appreciated.</p>
<p>This is the app.js:</p>
<pre><code> var express = require("express");
var app = express();
var path = require("path");
var session = require("express-session");
var mongoose = require("mongoose");
var passport = require("passport");
var flash = require("connect-flash");
var cookieParser = require("cookie-parser");
var bodyParser = require("body-parser");
var morgan = require("morgan");
var configDB = require('./config/database.js');
require('./config/passport.js')(passport); // pass passport for configuration
app.use(express.static(__dirname + '/public'));
app.set('view engine', 'ejs');
//connect to the Database
var promise = mongoose.connect(configDB.url, {
useMongoClient: true,
});
app.use(morgan('dev')); // log every request to the console
app.use(cookieParser()); // read cookies (needed for auth)
//app.use(bodyParser()); // get information from html forms
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(bodyParser.json({
extended: true
}));
// configuring passport
app.use(session({ secret: 'secret', resave: true, saveUninitialized: true })); // session secret
app.use(passport.initialize());
app.use(passport.session()); // persistent login sessions
app.use(flash()); // use connect-flash for flash messages stored in session
require('./modules/routes.js')(app, passport); // load our routes and pass in our app and fully configured passport
//make Web server listen on a specific port
app.listen(3000);
logger.info("Listening on port 3000");
</code></pre>
<p>This is routes.js (the relevant part):</p>
<pre><code>module.exports = function(app, passport) {
app.post('/', function(req, res, next) {
passport.authenticate('ldap-login', {session: true}, function(err, user, info) {
console.log("user: " + user);
console.log("info: " + JSON.stringify(info));
if (err) {
return next(err); // will generate a 500 error
}
// Generate a JSON response reflecting authentication status
if (! user) {
return res.send({ success : false, message : 'authentication failed' });
}
return res.send({ success : true, message : 'authentication succeeded' });
})(req, res, next);
});
}
</code></pre>
<p>And this is passport.js:</p>
<pre><code> var LocalStrategy = require('passport-local').Strategy;
var LdapStrategy = require('passport-ldapauth').Strategy;
// load the user model
var User = require('../modules/user.js');
// expose this function to our app using module.exports

});
// used to deserialize the user
passport.deserializeUser(function(id, done) {
User.findById(id, function(err, user) {
done(err, user);
});
});
// =========================================================================
// LOCAL LOGIN =============================================================
// =========================================================================
passport.use('local-login', new LocalStrategy({
passReqToCallback : true // allows us to pass back the entire request to the callback
},

// find a user whose email is the same as the forms email
// we are checking to see if the user trying to login already exists
User.findOne({ username : username }, function(err, user) {
// if there are any errors, return the error before anything else
if (err)
return done(err);
// if no user is found, return the message
if (!user)
return done(null, false, req.flash('loginMessage', 'The username "' + username + '" is not found.')); // req.flash is the way to set flashdata using connect-flash
// if the user is found but the password is wrong
if (!user.validPassword(password))
return done(null, false, req.flash('loginMessage', 'Oops! Wrong password.')); // create the loginMessage and save it to session as flashdata
// all is well, return successful user
return done(null, user);
});
}));
// =========================================================================
// LDAP Login ==============================================================
// =========================================================================
var opts = {
server: {

Make the PHP MySql Search Engine and Pagination work
|
<p>I don't know how to make the search through another table. how should i do that?
the table name is comments and i want to search for all the post stored in the column name kom</p>
<p>Another thing is that i cant get the pagination start working...
I started the pagination within an else statment because i only need it when i get more than 1 result.
I can get the page links showing and limit the search posting showing but when i click on one off the links i cant get to the next page
Heres the code</p>
<pre><code><?php
$search = $_POST["search"];
$field = $_POST["field"];
if($_POST["submit"] && $search)

Spring LDAP Context.REFERRAL to follow
|
<p>How do I set the LDAP Context.REFERRAL to follow in a Spring Security configuration? This is related to a problem I already reported and for which I found an unsatisfactory solution before discovering the real solution I am seeking for involve setting this environment attribute in the LDAP context to follow the referral for the ActiveDirectoryLdapAuthenticationProvider.</p>
<p>Here is the reference to my original question: <a href="https://stackoverflow.com/questions/29658844/spring-security-4-0-0-activedirectoryldapauthenticationprovider-badcredentia">Spring Security 4.0.0 + ActiveDirectoryLdapAuthenticationProvider + BadCredentialsException PartialResultException</a></p>
<p><strong>Addendum:</strong> It seems no one is having such an environment here. Despite the silence on this problem, I post here my configuration hoping someone will be able to help me with this. I just don't know what I should do to solve this problem.</p>
<p>Here are the error messages in my log:</p>

</code></pre>
<p>The two beans with ids contextSource and ldapTemplate seems not to change anything. I was trying to get the referral follow behavior. It seems not the right way to configure it. Also, here the port in the ldap URL is set to 3268 because it is the general catalog and someone in another description elsewhere suggested to use it. But, the results are exactly the same with port 389.</p>
<p>If I change the first constructor argument in the bean monFournisseurAD to set it to a single userPrincipalName domain, it will work for all users into that domain. While I can actually authenticate anyone from the command line using ldapsearch command using dept.company.com instead of the userPrincipalName domain associated directly to the user. In fact, if I enter a wrong password, I will get the specific wrong password message. This seems to prove the user is actually authenticated by AD/LDAP, however Spring fails later to fetch the attributes for that user.</p>
<p>How can I solve this problem?</p>

Unable to generate call to cell phone using asterisk
|
<p>I'm currently working on a project 'email to voice call'. Using python i'v extracted the email & converted it into speech and saved in a WAV file. Now using asterisk (I'v installed Asterisk 10.2.1 on my ubuntu 10.10 os) i want to generate call to the cell phone (say 919833000000 india's no.) of the user through my system. </p>
<p>I have written a python code to connect to asterisk manager interface. Also i have configured the sip.conf and extensions.conf files as well as manager.conf. I have registered with voip provider <strong>voiceall.com</strong> and have a username password of it. </p>
<p>Now when i'm executing the python code, the code is getting executed without any error but nothing is happening. No call is getting generated. Can anyone help me out with this.
The python code is as below:</p>
<pre><code>import sys, os, socket, random

HOST = '127.0.0.1'
PORT = 5038
# Asterisk Manager username and password
USER = 'MYUSERNAME'

# Set the name of the SIP trunk to use for outbound calls
TRUNK = 'voiceall'
OUTBOUND = '919833000000'
# Send the call details to the Asteirsk Manager Interface
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
sleep(3)

WorkManager stops scheduling periodic Worker after the app closes
|
<p>maybe this is yet another question about WorkManager, but I really can't find a solution...</p>
<p>I'm trying, as the title suggests, to run a periodic work every 15 minutes. Actually in the worker I'm polling some data every minute. After every poll, every almost 1 second I check if the worker is being stopped and if so return, otherwise keep waiting until 1 minute is reached and poll data again.</p>
<p>According to the documentation this should work and indeed it is, until I kill the app from the recent app screen.</p>
<p>Here is the code:</p>
<pre><code>package com.qsea.app.cordova;
import android.content.Context;
import android.os.SystemClock;
import android.util.Log;
import androidx.work.Worker;
import androidx.work.WorkerParameters;
public class ServerListenerWorker extends Worker {
public static final String TAG = "ServerListenerWorker";
public ServerListenerWorker(
Context appContext,
WorkerParameters workerParams
) {
super(appContext, workerParams);
}
@Override
public Result doWork() {
Log.d(TAG, "Doing work");
final long startTime = SystemClock.elapsedRealtime();
final int maxDelta = 840000; // 14 minutes
while (true) {
// I did this to stop this worker until 15 minutes
// and then let the next worker run
if (SystemClock.elapsedRealtime() - startTime >= maxDelta) {
break;
}
// Here I'm polling data, if the polling results in a failure
// I return Result.retry()
// It avoid waiting if it remains only 1 minute until the max time
if (SystemClock.elapsedRealtime() - startTime >= (maxDelta - 60000)) {
break;
}
for (int i = 0; i < 60; i++) {
SystemClock.sleep(950);
// Here it checks if it is stopped
if (isStopped()) {
Log.d(TAG, "Detected stop"); // this is actually never reached
break;
}
}
}
return Result.success();
}
}
</code></pre>
<p>And I do as following to start the work</p>
<pre><code>Constraints constraints = new Constraints.Builder().setRequiredNetworkType(NetworkType.CONNECTED).build();
PeriodicWorkRequest periodicWorkRequest = new PeriodicWorkRequest.Builder(ServerListenerWorker.class, 15, TimeUnit.MINUTES)
.addTag(serverListenerWorkerUID)
.setConstraints(constraints)
.build();
WorkManager.getInstance(cordova.getActivity()).enqueueUniquePeriodicWork(serverListenerWorkerUID, ExistingPeriodicWorkPolicy.KEEP, periodicWorkRequest);
</code></pre>
<p>I check the correct working of the worker by viewing the log of my server (If I receive the request it is working fine) and it seems to work ok until I close the app. Then it stops running the actual worker and never run a worker again until I reopen the app, where the work seems to be enqueued and resumes right after the app opening.</p>
<p>Am I doing something wrong in the initialization?
I have also <code><service android:name=".ServerListenerWorker" android:permission="android.permission.BIND_JOB_SERVICE" /></code> in my AndroidManifest.xml</p>
<p>Is this expected behavior?</p>
<p>I read that chinese ROM have additional restriction to background services and I have a HUAWEI, which seems to be the worst in this. So could it be the device? And if so, how do Facebook, WhatsApp, Instagram and others manage this to work even in these devices?</p>

Linq group by parent property order by child
|
<p>Basicly what i am trying to do is getting the parent grouped by Parent.type where their Child.type has status 'y' ordered by child.Date</p>
<p>As an example i created these classes:</p>
<pre><code>public class Collection
{
public IEnumerable<Parent> Parents { get; set; }
public int Id { get; set; }
}
public class Parent
{
public int Id { get; set; }
public Type type { get; set; }
public IEnumerable<Child> Children { get; set; }
}
public class Child
{
public int Id { get; set; }
public Status Status { get; set; }
public DateTime Date { get; set; }
}
public enum Type
{
a,
b
}
public enum Status
{
x,
y
}
</code></pre>
<p>What i want is a list of Parents of each type where the Child's Date is highest in value.</p>
<p>To get this example going i added some test data:</p>
<pre><code>Collection collection= new Collection
{
Id = 1,
Parents = new List<Parent>
{
new Parent
{
Id= 1,
type = Type.a,
Children = new List<Child>
{
new Child
{
Id = 1,
Status = Status.y,
Date = DateTime.Now.AddDays(-1)
},
new Child
{
Id = 2,
Status = Status.x,
Date = DateTime.Now.AddDays(-1)
}
}
},
new Parent
{
Id= 2,
type = Type.b,
Children = new List<Child>
{
new Child
{
Id = 3,
Status = Status.y,
Date = DateTime.Now.AddDays(-2)
},
new Child
{
Id = 4,
Status = Status.x,
Date = DateTime.Now.AddDays(-2)
}
}
},
new Parent
{
Id= 3,
type = Type.a,
Children = new List<Child>
{
new Child
{
Id = 5,
Status = Status.y,
Date = DateTime.Now.AddDays(-3)
}
}
},
new Parent
{
Id= 4,
type = Type.b,
Children = new List<Child>
{
new Child
{
Id = 6,
Status = Status.y,
Date = DateTime.Now.AddDays(-3)
},
new Child
{
Id = 7,
Status = Status.y,
Date = DateTime.Now.AddDays(-4)
},
new Child
{
Id = 8,
Status = Status.x,
Date = DateTime.Now.AddDays(-4)
}
}
},
}
};
</code></pre>
<p>The result of the select should be a List containing 2 Parents. One for each type ( a and b ). Both of these still containing all of their Child objects.</p>
<p>Is there any simple solution for this ?</p>
<p>I tried something like:</p>
<pre><code>List<Parent> test = collection.Parents
.GroupBy(m => m.type)
.Select(
m => m.OrderByDescending(
mm => mm.Children.Select(
r => r).OrderByDescending(
r => r.Date)).FirstOrDefault()).ToList();
</code></pre>
<p>But that didn't end well.</p>
<p>=====UPDATE=====</p>
<p>Thanks to the example of Enigmativity this issue is solved. I made a slight modification to the linq query as the original content i am using is provided by Entity Framework (6). This meant for me that the selected Parent object was not containing any Children, so i had to select into a new object type (As we can't instantiate a new object of the type provided by the Entity Framework model) . Also my Parents were in another IEnumerable so I had to use a SelectMany on the Parents as well.</p>
<p>This resulted in something like this: (This won't work with the test classes though)</p>
<pre><code>var result =
collection
.SelectMany(c => c.Parents)
.GroupBy(p => p.type)
.SelectMany(gps =>
gps
.SelectMany(
gp => gp.Children.Where(c => c.Status == Status.y),
(gp, c) => new { gp, c })
.OrderByDescending(gpc => gpc.c.Date)
.Take(1)
.Select(gpc => new ParentData {Id = gpc.gp.Id, Children= gpc.gp.Children}))
.ToList();
</code></pre>

Check if value in Firebase Realtime Database is equal to String

how receive arraylist in fragment

Getting session and SFTP channel in Java using JSch library
|
<p>I am using JSch library for SFTP. I need to do several operations on SFTP server like move remote files in other directory, pull files, etc. For all these operations I need <code>Session</code> and from it I get <code>Channel</code> an then cast it to <code>ChannelSftp</code>. This is redundant step. So I thought of abstracting it into a <code>private</code> method.</p>
<pre><code>private ChannelSftp getChannelSftp() throws JSchException
{
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
JSch jsch = new JSch();
Session session;
session = jsch.getSession(VENDOR1_USERID, VENDOR1_SERVER, VENDOR1_PORT);
session.setPassword(VENDOR1_PASSWORD);
session.setConfig(config);
session.connect();
ChannelSftp channelSftp = null;
Channel channel = session.openChannel("sftp");
channel.connect();
channelSftp = (ChannelSftp) channel;
return channelSftp;
}
</code></pre>
<p>But after the SFTP operation I need to disconnect from channel and session <strong>both</strong>.
With above method, though I can disconnect from <code>Channel</code> in the calling method but I can't disconnect from <code>Session</code> as I don't have its instance which might be a leak so I now separated that into <code>getSession()</code> method and now <code>ChannelSftp</code> creation is duplicated in all methods. </p>
<p>What is better way to <strong><em>design/refactor</em></strong> it?</p>
<pre><code>private Session getSession() throws JSchException
{
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
JSch jsch = new JSch();
Session session;
session = jsch.getSession(VENDOR1_USERID, VENDOR1_SERVER, VENDOR1_PORT);
session.setPassword(VENDOR1_PASSWORD);
session.setConfig(config);
session.connect();
return session;
}
</code></pre>
<p><strong>Calling Method example:</strong> - <em>Duplicated code indicated</em></p>
<pre><code>public void sftp(File file) throws SftpException, FileNotFoundException, JSchException
{
Session session = getSession();
/* Duplicate code START*/
if ( session == null ) throw new SftpException(0 , "Service: Session is NULL");
ChannelSftp channelSftp = null;
Channel channel = session.openChannel("sftp");
channel.connect();
channelSftp = (ChannelSftp) channel;
/* Duplicate code END*/
channelSftp.cd(VENDOR1_PATH);
channelSftp.put(new FileInputStream(file), file.getName());
channelSftp.disconnect();
session.disconnect();
}

Oracle procedure to kill jobs that do not complete in given time
|
<p>I have created an oracle procedure to reschedule job that do not complete in a given amount of time:</p>
<pre><code>create or replace procedure kill_stuck_jobs
as
begin
for x in (
select j.sid,
s.spid,
s.serial#,
j.log_user,
j.job,
j.broken,
j.failures,
j.last_date,
j.this_date,
j.next_date,
j.next_date - j.last_date interval,
j.what
from
(select
djr.SID,
dj.LOG_USER,
dj.JOB,
dj.BROKEN,
dj.FAILURES,
dj.LAST_DATE,
dj.LAST_SEC,
dj.THIS_DATE, dj.THIS_SEC,
dj.NEXT_DATE, dj.NEXT_SEC, dj.INTERVAL, dj.WHAT
from dba_jobs dj, dba_jobs_running djr
where dj.job = djr.job ) j,
(select p.spid, s.sid, s.serial#
from v$process p, v$session s
where p.addr = s.paddr ) s
where j.sid = s.sid and
j.next_date+15/1440 < sysdate

execute immediate 'alter system disconnect session '''|| x.sid|| ',' || x.serial# || ''' immediate';
EXEC DBMS_JOB.BROKEN(x.job,FALSE);
dbms_output.put_line( 'Alter session done' );
end loop;
end;
</code></pre>
<p>But this procedure compiles with error:</p>
<pre><code>PLS-00103: Encountered the symbol "DBMS_JOB" when expecting one of the following:
:= . ( @ % ;
The symbol ":=" was substituted for "DBMS_JOB" to continue.
</code></pre>
<p><img src="https://i.stack.imgur.com/vLxRm.png" alt="enter image description here"></p>
<ul>
<li><p>Here came the discussion on dbms_job and dbms_scheduler_job. Actually the problem here is I created materialized view using linked db but sometime the query is stuck for whole day in session with <code>SQL*Net more data from dblink</code> . I used the above procedure to kill jobs that are created while creating materialized view and I am killing the session using :</p>
<pre><code>create or replace procedure kill_stuck_refresh as
begin
for x in (
select username, osuser, sid, serial#, seconds_in_wait,
event, state, wait_class
from v$session
where username is not null
and seconds_in_wait > 600
and event = 'SQL*Net more data from dblink'
) loop
execute immediate 'alter system disconnect session '''|| x.sid
|| ',' || x.serial# || ''' immediate';
dbms_output.put_line( 'Alter session done' );
end loop;
end; -- end of kill_stuck_refresh;
</code></pre></li>

Unable to Open Connection to Zebra Printer
|
<p>I am currently in the process of creating an android application that requires the ability to print tickets/receipts from a mobile printer. The organization I am currently with has decided to purchase android tablets that are currently running 7.0 as well as Zebra Mobile Printers (ZQ510). We determined that using the BluetoothConnectionInsecure would be the best method of connecting and printing with these printers, since the application will be used on a multitude of tablets each connecting to their own printers.</p>
<p>Although we were able to successfully connect and print on the previous version of the application which was designed to work with android devices running 5.0 and above, it seems that the current version of our application is unable to establish a connection with the printer. </p>
<p>I've looked through stack for a similar error, but was unable to find any. If there is one similar to mine that exists, I would appreciate a link.</p>
<p><a href="https://stackoverflow.com/questions/36262106/zebra-printer-connection-failed-read-failed-socket-might-closed-or-timeout-re">Zebra printer connection failed “read failed, socket might closed or timeout, read ret: -1”</a></p>

</code></p>
<p>The method I am currently using to establish connection with the printer is as follows:</p>
<p>Creating an intent to search for discoverable devices, then passing that intent to my Bluetooth class:</p>
<pre><code>Intent discoverableIntent =
new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
BluetoothUnsecurePrint bluetoothUnsecurePrint = new BluetoothUnsecurePrint(resultMap,violationResults,getActivity(), theTicketNumber, discoverableIntent);
bluetoothUnsecurePrint.print();
</code></pre>
<p>Gather the list of devices found and grab MAC address of devices already paired to the tablet:</p>
<pre><code> public void print(){
//ask user to allow device to be discoverable by paired printer, display dialog box
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
userActivity.startActivity(discoverableIntent);
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter().getAddress();
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
// Device does not support Bluetooth
}
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if (pairedDevices.size() > 0) {
// There are paired devices. Get the name and address of each paired device.
for (BluetoothDevice device : pairedDevices) {
String deviceHardwareAddress = device.getAddress(); // MAC address
sendZplOverBluetooth(deviceHardwareAddress);
Log.d(TAG,device.getAddress()+ device.getName()+device.getBondState());
Intent ticketFinishedIntent = new Intent(userActivity, OffendingVehicleSearch.class);
userActivity.startActivity(ticketFinishedIntent);
}
}
}
</code></pre>
<p>Using the bluetooth mac address to establish a connection to the printer and then print the written data.</p>
<pre><code>private void sendZplOverBluetooth(final String theBtMacAddress) {
new Thread(new Runnable() {
public void run() {
try {
// Instantiate insecure connection for given Bluetooth&reg; MAC Address.
Connection thePrinterConn = new BluetoothConnectionInsecure(theBtMacAddress);
// Initialize
Looper.prepare();
Log.d(TAG,thePrinterConn.getSimpleConnectionName());
// Open the connection - physical connection is established here.
thePrinterConn.open();
Log.d(TAG, String.valueOf(thePrinterConn.bytesAvailable()));
// Send the data to printer as a byte array.
thePrinterConn.write(generateZPL().getBytes());
// Make sure the data got to the printer before closing the connection
Thread.sleep(500);
// Close the insecure connection to release resources.
thePrinterConn.close();
Looper.myLooper().quit();
} catch (Exception e) {
// Handle communications error here.
e.printStackTrace();
}
}
}).start();
}
</code></pre>
<p>I did come across some other semi-related forum posts concerning possible new permissions needed for the manifest file, however it looks like those permissions do not make a difference in the connection error.</p>
<p>

Spring Hibernate Lazy loading - no session
|
<p>i have a lazy loading problem at a service call or at least i thought i just have a lazy loading problem... it seems to be, that i have a session problem => the session is not available during the hole service call.</p>
<p>This is my service-source:</p>
<pre><code>@Service
public class MyServiceImpl implements MyService{
@Autowired
private MyRepository myRepository;
@Override
@Transactional
public MyDTO find(String pk){
MyObject o = myRepository.findByPK(pk);
o.lazyCall();//Exception, but only at server call, tests runs without any problems
}
}
</code></pre>
<p>My Test-Class is annotated with:</p>
<pre><code>@Test
@ContextConfiguration (locations = { "classpath:spring-test-config.xml" })
@TransactionConfiguration (transactionManager="transactionManager", defaultRollback=true)
@Transactional
public class MyServiceTest
extends AbstractTransactionalTestNGSpringContextTests{
</code></pre>
<p>
and the test runs fine.</p>
<p>But if i deploy my stuff into a jetty server, i receive this exception:</p>
<p><div class="snippet" data-lang="js" data-hide="false">
<div class="snippet-code">

<p>And finally my server datasource / tx configuration looks like this:</p>

</code></pre>
<p>So what's the difference? Why is the behavior between the test and the server different? Why i don't have a database session in my servicemethod, but when i load something from the database i have a session? I read something about OpenSessionInViewFilter but this seems to be a solution for a front end app => but i want to implement a rest-server, which is called by a frontend.</p>
<p>Any ideas? Please help. </p>

How to fix '_react["default"].memo is not a function. (In '_react["default"].memo(connectFunction)' error in React native?
|
<p>I am trying to connect Redux mapStateToProps() and mapActionCreators() to Login Screen through Container and I am using React navigation.</p>
<p>After build my app the following error message appears:</p>
<blockquote>
<p>_react["default"].memo is not a function. (In '_react["defaults"].memo(connectFunction)', '_react["defaults"].memo' is undefined.</p>
</blockquote>
<p>I searched for a while but what I have gotten is that React.memo() helps us control when our components rerender but I don't use any code related to React.memo().</p>
<p>Login Screen: (screens/LoginScreen/index.js)</p>
<pre><code>import React from 'react';
import {Dimensions, View} from 'react-native';
//Get width of mobile screen
var width = Dimensions.get("window").width;
var height = Dimensions.get("window").height;
export default class LoginScreen extends React.Component {
constructor(props){
super(props);
this.state = {
}
}
render() {
return (
<View style={styles.container}>
<Text>Log In page</Text>
</View>
);
}
}
LoginScreen.defaultProps = {
}
const styles = {
container: {
flex: 1
}
}

auto closing bootstrap alerts after form submission
|
<p>I have an ajax form that submits data into a database, and it uses bootstrap alerts for when it has been successful, I would like the alerts to close after a period of time has passed, but this needs to happen everytime.</p>
<p>For example if I load the form and make some changes and press submit it will show the success alert and then close, if I then submit the form again for example I forgot to change something perhaps, it will show the alert again, but this time it doesn't close.</p>
<p>How can I get the alert to show and close everytime?</p>
<p>I've provided an example with a hardcoded alert in the page, this is however written into the page using javascript, I couldn't figure out a way to provide a full example with working ajax code that showed the success alert with no back end PHP.</p>

Destructor causing segmentation fault
|
<p>I have implemented a class string, similar to std::string one.
I have a problem when the destructor is called: the field length has the length of the characters allocated in field.
This is the class:</p>
<pre><code>class indexException:public std::exception
{
public:
virtual const char* what()
{
return "Index is either too long, or negative";
}
};
class string
{
public:
static const unsigned int length_max=100;
string(const char* field=NULL)
{
if(field!=NULL)
{
const unsigned int length=strlen(field);
this->field=new char[length+1];
this->length=length;
for(unsigned int i=0;i<=length;i++)
this->field[i]=field[i];
}
else
{
this->field=NULL;
length=0;
}
}
string(string& str)
{
string(str.field);
}
~string()
{
if(length>0)
delete field;
}
char& operator[] (int i) const throw()
{
try
{
if(i<0 || i>=(int)length)
throw indexException();
}
catch(indexException& e)
{
std::cerr << e.what() << std::endl;
}
return field[i];
}
string& operator=(const char* field)
{
const unsigned int length=strlen(field);
if(this->length>0)
delete this->field;
this->field=new char[length];
this->length=length;
for(unsigned int i=0;i<length;i++)
this->field[i]=field[i];
return *this;
}
string& operator= (const string& str)
{
if(this!=&str)
*this=str.field;
return *this;
}
operator char* ()
{
return field;
}
friend std::ostream& operator<< (std::ostream& out, string& str);
friend std::istream& operator>> (std::istream& in, string& str);
public:
unsigned int length;
char* field;
};
std::ostream& operator<<(std::ostream& out, string& str)
{
out << str.field;
return out;
}
std::istream& operator>> (std::istream& in, string& str)
{
char temp[string::length_max];
in >> temp;
str=temp;
return in;
}
</code></pre>
<p>If I use the assignment operator, this doesn't cause a segmentation fault.
But it undirectly cause it.
I explain how:</p>
<pre><code>int main(int argc,char** argv)
{
string str="hi";
string str2=str;
return 0;
}
</code></pre>
<p>Putting a breakpoint into the assignment operator overloading, I realized that the assigment operator doesn't cause segmentation fault.
The problem is after, when exiting from main.
If I remove the destructor I don't get this segmentation fault, but I would know why I get this problem.</p>
<p>Edit: I have understood where's the problem.
I followed your suggestions but it still goes to segmentation fault.
But now it doesn't crash anymore on the destructor method, but on the assignment operator overloading:</p>
<pre><code> string& operator=(const char* field)
{
unsigned int length=0;
if(field!=NULL)
length=strlen(field);
else
field="";
if(this->length>0)
delete[] this->field;
this->field=new char[length+1];
this->length=length;
strcpy(this->field,field);
return *this;
}
</code></pre>
<p>The problem is when I delete this->field, the debugger stops there.
An example of segmentation fault:</p>
<pre><code>string str("hi");
string str2=str;
</code></pre>
<p>This causes segmentation fault.I suppone it's because str2 is not initialized, and length has an undefined value.
If I instead do this:</p>
<pre><code>string str("hi");
string str2;
str2=str;
</code></pre>
<p>There isn't any segmentation fault.Why?
I thought that calling :</p>
<pre><code>string str2;
</code></pre>
<p>Was also calling the constructor, or is that the "=" operator has the precedence?
How to solve this?</p>
<p>PS: I also changed other things,like the copy constructor.
Full code is here:
<a href="http://pastebin.com/ubRgaVr8" rel="nofollow">http://pastebin.com/ubRgaVr8</a></p>
<p>Solved: I changed the copy constructor as suggested in the accepted reply:</p>
<pre><code> string(const string& str)
{
length=str.length;
field=new char[str.length+1];
memcpy(field,str.field,length+1);
}
</code></pre>

Active Admin on Heroku doesn't work properly

<p>Hi I had active admin working fine before but I think it got messed up when I tried merging my github + heroku repositories. It seems to work fine locally but on Heroku I get the generic We're sorry, but something went wrong message. Here is the output of my heroku logs</p>

Error when using a DropDownListFor in a foreach loop in an MVC Razor view
|
<p>I am trying to create a simple form in ASP.MVC which shows a list of quotes, and allows the user to create work orders by selecting a person from a drop down list to assign that quote to, and then submitting the form all in one go.</p>
<p>My problem is that my use of DropDownListFor within a foreach loop is causing an error and I don't think I'm going about this the right way.</p>
<p>A (somewhat simplified) quote looks like this:</p>
<pre><code>public class QuoteItem
{
public QuoteItem()
{
this.IsWorkOrder = false;
}
[Key]
public int QuoteItemCostID { get; set; }
public string Item { get; set; }
public decimal? Subtotal { get; set; }
public bool IsWorkOrder { get; set; }
[NotMapped]
public string AssignedTo { get; set; }
}
</code></pre>
<p>I have a View Model configured as follows:</p>
<pre><code>public class UnassignedWorkOrdersViewModel
{
public IEnumerable<QuoteItemCost> QuoteItemCosts { get; set; }
public IEnumerable<SelectListItem> Trades { get; set; }
}
</code></pre>
<p>And a controller action that looks like this:</p>
<pre><code>public ActionResult Unassigned(int id = 0)
{
var trades = db.UserProfiles.Where(u => u.Typpe == "Trade").ToArray().Select(x => new SelectListItem
{
Value = x.FirstName + " " + x.LastName,
Text = x.FirstName + " " + x.LastName
}).ToList();
var quoteItems = db.QuoteItems
.Where(x => x.IsWorkOrder == false)
.ToList();
UnassignedWorkOrdersViewModel viewModel = new UnassignedWorkOrdersViewModel
{
Trades = trades,
QuoteItemCosts = quoteItemCosts
};
return View(viewModel);
}
</code></pre>
<p>My problem is that in my view, I'm trying to show each work order and the drop down list of trades next to it, and the way that I thought I'd do it is to map the class property "AssignedTo" to the value in the drop down list, however this doesn't work, as the DropDownList expects a LINQ expression as the first parameter:</p>
<pre><code>@model Project.ViewModels.UnassignedWorkOrdersViewModel
@if (Model.QuoteItemCosts.Any())
{
using (Html.BeginForm("Unassigned", "WorkOrder", FormMethod.Post, null))
{
@Html.AntiForgeryToken()
<table>
@foreach (var item in Model.QuoteItemCosts)
{
<tr>
<td style="width:100px;">
<b>Item:</b> @item.Item
</td>
<td style="width:200px;">
<b>Total:</b> @item.Subtotal
</td>
<td>
<b>Assign:</b>
@Html.DropDownListFor(
item.AssignedTo, // THIS LINE CAUSES AN ERROR
Model.Trades,
"", new { @id = "ddlStatus", @style = "width:100%" })
</td>
</tr>
}
</table>
}
</code></pre>
<p>How can I resolve this and am I even going about this the right way? On form submit, I should expect to get back the ViewModel which would then return all my QuoteItems, but with an AssignedTo entry if the user has selected a person from the drop down list.</p>
<p>Edit:</p>
<p>Andrei's suggestion below has helped and led me to another solution where my DropDownListFor now looks like this:</p>
<pre><code> @Html.DropDownListFor(
m => m.QuoteItemCosts.First(q => q.QuoteItemCostID == item.QuoteItemCostID).AssignedTo,
Model.Trades,
"", new { @id = "ddlStatus", @style = "width:100%" })
</code></pre>
<p>but when I submit the form the viewmodel is null:</p>
<pre><code> [HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Unassigned(UnassignedWorkOrdersViewModel viewModel)
{
// My viewModel is null
return RedirectToAction("Index");
}
</code></pre>
<p>I've updated my razor code to include a Html.BeginForm as well.</p>

Change color during writing a string into an image with drawstring
|
<p>I'm creating a string out of three smaller strings which I read in from three different text-files and then write the string into an image. I'd like to change the color for the paragraph in the middle of a created image. I can create the image with its three paragraphes, which looks like <a href="http://i50.tinypic.com/4id44y.jpg" rel="nofollow">this.</a></p>

Blocked while scraping goodreads.com
|
<p>I am trying to scrape a large sample (100k+) of the books available at "<a href="https://www.goodreads.com/book/show/" rel="nofollow noreferrer">https://www.goodreads.com/book/show/</a>", but I get continuously blocked.
So far I have tried to implement the following solutions in my code:</p>
<ul>
<li><p>Check the robots.txt to find what sites/elements are not accessible</p></li>
<li><p>Specify a header or multiple headers that randomly change</p></li>
<li><p>Use multiple working proxies to avoid being blocked</p></li>
<li><p>Set a delay up to 20 seconds between each scraping iteration that uses 10 simultaneous threads</p></li>
</ul>
<p>Here is a simplified version of the code that gets blocked while trying to scrape only the title and author of the book, without using multiple simultaneous threads:</p>

Howto call method from OSGI bundle?
|
<p>I have written this OSGI bundle:</p>
<pre><code>/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package CryptoLib;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
public class cryptoSha {
public cryptoSha() {
}
/** method for converting simple string into SHA-256 hash */
public String stringHash(String hash) throws NoSuchAlgorithmException{
MessageDigest md = MessageDigest.getInstance("SHA-256");
md.update(hash.getBytes());
byte byteData[] = md.digest();
/** convert the byte to hex format */
StringBuilder sb = new StringBuilder();
for (int i = 0; i < byteData.length; i++) {
sb.append(Integer.toString((byteData[i] & 0xff) + 0x100, 16).substring(1));
}
return sb.toString();
}
}
</code></pre>
<p>And this is the Acticator class:</p>
<pre><code> package com.CL_67;
import CryptoLib.cryptoSha;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
public class Activator implements BundleActivator {
private static BundleContext context;
public void start(BundleContext context) throws Exception {
Activator.context = context;
context.registerService(cryptoSha.class.getName(), new cryptoSha(), null);
System.out.println("Module CL-67 is Loaded ...");
}
public void stop(BundleContext context) throws Exception {
context.ungetService(context.getServiceReference(cryptoSha.class.getName()));
Activator.context = null;
System.out.println("Module CL-67 is Unloaded ...");
}
}
</code></pre>
<p>This is the EAR package which calls the bundle:</p>
<pre><code>import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import org.osgi.framework.BundleContext;
@Named("loginController")
@SessionScoped
public class userCheck extends HttpServlet implements Serializable {
public userCheck(){
}
@WebServlet(name = "CL_67", urlPatterns = {"/CL_67"})
public class cryptoSha extends HttpServlet {
@Inject
cryptoSha stringHash;
}
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
out.println(cryptoSha.stringHash("test"));
}
}
}
</code></pre>
<p>I successfully compile and deploy then on JBoss 7.1.0 but when I start the EAR package nothing happens. Can you help me to find where I'm wrong in the code?</p>
<p>kind regards,
Peter </p>
<p>EDIT:
Unfortunately I'm new to java programming and some of the code in the examples I don't understand how they work. Would you be so kind to help me with the example. I need to see how this code must be written in proper way in order to use it in future time? Would someone repair the code?</p>
<p>Thank you in advance.

Android - How to set color of a TextView and background together with SharedPreferences
|
<p>in my app I have a menu button called "Settings" in which I can choose what colours set up to the background of some layout. Unfortunately I combine two layouts together to show what I want to show, and the problem is that I can only set background colour (that is in a layout) but not the the colour of TextView (that is in the other layout). </p>
<p>Layout main.xml:</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>

I'd like to change the colours together (example: black colour for background and white colour for the text or white colour for the background and black colour for the text, etc.). How can I proceed?

How to find RC4 key from decrypted and encrypted data?
|
<p>I have some dump analysis in a documentation showing a bunch of encrypted data, and the resulting decrypted data. The algorithm used is explained (simple RC4). The only piece of information missing is the key used to get from the encrypted to the decrypted data.</p>
<p>I'm writing an automated test from this documentation material. I could chose some key of my own and recreate encrypted data from cleartext, but I wonder if there is any easy cryptanalysis way to find the original key that was used to encrypt the original bunch of data. </p>
<p>A brute force approach is probably possible as the key is quite small, but I'm much more interrested to know if any smarter approach exists.</p>
<p>Below is my current C encryption code (using OpenSSL):</p>

Equality operator overloads: Is (x!=y) == (!(x==y))?
|
<p>Does the C++ standard guarantee that <code>(x!=y)</code> always has the same truth value as <code>!(x==y)</code>?</p>
<hr />
<p>I know there are <em>many</em> subtleties involved here: The operators <code>==</code> and <code>!=</code> may be overloaded. They may be overloaded to have different return types (which only have to be implicitly convertible to <code>bool</code>). Even the <code>!</code>-operator might be overloaded on the return type. That's why I handwavingly referred to the "truth value" above, but trying to elaborate it further, exploiting the implicit conversion to <code>bool</code>, and trying to eliminate possible ambiguities:</p>
<pre><code>bool ne = (x!=y);
bool e = (x==y);
bool result = (ne == (!e));
</code></pre>
<p><strong>Is <code>result</code> guaranteed to be <code>true</code> here?</strong></p>
<p>The C++ standard specifies the equality operators in section 5.10, but mainly seems to define them <em>syntactically</em> (and some semantics regarding pointer comparisons). The <em>concept</em> of being <a href="http://en.cppreference.com/w/cpp/concept/EqualityComparable" rel="nofollow noreferrer">EqualityComparable</a> exists, but there is no dedicated statement about the relationship of its operator <code>==</code> to the <code>!=</code> operator.</p>
<p>There exist <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3950.html" rel="nofollow noreferrer">related documents from C++ working groups</a>, saying that...</p>
<blockquote>
<p>It is vital that equal/unequal [...] behave as boolean negations of each other. After all, the world would make no sense if both operator==() and operator!=() returned false! As such, it is common to implement these operators in terms of each other</p>
</blockquote>
<p>However, this only reflects the Common Sense™, and does not <em>specify</em> that they have to be implemented like this.</p>
<hr />
<p><sub>Some background: I'm just trying to write a function that checks whether two values (of unknown type) are equal, and print an error message if this is not the case. I'd like to say that the required concept here is that the types are <code>EqualityComparable</code>. But for this, one would still have to write <code>if (!(x==y)) {…}</code> and could <strong>not</strong> write <code>if (x!=y) {…}</code>, because this would use a different operator, which is not covered with the concept of <code>EqualityComparable</code> at all, and which might even be overloaded differently...</sub></p>
<hr />
<p>I know that the programmer basically <em>can</em> do whatever he wants in his custom overloads. I just wondered whether he is really <em>allowed</em> to do everything, or whether there are rules imposed by the standard. Maybe one of these subtle statements that suggest that deviating from the usual implementation causes undefined behavior, like the one that <a href="https://stackoverflow.com/questions/35943551/equality-operator-overloads-is-x-y-x-y/35943728?noredirect=1#comment59544090_35943728">NathanOliver mentioned in a comment, but which seemed to only refer to certain types</a>. For example, the standard <strong>explicitly</strong> states that for <em>container types</em>, <code>a!=b</code> is equivalent to <code>!(a==b)</code> (section 23.2.1, table 95, "Container requirements").</p>
<p>But for general, user-defined types, it currently seems that there are no such requirements. The question is tagged <code>language-lawyer</code>, because I hoped for a definite statement/reference, but I know that this may nearly be impossible: While one could point out the section where it said that the operators <em>have</em> to be negations of each other, one can hardly prove that none of the ~1500 pages of the standard says something like this...</p>
<p>In doubt, and unless there are further hints, I'll upvote/accept the corresponding answers later, and for now assume that for comparing not-equality for <code>EqualityComparable</code> types should be done with <code>if (!(x==y))</code> to be on the safe side.</p>

post to SQL Server api with Express.js
|
<p>I´ve been testing Apis with Express.js from SQL Server database. With get i have no problems, but i cannot post.</p>
<p>This is y code so far:</p>
<pre><code> const express = require('express');
const bodyParser = require('body-parser');
const sql = require('mssql');
const app = express();
app.use(bodyParser.json());
app.use(function (req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Methods", "GET,HEAD,OPTIONS,POST,PUT");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, contentType,Content-Type, Accept, Authorization");
next();
});
const server = app.listen(process.env.PORT || 8080, function () {
var port = server.address().port;
console.log("App now running on port", port);
});
const dbConfig = {
user: "daUser",
password: "daPass",
server: "daServer",
database: "DaDB"
}
const executeQuery = function (res, query) {
sql.connect(dbConfig, function (err) {
if (err) {
console.log(err);
res.send(err);
}
else {
// create Request object
var request = new sql.Request();
// query to the database
request.query(query, function (err, result) {
if (err) {
console.log(err);
res.send(err);
}
else {
res.send(result);
}
});
}
});
}
app.get("/api/HolidayBaseApi", function (req, res) {
var query = "SELECT * FROM [HolidaysBase]";
executeQuery(res, query);
})
app.post("/api/HolidayBaseApi", function (req, res) {
var query = "INSERT INTO [HolidaysBase] (EmployeeNumber, PeriodBegin, PeriodEnd, WorkedYears, DaysPerYear, TakenDays, RemainingDays) VALUES (req.body.EmployeeNumber, req.body.PeriodBegin, req.body.PeriodEnd, req.body.WorkedYears, req.body.DaysPerYear, req.body.TakenDays, req.body.RemainingDays)";
executeQuery(res, query);
})
</code></pre>
<p>When i'm triying to make the post, i get an error which says:</p>
<pre><code>The multi-part identifier \"req.body.RemainingDays\" could not be bound.
</code></pre>
<p>The error list all my fields with the same error. The format of every field it's fine. I'm sending the data like this in postman:</p>
<pre><code>{
"EmployeeNumber": "9",
"PeriodBegin": "2018-10-15",
"PeriodEnd": "2019-10-15",
"WorkedYears": "6",
"DaysPerYear": "18",
"TakenDays": "0",
"RemainingDays": "18"
}
</code></pre>
<p>Someone knows why is not letting me post the info?</p>
<p>I'm using Javascript, Express.js, Node.</p>
<p><strong>--- EDITION ---</strong></p>
<p>I've found two solutions. The first solution next:</p>
<pre><code> app.post("/api/HolidayBaseApi", function (req, res) {
var query = "INSERT INTO [HolidaysBase] (EmployeeNumber, PeriodBegin, PeriodEnd, WorkedYears, DaysPerYear, TakenDays, RemainingDays) VALUES ('"+req.body.EmployeeNumber+"','"+req.body.PeriodBegin+"','"+req.body.PeriodEnd+"','"+req.body.WorkedYears+"','"+req.body.DaysPerYear+"','"+req.body.TakenDays+"','"+req.body.RemainingDays+"')";
executeQuery(res, query);
});
</code></pre>
<p>With my code like this, i could make the post. But there was some comments that this way it's a little dangerous, 'cause it's easier to get an SQL attack injection. And found another solution: On the <code>const executeQuery</code> need to add <code>parameters</code> like this:</p>
<pre><code>const executeQuery = function (res, query, parameters) {
sql.connect(dbConfig, function (err) {
if (err) {
console.log(err);
res.send(err);
}
else {
// create Request object
var request = new sql.Request();
// query to the database
parameters.forEach(function (p) {
request.input(p.name, p.sqltype, p.value);
});
request.query(query, function (err, result) {
if (err) {
console.log("Error al correr query en la base: " + err);
res.send(err);
}
else {
res.send(result);
sql.close();
}
});
}
});
}
</code></pre>
<p>Then, on the <code>app.post</code>:</p>
<pre><code>app.post("/api/HolidayBaseApi", function (req, res) {
var parameters = [
{ name: 'EmployeeNumber', sqltype: sql.Int, value: req.body.EmployeeNumber },
{ name: 'PeriodBegin', sqltype: sql.VarChar, value: req.body.PeriodBegin },
{ name: 'PeriodEnd', sqltype: sql.VarChar, value: req.body.PeriodEnd },
{ name: 'WorkedYears', sqltype: sql.Int, value: req.body.WorkedYears },
{ name: 'DaysPerYear', sqltype: sql.Int, value: req.body.DaysPerYear },
{ name: 'TakenDays', sqltype: sql.Int, value: req.body.TakenDays },

iPhone Programming from book. incomplete implementation of class 'InstatwitViewController'
|
<p>Hey everyone, im doing an independent study of iphone programming in my high school. i got a book from a teacher "Head First Iphone Programming". I got through the first lesson (hello world with a button) without any problems, but now im onto the second lesson. It is a twitter application that uses a UIPickerview to display options. I have not been able to get anything to show up on the UIPickerview.</p>
<p>my InstatwitViewController.h looks like:</p>
<pre><code> #import <UIKit/UIKit.h>
@interface InstatwitViewController : UIViewController
<UIPickerViewDataSource, UIPickerViewDelegate> {
NSArray* activities;
NSArray* feelings;
}
@end
</code></pre>
<p>and my InstaTwitViewController.m looks like:</p>
<pre><code>#import "InstatwitViewController.h"
@implementation InstatwitViewController
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 2;
}
- (NSInteger)pickerView:(UIPickerView *)pickerViewNumberOfRowsInComponent : (NSInteger)component {
if (component == 0) {
return [activities count];
}
else {
return [feelings count];
}
}
</code></pre>
<p>and ....</p>
<pre><code>// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
activities = [[NSArray alloc] initWithObjects:@"Sleeping", @"eating", @"working", @"thinking", @"crying", @"begging", @"leaving", @"shopping", @"hello worlding", nil];
feelings = [[NSArray alloc] initWithObjects:@"awesome", @"sad", @"happy", @"ambivalent", @"nauseous", @"psyched", @"confused", @"hopeful", @"anxious", nil];
}
</code></pre>
<p>and....</p>
<pre><code>- (void)dealloc {
[activities release];
[feelings release];
[super dealloc];
}
</code></pre>
<p>i went into IB and right-clicked on the picker and dragged the dataSource to the files owner, just like the book told me
then when i ran it.. i got black screen then nothing.</p>
<p>heres my debugger</p>

How to integrate stripe using paymentIntent and confirmCardPayment
|
<p>I am attempting to integrate stripe into my application. I have completed the following steps so far.</p>
<ol>
<li>Ceate PaymentIntent on the server</li>
<li>Pass client secret to frontend</li>
<li><p>Use Stripe Elements to collect card info</p></li>
<li><p>Use Stripe.js handleCardPayment to process the payment</p></li>
</ol>
<p>During the handleCardPayment i am using react-stripe-elements and the documentation says to pass either the card element or the cardNumber element. <a href="https://stripe.com/docs/stripe-js/reference#stripe-confirm-card-payment" rel="nofollow noreferrer">https://stripe.com/docs/stripe-js/reference#stripe-confirm-card-payment</a></p>
<p>As you can see below im using <code>CardNumberElement, CardExpiryElement, CardCVCElement</code> separately. </p>
<pre><code> render() {
console.log(this.props.paymentIntent);
return (
<div className="checkout-component">
<br/>
<label>
Name:
<input placeholder="Name" />
</label>
<label>
Email:
<input placeholder="Email"></input>
</label>
<label>
Card Number:
<CardNumberElement ref={this.cardNumberRef}/>
</label>
<label>
Expiry Date:
<CardExpiryElement />
</label>
<label>
CVC:
<CardCVCElement />
</label>
<Grid
container
direction="column"
justify="center"
alignItems="flex-start"
spacing={5}
>
<Grid item>
<div>Total: {this.props.paymentIntent.amount / 100}</div>
</Grid>
<Grid item>
<Button variant="contained" color="primary" onClick={this.submit}>
Buy
</Button>
</Grid>
</Grid>
</div>
)
}
</code></pre>
<p>my submit function looks like the following: </p>
<pre><code>
submit = async () => {
try {
const data = {
payment_method: {
card: this.cardNumberRef.current.getElement(),
}
}
const result = await this.props.stripe.confirmCardPayment(this.props.paymentIntent.client_secret, data)
console.log(result);
} catch (err) {
console.log(err);
}
}
</code></pre>
<p>I opted not to use the card element instead using the individual pieces. </p>
<p>Although it succeeds, i am confused why i don't need to pass the cvc or expiry date?</p>

Why is my PayPal IPN script failing?
|
<p>I'm developing a lightweight e-commerce solution that uses <em>PayPal</em> as the payment gateway. However, my IPN callback is constantly returning an <code>INVALID</code> response. I even tried using the sample PHP script provided by <em>PayPal</em>:</p>
<pre><code>// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);
// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
if (!$fp) {
// HTTP ERROR
}
else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {
// check the payment_status is Completed
// check that txn_id has not been previously processed
// check that receiver_email is your Primary PayPal email
// check that payment_amount/payment_currency are correct
// process payment
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}
}
fclose ($fp);
}
</code></pre>
<p>But as I say, I keep getting an <code>INVALID</code> response. This is in fact the response I get using a PHP class that writes the response to a log file:</p>
<pre><code>[2011-06-02 19:18:49] - FAIL: IPN Validation Failed.

</code></pre>
<p>This is from the official <em>PayPal</em> IPN test tool. So something between <em>PayPal</em>'s sample code and test tool is causing my script to fail. Any one have any ideas?</p>

Managed Type equivalent of [MarshalAs(UnmanagedType.I8)]
|
<p>I have inherited a dll written in C that I access from a windows application (Framework 2.0) in C#. Recently some machines have been upgraded to 64-bit Windows 7, and the dll is no longer returning the correct values on those machines. I believe this is because the C function has parameter types that are expected to be 64-bit.</p>
<p>Here's the signature of the C function</p>
<pre><code>int doFlightCalc_S(double LatA,
double LonA,
double LatB,
double LonB,
int month,
int aircraftCd,
int nbrPsgrs,
int taxiInTm,
int taxiOutTm,
int fuelStopTime,
int *results)
</code></pre>
<p>Here's the definition that accesses the function from C#</p>
<pre><code>[DllImport("doFlightCalc.dll", CallingConvention = CallingConvention.Cdecl)]
private static extern int doFlightCalc_S(
[MarshalAs(UnmanagedType.R8)] double latA,
[MarshalAs(UnmanagedType.R8)] double lonA,
[MarshalAs(UnmanagedType.R8)] double latB,
[MarshalAs(UnmanagedType.R8)] double lonB,
[MarshalAs(UnmanagedType.I4)] int month,
[MarshalAs(UnmanagedType.I4)] int aircraftCd,
[MarshalAs(UnmanagedType.I4)] int nbrPsgrs,
[MarshalAs(UnmanagedType.I4)] int taxiInTm,
[MarshalAs(UnmanagedType.I4)] int taxiOutTm,
[MarshalAs(UnmanagedType.I4)] int fuelStopTime,
[MarshalAs(UnmanagedType.LPArray)] [Out] int[] results);
</code></pre>
<p>If I were to compile the C dll as a 64-bit dll while leaving the function as is, what changes would I need to make to the function in C#?</p>
<p>I would assume that I have to change the I4s to I8s but what type would I replace the int and double with? Would the following :</p>
<pre><code> [MarshalAs(UnmanagedType.R8)] double lonB,
[MarshalAs(UnmanagedType.I4)] int month,
</code></pre>
<p>be changed to:</p>
<pre><code> [MarshalAs(UnmanagedType.R8)] (what would go here?) lonB,
[MarshalAs(UnmanagedType.I8)] long (is long correct here?) month,
</code></pre>
<p>Or am I barking up the wrong tree?</p>

PySide: Drag and drop files into QListWidget
|
<p>This is my first entry here so apologies for any newbie mistakes. I've searched both here and Google with no luck before posting.</p>
<p>I want to be able to add images to a QListWidget, using drag and drop from a file browser. Dropping a valid file on the list widget also needs to trigger a function in the main class of my app, and pass it the image path. </p>
<p>I found <a href="https://stackoverflow.com/questions/4151637/pyqt4-drag-and-drop-files-into-qlistwidget">this code</a> that does exactly that, but for PyQt4. Importing QtCore and QtGui from PySide instead of PyQt4 produces a segmentation fault when triggering a drag and drop event. There are no error messages. </p>
<p>I think I've traced this to an old way of handling signals and have tried using the new, more pythonic way described <a href="https://qt-project.org/wiki/Signals_and_Slots_in_PySide" rel="nofollow noreferrer">here</a>. I can't seem to get it working, while still passing a list of URLs between classes however. </p>
<p>Any help would be greatly appreciated!</p>
<pre><code>import sys
import os
from PyQt4 import QtGui, QtCore
class TestListView(QtGui.QListWidget):
def __init__(self, type, parent=None):
super(TestListView, self).__init__(parent)
self.setAcceptDrops(True)

Fetch data from mysql database using drop down list and then use search function to filter data from selected drop down list option
|
<p>I want to comebine the use of a drop down list (with filters/options) with a search function (a search bar and a "Ok" button).</p>
<p>When I select a filter/option in the drop down list, as for example "Team". The drop down
list then should be aware of that the list has changed to filter/option "Team".
After this, I use the search function where I input the search term, like "USA" then press
the Ok-button.
Once the Ok-button is pressed, a sql-query like: SELECT * FROM mytable WHERE Team = 'USA';
is generated to fetch all the matched rows in the db "mytable".</p>
<ol>
<li>Select a filter, "Team".</li>
<li>Select a team, "USA".</li>
<li>Fetch matched rows with relevant data from the db mytable.</li>
</ol>

How to use multiple JPA persistence contexts with Spring Data JPA?
|
<p>I need two persistence contexts to manage entities in separate databases. </p>
<p>I am using java based config with spring 4.1.4, hibernate 4.3.7 and spring data 1.2. </p>
<p>Basically, CompanyApplicationContext imports two persistence contexts: PersistenceContext and SharedDbPersistenceContext. Each persistence context with its own data source, transaction manager and entity manager factory. The entities and jpa repositories for each persistence context are present in separate packages and are mentioned in persistence context class files.</p>
<p>I get this error:</p>
<pre><code>Not an managed type: class com.company.shared.model.ClientSetting

<p>What extra configuration do I need to do this to make it work? Why is each context not scanning and registering entities and repositories properly?</p>
<p>Main application context:</p>
<pre><code>package com.company.config;

Can I use parent-child relationships on Kibana?
|
<p>On a relational DB, I have two tables connected by a foreign key, on a typical one-to-many relationship. I would like to translate this schema into ElasticSearch, so I researched and found two options: the <a href="https://www.elastic.co/guide/en/elasticsearch/reference/1.3/mapping-nested-type.html" rel="noreferrer">nested</a> and <a href="https://www.elastic.co/guide/en/elasticsearch" rel="noreferrer">parent-child</a>. My ultimate goal was to visualize this dataset in Kibana 4.</p>
<p>Parent-child seemed the most adequate one, so I'll describe the steps that I followed, based on the official <a href="https://www.elastic.co/guide/en/elasticsearch/guide/current/index.html" rel="noreferrer">ES documentation</a> and a few examples I found on the web.</p>
<pre><code> curl -XPUT http://server:port/accident_struct -d '
{
"mappings" : {
"event" : {
},
"details": {
"_parent": {
"type": "event"
} ,
"properties" : {
}
}
}
}
';
</code></pre>
<p>here I create the index accident_struct, which contains two types (corresponding to the two relational tables): event and details.</p>
<p>Event is the parent, thus each document of details has an event associated to it.</p>
<p>Then I upload the documents using the bulk API. For event:</p>
<pre><code>{"index":{"_index":"accident_struct","_type":"event","_id":"17f14c32-53ca-4671-b959-cf47e81cf55c"}}
{values here...}
</code></pre>
<p>And for details:</p>
<pre><code>{"index":{"_index":"accident_struct","_type":"details","_id": "1", "_parent": "039c7e18-a24f-402d-b2c8-e5d36b8ad220" }}
</code></pre>
<p>The event does not know anything about children, but each child (details) needs to set its parent. In the ES documentation I see the parent being set using "parent", while in other examples I see it using "_parent". I wonder what is the correct option (although at this point, none works for me).</p>
<p>The requests are successfully completed and I can see that the number of documents contained in the index corresponds to the sum of events + types. </p>
<p>I can also query parents for children and children for parents, on ES. For example:</p>
<pre><code>curl -XPOST host:port/accident_struct/details/_search?pretty -d '{
"query" : {
"has_parent" : {
"type" : "event",
"query" : {
"match_all" : {}
}
}
}
}'
</code></pre>
<p>After setting the index on Kibana, I am able to list all the fields from parent and child. However, if I go to the "discover" tab, only the parent fields are listed.</p>
<p>If I uncheck a box that reads "hide missing fields", the fields from the child documents are shown as grey out, along with an error message (see image)</p>
<p><img src="https://i.stack.imgur.com/JjVl9.png" alt="enter image description here"></p>
<p>Am I doing something wrong or is the parent-child not supported in Kibana4? And if it is not supported, what would be the best alternative to represent this type of relationship?</p>

Why is XMLHttpRequest readystate not equal to 4?
|
<p>I'm learning AJAX for the first time and I'm trying to create a simple application that calculates the grade a person needs to get on their final exam based on their previous assessment results. </p>
<p>The user inputs their grades into the form and then using ajax I calculate the response in response.php which should then be output in the callback function in the div with ajax as its id. </p>
<p>For some reason the xhr.readystate property is never reaching 4 so the response is never generated. Can anybody see what I'm doing wrong?</p>
<p>Please bear in mind I'm only learning... </p>

<p>I need to do this via VBA. I can't get it to work for a .txt or .ini file. How can I check if a txt or ini file is already open by someone on the network?</p>
<p>Edit: It returns false for txt and ini files whether they are open or not.</p>
<p>If you are so inclined, I am attempting to build a distributive computing system on a clients network. I've never done this before and I am looking to keep it as simple as possible, so I was thinking of communicating via txt files. MSMQ looks good, but it looks like a long learning curve. I've already read all of the posts on stackoverflow regarding distributive computing.</p>

JPA dynamic criteria-api query

<p>I wonder if there is a generic way to use the criteria api in combination with a little more complex model?</p>

<p>I need to do a distinction of cases for filtering and sorting depending on the root/join on which I am accessing the property. Plus I need to use a naming convention in the facelet. The same goes for the <em>count</em>-query except for sorting.</p>
<p>Now I ask myself whether there is some "dot-notation" or anything which makes the case dispensable. In e. g. native SQL I would do something like create a subquery and select all alias values from the inner projection (<code>select * from (select person.name as name, address.street as street, ...) where name = ... and street like ...</code>).</p>
<p>I would be grateful for any advice.</p>

Symfony; SQLSTATE[HY000] [2002] No such file or directory while using 127.0.0.1 as database_host
|
<p>The full error is <code>Doctrine\DBAL\Exception\ConnectionException: An exception occurred in driver: SQLSTATE[HY000] [2002] No such file or directory in /app/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/AbstractMySQLDriver.php on line 113</code>, but that's too long for the title.</p>
<p>I'm trying to set up a Symfony project locally, but I'm struggling to get the database connection to work. My <code>parameters.yml</code> looks as follows</p>
<pre><code>parameters:
database_host: 127.0.0.1
database_port: 3306
database_name: database_name
database_user: username
database_password: password
</code></pre>
<p>I've been googling this issue a lot and most people seem to solve the issue by changing <code>database_host</code> from <code>localhost</code> to <code>127.0.0.1</code>, but this doesn't work for me. The app itself runs via Docker, but I've set up the database connection once via Brew and once with a MySQL server for Mac. In both cases I can connect via the command line and with SequelPro/TablePlus, but whenever I try to access the website through the browser I get the "No such file or directory" error.</p>
<p>I've also tried multiple ways of setting up a Docker MySQL container, but can't get it to work. My <code>docker-compose.yml</code> looks like this;</p>
<pre><code>nginx:
build: nginx
ports:
- "8080:80"
links:
- php
volumes:
- ../:/app
php:
build: php-fpm
volumes:
- ../:/app
working_dir: /app
extra_hosts:
- "site.dev: 172.17.0.1"
services:
db:
image: mysql:5.7
restart: always
environment:
MYSQL_DATABASE: 'database_name'
MYSQL_USER: 'username'
MYSQL_PASSWORD: 'password'
MYSQL_ROOT_PASSWORD: 'password_root'
ports:
- '3306:3306'
expose:
- '3306'
volumes:
- my-db:/var/lib/mysql
</code></pre>
<p>But whenever I run <code>docker-compose up -d</code> I get the error <code>Unsupported config option for services: 'db'</code>.</p>
<p>Another attempt was adding</p>
<pre><code>mysql:
image: mysql:latest
volumes:
- mysql_data:/var/lib/mysql
environment:
- MYSQL_ROOT_PASSWORD='password'
- MYSQL_DATABASE='database_name'
- MYSQL_USER='username'
- MYSQL_PASSWORD='password'
</code></pre>
<p>To the docker-compose file, and while it does build the mysql image, I can't seem to connect to it with SequelPro/TablePlus. I ran <code>docker-inspect</code> on the container to get the IP (172.17.0.3), but can't seem to get access to it. I can <code>exec</code> into it, login using <code>mysql -u root</code> and create the required user and database, but then I'm still struggling to actually connect to it.</p>
<p>Running <code>docker ps</code> does show the sql container running btw;</p>
<pre><code>CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
b6de6030791d docker_nginx "nginx -g 'daemon of…" 19 minutes ago Up 14 minutes 0.0.0.0:8080->80/tcp docker_nginx_1
f26b832bb005 docker_php "docker-php-entrypoi…" 19 minutes ago Up 14 minutes 9000/tcp docker_php_1
6c2a9e657435 mysql:latest "docker-entrypoint.s…" 19 minutes ago Up 14 minutes 3306/tcp, 33060/tcp docker_mysql_1
</code></pre>
<p>I also thought it might be an issue with changes to the <code>parameters.yml</code> file not properly syncing with the container as I'm using Mac (at my old workplace we had to use docker-sync to make sync changes between our dev environment and the actual container), but when inspecting the container itself using <code>exec</code> I can see the changes in the <code>parameters.yml</code> file.</p>
<p>Could the issue be it trying to connect to a mysql server running outside the Docker container? I'm still very new to Docker so I wouldn't be surprised if that's the mistake. Any tips are appreciated 'cause I'm at a dead end.</p>

<p>To build my update msi and bootstrapp I set greater (the same for msi and bootstrapp) product version, for example old version has 1.0.0.0 and newer has 1.0.1.0. Upgrade code as a WIX documentation says remains unchanged. After run my update installer the new version of msi is not installig, in install directory still are old files. Does anyone know what I do wrong?</p>
<p>@Edit
Also I tried by adding MajorUpgrade element but after that bootstrapper doesn't start MSI:</p>
<pre><code><Media Id="1" Cabinet="contents.cab" EmbedCab="yes" CompressionLevel="high"/>
<MajorUpgrade Schedule="afterInstallInitialize" DowngradeErrorMessage="A later version of [ProductName] is already installed. Setup will now exit."/>
<Directory Id="TARGETDIR" Name="SourceDir"/>

When using the float:left function, I get all the li aligned horizontally, but in this case, I cannot center it on the page. Also the margin:0 auto; does not do it in this case.</p>
<p>The navigation bar is created via an ul inside a DIV, which is also contained inside a "wrapper div".</p>
<p>Is the problem linked to the various ID selectors used and the nesting of the various elements? </p>
<p>Please find the jsfiddle below for visualisation:</p>

prevent php mail sent going to spam gmail

<p>this is my complete code that I use to send emails from a contact form on a website.
Despite all the best practices used (headers etc), the results are:</p>
<p>1) the confirmation email to users goes in gmail spam every time and it is flaged as phishing</p>
<p>2) the admin email is flagged as phishing</p>

C#.NET Using isAuthenticated
|
<p>Im using the MVC format to create a website. Right now all it does is manage users from an SQL server. What i'm trying to do now is have the user log in and then be able to manage the Users. From the Login page it should go to the Index of the Account but I only want this page to be viewable by authenticated users. It works fine if I: </p>
<p>1)set the function in the controler to [AllowAnonymous] (This is not what i want)</p>
<p>2)Allow Windows Authentication (Which is not what I want because once I deploy, it'll be on the web)</p>
<p>It really just boils down to how do I authenticate a user and then have that authentication persist. </p>
<p>Here is the login page:</p>
<pre><code>@model myWebsite.Models.LoginModel
@{
ViewBag.Title = "Login";
ViewBag.ReturnUrl = "Index";

<h2>Login</h2>
@using (Html.BeginForm("Login", "Login", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" }))
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
<h4>Login</h4>
<hr />
@Html.ValidationSummary(true, "", new { @class = "text-danger"})

jQuery Roundabout: changing the number of items shown

<p>I am using the jQuery Roundabout plugin. I am wondering if there is a way to choose the number of pictures that are shown. I have ten pictures, but only three of them should be visible as shown in the second (extention) link within the "square" example.</p>

C# technique for deleting a file from web server immediately after closing
|
<p>I'm creating PDF invoices in a C# MVC application that I'm attaching to an email and sending, ideally, once the email is sent I'd like to delete the invoice to free up server space and improve privacy/security. I've written code to do it but it fails 50% of the time because the file is locked by another process (I'm not sure if it's the create/write process that's locking it or the email send). I'm sending the email asynchronously (i.e. the code to delete doesn't execute until the email has sent).</p>
<p>I'd appreciate some tips on how to handle this problem. I could run a job to clean up old files but I'd prefer to clean them up as I go...</p>
<p>I forgot to mention I am using iTextSharp to generate the PDF - the crux of it is this code is used to generate the final invoice (I am able to delete the list of files passed in as a param without drama):</p>
<pre><code>/// <summary>
/// http://stackoverflow.com/questions/4276019/itextsharp-pdfcopy-use-examples
/// </summary>
/// <param name="fileNames"></param>
/// <param name="outFile"></param>
private void CombineMultiplePDFs(List<string> files, string outFile)
{
int pageOffset = 0;
int f = 0;
iTextSharp.text.Document document = null;
PdfCopy writer = null;
foreach (string file in files)
{
// we create a reader for a certain document
PdfReader reader = new PdfReader(file);
reader.ConsolidateNamedDestinations();
// we retrieve the total number of pages
int n = reader.NumberOfPages;
pageOffset += n;
if (f == 0)
{
// step 1: creation of a document-object
document = new iTextSharp.text.Document(reader.GetPageSizeWithRotation(1));
// step 2: we create a writer that listens to the document
writer = new PdfCopy(document, new FileStream(outFile, FileMode.Create));
// step 3: we open the document
document.Open();
}
// step 4: we add content
for (int i = 0; i < n; )
{
++i;
if (writer != null)
{
PdfImportedPage page = writer.GetImportedPage(reader, i);
writer.AddPage(page);
}
}
PRAcroForm form = reader.AcroForm;
if (form != null && writer != null)
{
writer.CopyAcroForm(reader);
}
f++;
}
// step 5: we close the document
if (document != null)
{
document.Close();
}
}
</code></pre>
<p>The PDF File is then sitting on the server (e.g. "~/Invoices/0223.pdf") ready to attach to an email like so:</p>
<pre><code>MailMessage mailMessage = new MailMessage();
mailMessage.From = new MailAddress(WebConfig.GetWebConfigKey(AppSettingsKey.ReplyEmailAddress.ToString()));
mailMessage.To.Add(new MailAddress(user.Email));
mailMessage.Subject = emailTemplate.TemplateSubject;
mailMessage.Body = emailTemplate.TemplateContent;
mailMessage.IsBodyHtml = false;
mailMessage.Attachments.Add(new Attachment(HttpContext.Current.Server.MapPath("/Invoices/" + invoiceId + ".pdf")));
SmtpClient client = new SmtpClient();
try
{
client.Send(mailMessage);
}
catch{...}{
//Error handling
}
client.Dispose();
</code></pre>
<p>Then I attempt to delete it:</p>
<pre><code>File.Delete(HttpContext.Current.Server.MapPath("/Invoices/" + invoiceId + ".pdf"));
</code></pre>

How to handle ECONNRESET when proxied response includes `connection: close` header?
|
<p>I am attempting to implement a MITM proxy.</p>
<p>I am handing a CONNECT request which is then used to create a connection with an internal HTTPS server.</p>
<p>Upon request, HTTPS server responds with:</p>
<pre><code>connection: close
foo
</code></pre>
<p>I expect the client to receive the response and proxy to close the connection socket.</p>
<p>Instead, <code>client</code> receives the response and proxy server logs an error:</p>
<pre><code>server socket error Error: This socket has been ended by the other party

<p>Alternatively, you can:</p>

jQuery Expanding & Collapsing lists
|
<p>The code expands and collapses a list in which list items can have sublists. Any ideas to refactor this code - especially the toggling part. Is it necessary to use closures here ? </p>
<pre><code>$(function()
{
$('li:has(ul)')
.click(function(event){
if (this == event.target)
{
var that = this;
$('li:has(ul)').children().filter(':not(:hidden)').parent().each(function(x){
if(this != that)
toggleList(this);
});
toggleList(this);
}
})
.css({cursor:'pointer', 'list-style-image':'url(plus.gif)'})
.children().hide();
$('li:not(:has(ul))').css({cursor: 'default', 'list-style-image':'none'});
});
function toggleList(L)
{
$(L).css('list-style-image', (!$(L).children().is(':hidden')) ? 'url(plus.gif)' : 'url(minus.gif)');
$(L).children().toggle('fast');
}
</code></pre>
<p><strong>EDIT:</strong></p>
<p>The script works on the following HTML snippet (source: jQuery in Action). Actually I was trying to extend the script given in the book. </p>
<pre><code> <ul>

Radio Buttons getting deselected when dragging item using jQuery Sortables
|
<p>I'm using the <a href="http://docs.jquery.com/UI/Sortables" rel="noreferrer">jQuery UI sortables</a> plugin to allow re-ordering of some list items. Inside each list item, I've got a couple of radio buttons which allow the item to be enabled or disabled.</p>
<p>When the item is dragged, both radio buttons get deselected, which doesn't seem like it should be happening. Is this correct behavior, and if not, what is the best way to work around this?</p>
<p>Here is a code sample demonstrating this problem:</p>
<pre><code><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<input name="status_4" type="radio" value="0" />disabled
</li>
</ol>
<script type="text/javascript">
$('#itemlist').sortable();
</script>
</body>
</html>
</code></pre>
<p>As soon as a list item is grabbed with the mouse, both the radio buttons get deselected.</p>
<p>If this is a bug, one workaround would be to automatically select the 'enabled' radio button when the item is moved, so any advice on how to achieve this would also be most appreciated.</p>
<p>Update: I've tested this in FireFox 3, Internet Explorer 7, Opera 9.5, and Safari 3.1.2, all on Windows XP x64, and this issue occurs in all of them.</p>

Panel data fixed effect issue with R, I don't see my all dummy variables in the summary

<p>I'm running a data panel regression with R.
I use those <a href="https://docs.google.com/spreadsheets/d/1fXzrKS0ABn-ygKWnGhKskmoCLNikZCsY_u1yu08uSq4/edit?usp=sharing" rel="nofollow noreferrer">data</a>(sheet 2).</p>

In .Net Core 2.1 Web API for PUT and DELETE only why "No 'Access-Control-Allow-Origin' header is present on the requested resource"

<p>I am using .NET Core 2.1. I have configured Startup.cs as follow: </p>
<pre><code>public class Startup
{
public static IConfiguration Configuration { get; private set; }
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public void ConfigureServices(IServiceCollection services)

}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseCors(builder => builder.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseMvc();
}
}
</code></pre>
<p>Web API is deployed on linux machine. <code>GET</code> and <code>POST</code> methods are working fine. When I try to call <code>PUT</code> or <code>DELETE</code> this message is being generated in <code>Chroome</code> console. </p>
<p><code>Access to XMLHttpRequest at 'http://IP' from origin 'http://IP' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.</code> </p>
<p>Initially Kestrel was listing on <code>50001</code> beacuse SSL certificate was present. I configured Kestrel in <code>appsettings.json</code> to listen only on <code>5000</code>. So now its only listing on <code>5000</code>.</p>

Deserialize Json to class object using restsharp
|
<p>I have checked out the documentation for restsharp and also googled for a solution, but unable to find a solution for this problem:</p>
<p>I have an asp.net mvc3 app and need to connect to quizlet.com to access public flashcards. I have added a reference to restsharp and created the following classes:</p>
<pre><code>public class QuizletObject
{
public string response_type { get; set; }
public int total_results { get; set; }
public int page { get; set; }
public int total_pages { get; set; }
public int sets_with_images { get; set; }
public Set[] sets { get; set; }
}
public class Set
{
public int id { get; set; }
public string title { get; set; }
public string url { get; set; }
public string creator { get; set; }
public int created { get; set; }
public int term_count { get; set; }
public bool has_images { get; set; }
public int last_modified { get; set; }
}
</code></pre>
<p>I have a class and method that calls the web service like this:</p>
<pre><code>public class Quizlet
{
private string _baseUrl = "http://api.quizlet.com/1.0/sets";
private const string DevKey = "my dev key";
public QuizletObject GetQuizletSets()
{
_baseUrl = _baseUrl + "?dev_key=" + DevKey + "&q=" + "geography";
RestClient client = new RestClient();
client.BaseUrl = _baseUrl;
RestRequest request = new RestRequest(Method.GET);
request.RequestFormat = DataFormat.Json;
RestResponse<QuizletObject> response = client.Execute<QuizletObject>(request);
return response.Data;
}
}
</code></pre>
<p>When I try to access the method using the below code in the view, I get a <strong>NullReference exception (Object reference not set to an instance of an object).</strong></p>
<pre><code>@{
QuizletObject quizletObject = quizlet.GetQuizletSets();
}
@foreach (Set quizletSet in quizletObject.sets)
{
@quizletSet.id.ToString()
<br />
@quizletSet.title
<br />
@quizletSet.creator
<br />
@quizletSet.created
<br />
@Html.Encode(quizletSet.url)
<br />
<br />
}
</code></pre>
<p>If the same method is executed as below, it returns the complete json object without any problem</p>
<pre><code>RestResponse response = client.Execute(request);
</code></pre>
<p>Stack trace:</p>
<pre><code>[NullReferenceException: Object reference not set to an instance of an object.]
