In fact, I cannot remember how I can get the content of the page as a string, so I can apply a regular expression to find what I want. Can you please help me on this?</p>
<p>Before anyone suggests it, I cannot use getElementBy(Id/Name/Tag), because the data I'm looking for is HTML-commented and inside markups, so I don't think that would work.</p>
<p>Thanks.</p>

2,668,893 | 2,668,894 | Good patterns for loose coupling in Java? | <p>I'm new to java, and while reading documentation so far i can't find any good ways for programming with loose coupling between objects. For majority of languages i know (C++, C#, python, javascript) i can manage objects as having 'signals' (notification about something happens/something needed) and 'slots' (method that can be connected to signal and process notification/do some work). In all mentioned languages i can write something like this:</p>
<pre><code>Object1 = new Object1Class();
Object2 = new Object2Class();
Connect( Object1.ItemAdded, Object2.OnItemAdded );
</code></pre>
<p>Now if <code>object1</code> calls/emits <code>ItemAdded</code>, the <code>OnItemAdded</code> method of <code>Object2</code> will be called. Such loose coupling technique is often referred as 'delegates', 'signal-slot' or 'inversion of control'. Compared to interface pattern, technique mentioned don't need to group signals into some interfaces. Any object's methods can be connected to any delegate as long as signatures match ( C++Qt even extends this by allowing only partial signature match ). So i don't need to write additional interface code for each methods / groups of methods, provide default implementation for interface methods not used etc.</p>
<p>And i can't see anything like this in Java :(. Maybe i'm looking a wrong way?</p>

690,761 | 690,762 | Help to Install Eclipse for A Netbeans Users | <p>I had been using Netbeans all the while to develop Swing application. So far, I am a <strong>Happy Netbeans User</strong></p>
<p>Currently, I had a project (GWT, J2EE and Swing), which I need to use Eclipse (Please do not ask Why)</p>
<p>Here is the step I had been taken.</p>
<ol>
<li>Download <em>Eclipse IDE for Java EE Developers (190 MB)</em> from <a href="http://www.eclipse.org/downloads/" rel="nofollow">http://www.eclipse.org/downloads/</a> I thought this should be the correct choice, as I see most features are found in that edition <a href="http://www.eclipse.org/downloads/packages/compare-packages" rel="nofollow">http://www.eclipse.org/downloads/packages/compare-packages</a></li>
<li>After struggling a while to get use to the user interface of Eclipse, I still cannot find a <strong>Visual GUI Editor</strong>!</li>
<li>After doing some Googling, I realize I need to install something called <strong>Plugins</strong></li>
</ol>
<p>However, tones of plugins which had similar features has confused me, as I found</p>
<p><a href="http://www.cloudgarden.com/jigloo/index.html" rel="nofollow">http://www.cloudgarden.com/jigloo/index.html</a></p>

<p><a href="http://code.google.com/p/visualswing4eclipse/" rel="nofollow">http://code.google.com/p/visualswing4eclipse/</a></p>
<p>This makes me even more confuse? Which plugin I should use to develop a Swing based application? Most of them seems not up-to-dated. Or, is there any complete bundle I can download, where 1 click, will install all the necessary Swing development tools for me?</p>
<p><strong>I just miss my Netbeans :( I really appreciate their team, who make the installation work so easy. One click button install, all the necessary tools just come to me</strong></p>

583,468 | 583,469 | Open an url in android browser, avoid multiple tabs | <p>My project is mostly a web application. Now I have an android app with a home screen widget and would like to open a web page in the built-in browser on some user actions. That is easy. In MyAppWidgetProvider.onUpdate I create a new intent:</p>
<pre><code>Intent intent = new Intent("android.intent.action.VIEW",
Uri.parse("http://my.example.com/"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
views.setOnClickPendingIntent(R.id.text, pendingIntent);
</code></pre>
<p>Unfortunately, a new browser window/tab is opened every time the user clicks the widget. My page contains some fancy AJAX/javascript running in the background and regularly sending http requests. So I end up having 8 tabs containing the same page and continuously sending 8-fold amount of http requests.</p>
<p>Is there any way, e.g. different action or additional parameters to avoid opening new tabs?</p>
<p>As a workaround I am now thinking about creating a new activity containing a WebView, but would like to avoid this complexity.</p>

1,508,047 | 1,508,048 | Efficient data structure for Zobrist keys | <p>Zobrist keys are 64bit hashed values used in board games to univocally represent different positions found during a tree search. They are usually stored in arrays having a size of 1000K entries or more (each entry is about 10 bytes long). The table is usually accessed by <code>hashKey % size</code> as index. What kind of STL container would you use to represent this sort of table? Consider that since the size of the table is limited collisions might happen. With a "plain" array I would have to handle this case, so I thought of an unordered_map, but since the implementation is not specified, I am not sure how efficient it will be while the map is being populated. </p>

3,789,257 | 3,789,258 | extending the jquery .each loop | <p>I have a jQuery function that finds all the images nested in a container DIV with the ID of #popupForm, looks at the SRC attribute and compares it to a hidden input that has it's value created by a server side variable. Once rendered if there's a match it'll do a replace on the SRC of the image, hense:</p>
<pre><code>var thisTheme = $("#hiddenTheme").val();
var defaultTheme = "/midway/firstTheme/"
$('#popupForm img').each(function () {
var thisSRC = $(this).attr('src');
if (thisSRC.indexOf(defaultTheme) !== -1) {
var new_src = $(this).attr('src').replace(defaultTheme, thisTheme);
$(this).attr('src', new_src);
}
});
</code></pre>
<p>Now this works great but I wish to extend the loop part of this code (the .each part) so not only does it look at images in the container DIV but all inputs (yes some of the inputs have a SRC attribute - please don't ask why)</p>
<p>I was thinking of adding an array like such </p>
<pre><code>var arrValues = ["#popupForm img", "#popupForm input"];

<p>and then chaning the selector partof the each to contain the array, something like this</p>
<pre><code>$(arrValues).each(function () {

A lot of page updates are done via Prototype's Ajax.Updater. However, sometimes the elements that Prototype removes and replaces have had a jQuery widget run on them, so $.cache has references to the additional elements created by the widget. Since jQuery isn't doing the DOM removal, it doesn't have a chance to clear the data from $.cache for those elements when they are removed, and I end up with a memory leak. Is there a way to tell jQuery to check it's $.cache and discard any data for elements that are no longer in the DOM?</p>

var image_number = 0;
function ImageArray (n) {

return(image[image_number])
}
document.write("<img src='" + imlocation + randomimage()+ "'>");

</code></pre>
<p>and then repeated again using different variables so both images are random. I need the sizes of both images to be the same. CSS doesn't seem to be doing the trick using .img and specifying the height and width. Is there another way I could do it?</p>

<pre><code>var env = endPoint.replace("https://support.", "\n");
var envClean = env.replace(".mysite.com/batch/", "\n");

<p>I don't like repeating myself. I would like to look for both patterns in the string and remove them all at once.

<p>I've tried this:</p>
<pre><code>var env = endPoint.replace("https://support." && ".mysite.com/batch/", "\n");
</code></pre>
<p>but it just parses the second arg and disregards the first. </p>
<p>Does anyone have a cleaner way of doing this? I'm assuming I can search for multiple patterns via REGEX, any REGEX masters out there care to help?</p>

5,925,153 | 5,925,154 | Get current height of element by id | <p>I have an element as follows</p>
<pre><code><div id="loadNavigation" style="width:20%"></div>
<div id="loadContent" style="width:80%"></div>
</code></pre>
<p>Essentially navigation is on the left, content on the right.</p>
<p>Now I am dynamically resizing both <code>loadContent</code> and <code>loadNavigation</code> on page load to be at a minimum height of the browsers window height. Though at points more likely then not one of the div's will exceed the other in length if it exceeds window height. To prevent this from happening as an example I want to increase <code>loadNavigation</code> to the same size as <code>loadContent</code> by getting the height value of <code>loadContent</code>.</p>
<p>So far I have tried:</p>
<pre><code>function resizeAppWindow() {
var windowHeight = getWindowHeight();
var contentElement = document.getElementById("content");
var contentHeight = (windowHeight - 25);
contentElement.style.minHeight = contentHeight + "px";
var currentContentHeight = contentElement.style.height;
var navigationElement = document.getElementById("navigation");
var differenceInHeight = currentContentHeight - windowHeight;
var navigationHeight = (windowHeight + differenceInHeight);
navigationElement.style.minHeight = navigationHeight + "px";
}
</code></pre>
<p>But <code>currentContentHeight</code> will return null. I beleive this is because the element has a <code>style="min-height:00px;"</code> but not an actual defined height?</p>
<p>Any pointers in the right direction would be appreciated.</p>

1,049,820 | 1,049,821 | Subprocess in C# Application pauses unexpected | <p>I'm currently working on a service (well at this point it's still a Console Application, as this is a lot easier to debug). The basic task of this service is to watch a folder for new *.tif Files. As soon as the Application found a .TIF file in the folder it starts another Application with the following code:</p>
<pre><code>ProcessStartInfo command = new ProcessStartInfo(commandPath, commandParams);
command.RedirectStandardOutput=true;
command.UseShellExecute=false;
command.CreateNoWindow=true;
Process process = new Process();
process.startInfo = command;
process.Start();
process.WaitForExit();
</code></pre>
<p>This console application then uses IrfanView to split the Multipage-TIF into multiple singlepage-TIF (I use basically the same code as above to do this). After that, I check for a Barcode on the Scanned image (with zxing library). The found Barcode is then compared to the Oracle Database. Afterwards the file is converted to PDF and moved to a specific location, based on the found Barcode.</p>
<p>This console Application works perfectly, when I start it myself, but as soon as the "service" starts it, it will pause after a while and don't do anything until I close the "service"-console application. Then it finishes normally.</p>
<p>What could be the problem?</p>
<p>I tried to disable the Oracle, DB check and it worked. Afterwards I disabled my Logging class and it worked too. So my guess is, that I somehow use too much ressources or something like that. But where to start?</p>
<p><strong>EDIT:</strong>
Some additional information. I just debugged the process, as VS is able to attach to a process to debug. The command that hangs is Console.WriteLine (called from within the Console application which is called by my "service" console. Any way that a console in a subprocess can only have a certain amount of lines/chars? can a console-output stream have a deadlock or what is this?</p>
