329,068 | 329,069 | VNC SERVER source/app for non-jailbroken iPhone? | <p>I have looked and looked and cannot find an answer. I am looking for an open source vnc <strong>server</strong> for the iphone. I would like to deploy it to my device, and not install it via jailbreaking/cydia. [I'm not looking for a tv-out option (I know that exists), nor a VNC client. Also not looking for screen mirroring (http://code.google.com/p/iphoneos-screen-mirroring/).]</p>
<p>Alternate approach: If you KNOW one doesn't exist at the moment: I know veency is out there to be downloaded through Cydia, and I could use something like iResign to sign the ipa with my dev certificates but if I have to go this route how would I get the ipa and it's dependencies without jailbreaking? And could the dependency debs even be installed with iResign?</p>

<pre><code>//This is the directory where images will be saved
$uploadDir = "./";
$uploadFile = $uploadDir . basename( $_FILES['photo']['name']);

Console.WriteLine("The value of 'x' is " + x);

This is all using the new <code>CursorLoader</code> support from the v4 compat library. Everything is working (finally!) but when I return from the Edit, the changes are not showing up in the list.</p>
<p>I suspect this is due to the cursor just being reloaded upon resuming the "List" activity and perhaps since it is a separate activity it does not receive any "update" notification from the edit Activity? All the database updates are doing notification as:</p>

2,628,428 | 2,628,429 | How to use JQuery 'on()' with class selector filter? | <p>Trying to update some old code from <code>live()</code> to use <code>on()</code> and something is failing miserably.</p>
<pre><code>$('#accordion').on('click','.EditModeDetails', function(event){
alert('yay');
});
</code></pre>
<p>where <code>.EditModeDetails</code> is a class on injected HTML like so:</p>
<pre><code><li class="instructionText">
<input value="EditModeDetails" class="EditModeDetails" name="EditModeDetails" type="checkbox">
<label for="EditModeDetails">Edited text replaces existing text. To add new text, check this box </label>
</li>
</code></pre>
<p>...and <code>#accordion</code> is an accordion control that is loaded at page load.</p>
<p>If I remove the filter, thus:</p>
<pre><code>$('#accordion').on('click', function(event){
alert('yay');
});
</code></pre>
<p>....I get alerts all over the place.</p>
<p>Have looked all over for a sample that uses a class instead of an element selector and having no luck.</p>
<p>EDIT: Many thanks for the suggestions, guys, but nothing is working thus far The version of JQuery that is loaded is ver--1.7.1. Here is the link to the actual development:</p>
<p><a href="http://esc.toypizza.com/sysalert" rel="nofollow">http://esc.toypizza.com/sysalert</a></p>
<p>To see the problem, in the datatable click on <img src="http://esc.toypizza.com/_img/details_open.png"> followed by clicking on the <img src="http://esc.toypizza.com/_img/up_arrow.png"> that appears. Next, click on the accordion section "Details" (above the "Current Issues" section that opens as the default). You will see the offending checkbox to the right of the "Clear" button.</p>

<p>Will PHP just make <code>$countries</code> <em>point</em> to the literal data in memory or will it <em>copy over</em> all the initialization data to a new ZVAL or whatever?</p>

<p>It seems to try and do a bit of clean-up (it's awful when you have to work with regular expressions), but on the other hand function naming and parameter constants seem to be a disaster, if you ask me. It must have been included in PHP for a reason, but I just don't seem to like it. What am I missing?</p>
<p><i>Later edit:</i><br />
Regarding GaryF's answer, I wish to explain a bit why I don't like this function.
This isn't about using it in "my case" if it fits. This is about using it wherever it fits. There's a high chance of needing a filter that won't fit PHP's functions, so I'll have to create my own filter. In that case, the application will use two completely different kinds of functions for data filtering. I consider that to be a much worse practice than just inventing a better wheel.</p>

<p>Here is my Message Object. I only want one object allowed per element. The element noted in the comments. </p>
<p>As the user sees it, there should be only one message per element. If the user keeps clicking a button for example I don't want to re-instantiate more messages. Only one is needed. </p>
<p>One thing I could have done is disabled buttons until the message is finished being displayed...but that is just not the way I want to go.</p>
<p>The Effects.fade() function fades out the message after about 4 seconds.</p>
<p><strong>Question?</strong></p>
<p>How do I modify this so it only allows one instance of itself per element?</p>
<p><strong>The Object</strong></p>
<pre><code>/**
* Message
*/
var Message = function( element )
{
// need only single instance per element..so a singleton pattern per element
this.element = element; // This is element where the message is sent
};
Message.prototype.messages =
