<p>My questions:</p>

<li>Can registerForContextMenu() wait
until onFinishInflate()?</li>
<li>If so, how do I do so?</li>

664,895 | 664,896 | php sorted array and readfile not reading in order | <p>I am trying to write a php function to save and then display comments on an article.</p>
<p>In my save.php, I am formulating the file with:
<code>$file = "article1/comments/file".time().".txt";</code></p>
<p>Then using fwrite() to write to a directory. </p>
<p>In my index I have:</p>
<pre>
if ($handle = opendir('article1/comments')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
$files = array($file);
sort($files);
foreach($files as $comments){
echo "<div class='message'>";
readfile('article1/comments/'.$comments);
echo "</div>";
}
}
}
closedir($handle);
}
</pre>
<p>For the most part this displays the comments in the correct order, but for some reason, some files are displaying out of order. Furthermore, if I change sort() to rsort(), there is no change in how they are displayed.</p>
<p>I presume this is because readfile() is not following the sorted array's order. So I am wondering for one, why readfile does not display the files in order from newest to oldest, and two, how can I make it display them correctly?</p>
<p>Thanks.</p>
<p>edit: I copied the directory of comments from the live site to my local xampp installation, and the comments are displayed in order locally, but using the same code on my site results in comments not being in order.</p>

I have written a javascript method to convert an ip-address as string to an integer. I get some strange results however.</p>
<p>Here is my code:</p>
<pre><code>function ipToInt(ip) {
var parts = ip.split(".");
var res = 0;
res += parseInt(parts[0], 10) << 24;
res += parseInt(parts[1], 10) << 16;
res += parseInt(parts[2], 10) << 8;
res += parseInt(parts[3], 10);
return res;

<p>When I run call the method as <code>ipToInt("192.168.2.44");</code> the result I get is <code>-1062731220</code>.
It seems like an overflow has occurred, which is strange, because the expected output <code>(3232236076)</code> is inside the number range in javascript (2^52).</p>
<p>When I inspect <code>-1062731220</code> in binary form, I can see the <code>3232236076</code> is preserved, but filled with leading 1's.</p>

After talking with him, it got me interested in what people may think the "current" benchmark for the skills a developer should have out in the field to some degree.</p>

<li>jQuery (or similar framework)</li>
<li>CSS</li>
<li>Web standards for cross browser compatibility</li>

<p>This seems simple enough, but if you launch the app, rotate your device a few times, and then dump an hprof to view it in MAT or something similar, you'll see two things:</p>
<p>First, there are <strong>two</strong> instances of WebViewTestActivity hanging around, and <strong>two</strong> instances of WebView. This seems to be the case no matter how many times you rotate your device.</p>
<p>This seems like a huge problem, leaking an entire Activity, and I've googled it to no avail. I see several complaints about this issue, but no official responses or workarounds. </p>
<p>Can anyone shed some light on this?</p>

5,632,109 | 5,632,110 | PHP Error handling | <p>Thank you one and all ahead of time.</p>
<p>I am currently in the process of tweaking/improving a MVC framework I wrote from scratch for my company. It is relatively new, so it is certainly incomplete. I need to incorporate error handling into the framework (everything should have access to error handling) and it should be able to handle different types and levels of errors (User errors and Framework errors). My question is what is the best way and best mechanism to do this? I know of PHP 5 exception handling and PEAR's different error mechanism, but I have never used any of them. I need something efficient and easy to use. </p>
<p>Would it be better to create my own error handling or use something already made? Any suggestions, tips, questions are certainly welcomed. I would ultimately think it sweetness to somehow register the error handler with PHP so that I would just need to throw the error and then decide what to do with it and whether to continue.</p>
<p>EDIT: Sorry, I should of provided a more details about what type of errors I wanted to log. I am looking to log 2 main types of errors: User and Framework. </p>
<p>For user errors, I mean things like bad urls (404), illegal access to restricted pages, etc. I know I could just reroute to the home page or just blurt out a JavaScript dialog box, but I want to be able to elegently handle these errors and add more user errors as they become evident. </p>
<p>By Framework errors I means things like cannot connect to the database, someone deleted a database table on accident or deleted a file somehow, etc.</p>
<p>Also, I will take care of development and live server handling.</p>

<p>I have used the code from here <em><a href="http://www.bobpowell.net/addframes.htm" rel="nofollow">Adding frames to a Multi-Frame TIFF</a></em> and just changed a few bits so that it suits my application.</p>
<p>The problem is that the images are not legible as the size of the loaded image is too small.</p>

<p>When I have looked in to this the picture box seems to want you to name a file - as the file is the whole multipage image. This isn't right.</p>
