<p>I have investigated this problem and did not found any answers that exactly match my problem. Those answers were focused on the "popen" subroutine, but I do not use this routine. I just use the "<code>commands.getoutput()</code>" to display the file type of a document.</p>
<p>It should be noted that if I try to process a 10 million line text, this problem does not happen. It only happens when the text file is large.
Can any people help me out on this issue? The answer could be a better module other than the "<code>command.getoutput()</code>". Thanks!</p>

<pre><code>$(function(){

</code></pre>
<p>This is applied to a CSS/jQuery menu, which expands and contracts when each menu item is hovered over. The onClick event adds a <code>margin-top of 6px</code> to give the impressions of a button depress. </p>
<p>I'm then using PHP to detect which page the user is visiting to add an <code>.active</code> class to the relevant menu item.</p>
<p>The question, the .active class should remain in place <strong>until</strong> the user hovers over a different menu item. At which point the <code>.active</code> class should be removed from this element - As the <code>.active</code> class is reused on the <code>.hover</code> events.</p>
<p>Here is the basic HTML Markup:</p>
<pre><code><ul id="menu">
<li>
<div class="inner">
<div class="button"><img src="images/insightbutton.png" /></div>

So, for example in the code below I'm interested in the field being 10dip tall.</p>
<pre><code><EditText
android:id="@+id/frame0"
android:width="100dip"
android:singleLine="true"
android:inputType="phone"
android:maxLength="4"
android:textStyle="bold"
android:paddingLeft="10dip"
android:paddingRight="10dip"
android:textSize="8dip"
android:height="10dip"
android:maxHeight="10dip"
android:paddingTop="0dip"
android:paddingBottom="0dip"
android:gravity="center"
android:layout_gravity="center"
/>
</code></pre>
<p>[EDIT 2]</p>
<p>It would appear that a partial solution is to just scrap the style of the background and use one's own...</p>
<pre><code>style="?android:attr/textViewStyle"
android:background="@null"
android:textColor="@null"
</code></pre>
<p>Basically you get a clickable TextView that you can edit. But this doesn't strike me as the most elegant solution, so, I'm still hoping someone will chime in with my simply overlooking something obvious.</p>

188,983 | 188,984 | multiple preg_replace on the same variable | <p>While delving into some old code I've stumbled upon a function which is used to clean up special characters using <a href="http://de3.php.net/manual/en/function.preg-replace.php" rel="nofollow"><code>preg_replace</code></a> very excessively. Unfortunatly there's no way to avoid this cleanup, the messed up data arrive from outside.</p>
<pre><code>/* Example 1: current code */
$item = preg_replace('/' . chr(196) . '/',chr(142),$item);
$item = preg_replace('/' . chr(214) . '/',chr(153),$item);
$item = preg_replace('/' . chr(220) . '/',chr(154),$item);
</code></pre>
<p>Alot of those lines are in there, and all do the same (using different characters), so there should be a better way to do this. My first iteration to optimize this would be to use an indexed array, like this:</p>
<pre><code>/* Example 2: slightly optimized code */
$patterns = array();
$patterns[0] = '/'.chr(196).'/';
$patterns[1] = '/'.chr(214).'/';
$patterns[2] = '/'.chr(220).'/';
$reps = array();
$reps[0] = chr(142);
$reps[1] = chr(153);
$reps[2] = chr(154);
$item = preg_replace($patterns,$reps,$item);
</code></pre>
<p><em>It does the job</em>, but I guess there's somewhere a better and/or faster way of doing this alot easier and smarter - maybe even without preg_replace. Due to the early morning and/or the lack of good coffee, I was unable to find it myself so far.</p>
<p>Any suggestions?</p>

5,517,050 | 5,517,051 | Is String.replace implementation really efficient? | <p>I used to think that String.replace is faster than String.replaceAll because the latter uses Pattern regex and the former does not.

92,643 | 92,644 | fopen() error handling | <p>I'm working on a script at the moment that reads in an HTML template file, populates it with data and then saves the populated HTML file as a cached copy in my cache folder. </p>
<p>I'm having real difficulties evaluating whether an error has occured with fopen() whilst runtime errors are suppressed:</p>
<pre><code>$file = @fopen($location,"w+");
// manual states fopen() returns false on error
// though the below does not catch any errors
if (!$file) {
$this->doSomething();
}
</code></pre>
<p>Is the suppression working against me? I would really appreciate some insight into this. I have tried setting error_reporting to display no errors,</p>
<pre><code>ini_set('display_errors',0);
ini_set('log_errors',1);
error_reporting(E_ALL);
</code></pre>
<p>and removed the supression from fopen() but to no avail.</p>
<p>Thank you in advance!</p>

2,075,525 | 2,075,526 | How to migrate web.config? | <p><strong>situation</strong></p>
<p>We use migrations to update the database schema and configuration files for all deployments of our web application. Now we have a problem with migrating the web.config.</p>
<p><strong>current implementation</strong></p>
<p>The migration process does the following:</p>
<ol>
<li>Open the database connection</li>
<li>Read configuration from web.config into a configuration object</li>
<li>Retrieve all migrations</li>
<li>Iterate migrations
<ol>
<li>Update database schema (database connection is passed as parameter)</li>
<li>Update configuration object (configuration object is passed as parameter)</li>
</ol></li>
<li>Save configuration object</li>
<li>Close database connection</li>
</ol>
<p>Of course there is a lot of code that makes sure that the migrations are not screwing things up when something goes wrong. No worries there. Also restarting the webserver upon save the configuration is not a problem either.</p>
<p><strong>problem</strong></p>
<p>The problem is that it does not seem possible to make certain changes to the web.config through the configuration object. Like adding a location.</p>
<p><strong>possible solution</strong></p>
<p>My thoughts are now to not pass the configuration object, but the *.config files as a dictionary of xml documents. The migrations can then make changes to the raw xml. </p>
<p><strong>worries</strong></p>
<p>I am not too exited about this approach, because the configuration object does some configuration data integrity checks. This capability is lost when working with raw xml.</p>
<p><strong>question</strong></p>
<p>Is this the best approach?</p>

<p>Then I commented p1.destroy and instead of closing the browser from my Java program, I closed the window manually (File>Exit). In this case p1.exitValue started returning '0'.</p>
<p>My question is:</p>
<ol>
<li>Why program returns exit code as '1' in first case? Does JVM treats p1.destroy() as abnormal way of terminating a program? </li>
<li>In general the 'exit status code' value is JVM specific or Operating system specific? I have seen some question where people have reported exit code value as '10', '34545' etc..</li>

223,001 | 223,002 | Benefit of using static inner builder class | <p>During the course of writing the code guidelines for a company I found myself recommending using the <a href="http://stackoverflow.com/questions/5007355/builder-pattern-in-effective-java">Builder pattern</a> from Effective Java, instead of telescopic constructors.</p>
<p>However, after thinking about it a bit more, surely a more elegant solution is to just remove the builder class and the also remove the extra constructors with optional arguments. </p>
<p>So just have the one constructor with required parameters, normal getters/setters, and comment the code. When implementing just create a new instance of yr object then set values.</p>
<p>My original thinking was the benefit came from removing the confusion as to what paramters were optional and what were required; however the true benefit comes from using method chaining/fluent interface.</p>
<p>The builder pattern has benefits when you make lots of new instances as the ide can do the leg work and also if there are many (15+) optional parameters. However, is it worth the extra time coding the static inner class, would you recommend using the builder, or is it a waste of time ? </p>

The Excpet function works as long as the entries of the dictionary are of a simple data type. However, I'd like to store objects in the dictionay.</p>
<p>Here is my sample:</p>

{
Console.WriteLine(o.Key);
}
Console.WriteLine("Program finished. Press any key to continue");

</code></pre>
<p>Yet it only throws "ava.io.FileNotFoundException: /mnt/sdcard/unzipped/Eng_blue/altlayout.txt" which is the name of the first file and dies.</p>
<p>I thought that dirChecker() method would create this folders on the flow... any ideas how to fix that?</p>
<p>Thanks!</p>
