Therefore I have extended the ListActivity class and added the following methods:</p>
<pre><code>protected void onListItemSelected(ListView parent, View v, int position, long id) {
}
private AdapterView.OnItemSelectedListener mOnSelectedListener = new AdapterView.OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View v, int position, long id) {
onListItemSelected((ListView)parent, v, position, id);
}
public void onNothingSelected(AdapterView<?> parent) {
// TODO Auto-generated method stub

};

<p>Now, when I create an instance of my new Class SelectableListActivity and override the onListItemSelected method, still nothing happens. Any Ideas? Many thanks in advance! </p>

<p>my code is this.</p>
<pre><code> class fileTypeFilter extends FilterIterator
{
public function __construct($path)
{
parent::__construct(new RecursiveDirectoryIterator($path));
}
public function accept()
{
$file = $this->getInnerIterator()->current();
return preg_match('/\.php/i', $file->getFilename());
}
}
$it = new RecursiveDirectoryIterator('./');
$it = new fileTypeFilter($it);
foreach ($it as $file)
{
echo $file;
}
</code></pre>
<p>my directory structure is something like this.</p>
<pre><code>-Dir1
--file1.php
--file2.php
-Dir2
--file1.php
</code></pre>
<p>etc etc</p>
<p>But as I said before the class is not recursively iterating over the entire directory structure and is only looking at the root. </p>
<p>Question is, how do use a basic RescursiveDirectoryIterator to display folders and then run the FilterIterator to only show the php files in those directorys?</p>

4,775,442 | 4,775,443 | How can I determine the "correct" number of steps in a questionnaire where branching is used? | <p>I have a potential maths / formula / algorithm question which I would like help on.</p>
<p>I've written a questionnaire application in ASP.Net that takes people through a series of pages. I've introduced conditional processing, or branching, so that some pages can be skipped dependent on an answer, e.g. if you're over a certain age, you will skip the page that has Teen Music Choice and go straight to the Golden Oldies page.</p>
<p>I wish to display how far along the questionnaire someone is (as a percentage). Let's say I have 10 pages to go through and my first answer takes me straight to page 9. Technically, I'm now 90% of the way through the questionnaire, but the user can think of themselves as being on page 2 of 3: the start page (with the branching question), page 9, then the end page (page 10).</p>
<p>How can I show that I'm on 66% and not 90% when I'm on page 9 of 10?</p>
<p>For further information, each Page can have a number of questions on that can have one or more conditions on them that will send the user to another page. By default, the next page will be the next one in the collection, but that can be over-ridden (e.g. entire sets of pages can be skipped).</p>
<p>Any thoughts? :-s</p>

<pre><code>Form2 frm = new Form2();
frm.QueryString = SQLstring();
frm.Show();
this.Hide();
</code></pre>
<p>It's OK to run form2 to show report, but when I try to export the report by clicking button 'Export report' on the left top corner, I got an error:</p>
<pre><code> static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());//Error occurred.
}
</code></pre>
<p>the error message is:</p>
<blockquote>
<p>"External component has thrown an exception."</p>
</blockquote>
<p>please help. </p>

5,629,238 | 5,629,239 | Upgrading to PHP 5.3 - solutions for legacy sites | <p>I am about to upgrade a couple of servers from PHP 5.1.6 to PHP 5.3.x, however, we host a number of old websites that would be time-consuming to fix in application code.</p>
<p>As I see it there are 2 solutions: </p>
<ul>
<li>stick the old sites on a separate, compatible server</li>
<li>make minimal (backwards-incompatible) fixes and turn off error reporting</li>
<li>fix all backwards-incompatible and deprecated features in application code</li>
</ul>
<p>The latter 2 options are not preferable given this would be very time-consuming -- bear in mind that there are no unit tests and such. The former will be at additional expense given we'd have to pay for and manage an additional box.</p>
<p>Are there any other options you might suggest trying, or <strong>what in your experience has been the best solution to managing legacy sites?</strong></p>

statement1.close();
Statement statement2 = connection.createStatement();
statement2.executeUpdate("...");

<p>If I understand correctly it shouldn't have any impact because all it really does is free the resources for the GC. <a href="http://db.apache.org/derby/manuals/develop/develop63.html" rel="nofollow">Especially with Derby</a>: You should explicitly close Statements, ResultSets, and Connections when you no longer need them.

<p>However will it cause any issues with the transaction? I don't believe the transaction relies on the Statement. Can anyone please confirm this?</p>

However, I'm developing an application that will need to pass some data to a website (id, name, points, etc.) and I don't want to show the response on the screen - I'll still want to record the response on a log file, I just don't want to show the page onscreen. Is there a class or method that allows this to be done? If not, is there a way to hide this component from the screen somehow? I tried to tag it as 'invisible' in main.xml but with no success.</p>

<p>Note: C is a template parameter</p>
<p>I know we cant delete a null pointer, an exception will be raised.
So in this case, the enum definition must be doing something to prevent that.

And this code is used in production, almost everywhere?</p>

46,830 | 46,831 | Way of overloading operator without changing original values? | <p>I'm wondering if you can overload an operator and use it without changing the object's original values.</p>
<p>Edited code example: </p>
<pre><code>class Rational{

5,107,802 | 5,107,803 | Inner classes defined inside a block like a method in Java can not have any modifiers not even public. Why? | <p>In Java, a class can <strong>never</strong> be qualified to be either private or protected. It can simply be <strong>public</strong> all the times. It's quite obvious, there is no question about it. </p>
<hr>
<p>Inner classes in Java however, can be designated with any of these modifiers private, protected or public. An inner class can also be defined within an individual block like a method. In such a case, an inner class can not be designated with any of these modifiers, private, public or protected.</p>
<hr>
<p>The following simple program is compiled with no errors and works just fine.</p>
<pre><code>package amazingjava;
final class Demo
{
public class Really
{
public class Quite
{
public class Surprising
{
@Override
public String toString()
{
return( "it really works !" );
}
}
}
}
}
final public class Main
{
public static void main(String[] args)
{
System.out.println( "It may be hard to believe, but " + new Demo().new
Really().new Quite().new Surprising().toString());
class Really
{
class Quite
{
class Surprising
{
@Override
public String toString()
{
return( "it really works !" );
}
}
}
}
System.out.println( "It may be hard to believe, but " + new Really().new
Quite().new Surprising().toString());

</code></pre>
<p>It produces the following output.</p>
<p><em>It may be hard to believe, but it really works !</em></p>
<p><em>It may be hard to believe, but it really works !</em></p>
<hr>
<p>Now, my question is only that the inner classes declared inside the main() method in the above example can not have any modifiers. An attempt to qualify those classes with any of modifiers private, protected or <strong>even public</strong> issues a compile time error! Why? Which default modifier is used by the compiler in such cases?</p>

2,754,598 | 2,754,599 | Android Custom Calendar for bookings | <p>I am busy writing an android app that needs to have a booking system. It needs to have a Calendar that users can view or navigate (Day | Month | Year) and click on to book events on certain days. Thus in the day view, you will see the booked events. These events will then be saved in the database under that users id.</p>
<p>The problem is to get a calendar view to do this without reinventing the calendar or programming a calendar from scratch. As far as I know, android does not have support for this or at least not for API 10. The app needs support from API 10 and upwards.</p>
<p>Also, I don't want to use the built in Google calender that comes with the phone or any calendar application running on the phone, because that places some restrictions such as, the device needs to have that app installed etc.</p>
<p>The screenshot shows more or less the view I am looking for. If I can get that type of view working with day , month and year views working, that will be great. Any help,resources, libraries etc. will be useful. </p>
<p>Please see the screenshot to see what I am more or less trying to do.</p>

<p>I had some code like this which worked fine almost everywhere but then I discovered it only worked about 80% of the time in FF 9.0.1. The fix was to do this:</p>
