<p>Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.</p>
<p>Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off".</p>

<p>Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL.</p>

481,104 | 481,105 | Schedule a single-threaded repeating runnable in java, but skip the current run if previous run is not finished | <p>Sometimes the duration of a repeated task is longer than its period (In my case, this can happen for hours at a time). Think of a repeated task that takes 7 minutes to run and is scheduled to run every 10 minutes, but sometimes takes 15 minutes for each run for a few hours in a row.</p>
<p>The Timer and ScheduledThreadPoolExecutor classes both have a scheduleAtFixedRate method that is usually used for this type of functionality. However, both have the characteristic that they 'try to catch up when they fall behind'. In other words, if a Timer falls behind by a few executions, it builds up a queue of work that will be worked on continuously until it catches back up to the number of runs that would have happened if none of the tasks had taken longer than the specified period. I want to avoid this behavior by skipping the current execution if the previous run is not complete.</p>
<p>I have one solution that involves messing around with the afterExecution method of a pooled executor, recalculating a delay, and rescheduling the runnable with the new delay, but was wondering if there's a simpler way, or if this functionality already exists in a common library somewhere. I know about scheduling with a fixed delay rather than a fixed period, but this will not work for me since it's important to try to execute the tasks at their fixed times. Are there any simpler options than my afterExecution solution?</p>

895,402 | 895,403 | List view not rendered on postback | <p>I recently created a Usercontrol which contains a Listview (databound to a LinqDataSource) added the user control to an existing aspx page (loading the usercontrol dynamically).</p>
<p>I'm seeing an unexpected behavior where the usercontrol is being loaded and listview displayed when we initially load the page, but when I try to click the insert button (from the InsertTemplate of the ListView) the postback occurs, the page reloads but there is no sign of my Listview whatsoever, not even the headers, viewing page source confirms it is completetly gone</p>
<p>The problem is not that the usercontrol is not being reloaded, I can see other elements from the same usercontrol rendering ok.</p>
<p>I've gotten to the point where I've taken the usercontrol and loaded it into a new 'test' aspx page and it works fine there. I've slowly been adding items from my existing page to the test page (javascript,jquery validation,recaptcha, other asp.net controls) and it still works fine. None of the existing controls 'know' anything about the Listview so I can't see how it could be being affected.</p>
<p>Any suggestions as to why this might be happening or debugging options welcome. for now I'm just painstakingly recreating the old page into my testpage but it's time I could be much better using elsewhere.</p>
<p>Next step for me is moving a bunch of linked CascadingDropDowns over to the test page.</p>
<p>update:
I've noted another symptom on the postback, the 'ItemInserting' event of the listview is not being triggered.</p>

1,512,094 | 1,512,095 | Is there a way to test for enum value in a list of candidates? (Java) | <p>This is a simplified example. I have this enum declaration as follows:</p>
<pre><code>public enum ELogLevel {
None,
Debug,
Info,
Error
}
</code></pre>
<p>I have this code in another class:</p>
<pre><code>if ((CLog._logLevel == ELogLevel.Info) || (CLog._logLevel == ELogLevel.Debug) || (CLog._logLevel == ELogLevel.Error)) {
System.out.println(formatMessage(message));
}
</code></pre>
<p>My question is if there is a way to shorten the test. Ideally i would like somethign to the tune of (this is borrowed from Pascal/Delphi):</p>
<pre><code>if (CLog._logLevel in [ELogLevel.Info, ELogLevel.Debug, ELogLevel.Error])
</code></pre>
<p>Instead of the long list of comparisons. Is there such a thing in Java, or maybe a way to achieve it? I am using a trivial example, my intention is to find out if there is a pattern so I can do these types of tests with enum value lists of many more elements.</p>
<p><strong>EDIT:</strong> It looks like EnumSet is the closest thing to what I want. The Naïve way of implementing it is via something like:</p>
<pre><code>if (EnumSet.of(ELogLevel.Info, ELogLevel.Debug, ELogLevel.Error).contains(CLog._logLevel))
</code></pre>
<p>But under benchmarking, this performs two orders of magnitude slower than the long if/then statement, I guess because the EnumSet is being instantiated every time it runs. This is a problem only for code that runs very often, and even then it's a very minor problem, since over 100M iterations we are talking about 7ms vs 450ms on my box; a very minimal amount of time either way.</p>
<p>What I settled on for code that runs very often is to pre-instantiate the EnumSet in a static variable, and use that instance in the loop, which cuts down the runtime back down to a much more palatable 9ms over 100M iterations.</p>
<p>So it looks like we have a winner! Thanks guys for your quick replies. </p>

1,207,740 | 1,207,741 | Java: moving ball with angle? | <p>I have started to learn game physics and I am trying to move a ball with an angle. But it does not change its angle. Java coordinate system is a little different and I think my problem is there. Here is my code.</p>
<p>This is for calculating x and y speed:</p>
<pre><code> scale_X= Math.sin(angle);
scale_Y=Math.cos(angle);
velosity_X=(speed*scale_X);
velosity_Y=(speed*scale_Y);
</code></pre>
<p>This is for moving ball in run() function:</p>
<pre><code> ball.posX =ball.posX+(int)velosity_X;
ball.posY=ball.posY+(int)velosity_Y;
</code></pre>
<p>I used <code>(int)velosity_X</code> and <code>(int)velosity_Y</code> because in <code>ball</code> class I draw object </p>
<pre><code>g.drawOval(posX, posX, width, height);
</code></pre>
<p>and here <code>g.drawOval</code> requires <code>int</code>. I dont know if it is a problem or not. Also if I use angle 30 it goes +X and +Y but if I use angle 35 it goes -X and -Y. I did not figure out how to work coordinate system in Java.</p>
