• Why is my BeginInvoke method not async?

  - by Petr

  Hi, In order to avoid freezing of GUI, I wanted to run method connecting to DB asynchronously. Therefore I have written this: DelegatLoginu dl = ConnectDB; IAsyncResult ar=dl.BeginInvoke(null, null); bool result = (bool)dl.EndInvoke(ar); But it is still freezing and I do not understand why - I though BeginInvoke assures that method it references is run in another thread. Thank you!

• background worker in asp.net

  - by vbNewbie

  I migrate my winforms crawler app to a asp.net web app and would like to know how to implement the background worker thread that I use for very long searches? Another posting mentioned asynchronous pages but I am not sure if this would work or how to apply it. The search function that would run can sometimes run for a few days and I would like the user to have the option to perform other functions still. Can this happen?

  I have a file in a folder like this: installer-x86_64-XXX.XX-diagnostic.run The XXX.XX is a version number and I need the version number only. How to do it in linux? I have this code: #!/bin/bash current_ver=$(find /mnt/builds/current -name '*.run'|awk -F/ '{print $NF}') So this gives me just the name of the file correctly (minus the location, which I dont want). But how do I only get the XXX.XX version number into a variable such as $version

• JUnit : Is there a way to skip a test belonging to a Test class's parent?

  - by Jon

  I have two classes: public abstract class AbstractFoobar { ... } and public class ConcreteFoobar extends AbstractFoobar { ... } I have corresponding test classes for these two classes: public class AbstractFoobarTest { ... } and public class ConcreteFoobarTest extends AbstractFoobarTest { ... } When I run ConcreteFoobarTest (in JUnit), the annotated @Test methods in AbstractFoobarTest get run along with those declared directly on ConcreteFoobarTest because they are inherited. Is there anyway to skip them?

• Adding images to a JAR file in Eclipse?

  - by ChrisFreeley

  I'm trying to make a game in java, but I'm a bit of a newb. The game has images, and when I run the application from eclipse, they all show up fine. But when I export the project as an application, the images don't show up. When I put the application in the same folder as the images, they show up when I run the application, so someone suggested that I just need to put the image files inside my JAR. Can someone tell me how? Thank you

• Python: Streaming Input with Subprocesses

  - by beary605

  Since input and raw_input() stop the program from running anymore, I want to use a subprocess to run this program... while True: print raw_input() and get its output. This is what I have as my reading program: import subprocess process = subprocess.Popen('python subinput.py', stdout=subprocess.PIPE, stderr=subprocess.PIPE) while True: output=process.stdout.read(12) if output=='' and process.poll()!=None: break if output!='': sys.stdout.write(output) sys.stdout.flush() When I run this, the subprocess exits almost as fast as it started. How can I fix this?

• Why does Microsoft tie .NET runtime versions to specific versions of VIsual Studio?

  - by Armentage

  Why is it that I have to upgrade to VS 2010 to build/run .NET4 projects? This seems somewhat ridiculous to me. Why should the run-time that my code runs against, or the compiler that the IDE invokes (hopefully) generically through MSBUILD rules have anything to do with the IDE I am using?

• How can I prevent javascript errors in my selenium tests from hanging my build system?

  - by lowellk

  We are having a problem with our selenium tests which run in IE on a virtual machine. Whenever there is a javascript error, a popup shows up and puts our system into a 'stuck' state - a user has to go clear that and restart the selenium test run. Is there a way to prevent the javascript error popup from putting the system into its stuck state? Would setting window.error be of any help here?
