How do I get my Java application to shutdown nicely in windows?
I have a Java application which I want to shutdown 'nicely' when the user selects Start->Shutdown.

I've also tried using the exit handler on my main application UI window but it has no way to pause or ha...

Force application to shut down (.net)
Hi I'm looking to force my application to shut down, and return an Exit code. Had a look on MSDN and I can see that in WPF the Application has a Shutdown method which takes an error code as a parameter, but there doesn't appear to be one for System.Windows.Forms.Application. I can see Application.Exit() but not a way to pass back an e...
Ascertaining a shutdown is closing my application
Is it possible in .NET to ascertain whether my application is closing due to Windows being given a shutdown command (as opposed to any old application closing) in order to either write out some temporary cache files or even block the shutdown long enough to prompt for user input? Whilst my current scope involves a Winform app and a wind...
How do I get rid of Java child processes when my Java app exits/crashes?
I launch a child process in Java as follows: final String[] cmd = {"<childProcessName>"}; Process process = Runtime.getRuntime().exec(cmd); It now runs in the background. All good and fine. If my program now crashes (it is still in dev :-)) the child process still seems to hang around. How can I make it automatically end when the pa...

Since CServiceModule is available via _Module variable in all files I thought of something like this to cause CServiceModule::Run to stop pumping messages and shut itself down PostThreadMessage(_Module.d...

How to stop one of multiple WPF dispatcher?
I have an app with some background threads (actually an in-proc WCF-Service). Each thread runs its own Dispatcher to use some WPF-classes (MediaPlayer-objects to process some audio/video-files; it queues some delegates with BeginInvoke and finally call Dispatcher.Run). When the processing is done, I want to shutdown its dispatcher so tha...
Prompt user to save when closing app
I'm writing what boils down to a document editor. When the application is closing, I need to prompt the user to save changes. This is easy enough. My question is when is it appropriate to not prompt the user, and instead simply discard unsaved data and close. In the FormClosing event, the CloseReason enum includes: None WindowsShutDow...
Win32 API For Shutting Down Another Process Elegantly?
I'm looking for a way to shutdown a windows app from another. Is there a way to do this?

How to simulate windows shutdown while debugging?

How can I use the debugger to see what's going on? e.g. is there a way to send the windows shutdown message(s) to my application so it thinks windows is shutting down, so i can see exactly how it b...
Why does my application not close on logoff/shutdown (c#/.net winforms)?
My winforms app isn't shutting down nicely when I log off/shutdown. I have a main form, whose Closing event is fired correctly, but there must be something else keeping my application around. If I check Application.OpenForms there's just my one main form. The tricky bit, and where the problem probably lies, is that my application uses S...

How to get shutdown hook to execute on a process launched from Eclipse
Hi all. I have a shutdown hook in my application (created using Runtime.getRuntime().addShutdownHook). However if I launch the application from within Eclipse, when it is shut-down the shutdown hook doesn't execute. I think this is because Eclipse sends the equivalent of a force-kill signal to the process, which doesn't cause the shut...
