Exited Program Won't Die

[Laszlo Szijarto]

Thank you in advance for our help.

I have a program that, when the user exits out (X-closes the form), the
progam still appears to be running under Task Manager (Processes). I've
tried all kinds of things, making sure I set all my objects to null in the
form disposal method, etc. Nothing works. Is there something I can do to
make sure this program dies -- i.e., force it to kill off everything out
there?

Thank you,
Laszlo

You could use Application.Exit() or Application.ExitThread(), but these are
pretty severe.

I would first make sure that any spawned child threads or processes are
terminated properly. This is usually the most common cause for applications
not terminating.

Also, when you are setting your objects to null or disposing them, remember
to check that any custom objects that you have (that are implementing
IDisposible) do not have code in their Dispose() methods that might be
hanging the application up.

I would start tracing through your form's Dispose() method just to make sure
that everything is getting cleaned up properly.

If you could post your Dispose() method code, that would help too.

Thank you, I'll try all that. I tried to kill all threads, close all
FileStream objects, etc. I'm thinking that maybe some Interop components
I'm using aren't disappearing. For the time being, I'm running
process.Kill() for the current process, and that seems to wipe everything
out. I know it's severe, but I'm OK with that for now.

Thanks again,
Laszlo

Have you started any extra threads which could be preventing it from
stopping?

Hmmm, are you calling Marshal.ReleaseComObject on all your Interop
components immediately (or as soon as you can) after use? That could be the
key.
