exiting threaded program?

[Alex Hall]

Hi all,
I have a program with a timer in it, therefore I have multiple
threads. My method of exiting by using "user32.PostQuitMessage (0)" no
longer seems to be doing the job since I added the timer. What else do
I have to do to close my program? I say it is not closing because,
before, I would be returned to a prompt in the cmd line, but now I
cannot type in the cmd line window even after the program supposedly
closes, whereas before I could have. Thanks.

Is the "therefore..." an inference or independendent information?

If it is an inference then it may not be correct.

For example, timers in a GUI program need not involve additional threads.

My method of exiting by using "user32.PostQuitMessage (0)"

This sounds like the Windows API level accessed from Python, not Python level?

At the Windows API level, as I recall PostQuitMessage results in a WM_QUIT
posted to the current thread's message queue, where it'll be processed by this
thread's message loop, if it has one, which will then ideally finish.

Possibly, if you indeed have more than one thread, you're posting the WM_QUIT to
the wrong thread -- to quit the app it needs to be posted to the main thread.

Try to reduce the problem to a minimal complete program, and post that?

Unless the above comments help?
