My code resides in a dll. Here, I create a new thread where I instantiate a prof-uis based dialog class, with a bunch of controls. One of the controls is a popup menu button. When I open the menu associated with this button and press the Insert or Delete key, I get an assert/crash in the prof-uis code. I traced this to these lines in extpopupmenuwnd.cpp line 17559:

HKL hKeyboardLayout =
::GetKeyboardLayout(
( ::AfxGetThread() ) -> m_nThreadID
);

Basically, m_nThreadID is 0, I’m assuming since it’s trying to get the id of the main thread, while running in a different thead.

I get similar crashes in other cases, but they all seem to be cause by this threading issue.

Any idea how to fix this?

Thanks,

Adrian

It turns out that I was starting the thread using beginThreadEx when I should have used AfxBeginThread. I changed the code accordingly and that fixed the crash.
