Visual C++ Language
I have a user-interface thread that creates a dialog box:
BOOL tcMyThreadClass::InitInstance()
{
mCMyDialog = new tcMyDialog;
m_pMainWnd = mCMyDialog;
.....
return TRUE;
}
I want to terminate this thread (call its ExitInstance()) whenever mCMyDialog::OnCancel() is called. But I can not get mCMyDialog to post the WM_QUIT message to this thread. It will only post it to the main thread that created this thread. What am I missing
Well, it's hard to tell without seeing the code. You should post it here.
Does the dialog have a pointer to the thread
I figured out a way around the problem. The thread no longer needs the WM_QUIT message.
thanks
The CWinThread::ExitInstance documentation clearly states not to call it. Perhaps you mean that you want to cause it to be called. Since it is a UI thread you probably don't want to post a WM_QUIT message either.
The typical solution is (for the main thread) to create an event that the thread waits for to signal it to exit.
