How to force ExitInstance() to be executed?

[s_k]

I have MFC application, in which I create one more CWinThread object, handled in separate thread, using AfxBeginThread. But when my whole app finishes, ExitInstance() of this user-interface thread is not executed. I need it to perform some cleanup..

Can somebody help me?

Thanks Standa.

I may be totally wrong but i think you need to PostMessage(WM_CLOSE) or (WM_QUIT) to the thread.

You're right, I've already found it out.
I was wrongly supposing that during termination of main process all children threads must be sent WM_QUIT message automatically...

I realize this is an old thread, but I have the same probem and I am sending the thread WM_QUIT.

The thread is a socket thread waiting for data and when the application closes, I send the thread the following message:

m_pNetWriteThread->PostThreadMessage(WM_QUIT, NULL, NULL);
::WaitForSingleObject(m_pNetWriteThread->m_hThread, INFINITE);

There is a breakpoint in the beginning of ExitInstance of the thread, and in debug, it never breaks there and it hangs up on the WaitForSingleObject.

Any suggestions?

Are you using blocking sockets? I assume since you are mentioning that you are waiting for data...so, the 'recv()' does block and thus your thread will ot process its message queue...
