Hi David,

Describing it as 'better' sounds like an opinion.


Mmmm, it may be so, but I'd like to clarify my opinion. Wink | ;-)
If the OP's problem was that he called ::WaitForSingleObject() with an invalid handle, it would return immediately with WAIT_FAILED, so this cannot be the problem. If the handle is still valid ::WaitForSingleObject() will either return zero or wait as expected.
Your suggestion to duplicate the handle is to circumvent the fact that CWinThread will close the handle in its destructor, unless the m_bAutoDelete member is set to FALSE. In this case my opinion of 'better' is to fix it the MFC way since it was introduced by MFC.
I think it's cleaner and hence 'better', but whether that's 'better' or not is a matter of opinion.

For what it's worth I think the OP has created some kind of race condition that may end up in a deadlock where the spawned thread sends a message to the main thread. In the message handler call chain he then waits for the thread to finished.....
