Hi Randor,

99% of cases the thread is already terminated, when the WaitForSingleObject() is called.

GetExitCodeThread() also uses CWinThread object handle.
I presume if the thread is terminated and the examination of the property m_SomeThread->m_hThread leads to some hanging in my case.

The thread simply do some math calculations as the user click the button, then prints the results of calculations to the GUI by means of PostMessage. The result is in the message params and GUI MFC juts put that result into the main dialog window.

So the user click the button, thread do some clever math in about 1-2 seconds, then the results are sent by PostMessage.

I did not want to go into disabling that button, while the thread is not finished, so I tried to use WaitForSingleObject() to make sure the thread will not be called twice if user clicks the button, before the thread terminated

Many thanks.
