Re: Clean-up in OnDestroy

Hi Joseph,

If a thread is blocked on a semaphore what do you offer to do to terminate
that thread other than releasing the semaphore?

Suppose a thread proc like this :

while (bContinue)
{
        if (WAIT_OBJECT_0 == WaitForSingleObject (hSemaphore, INFINITE))
        {
                // Land the spaceship...
        }
        else
        {
                // I always wonder what other programmers do here...
                // My choice is landing the spaceship :)
        }
}

If this thread blocked on the semaphore then we set bContinue to false and
relese the semaphore to terminate the thread gracefully :

bContinue = false;
ReleaseSemaphore (hSemaphore, ...);

Am I right now?

In respect of waiting threads to terminate :

I always think that terminating a process before it's all threads terminated
is a bad practice. So I initiate terminations for threads and wait them to
terminate. It sometimes gives useful information about idden bugs related to
thread termination. Off course, your warning about dead-lock should be noted
and threads should be leave alone with their terminations if requred to do
so.

And eventually, I should think about ActiveX related cases a bit more
considering your warning.
