Phil,
I am not able to get out og message pump.
Here is the code
MSG msg;
iAllThreadDied = 0;
while (GetMessage(&msg, 0, 0, 0))
{
                DispatchMessage(&msg);
                if(iAllThreadDied ==32)
                        break;
}
::WaitForMultipleObjects (32,phThirtyTwoThreads,true,INFINITE);
Here all threads update global variable and still getmessage hangs
your suggestions please.
Amar.

No, that isn't true. Inbound method invocations to the MTA are completed
on threads from a pool that COM maintains.

In any case, COM threads should call CoWaitForMultipleHandles when they
need to wait. The CoWaitForMultipleHandles API checks the calling
thread's apartment type and either pumps a message loop (for an STA
thread) or calls WaitForMultipleObjects (for an MTA thread).

Is that true if the thread that put the object in the
table is a thread running in the mta?
