Click to See Complete Forum and Search --> : COM client message filter problem


April 19th, 1999, 03:23 AM
I have a COM client program. On MFC mainframe, there is a menu command which makes a long COM call (20 seconds to complete), while there is a OnTimer()
which makes another COM call every 1 second.
I always encounter a RPC_E_CANTCALLOUT_INEXTERNAL error when menu command is
executed. How to avoid this COM message filter problem?
