This can be the usual problem that you need to process windows events (so that COM events work) when you are running in a single-threaded appartment which is the default. You must run a messageloop otherwise COM events are not delivered. If you have pywin32 installed, this should work: ... connection = ShowEvents(myobj) import pythoncom; pythoncom.PumpMessages() comtypes 0.4.0 contains even better code that you can also use, it is carefully hidden ;-) in a test case: ... connection = ShowEvents(myobj) from comtypes.test.test_showevents import pump_messages pump_messages(10000) The pump_messages function takes an integer which specifies the timeout for this function, in milliseconds. The advantage of this function against pythoncom.PumpMessages() is that you can interrupt the message loop with pressing CTRL+C, and that it has the timeout parameter. Thomas PS: I think the comtypes.client module should expose this function, it will be named PumpEvents(), and it will take the timeout parameter in (possibly frational) seconds. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
