COM message pump

Hello everyone,


Two questions about message pump in COM STA.

1. The term "message pump", means message queue? Pushing message into the message queue? Or retrieve message from the message queue?

2. What is the impact if the message pump is not alive in STA? It will block method invocation from other apartment?


thanks in advance,
George

It means the usual GetMessage, TranslateMessage, DispatchMessage loop to take messages out of the queue.

Yeah I'm pretty sure that's right. It might not be the only impact though.

Thanks iMalc,
