It makes me recall some C# threading stuff, but more related to COM
STA model. I think "Join keeps message pumping alive while blocked;
Sleep suspends message pumping", I think means Join is better than
sleep since during join a thread's message window could still accept
message from other apartment, but if a thread is sleep, all the
messages to the window will be blocked. It means sleep will block
operations from other apartment, right?
No idea. I know next to nothing about C# or .NET. Consider asking in
microsoft.public.dotnet.framework.interop
You are just responsible for retrieving the message with GetMessage,
and delivering it to its target window with DispatchMessage - just
as you do with any other window message. The window procedure of
that hidden COM window will take care of invoking the right method
on the right object. That's the whole point of that window's
existence.
Sorry it is new to me. I want to confirm with you that, COM runtime is
responsible for creating the window, and I am responsible for
retrieving message from message queue, process it, and return message
into the queue, right?
You are responsible for calling GetMessage and DispatchMessage. That's
it. How many times do I need to repeat this?

necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
