Re: message pump code for COM STA

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi George,

My question is not how CreateWindow/RegisterClass/WNDPROC works, but
who is responsible to write WNDPROC and register it in the case of
STA message pump for the handler for the hidden window? The question
is which party does this. I think COM Runtime does this during
CoInitialize(), right?

Yes.

Why do you ask the same questions over and over again. Igor answered this
question in "C++ COM STA model" on 24th of march. See below.

In COM STA model, a hidden Window will be created with synchronized
message pump operation.

Not quite. COM will create a hidden window. Your thread is responsible
for pumping messages to it (except in certain situations where COM
enters a modal message pump, e.g. when you make an out-of-apartment COM
call).

1. Who (which party) is responsible for generating code to create the
hidden Window

COM creates a hidden window in CoInitialize. I'm not sure what you mean
by "generating code".
