[DUG] selective processing of Windows messages

[Ross Levis]

SendMessage is required because a result is usually required.  The 
messages are often used to return information to the 3rd party DLL in 
the wParam or Result parameters.

I've got it all working fine now with ProcessMessages.

Thanks,
Ross.

So maybe App2 should be using PostMessage rather than SendMessage?

Cheers,
