Re: user defined WM_ question: update

I imagine you still need some kind of listener for the "targeted event".
Your listener could then use PostMessage(WM_MYEVENT, 0, 0) to tell the UI
thread that the event has happened. You haven't provided any specific
information about the "targeted event", though -- for all I know, it's got a
specialized API to do exactly what you want.
