I think you'll find that SendMessage/PostMessage will only work if the
component owns a window handle - after all, that's how they figure out
where the message is going.
If you're writing the component then you can create an invisible window
to act as your message target. There's a good example of this method
in the ICS TWSocket implementation... which is a nice crossover to the
TCP/IP thread here :>
(If you don't want to mess around in the ICS source, let me know and
I'll post the relevant part)
