Jordon.....Also,
The funny thing about RECT is that I can define a rectangle in a window but when I want to draw in that rect, what do I do?
Do I simply draw within the rect area I specify( the real question here is how to specify that region?).
What about Regions? Can that help me or break me?
Thanks,
