The transparent form effect is done with Regions.

First create a region that encompasses the entire form.

Then, find the client area of the form (Client vs. non-Client) and

combine with the full region with RGN_DIFF to make the borders

and title bar visible. Then create a region for each of the

controls and combine them with the original (FullRgn) region.-The transparent form effect is done with Regions.
