Window Transparency

Is it possible to use the user32.dll lib and this command:

api_SetWindowRgn% (hWnd%, hRgn%, bRedraw%) : "SetWindowRgn"

to make a transparent window? If so, could you tell me the parameters, and possibly give me a code sample?

OK. I'm making progress. I think another way to do it is to make a layered window. There are some things that have to do with layered windows here

any ideas? It's driving me nuts.

I figured it out. For anyone that's interested:
