A just saw a program and the window was transparent. You could see your desktop through it, it was pretty cool. You could also adjust the transparency.
How can I do this. (win32 api, no MFC)
The program also said that it was for win2k or better. When I implement this function in my program is it possible to run the program on 98 or millennium, if I first test which OS is on it and use en if statement to bypass this function.
