Alphablended (Transparent) Windows

This code will demonstrate how to create a window with partial transparency. The color of the window and the amount of transparency (in percent, from 0 to 100% transparent) are customizable. The code involves no screen capturing, it is actually an alphablended window. The window contents update in realtime as the window is moved, sized, or manipulated in any way. This only works in Windows 2000/XP.
