Magnetic Form in Visual Basic

This program will "stick" this window to another application. It will stay on the left of the other app, and it will match its height. If the other app moves too far to the left for this window to fit, it will stick to the right side. If the other app maximizes, this one will revert to it's original size and float on top. If the other app minimizes, so will this one. Note that floating on top will work ONLY when this program is compiled and run as an EXE.
