FLIP: Demonstrates BitBlt and StretchBlt Animation FLIP is a Visual Basic(TM) program that uses the BitBlt and StretchBlt functions to animate graphics. The program simulates flipping tiles. BitBlt copies icons instead of using individual picture boxes. StretchBlt also copies bitmaps from a source to a destination, but compresses or stretches the original bitmap. To load FLIP files in the Visual Basic environment, run VB.EXE, choose Open Project from the File menu, and select the FLIP.MAK file.
