These functions use less memory and fewer resources than individual picture box controls to display and move the different pieces of the puzzle around the window.

Region functions create, alter, and retrieve information about regions that can be filled with graphical output. You can use region functions with clipping functions to create clipping regions. A clipping region is a portion of a window where GDI creates output. If you send output to an area of a window outside a clipping region, the output will not be visible. Bitmap functions display bitmaps; these functions let you prepare images in memory and then copy the images to the display.

To load Jigsaw files in the Visual Basic environment, run Vb.exe, choose Open Project from the File menu, and select the Jigsaw.mak file. You can also make an executable file and run it as a separate program using the Visual Basic run-time file, Vbrun200.dll.

Jigsaw was built with Microsoft Visual Basic version 3.0 and tested under Microsoft Windows version 3.1.
