On the VB team blog site ([url:http://blogs.msdn.com/vbteam), I wrote a four part series in which I walked the using through building an application to create Paint-by-numbers puzzle. (If you don't know, Paint-by-numbers is a popular puzzle where you try to create a picture from numeric clues.) In the series, readers will learn how to implement owner draw, implement undo/redo, load and save files, and print. The blog series can be found at:

The attached file contains the source code for this. It was built using VS2005 but the code should work for all .NET versions of Visual Studio.
