Code Snippets

Here you’ll find free code written with either Visual Basic 6, ANSI C or Java. Feel free to use the code in your programs with or without acknowledgement. It’d be nice if you could let me know if you find something particularly useful, especially if you do use it in another program.

If you have any problems with any of the code below please contact me and I’ll try to help, time allowing.

Code written in ANSI C.

• SVGAlib colour swatches - A program to display swatches of the 16 standard colours SVGAlib uses.
