That's a very old page, very empty... Time for a little brush up.
I will begin with one VB tip (the very old one...), handling a delicate case among beginners:
How to get back strings from C and C++ API calls
and I add a more generic tip for all languages (more a Windows trick than a programming one, but useful for programmers of course):
How to create file associations for your programs, using the registry
I made a page on Processing.
I have put a link in the main page, but I recall here I have made a tutorial page on Regular Expressions.
