I stumbled upon a couple of Visual Basic apps that I wrote just after I started programming in 2001:

I was learning VB at college and fiddling around with windows API stuff.

The first application demonstrates window enumeration and lets you manipulate all of the windows that are currently loaded.

The second application was supposed to be a utility that allowed you to add commonly used applications to a list which could be accessed via the systray. There's a bad bug in it which means it crashes when it first runs!

Happy to say I've learned from my mistakes 6 years on :)
