Simple MIDI keyboard events

I have the following problem:

I have a MIDI keyboard (basic thing, no extra controls, just a pad with keys with a cable sticking out). It works fine in for example Anvil Studio, so it's communicating fine.

What I want to do is write a VB.NET program in which an event is raised when a key is pressed, so that I can control things with the MIDI keyboard.

If there's anybody out there who could help me to something that does this (a library or control or something would be beautiful). I've searched the net for hours to no avail - only VB5/6 examples. Thanks in advance!
