I am also a vb.net forum newbie...but I might be able to give you a few pointers.

In the first example your entire structure needs to be above public class form1. Also, in the second example you probably need something like 'Dim a(20)(0) As Integer'. I can't guarentee this will help you, but I would say try those and report back if that helps or not.
