sorry, i do not want to be rude, but the problem you are, it is not asp.net, at first! you have to understand what means 'inheritance', 'class', 'codebehind', and many 'things'.
this book:
Beginning ASP.NET 1.1 with
VB.NET 2003
by Chris Ullman, John Kauffman, Chris Hart, David Sussman
December 2003
will give you a very very good explanation about you need.
