Hi, I understand this is your first post but you should post this in the correct forum. There's one for VB already.

I would also like to point out that people don't like to solve homework unless they see some effort. It's better that you refer to some book, if you want to start learning VB .NET or visit MSDN website. If you are looking for ideas of going about your problem, a good way is to post some of your ideas and see what others have to say.
Best of luck with your assignment.
