Hi, can anyone help me by showing me a sample of MS Access linked to Visual Basic that have edit, delete and add function?

Show us what you have so far. If you don't have anything then it's time to do some research. Use google to find some tutorials (there are several good ones) or get a book.

how about trying this first ?
there are a lot of tutorials regarding vb.net and access so it won't take you long to find a good start.. good luck

This is my favorite tutorial. And while you are looking for tutorials you should upgrade to Visual Studio 2012 Express, still free.
