Since you are using Access as the back end, you will need the following namespace added to your form by inserting the following:
Imports System.Data.OleDb
Next, read up on the use of the following data objects and properties:
1.) OleDbCommand
2.) OleDbDataAdapter
3.) Dataset
4.) DataGridView.DataSource
Your post is very general in nature. If you are trying this for the first time you will generate many more questions before you are done.
Good luck.
