Using entries from a textbox to update a simple access table

I familiar with how to populate information from an access table to textboxes but not the other way around. I am familiar with the DataTable class.

I would appreciate any methods whatsoever on how to do this with as much detail as possible since I am not an expert on database connections.

Follow the Database FAQ link in my signature and check out the .NET resources there. You might also like to follow the Data Walkthroughs link.
