Microsoft Access Connection, Displaying and Updating Multiple Tables

I'm working on a senior project for a college class.  Instead of doing my senior project on something I knew, I chose to use something I've never done before (.net).  Basically I've chosen to do a simple order system using vb.net and access.  I'm looking for a simple way to display and update data from 3 tables in one datagrid  (actually, any object will do at this point).  Really, I'm completely lost on this, also I'm very new .net and only have limited experiance using vb6, so detailed instructions would be greatly appreciated.  I can send the solution file I have done so far if you'd like to see exactly what the hell it is i'm trying to do, just let me know at hanson_n@bellsouth.net.
