There are a couple of routes you can take to communicate with MS Access in LabVIEW. The preferred method is our Database Connectivity Toolset. This allows you to use VIs to communicate with your database. Here is a link to the product for more information.

Your other choice would be to use ActiveX. I believe there are a couple of examples on our web site using it. Overall you will probably spend a lot more time taking this route.
