I agree 100%...I think RAD tools make great screen designers and get you into trouble if you take them beyond that. In fact, I would never even be looking at VB except I have to train a couple of VB jockeys from another company on how to access our system so they can make simple forms and run reports. My initial thought was to build views on the server encapsulating the more complex aspects of the database design for the vb guys to read and write from. I had hoped that it would be relatively easy to bind these views to various Microsoft stuff...and it is, but in a slightly more code intensive way than I had expected. I may try giving the ole db driver a shot and see if it provides better results. Merlin
