Your instructor has no suggestions???? I think I'd look to take a class with another instructor!!

I'm betting that you're doing a DataSet.AcceptChanges() prior to the DataAdapter.Update(), whereas it should be the other way around. But if that's not it, post your code.

Other than the obvious (no changes persisting on the data source) the only indication that something's wrong is a test memvar that I've added. I trap the value returned from the Update() method and that value is zero.
