Hi all,

I have a windows forms app that populates 3 tables from an xml feed. It is all working great (thanks Jim for the great tutorials!) but I only have one niggling problem.

On the first load of the xml into the the database, I can see the data loading into the Access db by opening the accdb file. However, changes made to the data in a DGV control DO NOT get saved in the back end db the first time the db is loaded. If I close down the app after loading the data, then make changes everything works as it should and changes are saved.

Seems I am missing an important step some where...here is the code I am using to fill the tables:
