Interesting… that is a nice debugging tip…

Anyway… I placed statements before and after each adapter update. Both have the “dataAdapter.AcceptChangesDuringUpdate= False” statement.

Code:
        If dt.GetChanges() Is Nothing Then
            MessageBox.Show("Before Red UPdate-There are no changes to save.")
        Else
            MessageBox.Show("Before Red UPdate The are changes to be saved.")
        End If
Results:

Before and after both adapter updates, the message indicated that there are changes to be saved, however, the second adapter did not update the database table. I reversed the order of the adapter updates with the same result. The first adapter updated the database and the second did not.
