Hello, I am working with an MSSQL database, but I have a problem ( which previously, I've not encountered ).

Basically, whenever I try to update a row in my database, it works, but as soon as I restart the application, the changed information resets.

Example:

Code:
       Dim UN As String = DirectCast(Items(1), String)
                Dim R As LeafDataSet1.UsersRow = DB.Users.FindByUsername(UN)
                If Not R Is Nothing Then
                    R.Username = "Test"
                End If

                Users.Update(DB)
Items(1) is the username. R basically does a select statement, and then if R is found, it changes the username to 'Test'. This works, but when I restart my server and try the new username, it goes back to my previous username (I.E it doesn't work).

Any more information I'll be happy to provide. Thank you.
