        new OleDbCommand("SELECT * FROM Categories ORDER BY CategoryID");
    adapter.SelectCommand.Connection =
        new OleDbConnection(connectionString);
    adapter.MissingMappingAction = MissingMappingAction.Error;
    adapter.MissingSchemaAction = MissingSchemaAction.Error;
' Assumes a valid connection string to an Access database.
Private Sub CreateOleDbDataAdapter(ByVal connectionString As String)
    Dim adapter As New OleDbDataAdapter()
    adapter.SelectCommand = _
       New OleDbCommand("SELECT * FROM Categories ORDER BY CategoryID")
    adapter.SelectCommand.Connection = New OleDbConnection _
