Good


Still something that bugs me
Do you need Tables here as a property ? - since tablesTmp is stored in oApp.Tables

       ' Data dictionary
        Public Tables As New Tables
        ' don't need this - Public TablesTemp 

        ' Load the data dictionary
        Public Function LoadDataDictionary() As Boolean

          dim tablesTmp as new Tables
                    
          'the framework is still using Tables

          ' populate tablesTmp if needed

           oApp.Tables = tablesTmp ' from now on the newer version will be used

                ' Let the framework know that we are done
            ' This will only happen at startup as there is no need to turn this off on reload
            App.lTables = True

            Return True
        End Function
