Hi Kevin

Thank you for your answer and your detailed instruction.
I was engaged in an other project, so it was not possible for me to answer earlier.
However, your answer was OK and I was able to begin with the task of migrating the MM.NET/MSDE_SQL application to MM:NET/VistaDB. That was really a big task, because I use all features (Localization and Security etc.). I had to find a solution every time the business object is used. Fortunately, your really good design with the factory methods and the managers made it possible. Now almost everything works fine with some exceptions:

- It seems to be a problem to grab the PrimaryKeyValue between a NewRow() (with an Identity-Field) and a Save(). (I use it for another method) In the MSDE/SQL it was possible to take the value from the TextBox but in VistaDB it is there only after the Save().

- Further, there is also a problem with the Primary Key in der Mover Dialog. There, you copy the lists to a TempTable. With VistaDB the PrimaryKey-Definition goes lost. Up to now, I didn't find a solution for that (without changeing the framework).

Many thanks in advance if you can answer again. By the way, I am a convinced user of your MM.NET framework.

Regards

Ernst
