Kevin in the actual case of this error the following was done:

I opened the Northwind example and made the minimal changes shown in the help file

ie:

added reference to vistadb

changed the business object to select between vistadb or sql server
added a connection string to vistadb

I then used the vistadb migration utility to create a vistadb database from the northwind sql server database

I then added a connection string to the app.config file that would call the vistadb connection

I compiled

ran the app

selected the lists option and chose employees

the employees showed up implying that the database was being read

I chose to add a record

upon completeing this I save and get the error

With regard to my actual code the error is same I agree I should use the createempty dataset call (corrrect form - all constructor code called) but I am not even refering to this code

THE ERROR IS FROM THE NORTHWIND SAMPLE IN MERE MORTALS

IF I DID SOMETHING WRONG THAT IS FINE (WHAT IS IT????)


I would be happy to send you the project BUT I really only did what I said!!

If I had to guess it is in the vistadb adapter!!

Cheers,
