Simon,

There's a bit more to it...you need to subclass the mmDataAccessBase abstract class and create a new concrete DataAccessVistaDB class. You then need to implement the abstract methods with code that is specific to VistaDB. Afterwards, you need to override your ABusinessObject's CreateDataAccessClass() method so it knows to instantiate your new custom data access class.
