Thanks for saving me the time I would have spent diving into this. It sure would be nice if VFP 7.0 allowed container objects to have their own datasession. VFP would be a much more flexible and independent object development environment if datasessions were available at the business element level. My frameworks would benefit greatly.

Thanks,
