The DBF file structure has zero credibility in the client/server world....period. DBF's and SQL/Server are worlds apart. To say that VFP has limitations forced on it to help SQL/Server Sales just does not make sense to me. If you wanted to direct your argument towards VB, then I would begin to see your point.

What kind of activity do you need to support? Have you tested VFP servers to see if they would fit the bill? Before dismissing them, you may want to test them in your scenario. ADO is based on the VFP engine and is the solution you are looking for. I don't see why you are put off by the fact that it is not bound in VFP. To me, this is a good thing since 1 data access strategy can exist accross the toolset.

Right, you have always been able to do this stuff. That said, I am not sure what your argument is???

I agree with these two reasons. Scaleablity is another factor.

Not sure about this. What does VFP have to do with the impossibility of pulling the plug out of a machine??
