You can get the number of records from the RS itself. IMO, this isn't a good design and limits things in your application.

Actually, I think the COM should be working both in VB and VFP. But now it's seem VFP have some problem in accessing the COM in MTS.

Does the Fox component live in MTS? Does it have the proper rights to access the data?
