The VFP OLE DB provider does support Nulls. Would you use the VB "Nothing" or VFP NULL depends on what method you're planning to use to access VFP data.

That VFP app makes extensive use of whether a given value is .NULL. or not, so the VB app need to be cognizant of that. I'm going to be using the VfpOleDb driver to fill these tables, and what I ultimately need to know is whether the driver supports .NULL. and whether I would use the VB "Nothing" to fill a field with the value with the VFP equivalent of .NULL. If not "Nothing", then what?
