I know this is a really old message, but I was having the same problem today in a VFP 8 app and found your problem and consequently the pre-VFP9 solution to my problem. (I can not use VFP9 on this app yet.) Anyway, the good news is you can now SELECT against buffered data in VFP 9 --

SELECT ... FROM ... WITH (BUFFERING = .T.) WHERE ...
