Dear All,

I have some question and I hope someone knows the answer.

So, does each Private datasession share on VFP internal buffer?
I read somewhere, that VFP uses one file handle only, for the same dbf file. Is it true for different datasession, or each private datasession use a different file handle for the same table if I open it in each one?
It is important, because VFP only reads the latest table content when you open the table for first or when you flocks it. But flock scoped in per datasession, but REFRESH setting scoped generally.
I suspect, that opening a table first in a private datasession (while it is opened in an other private datasesion, too) doesnot count as really fist opening for VFP, so I have to flock-and-unlock it to be sure, it is the latest table content that I read.

Is it true?
