Ok know after a serious work on MS Resources I'm getting better
understanding of what is ADO and what Borland wrapped, but I may still say
that this ADO wrapper is not as Borland useto wrap in other areas:) Thanks
to TBetterADO...

Anyway since I have direct access to pure ADO I am a full powered ADO user
as much as a VB user.

Thank you...
