Subject Re: [IBO] IB_Cursor
Author Artur Anjos
Hi Jason,

I use this method quite often. Just open IB_Cursor, get First, fill in
the combo box on a "while not eof" loop, and close IB_Cursor. If you're
data changes a lot, keep IB_cursor prepared.

IB_Cursor does not buffer datasets, so you just use one row at the time,
and you can't jump to prior record (that's the difference - ib_cursor is
unidireccional and non-buffered - that makes it faster than a TIB_Query)
