RE: [INTERFACES] Visual Basic interface (Help needed)

ADO should be the most responsive of the lot (DAO, RDO, ADO) over a slow
connection.  However, you need to make sure that you are doing it right,
including making use of the batch updatable, disconnected recordsets that
ADO offers.  This capability means that a connection to the database does
not have to be maintained between getting the data, and updating it.  Of
course, if you select half a million records, it's still going to be slow.
But if your queries are optimised properly, and your update processes take
the disconnected recordsets into account, you can run quite well over slow
links.  Also, try to ensure that your ODBC is configured optimally, which
may be different for disconnected recordsets than for connected ones.
