    ADO async or sync


    I have a very large database application where the
    tables have 4-500,000 records we need to search on various
    fields that would not form a qood index, plus a search using
    ranges is needed.

    I would like to find the first record have the system continue
    looking for data and as data is found fire a routine in the app
    to let the app know that more data is available to load into
    a grid.

    Any ideas??

    Thanks

    I have a sample at http://www.concresco.com/grids.htm which uses
    asynchronous fetching. See if that helps.
