Class TSelfRefreshQuery (unit RefreshQ) |
TQuery
Version 2.33 Aug-23-1997 (C) 1997 Christoph R. Kirchner TSelfRefreshQuery is a TQuery-descendant that uses BDE-Callbacks to refresh itself if the dataset got modified by another program or by another TDataset-component in the same application. Delphi 1: Queries on Paradox tables only. Delphi >= 2.0: Queries on Paradox and dBase tables, queries on Interbase tables get the refresh-event only inside the application, others not tested yet. Please Note that querys cannot get refreshed if RequestLive is false. The author assumes no liability for damages and disclaims all warranties. See disclaimer in Readme.txt.
