Dear critics,

You are very friendly in your critic, but a multi-user work may be different. Even with Optimistic Buffering we can add records by one record with immediate updating and then edit whole table buffer. Such approach also has the right to live.

I have used the Cetin's advice and have prepared the test application for discussing routines. If you are interested in it you can download this application from http://www.geocities.com/vhpcg/download/test_pk.zip.

Best regards,
Vladimir Trukhin
