Hello Michael Moriarity:
Thank you for your help! Your idea is better than mine.
I raised the previous question was just for getting idea from all of you.
In fact, after getting idea from you, my problem had been solved.
Thanks !!

Hello:
What I meant in my first post is that I think you are better off to forget
the whole idea of enabling and disabling the handlers, and just make
the handler smart enough to not do whatever it regularly does in cases
where you are merely placing database values into the text controls.
If you really think you need to do all this enabling and disabling of
event handlers, then I can't help you.On 10/1/05, Tang Tim Hei <timheit@netvigator.com> wrote:
