Thanks very much, Michael. Your help is far over what I expect. Using the converter program is a better than looking up the near 100 pages long table. Is some sort of internal structure how the table is formed?
The last time I used a Chinese word processor was more than a decade ago. I may need to figure out how to enter Chinese characters with a regular keyboard. I remember there are quick few entry methods. Server side validation error messages come from the server, not on the presentation layer. It is better to be localizated as well as. 5/24/2002 12:56:46 AM, "Michale Zhou" <[EMAIL PROTECTED]> wrote: >Vernon, > >Your last question first.
