Thanks for responding Sean. I am doing an intranet application wherein users would be required to fill in forms that would be saved in a MS SQL table/database. What I would like to do is to be able to limit the users from entering alphabetic characters in a textbox, they must only enter numeric characters. It's like programming in foxpro where you can format the entry with "XXXX" or "9999" for alphabetic or numeric. That's what I would like to do only in this case, via the net browser. Can you help? Thanks again!
