Hello I am woking on a log on program in Access and Having trouble with the interface to add new users. I use a list box to show them and a seperate From to add new users. Now it work fine, but when I add a user that has a charichter in it, come of them blow it up quite nicley, such as ' " , ; | \ ! all either throw off my index on the Listbox, or group all the records together thinking there the same. I would use Input masks but (beside the fact that there ugly) I need some of the chars in there such a ^ and ~ (which don't explode the program). what I need is some form of Is letter fucntion, but can't find such a thing to exisist in Access. If anyone knew of such a function that would be grand.
