RE: TZF - not only a Topaz Problem

Pierre:

You might want to check out this article on Borland's website about controlling key entry:

http://bdn.borland.com/article/0,1410,28452,00.html 

You can get creative with the ideas they present and ensure that the user enters only negative numbers or only enters positive numbers. I don't know about mixing it with a mask. Maybe on entry set the mask to nothing and then reset the mask on exit. Something will get it to work though. And, that is why we are programmers right? Have an idea and make it work.	

Hope this was helpful.
