One other thought. Create a subclass of your textbox and put the code in the VALID of that subclass. Then hack the SCX and replace the Class field with the name of that subclassed textbox for Class = 'current_textbox_name'

I need to know if the user keyed through the text box controls at all. Can .setall be used for this? How to do it ?
