>>>I have a textbox on a form, bound to a data field. I want to know, when the user exits the field, whether or not they changed the value of the textbox. I want to compare the new value to the previous value, NOT to the value of the field in the table, because the user may change the textbox several times while still in the screen.

Sure, you could do that. My instinctive reaction, however, is to go directly to the method that handles the changes. InteractiveChange doesn't fire with every keystroke, BTW. It discards the enter and tab keys, but I understand what you're getting at. Additionally, you look at the value of GETFLDSTATE(JUSTEXT(This.ControlSource)) or OLDVAL(). It is dependent on the situation, however, and these may not be approrpriate in all cases.
