DHorto #2 / 4	Validating/Validated questions That would handle the ESC key, but what about the Cancel button? Also, I would prefer this to be in one location, like in the class validating routines or something like that.

DHorto #3 / 4	Validating/Validated questions I have a class called cMyIntegerBox. It allows the setting of a minimum value and a maximum value. I also have a class cICLocnCode which inherits cMyIntegerBox and in the Sub New() it sets the minimum value to 1. cMyIntegerBox has a Private Sub to handle mybase.validating which checks to make sure a number was entered and that it is greater then the minimum value. Likewise, cICLocnCode has a Private Sub which verifies the location exists in the database. My problem is on a form I use the ESC key to exit the form (cancelbutton is set). If I am on a field tied to cICLocnCode and hit the ESC key, it does the validating for cMyIntegerBox and fails because the entered value is blank, which is less then 1. My question is I would like (I think) a way that if the ESC key is hit to NOT do any validating routines. Any ideas how to do this, or is there a better way to do what I am trying to do. TIA
