ok, try like below,

1. In Mouse Down Event ,

copy the original value to a variable from textbox.


2. In Mouse Up Event ,

check your value in textbox, if it is incorrect, replace the old value from the variable to textbox.


<X>

The Validate event might be of some help. It allows you to prevent the user leaving the control until you're ready (as long as the .CausesValidation property is True).

This is all assuming we're talking about VB6. If it's VB.Net then forget I said anything.
