I am new to VB and currently writing a small program with a number of text boxes. As a number is entered in a text box I need to evaluate it and decide if it is within limits. If the number meets the conditions the user will move on to the next text box, if the number is out of bounds the focus must stay with the text box for a revised value. I've tried a number of possibilities, but nothing I've done seems to work. Any help... or hints would be appreciated. Thanks.
