Hi,

I have a form that collects inputs from the user and verifies it against a
set of criteria.

As it stands at the moment, the code that does the evaluation is triggered
by the TextBox Exit event (when the user presses the enter key, tabs or
simply clicks elsewhere). This also causes the cursor to move on to the next
box in the tab index list.

How do I interrupt the tab index list in the event of an error (or point the
code back at the textBox in question) so that if the user inputs an invalid
value, the cursor remains in that TextBox?

TIA

Dave
