How do you validate an entry in the texbox? (visual basic.net)

[Guest]

Hi all,

I have 2 textboxes in my windows form. If the user types in a negative value
in one textbox, the user must definitely type in a postive value in the other
textbox.

How am i do enforce this?

Thanks

Helpless,

You can use the validating event from both textboxes.

Be sure that you check as well for a zero situation otherwise it will
probably never end.

I hope this helps?
