checking user input
i have a form with a few textboxes to be filled by the user.
After the user enter the first textbox, can i pop up a message box
to tell the user to enter string into the textbox if he entered numbers?
After the user enter the second textbox, can i pop up a message box
to tell the user to enter numbers into the textbox if he entered string?
if yes, can someone please give me a very simple code example based on it?
