What would be the best way to check that text is a positive whole
number? I'm thinking about putting it in the textbox_exit event.
 
Hi

Exit is too late. Use the Keypress event. Set keyascii to 0 if its < 48 or
57.
Click to expand...

Except (tricky part coming up): Keydown event to trap and validate Ctrl V.

HTH. Best wishes Harald
 
You can validate the contents of the textbox using the isnumeric function.
You will also have to look for "-" and "." using the instr function.
