Don't forget "0", you might need it.  ;-)

There are many ways to do this.  For example:

1) One very simple way is to monitor the KeyPress event for the text box 
in
question and raise an error if the key pressed is not the ASCII 
equivalent of
1 through 9.

2) You could also to this in the Validate event of that text box, where 
you
examine each character for validity.

and so on.

How do you allow the user to only enter the numbers 1-9 as valid values 
in a
text box in Visual Basic
