Q: VB Calculator: limit input 
I'm taking an intro to VB course at the UofArk. I was wondering
how you make it so that only numeric values can be typed into the text
box, and how I can put up an error msg when one tries to divide by zero. I
have set my variables as single, but text is still allowed to put into the
text box. Any help would be appreciated greatly.

A: Take a look at the example LimitImput. Concerning the error messaging use the vbcommand On Error Goto Return
