   You can't take appropriate action on "true" control keys in the KeyPress   
   event; that requires the KeyUp or KeyDown event. And if you don't handle all   
   of the keystrokes that allow a user to Paste data (and the Mouse events that   
   allow it too), then your user will be able to Paste non-digits into the   
   TextBox. And, after all of that, I think you will still have missed one or   
   two places where the user can initiate a Paste operation.
