The MaskedBox is a piece of ... (something that is not cake!!!). I never use it. I always use regular textboxes (with a lot of validation) if I can't use 3rd parties.

149$ US = 225$ CDN. You cost more than this each day you work (and you can't get a control like this in 1 day of work). So why spend time re-inventing the wheel!
