Hi There

I have spent alot of time trying to get a masked text box to validate
e-mails, but with no success. Mainly because I can't figure out how to
account for the wide variety of different e-mail addresses, for
example:
billwallis@hta.com
bill.wallis@hta.com
billwallis@hta.com.au
bill.wallis@hta.com.au

In the end I used a standard text box with a lenient regular expression
to validate it.

Is that the right appraoch or can I get e-mails working with Masked
Text Boxes?

TIA
Bill

Using a MaskedTextBox for email entry is not a good idea. This
component is at his best when it deals with hard-formatted
expressions, like a zipcode or a date.

Yes, you should use a TextBox (with an ErrorProvider component if you
like it). Here is a pretty good regex to validate emails :

"^[^@]+@([-\\w]+\\.)+[A-Za-z]{2,4}$"
