Validating User Input (numeric only, and valid email address attributes)

[charleswesley]

I find myself regularly needing to validate user input as either a)
numeric only or b) valid email address format ([email protected])

I am assuming that there are regular expressions that can be used to do
this as it doesn't appear that 1.1 includes this functionality itself.

I am interested to know if anyone has a simple vb.net example of a
solution to either of these issues. I'm new to regular expressions but
if I have a working example I am sure I can move forward from there

thanks

Hi,
You can use RegularExpressionValidator controls to validate user input
against regular expressions.

Check out www.regexlib.com for specific regular expressions (including for
email addresses).
