Does anyone have any VB.NET functions which validate an email address?
Could you post it? I would like it to do as much as the regular expression
validator if possible.
Thanks in advance!

there should already be a email validator regex function in the validators
to test for this (at least there is in asp.net) but here you go...
\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
regex function to validate all email addresses

Thanks, but I'm looking for a VB.NET version. Do you know of one?

Oh... I got it! Here's one I'd like to share. If anyone has any better one
please let me know.
Private Function EmailIsValid(ByVal strEmailAddress As String) As
Boolean
Return Regex.IsMatch(strEmailAddress,
"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9
\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$")
End Function
Thanks!

End Function
Unfortunately, this code will refuse mails from the "museum" domain.
Replace the {2,4} with {2,6} to allow for this domain as well.

In addition to the other comments:
MSDN has a handful of common Regular Expressions
patterns.
Here is the e-mail example: http://msdn.microsoft.com/library/de...mailformat.asp
The same section has a number of other examples.
I also find these pages to be useful when dealing with Regular Expressions: http://www.regular-expressions.info/ http://msdn.microsoft.com/library/de...geElements.asp
Hope this helps

I don't get anything of what is happening in the function!!! How does this
validate Email addresses and why not the museum domain??
Confused & (probably) stupid.
