Hi, it's common to use a regular expression to test for valid email address:

Dim strMailAddress As String
Const pattern As String = "\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"

Dim rgRegEx As New System.Text.RegularExpressions.Regex(pattern,

 ' Valid
End If

Here are a more flexible test that does not use regex.
