Dim Rep, Pmail: ChkMail = True: Set Rep = New RegExp
Rep. pattern = "([. a-zA-Z0-9 _-]) {} @ ([a-zA-Z0-9 }(. ([a-zA-Z0-9]) {2,}) {} $"

Dim regEx, Match
Set regEx = New RegExp
RegEx. pattern = "^ w + (-w +) | (. w +) * @ [A-Za-z0-9] + ((. |-) [A-Za-z0-9] + )*. [A-Za-z0-9] + $"
RegEx. IgnoreCase = True
Set Match = regEx. Execute (strng)
If match. count then isemail = true

Method 3

 

Public Function IsEmail (ByVal PString)
Dim Plt, Pgt: Plt = False: Pgt = False
For x = 2 To Len (PString)-1
If Mid (PString, x, 1) = "@" Then Plt = True
If Mid (PString, x, 1) = "." And Plt = True Then Pgt = True
Next
If Plt = True And Pgt = True Then
IsEmail = True

IsEmail = False
End if
End Function
