regex - Regular Expressions in VbScript?

Does VbScript have a native implementation for Regex? I need to validate e-mail addresses on an old ASP application.

Any pointers would be great.

Since the top answer here is in VB6 I thought I'd add one here in VBScript (since that's what the question is asking for):-

Option Explicit

Function GetEmailValidator()

  Set GetEmailValidator = New RegExp

  GetEmailValidator.Pattern = "^((?:[A-Z0-9_%+-]+.?)+)@((?:[A-Z0-9-]+.)+[A-Z]{2,4})$"

  GetEmailValidator.IgnoreCase = True

End Function

Dim EmailValidator : Set EmailValidator = GetEmailValidator()

Now some tests:-

Response.Write EmailValidator.Test("") = False
Response.Write EmailValidator.Test(" ") = False
Response.Write EmailValidator.Test("somebody@domain.co.uk") = True
Response.Write EmailValidator.Test("someone@domain.com") = True
Response.Write EmailValidator.Test("some.body@domain.co.uk") = True
Response.Write EmailValidator.Test("broken@domain..co.uk") = False
Response.Write EmailValidator.Test("@oops.co.uk") = False
Response.Write EmailValidator.Test("name") = False
Response.Write EmailValidator.Test("name@uk") = False
Response.Write EmailValidator.Test("name@uk") = False
Response.Write EmailValidator.Test("name@domain.abcde") = False
