Webservice Authentication Made Simple

< system.web.services.webservice(description:="authentication
Name:="AD", _
Namespace:=http://Tempuri.org/AD/AD) > _
Public Class VPO
Inherits System.Web.Services.WebService

#Region " Web Services Designer Generated Code "

'Implimentation of the Header Class
Public Authentication As AuthHeader

'The soapheader attribute tells the interface what to do.
< system.web.services.webservice(description:="authentication
CacheDuration:=0, _
Description:="Test Interface with Return", _
EnableSession:=False, _
MessageName:="TestReturn"), _
