Jag har försökt sätta ihop en authentificering på en webservice som senare skall kontrollera användarnamn och lösenord i en databas, vilket än så länge inte finns med i koden. Problemet är när den ska kolla om strHeader Is Nothing och får då felmeddelandet som finns bifogat längst ner i meddelandet.

Jag har tagit den mesta av denna kod i "Sams Lär dig Asp.Net på 3 veckor" sidan 588.

Tacksam för all hjälp jag kan få!

<code>
Imports System
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.Services
Imports System.Web.Services.Protocols

Namespace TESTLOGIN

Public Class Authenticator : Inherits SoapHeader
Public username As String
Public password As String
End Class

Public Class SecureDatabaseService : Inherits WebService
Public strHeader As Authenticator

<WebMethod(), SoapHeader("strHeader")> Public Function GetUpdates() As String

If strHeader Is Nothing Then
Throw New Exception("Error: Incorrect StreamVision Username or Password")
End If

End Function

End Class

End Namespace

</code>
