>If it is derived from SoapClient then it looks as if you could also do this by setting the Destination property to a suitable instance of EndPointReference (but I haven't tried it :-{ )

If you are making reference to something like this, then I can adjust the URL:

    ' Add code here to start your service. This method should set things
    ' in motion so your service can do its work.
    Protected Overrides Sub OnStart(ByVal args() As String)
        Dim lcUrl As String = ""
        Dim loBasicHttpBinding As New System.ServiceModel.BasicHttpBinding()
        Dim loEndpointAddress As System.ServiceModel.EndpointAddress

        ' Get the Web Service URL
        lcUrl = "https://www.mywebsite.com/MyWebServiceDirectory/MyWebService.asmx"

        ' Adjust the URL
        loEndpointAddress = New System.ServiceModel.EndpointAddress(lcUrl)
        oMyClassSoapClient = New MyNamespace.MyClassSoapClient(loBasicHttpBinding, loEndpointAddress)

However, the only problem with that is that we are not allow to use https under that protocol.

I get this error:

The provided URI scheme 'https' is invalid; expected 'http'.
