Unhandled exception: Server did not recognize the value of HTTP Header SOAPAction

[Hazzard]

I have the following code with errors on the lines as indicated by the ->
and the explanation in the exception details below;

' FORM1.VB
Private Sub LoadCustomersComplete(ByVal ar As IAsyncResult)
Dim ds As DataSet
Dim ws As New testDataAccess.Service1
-> ds = ws.EndGetDataSet(ar) (line 124 as explained in the exception
details below)

which calls the first line in the following REFERENCE.VB file;

Public Funtion EndGetDataSet(ByVal asyncResult As System.IAsyncResult) As
System.Data.DataSet
-> Dim results() As Object = Me.EndInvoke(asyncResult) (line 53 as
explained below)

and here are the exception details;

Any ideas?

Hi,

Firstly, please make sure the webservice is ok. If the service doesn't
work, the client is certain to fail.

Secondly, please check the namespace on the webservice side. Are you using
the following?

<WebService(Namespace := "http://www.contoso.com/")>

If you have any Qs, please reply to this post.

Thank you Parker. The webservice is o.k. It returns a dataset; a diffgram. I
believe it is a namespace-path discrepancy.

Got it. This is one of those cases where it was easier to start a new
project, creating a new virtual directory, and start all over. I was trying
to morph another application and I got its knickers in a twist...
