Soap,Visual Basic 6.0, howto   

Hi,
I'm new here, and would be great if someone could help a little bit.
I'm trying to find a simple example how to make simple search for towns 
giving just the town name. I'm looking for example in VB 6.0 using for 
example Soap 3.0.
I manage to wrote some code but I'm getting the error:
specification.DataSourceName  cannot be null.

My code looks like this:
-----------------------------------------------------------------
Dim soapclient As New SoapClient30
Dim retList As IXMLDOMNodeList
Dim Results As Variant
' 1st method
    soapclient.MSSoapInit2 
"http://staging.mappoint.net/standard-30/mappoint.wsdl", "", "FindService", 
"FindServiceSoap", "http://s.mappoint.net/mappoint-30/"
' 2nd method
    soapclient.MSSoapInit 
"http://staging.mappoint.net/standard-30/mappoint.wsdl", "FindService", 
"FindServiceSoap"
    
    soapclient.ConnectorProperty("AuthUser") = "*****"
    soapclient.ConnectorProperty("AuthPassword") = "******"
    soapclient.ConnectorProperty("WinHTTPAuthScheme") = 24

'----------
    Set Results = soapclient.Find("Szczecin")
'----------
    'Set retList = soapclient.Find("Szczecin")
-------------------------------------------------------------------

So how to set this DataSourceName , and is there any other way to do this if 
so any example would be an advantage
thanks in advance
