VB .net application invoking a Siebel Inbound WS

Hi all -

I have configured a couple of Siebel 7.8 Web Services and also generated
the WSDL files. 

Now I am trying to consume those Web Services from a VB .net application
based on VS 2005. Does anyone have any experience doing this? If so, can
you please provide some code examples (if available)?
 
Thanks
