Thanks, I will try to find a way to integrate this in my app.
But there is no Autentication ref in the proxy code :(
I have to figure out how and where to place the f.. header in the proxy class.
The web service was not a ASP.NET service so I dont have acces to a .disco or asmx file to help me how to build this proxy class.

The sample client use soap toolkit COM for the client access.
I have to build the equivalent of the 'ClientHeaderHandler' COM object to make this work...

You can do it by the use of wsdl.exe or directly in VS Studio.

In VS Studio you just have to add a WebReference to your project (right click on the project in the solution explorer pane) and a kind of wizzard ask for the address of the web service and create the proxy class for you.
