Example Webservice Call using Visual Basic .NET:

1. Add Web Reference

First you have to add the webservice as Web Reference to your project.
You can do this using the corresponding menu item: Project->Add Web Reference

This generates a service class that can then be used in your sourcecode.

2. Source code:

        ' creating a new instance
        Dim client As New test.SoapServiceService

        ' calling the test method testIntAdd
        Dim result = client.testIntAdd(1, 2)
