In Visual Studio (we use 2005 for SharePoint 2007), to use Web service, you can right click on a project and select Add Web Reference. However, we use SharePoint Designer (2007) to add custom ASP.NET code using C# and there is no open to add Web Reference to use in the code.
Solution: Add Web Reference on the fly (dynamically). We created a class WebServices with CallWebService function to add Web reference to invoke any Web service method.
Usage: see upcoming blog...
