On the Project menu, click Add Web Reference to display the Add Web Reference dialog box.

Enter the URL for a discovery document or the WSDL description of the XML Web service.

For example, the description of a typical XML Web service created with ATL Server and deployed locally can be found using a URL of the following form:

http://localhost/Project/Project.dll?Handler=GenServiceWSDL

Select Add Reference to have SPROXY generate a header file containing a proxy class for the XML Web service. The header will be automatically added to your project so that you can use Class View to view the classes and methods available to you.

Include the SPROXY-generated header in the file or files where you will write the code to access the XML Web service.

Make sure COM is successfully initialized before using the XML Web service proxy class.

Create an instance of the XML Web service proxy class. Either specialize the SPROXY-generated class template using the appropriate XML Web Service Client Archetype, or use the default typedef.

Optionally set proxy settings or use features specific to the proxy class for controlling the connection, authentication, and other settings.

Write code to call the methods on the XML Web service.

Always use the memory manager returned by CSoapRootHandler::GetMemMgr to allocate memory for [out] or [in, out] parameters and SOAP headers, except BSTRs which must always be allocated with SysAllocString, CComBSTR, or a related function or class.
