Lesson 30. Creating COM Objects Using ATL

In this chapter, you'll look at creating custom COM objects using the Active Template Library (ATL). You'll learn how to use the Interface Definition Language (IDL) to define interfaces that go beyond the basic types supported by IDispatch. You'll examine how structures, enumerations, and unions can be passed over COM interfaces. And finally, you'll see an example of a COM client and server that pass structures and enumerations through a custom interface.
