Visual C++ 6 Unleashed

Visual C++ 6 Unleashed

By MICKEY WILLIAMS and David Bennett

Summary

In this chapter, you began to explore Active documents. Active documents owe much to their OLE document heritage. They share many of the same COM interfaces and add a few new ones of their own.

You can implement an Active document in a number of ways. You can use native COM APIs and do most of the work yourself. You can use MFC. This, in fact, is the easiest tool to use. However, MFC applications tend to be large and for that reason are not suited to downloading over the Internet. Finally, you can use the recent ATL, as you saw in the Microsoft sample program ACTIVEDOC. With ATL, you can build smaller executables, but you will have to do a little more work.
