Before you work through the steps of implementing Container, you might want to try out the completed application. This will help you appreciate OLE container functionality from a user’s point of view.
Other example container applications are provided on the Visual C++ distribution CD-ROM. Some of these samples were written using MFC, and others were written using the SDK. You can easily install the files needed to build and examine these sample applications.
Finally, the best examples are those world-class applications that support OLE and ActiveX today. These are the applications you will ultimately want to test your application against.
