This sample project demonstrates how to do two things. First, it shows how to make a DLL. Second, it shows how to load and use a DLL during run-time in your application. Why would you want to do this? Well, you can add programmatic functionality on the fly without having to even restart your application, let alone reboot Windows. It s a very cool concept. Anyway, I couldn t find an example of this anywhere, so I am posting it in hopes that it may be of some use to someone else who is looking for the same thing. If you see any improvements that can be made to this code, please let me know.

说明：  这个源代码讲的是MFC的对话框的应用程序(The source code is MFC dialog about the application)
