The dynamic screen classes allow you to incorporate advanced screen functionality into your MFC applications.
The fundamental difference of these classes are that they work with the actual resource in your executable, this means that users of your applications can alter screens that have been designed by you using the MFC resource editor, they can make changes at run time.
These classes are ideal if you develop/are developing applications that require the ability to have additional fields that can be defined by users to store data that is unique to them, or perhaps to remove some of the fields which you have anticipated they may need.
The classes are designed so they are easily incorporated into your existing applications; this allows your existing programs to be modified quite quickly to incorporate the functionality. The classes based on templates and will work with dialogs, views and property pages.
