Adding a Generic C++ Class
You can add a generic C++ class by using Class View. A generic C++ class is a class that you define or that is derived from a class that you define.
To add a generic C++ class to a project
In Class View, right-click the project to which you want to add the new class, click Add, and then click Class.
In the wizard, provide a class name, and then define settings or accept the defaults.
To close the wizard and view the new generic C++ class in the project, click Finish.
