Structure of an MFC Application |

|
While creating an MFC application, the first step is to define and create the
application’s main window. An Application is allowed to write inside their own
windows only and not in other program windows. A program’s main window is also
referred to as the mainframe which consists of a menu bar, if there is one. The steps involved can be listed as 1. Create a main window with standard features. 2. Customize other features of the window using a process known as registering a window class with the operating system. 3. Implement the message handling mechanisms In your MFC application, you derive your main window or mainframe class from the MFC class CFrameWnd, which is derived from CWnd; it contains the functionality needed for a main window. Dialog boxes and controls are also windows, which is also derived from CWnd. The application will create an object of the derived mainframe class which will be the main window object. It can have additional behavior that corresponds to any member functions that you define in your mainframe class. In addition the inherited functions from CFrameWnd can be modified by overriding them in your mainframe class. Another mandatory class for every MFC application is an application class which should be derived from the MFC class CWinApp and contains the functionality needed to set up and run the message loop. |
