Application framework


Application Framework:
VC++ provides GUI Interface to develop an application in windows environment. VC++ is having Microsoft foundation class facility to develop an application. The environment of VC++ is very user friendly for developing an application.

·        MFC (Microsoft Foundation Classes):
The MFC contains the Microsoft windows API. These API are developed in the C++ language and implemented as interface of MFC library.

·        Standard Structure:
Like any other programming language, it has its own program structure. To run any program in VC++ must have WinMain function.

·        Small and Fast:
In early days, the programs were used to develop in 16 bit. The windows programmes are developed in 32 bit so programs are faster than old programming.

·        Reduce coding drudgery:
The visual C++ resource editor, AppWizard and class wizard reduced the time needed to write code.
For Ex:
1.     AppWizard generates skeleton code for application.
2.     Class wizard generate prototype and function body for message handle.

Application Framework provides following facilities:
                                                        i.            Resource editor
                                                      ii.            The C/C++ compiler
                                                    iii.            Source code editor
                                                   iv.            Resource compiler
                                                     v.            Linker
                                                   vi.            Debugger
