MFC Support in ATL Projects

  • Artigo

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at MFC Support in ATL Projects.

If you select Support MFC in the ATL Project Wizard, your project declares the application as an MFC application object (class). The project initializes the MFC library and instantiates a class (class ProjName) that is derived from CWinApp.

This option is available for nonattributed ATL DLL projects only.

class CProjNameApp : public CWinApp  
{  
public:  
 
// Overrides  
    virtual BOOL InitInstance();
virtual int ExitInstance();
DECLARE_MESSAGE_MAP() 
};  
 
BEGIN_MESSAGE_MAP(CProjNameApp, CWinApp)  
END_MESSAGE_MAP()  
 
CProjNameApp theApp;  
 
BOOL CProjNameApp::InitInstance()  
{  
    return CWinApp::InitInstance();

}  
 
int CProjNameApp::ExitInstance()  
{  
    return CWinApp::ExitInstance();

}

You can view the application object class and its InitInstance and ExitInstance functions in Class View.
