CWinApp::OnFileOpen

Implements the ID_FILE_OPEN command.

afx_msg void OnFileOpen( );

Remarks

You must add an ON_COMMAND( ID_FILE_OPEN, OnFileOpen ) statement to your CWinApp class message map to enable this member function. If enabled, this function handles execution of the File Open command.

For information on default behavior and guidance on how to override this member function, see Technical Note 22.

Example

// The following message map, produced by the Application Wizard, binds  
// the File New, Open, and Print Setup menu commands to default 
// framework implementations of these commands.
BEGIN_MESSAGE_MAP(CStdApp, CWinApp)
   // Standard file based document commands
   ON_COMMAND(ID_FILE_NEW, &CWinApp::OnFileNew)
   ON_COMMAND(ID_FILE_OPEN, &CWinApp::OnFileOpen)
   // Standard print setup command
   ON_COMMAND(ID_FILE_PRINT_SETUP, &CWinApp::OnFilePrintSetup)
END_MESSAGE_MAP()
// The following message map illustrates how to rebind the 
// File New, Open and Print Setup menu commands to handlers that 
// you implement in your CWinApp-derived class.   
// Note, you can name the handler CCustomApp::OnFileNew instead of 
// CCustomApp::OnMyFileNew, and likewise for the other handlers, if desired.
BEGIN_MESSAGE_MAP(CCustomApp, CWinApp)
   ON_COMMAND(ID_FILE_NEW, &CCustomApp::OnMyFileNew)
   ON_COMMAND(ID_FILE_OPEN, &CCustomApp::OnMyFileOpen)
   ON_COMMAND(ID_FILE_PRINT_SETUP, &CCustomApp::OnMyFilePrintSetup)
END_MESSAGE_MAP()
