CWinApp::OnFileOpen

Implements the ID_FILE_OPEN command.

afx_msg void OnFileOpen( );

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.
