The type for this data member is the following enumerated type, which is defined within the CCommandLineInfo class.

enum{

FileNew,

FileOpen,

FilePrint,

FilePrintTo,

FileDDE,

FileNothing = -1

};

For a brief description of these values, see the following list.

CCommandLineInfo::FileNew Indicates that no filename was found on the command line.
CCommandLineInfo::FileOpen Indicates that a filename was found on the command line and that none of the following flags were found on the command line: /p, /pt, /dde.
CCommandLineInfo::FilePrint Indicates that the /p flag was found on the command line.
CCommandLineInfo::FilePrintTo Indicates that the /pt flag was found on the command line.
CCommandLineInfo::FileDDE Indicates that the /dde flag was found on the command line.
CCommandLineInfo::FileNothing Turns off the display of a new MDI child window on startup. By design, Application Wizard-generated MDI applications display a new child window on startup. To turn off this feature, an application can use CCommandLineInfo::FileNothing as the shell command when calling ProcessShellCommand. ProcessShellCommand is called by the InitInstance( ) of all CWinApp derived classes.

Пример

// From CMyWinApp::InitInstance

// Parse command line for standard shell commands, DDE, file open
CCommandLineInfo cmdInfo;
ParseCommandLine(cmdInfo);

// DON'T display a new MDI child window during startup!!!
cmdInfo.m_nShellCommand = CCommandLineInfo::FileNothing;

// Dispatch commands specified on the command line
if (!ProcessShellCommand(cmdInfo))
   return FALSE;
