CCommandLineInfo::m_nShellCommand
Indicates the shell command for this instance of the application.
m_nShellCommand;
Remarks
The type for this data member is the following enumerated type, which is defined in the CCommandLineInfo class.
enum{
FileNew,
FileOpen,
FilePrint,
FilePrintTo,
FileDDE,
AppRegister,
AppUnregister,
RestartByRestartManager,
FileNothing = -1
};
For a brief description of these values, see the following list.
CCommandLineInfo::FileNew Indicates that no file name was found on the command line.
CCommandLineInfo::FileOpen Indicates that a file name 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::AppRegister Indicates that the /Register or /Regserver flag was found on the command line and the application was asked to register.
CCommandLineInfo::AppUnregister Indicates that the /Unregister or /Unregserver application was asked to unregister.
CCommandLineInfo::RestartByRestartManager Indicates that the application was restarted by the restart manager.
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 it calls ProcessShellCommand. ProcessShellCommand is called by the InitInstance( ) of all CWinApp derived classes.
Example
// 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;
