This member function is called by InitInstance to accept the parameters passed from the CCommandLineInfo object identified by rCmdInfo, and perform the indicated action.

      BOOL ProcessShellCommand(
   CCommandLineInfo& rCmdInfo 


A reference to a CCommandLineInfo object.

Nonzero if the shell command is processed successfully. If 0, return FALSE from InitInstance.

When you start a new MFC project using the Application Wizard, the Application Wizard will create a local instance of CCommandLineInfo, and then call ProcessShellCommand and ParseCommandLine in the InitInstance member function. A command line follows the route described below:

  1. After being created in InitInstance, the CCommandLineInfo object is passed to ParseCommandLine.

  2. ParseCommandLine then calls CCommandLineInfo::ParseParam repeatedly, once for each parameter.

  3. ParseParam fills the CCommandLineInfo object, which is then passed to ProcessShellCommand.

  4. ProcessShellCommand handles the command-line arguments and flags.

The data members of the CCommandLineInfo object, identified by CCommandLineInfo::m_nShellCommand, are of the following enumerated type, which is defined within the CCommandLineInfo class.

enum {







For a brief description of each of these values, see CCommandLineInfo::m_nShellCommand.
