This member function is called by InitInstance to accept the parameters passed from the CCommandLineInfo object identified by rCmdInfo, and perform the indicated action.
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:
After being created in InitInstance, the CCommandLineInfo object is passed to ParseCommandLine.
ParseCommandLine then calls CCommandLineInfo::ParseParam repeatedly, once for each parameter.
ParseParam fills the CCommandLineInfo object, which is then passed to ProcessShellCommand.
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.
For a brief description of each of these values, see CCommandLineInfo::m_nShellCommand.
