Aids in parsing the command line at application startup.
An MFC application will typically create a local instance of this class in the InitInstance function of its application object. This object is then passed to CWinApp::ParseCommandLine, which repeatedly calls ParseParam to fill the CCommandLineInfo object. The CCommandLineInfo object is then passed to CWinApp::ProcessShellCommand to handle the command-line arguments and flags.
You can use this object to encapsulate the following command-line options and parameters:
app /p filename
Print file to default printer.
app /pt filename printer driver port
Print file to the specified printer.
Start up and await DDE command.
Start up as an OLE automation server.
Start up to edit an embedded OLE item.
Informs the application to perform any registration tasks.
Informs the application to perform any un-registration tasks.
Derive a new class from CCommandLineInfo to handle other flags and parameter values. Override ParseParam to handle the new flags.
