Remarks

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:

Command-line argument	Command executed
app	New file.
app filename	Open file.
app /p filename	Print file to default printer.
app /pt filename printer driver port	Print file to the specified printer.
app /dde	Start up and await DDE command.
app /Automation	Start up as an OLE automation server.
app /Embedding	Start up to edit an embedded OLE item.
app /Register app /Regserver	Informs the application to perform any registration tasks.
app /Unregister app /Unregserver	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.
