enum ENetCfgComponentType;

// ----------------------------------------------------------------------
// Class CLog
//
// Inheritance:
//   none
//
// Purpose:
//   Provides a way to log errors/warnings to
//     - NT EventLog
//     - NT SetupLog (setuperr.log / setupact.log)
//
//   This class hides much of complexity of the EventLog API. In addition
//   the user of this class does not have to first check whether a EventSource
//   has been created in the registry. This class will create one if not found.
//   Also, it is not necessary to call (De)RegisterEventSource for each report.
//
//   Messages are logged to SetupLog only during system install/upgrade
//   Message are always logged to the EventLog
//
//   This class provides function interface that is closer to EventLog API
//   than to the SetupLog API. The EventLog parameter values are mapped to
//   corresponding SetupLog parameters using some helper functions.
//   See nclog.cpp for details.
//
//   The members of this class do not return an error, because this itself is the
//   error reporting mechanism. However, the class has several Trace* functions.
//
// Hungarian: cl
