// ==========================================================================
// Class Specification : COXUNCStandardActor
// ==========================================================================
// Header file : OXUNCStandardActor.h
// Version: 9.3
// //////////////////////////////////////////////////////////////////////////
// Properties:
// NO Abstract class (does not have any objects)
// YES Derived from CObject
// NO Is a Cwnd.
// NO Two stage creation (constructor & Create())
// NO Has a message map
// NO Needs a resource (template)
// NO Persistent objects (saveable on disk)
// NO Uses exceptions
// //////////////////////////////////////////////////////////////////////////
// Desciption :
// This class works together with the COXUNC class. The COXUNC class encapsulates
// the data, whereas this COXUNCStandardActor class encapsulates the actual actions
// (moving, deleting etc.)
// Remark:
// All result codes are full HRESULTs. Win32 error are converted through
// the HRESULT_FROM_WIN32 macro
// Return values are only valid when the result code is SUCCEEDED
// Prerequisites (necessary conditions):
