// ==========================================================================

// Header file : OXResultPart.h

// //////////////////////////////////////////////////////////////////////////

// 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)

//	YES	Persistent objects (saveable on disk)      
//	NO	Uses exceptions

// //////////////////////////////////////////////////////////////////////////

// Desciption :         
//	This class encapsulates a single result code and its message

//	An object can be constructed from an HRESULT value.
//	Now the accompanying message will be retrieved from the message resource
//	When optional parameters are needed they can be supplied

//	A group of these object can be stored in a COXResultObj

// Remark:

// Prerequisites (necessary conditions):
