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

// Properties:
//	NO	Abstract class (does not have any objects)

//	YES	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)      
//	YES	Uses exceptions

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

// Description :         
//	This object serves as a message sink for the COXOwnThread object
//	It's important that the COXOwnThread object is deleted by the same
//	thread that instantiation ed the object (the Owner thread).
//	The OnFinalRelease function of COXOwnThread will check which thread 
//	(Owner or Own thread) tries to delete the object. If it is the Own
//	thread, a message is send to this object (which is a data member of 
//	the COWOwnThread object). Because this object is a window created by
//	the Owner thread, the message will be handled by the Owner thread and 
//	consequently the COXOwnThread object can be safely destroyed from here.

// Remark:
//		

// Prerequisites (necessary conditions):
