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

// Properties:
//	NO	Abstract class (does not have any objects)
//	YES	Derived from CDialog

//	YES	Is a Cwnd.                     
//	YES	Two stage creation (constructor & Create())
//	YES	Has a message map
//	YES/NO  Needs a resource (template)

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

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

// Desciption :         
//	This class is a generic class which can be used for all modeless dialogs

// Remark:
//	The C++ object will de deleted when the the window is destroyed.
//	This is the default behaviour.  If you want to disable this,
//	 specify bAutoDelete = FALSE when constructing the dialog

// Prerequisites (necessary conditions):
//

	//				for custom cleanup such as the deletion of the this pointer.
	// 				Delete self after window has been destroyed, to avoid TRACE
	// 				message in CWnd. This assumes dialog object is created in the heap, 
	// 				not on the stack when you use the m_bAutoDelete parameter!!
