The IObjectWithAssociationElement methods are (as ordered in the virtual function table after the IUnknown methods):
HRESULT SetAssocElement (IAssociationElement *);
HRESULT GetAssocElement (REFIID, PVOID *);
in which IAssociationElement is an interface whose only known implementations are by SHELL32.
The IObjectWithAssociationElement interface is implemented by the ExplorerFrame.dll and SHELL32.DLL version 6.0 from Windows Vista.
Though new for Windows Vista, this interface is not documented by Microsoft in the January 2007 edition of the Software Development Kit (SDK) for Windows Vista.
