The IScope methods are (as ordered in the virtual function table after the IUnknown methods):
HRESULT AddScopeTreeItem (IScopeItem *, IScopeItem **, INT *);
HRESULT RemoveScopeTreeItem (IScopeItem *, IScopeItem **, INT *);
HRESULT Flatten (INT, REFIID, PVOID *);
HRESULT ExpandScopeFromSearchRoots (REFIID, PVOID *);
HRESULT IsItemIncluded (IShellItem *, BOOL *);
HRESULT Clone (REFIID, PVOID *);
HRESULT GetKnownScopeID (GUID *);
in which IScopeItem is an undocumented interface.
The IScope interface is implemented in SHELL32.DLL in the version 6.00 from Windows Vista, and higher.
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.
