Saves the object's properties into a client-supplied property bag.
STDMETHOD(Save)(
   LPPROPERTYBAG pPropBag,
   BOOL fClearDirty,
   BOOL fSaveAllProperties

Remarks
ATL uses the object's property map to store this information. By default, this method saves all properties, regardless of the value of fSaveAllProperties.
See IPersistPropertyBag::Save in the Windows SDK.
