HRESULT Save( IStorage* pStorage, BOOL fSameAsLoad );
See IPersistStorage:Save in the Win32 SDK.
Remarks
Saves the object's properties. The ATL implementation delegates to the IPersistStreamInit interface. When Save is first called, it creates a stream named "Contents" on the specified storage. This stream is then used in later calls to Save and in calls to Load.
