The INotifyAppStart methods are (as ordered in the virtual function table after the IUnknown methods):
HRESULT AppStarting (VOID);
HRESULT AppStarted (VOID);
The INotifyAppStart interface is implemented in SHDOCVW version 6.0, and IEFRAME version 7.0 and higher.
Though this interface dates from as long ago as 2001, it is still not documented by Microsoft as late as the January 2007 edition of the Windows Software Development Kit (SDK).
