The ICommandBarStateSnapshot interface has just the one method (after the IUnknown methods):
HRESULT get_Data (UINT, PBYTE);
The ICommandBarStateSnapshot interface is implemented in IEFRAME version 7.0 only.
This interface is not documented by Microsoft as late as the January 2007 edition of the Software Development Kit (SDK) for Windows Vista.
