// Description:
//  The COM and P/Invoke interop code necessary for the managed compound
//  file layer to call the existing APIs in OLE32.DLL.
//
//  Constants related to CompoundFile
//
// History:
//  05/10/2002: RogerCh: Initial creation.
//  07/31/2002: RogerCh: Add LockBytes support, suppress unmanaged code security.
//  05/20/2003: RogerCh: Ported to WCP tree.
//  05/28/2003: RogerCh: Removed name checks - now handled by LongNameManager
//  02/10/2006: YoungGK: Separated all constants related to CompoundFile
