CPROPSET.H

Abstract:
|
|
|
|
Purpose: Used by the compound file property set provider. This code was
|
|
largly taken from some MSVC sample code which was modified
|
|
somewhat in order to support VARIANT type arrays. In general,
|
|
a CPropSet object contains a list of CPropSection objects
|
|
which each contain a list of CProp objects.
