| This class is a sample application which shows how to write or modify the
author and title property of an OLE 2 document. This could be done in two
different ways:
The first approach is to open the OLE 2 file as a POI filesystem
(see class
POIFSFileSystem ), read the summary information property
set (see classes
SummaryInformation and
PropertySet ), write
the author and title properties into it and write the property set back into
the POI filesystem. The second approach does not modify the original POI filesystem, but
instead creates a new one. All documents from the original POIFS are copied
to the destination POIFS, except for the summary information stream. The
latter is modified by setting the author and title property before writing
it to the destination POIFS. It there are several summary information streams
in the original POIFS - e.g. in subordinate directories - they are modified
just the same.
This sample application takes the second approach. It expects the name of
the existing POI filesystem's name as its first command-line parameter and
the name of the output POIFS as the second command-line argument. The
program then works as described above: It copies nearly all documents
unmodified from the input POI filesystem to the output POI filesystem. If it
encounters a summary information stream it reads its properties. Then it sets
the "author" and "title" properties to new values and writes the modified
summary information stream into the output file.
Further explanations can be found in the HPSF HOW-TO.
