Database.SummaryInformation property

The SummaryInformation property of the Database object returns a SummaryInfo object that can be used to examine, update, and add properties to the summary information stream.

This property is read-only.


propVal = Database.SummaryInformation

Property value

The maximum number of properties to be added or modified. This parameter is required and used to allocate sufficient working memory during the stream generation. It is not required to store this number of properties. A value of zero must be used if the database is opened read-only to prevent the stream from being updated.


If a value of maxProperties greater than 0 is used to open an existing summary information stream, the Persist method must be called before closing the object. Failing to do this will lose the existing stream information.

If the property fails, you can obtain extended error information by using the LastErrorRecord method.
