Using property collections

The Properties interface provides two classes for collections--TPropertySet and TPropertyIDSet. Both classes contain similar member functions for standard actions such as assignment, adding members, and deleting members (as appropriate to the property or property identifier members that they contain).

Use property sets and property identifier sets to retrieve or assign values (properties or property identifiers) from an MPropertyStore instance in a single operation. Using sets instead of individual read or write calls optimize performance.
