PhoneBook stored in XML

This code is an ActiveX DLL that encapsulates the functionality of a phone book. It can be used to manage phone book data such as a person's information and the telephone numbers. The data that is stored in the Phonebook component can then be stored to an XML file using the MS XML Parser. This can component can then read the XML file using the MS XML parser into the component's properties. There is an object hierarchy in place that lets any user of this DLL loop through all the phone numbers of a single person and/or loop through all the people in the phonebook.
