Class ContactGuid

class ContactGuid;

Description

A globally unique identifier enquiry utility.

Each contact item has a unique identifier, stored as a descriptor. It is referred to as the 'UID string'. This is a combination of the unique identifier of the database in which the contact item was created, the contact item ID and the date/time of the contact item's creation. ContactGuid provides a single static exported function to enquire whether an item was created in a specified database.
