The GUID property is a read-only string holding the class Channel object's globally unique identifier. This value uniquely identifies the channel from others. A list of GUID values is normally stored in the Personalization and Membership directory service to identify the channels a user has selected to include or exclude for viewing.
Type
String (VT_BSTR) (read only)
Default
This property is generated automatically during the creation of a Channel object.
Remarks
When a user selects a channel for personal subscriptions, you can use the UserObjects COM object (ProgID: Membership.UserObjects) to store the value. The name of the user property in the directory database is normally stored in a Project object's SelectionListPropName property. These GUID values can be retrieved as well by using the UserObjects object and passed to an instance of the CDFGenerator object for generation of the personalized CDF stream.
