Description

The Buddy returns the object implementing ITOCBuddy that was passed to the SetBuddyControl method. The Buddy is responsible for handling the ActiveView, and enables the TOCControl to populate itself with maps, layers and symbols.

The SetBuddyControl method will remove any wrapper object that a development environment has added to the control passed to it. As such, the object passed into the SetBuddyControl method may be different from the object returned by the Buddy.
