Esri TOCControl
The TOCControl displays a 'Table of Contents' view of maps, layers and layer symbology available from the IActiveView and IBasicMap interfaces. The TOCControl works in conjunction with a 'buddy' control or an object implementing IActiveView. A MapControl, PageLayoutControl, SceneControl or GlobeControl can be a 'buddy'. The TOCControl obtains access to the 'buddy' through the ITOCBuddy interface. The TOCControl manages layer visibility and label editing.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

There is no need to declare the TOCControl's outbound interface as described below in most development environments, because the interface is automaticlly implemented.
