TOCControlClass Class

Esri TOCControl

Product Availability

Available with ArcGIS Engine.

Description

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.

Extended Error Information

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.
