MapControlClass Class

Esri MapControl

Product Availability

Available with ArcGIS Engine.

Description

The MapControl encapsulates the Map CoClass and provides additional properties, methods and events for: managing the general appearance, display properties and map properties of the control; adding and managing data layers within the control; loading map documents into the control; dropping data onto the control from other applications; and tracking shapes and drawing to the display.

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.

Remarks

The MapControl uses a ScreenDisplay as the display object for drawing and will therefore react to the same keyboard and mouse actions as the ScreenDisplay object. 

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