public interface IIdentify2
extends Serializable

Provides access to members that set the current scale of the display.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Method Summary

IArray	identify(IGeometry pGeom, ITrackCancel pTrackCancel) Identifies objects at the specified location.
void	setScale(double rhs1) The current scale of the display.

Method Detail

identify

IArray identify(IGeometry pGeom,
                ITrackCancel pTrackCancel)
                throws IOException,
                       AutomationException

Identifies objects at the specified location.

Remarks

When the IIdentify interface is on a map layer, the Identify method returns an array of FeatureIdentifyObject objects.

On a FeatureIdentifyObject, you can do a QI to the IIdentifyObj interface to get more information about the identified feature. The IIdentifyObj interface returns the window handle, layer, and name of the feature; it has methods to flash the feature in the display and to display a context menu at the Identify location.

This method performs an identify operation with the provided geometry. When identifying layers, typically a small envelope is passed in rather than a point to account for differences in the precision of the display and the feature geometry.
