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.
