Remarks

The HotSpotCollectionEditor class provides a user interface for editing the HotSpot elements of the HotSpotCollection object that is embedded in an ImageMap or a similar control.

The HotSpotCollectionEditor is invoked by selecting the ellipsis button (…) on the HotSpots property in the visual designer's Properties grid.

The CanSelectMultipleInstances method always returns false to indicate that only one object can be selected at a time in the editor. The CreateNewItemTypes method returns an array of types that the editor can create. The HelpTopic property returns the name of the Help topic that the editor displays.
