MissingCommand CoClass

Missing commands that cannot be created by the ToolbarControl.

Product Availability

Available with ArcGIS Engine.


MissingCommand provides visual feedback about a command on the ToolbarControl that cannot be created, because the *.dll containing the command is either unregistered or has been deleted. The ToolbarControl will automatically replace a command implementation with a MissingCommand. A MissingCommand has a bitmap that resembles a 'no entry' sign and click and tooltip messages providing information about the missing guid and progid.
