A container for defining the Utility Network Analysis extension and describing its current state.
Product Availability
Available with ArcGIS Desktop.
Description
The UtilityNetworkAnalysisExt object provides functionality for analyzing utility networks in ArcMap. In order to use the UtilityNetworkAnalysisExt object, you must have an active ArcMap application, and obtain a reference to the extension object from the ArcMap application.
Supported Platforms
Windows
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.
