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.

Remarks
The AnnotationFeatureClassExtension CoClass manages the drawing of annotation features.
The AnnotationFeatureClassExtension is used to configure the drawing properties and symbology for annoation features.
