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.
Interfaces
| Interfaces | Description |
|---|---|
| IClone (esriSystem) | Provides access to members that control cloning of objects. |
| IDatum | Provides access to members that control the properties of all horizontal datums. |
| IDatumEdit | Provides access to members that control the properties of a horizontal datum. |
| IESRISpatialReference | Provides access to members that control the import/export operations components of a spatial reference system. |
| IPersist | Defines the single method GetClassID, which is designed to supply the CLSID of an object that can be stored persistently in the system. IPersist is the base interface for three other interfaces: IPersistStorage, IPersistStream, and IPersistFile. |
| IPersistStream (esriSystem) | |
| ISpatialReferenceInfo | Provides access to members that control the properties common to all components of a spatial reference system. |
