Creates a HARN-based transformation.
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.
The HARNTransformation coclass implements the HARN (HPGN) geographic (datum) transformation method. This is a grid-based method. The grids for forty-two states and two territories are available at ArcInfo 8.1.
See the IGridTransformation interface for the parameters.

| IClone | Provides access to members that control cloning of objects. |
| IGeoTransformation | Provides access to members that define a geographic (datum) transformation. |
| IGridTransformation | Provides access to members that control the dataset name for a grid-based transformation. |
| IPersistStream | |
| ISupportErrorInfo | |
| ITransformation | Provides access to members that apply a function (or its inverse) to a set of points or measures. The suffix of each method indicates the type of parameters operated on. |
