Hi, Shana, Chris Smith and Michael It end up the error message "An unknown error has occurred" actually come from our web application, not the geocoding service. for the wrong results happened occasionally, we confirm that the wrong geocoding results is due to the incorrect data that was used to build the locator years ago. the current data is correct but the fields was updated and do not match the locator. so we could rebuild locator at the moment. we believe after use updated feature class and rebuild the locator, the service will return the correct results. Thank you for all your help and efforts. Happy New Year. Juncheng

I am working with a Geometric Network, I would like to find the shortest path for two given points and get the path geometry. I know the Utility Network Analyst does this. but it only draw the path, but I need to get the geometry of the path regardless of the flow direction. Is anyone have such experience? Any hint or any piece of codes would be very appreciated. thank you in advanced.

Thank you very much, this solved my problem, according to application logic, for some specific area, there can be NaN for Z.

Hi, everyone I am trying to create the polyline z features in geodatabase, when I crete for 2 dimensional lines, I can always use code: IFeatureBuffer fb = featureCls.CreateFeatureBuffer(); ... fb.shape = m_polyline; featureCursor.Insert(fb); ... however, when deal with "polyline Z" the the above code throw exception "Item could not be found in this collection", can anyone help? thank you very much. the codes I did looking the following: IPointCollection zpointColl = (IPointCollection)centerline; zawre = (IZAware)centerline; zawre.ZAware = true; centerline.FromPoint = startPoint; centerline.ToPoint = EndPoint; centerline.SpatialReference = spaRef; az = (IZ)zawre; az.MultiplyZs(1); az.InterpolateZsBetween(0, 0, 0, (zpointColl.PointCount - 1)); //Polyline always one part az.CalculateNonSimpleZs(); try { IFeatureBuffer fb = CenterlineClass.CreateFeatureBuffer(); fb.set_Value(fb.Fields.FindField("LineID"), pipeID); fb.set_Value(fb.Fields.FindField("Length"), length); //fb.Shape = centerline; // (IGeometry)az int i = fb.Fields.FindField("shape"); fb.Shape = centerline; //This line always throw exception Item could not be found in this collection centerLineCur.InsertFeature(fb); } catch (Exception ex) { MessageBox.Show(ex.Message); }

Hi, everyone I need to find the way to get the intersect points between a polyline and and a circle using ArcObjects 10, my C# codes something like this: ITopologicalOperator topo = (ITopologicalOperator)baseline; IGeometry intersects = topo.Intersect(circle, esriGeometryDimension.esriGeometry0Dimension); IMultipoint multipoint = (IMultipoint)intersects; IPointCollection Pts = (IPointCollection)multipoint; but the function Intersect clash all the time, it gave me error like this: Err: Exception from HRESULT: 0x80040585 can anyone help? thank you very much.

I am trying to develop an Mobile GIS application, when I add map control to the mobile form, it add mobileCache automatically, I set mobile cache's storagePath and paste mobile cache file (layer0.bin and MapSchema.bin, this two cache file were created from ArcToolbox 9.3) in it, but when I run the application, the map control does NOT display the map, instead, its name "map1" is displays there, can any one help? thank you very much. I am using Mobile SDK 10, and read the map from ArcGIS server 9.3 map service. Is this a problem?
