Hello,

could anyone tell me just looking at the code where could there be a bug? The original code that I managed was functional, but I wanted to simplify the code even more, and it no longer works.

protected override async void OnClick() { FeatureLayer fl = MapView.Active.Map.FindLayers("O_Klad_ZTM10").First() as FeatureLayer; if (fl == null) return; await QueuedTask.Run(() => { QueryFilter qf = new QueryFilter(); string whereClause = "ZTM10_nom LIKE '0602%'"; qf.WhereClause = whereClause; fl.Select(qf); }); var path = @"D:\PomocnaVrstva.shp"; var extent = 200; // CalculateBuffer(fl, path, extent, "Meters"); object[] listParameter = {fl, path, extent, "Meters"}; await StartGp("analysis.Buffer", listParameter); int indexNumber = 0; var mapView = MapView.Active; if (mapView != null) { Uri shpUri = new Uri(path); await QueuedTask.Run(async ()=>//from here it no longer takes place { Layer shapeLayer = LayerFactory.Instance.CreateLayer( shpUri, mapView.Map, indexNumber, "PomocnaVrstva"); // var selectedLayer = mapView.GetSelectedLayers()[0] as FeatureLayer; není potřeba var shpLayer = shapeLayer as FeatureLayer; var pathDis = @"D:\DissolvePomocnaVrstva"; //// DissolveLayer(shpLayer, pathDis); object[] listOfPara = {shpLayer, pathDis}; await StartGp("management.Dissolve", listOfPara); FeatureLayer dissFeat = MapView.Active.Map.FindLayers("DissolvePomocnaVrstva").First() as FeatureLayer; var overlapType = "COMPLETELY_WITHIN"; var selectionType = "NEW_SELECTION"; var pathErase = @"D:\ErasePomocnaVrstva"; //SelectLayer(featLayer, overlapType, dissFeat, selectionType); FeatureLayer featLayer = MapView.Active.Map.FindLayers("O_Klad_ZTM50").First() as FeatureLayer; object[] listOfParameter = { featLayer, overlapType, dissFeat, selectionType }; await StartGp("management.SelectLayerByLocation", listOfParameter); //EraseLayer(dissFeat, featLayer, pathErase); object[] parameterList = { dissFeat, featLayer, pathErase }; await StartGp("analysis.Erase", parameterList); }); } } private static async Task StartGp(string funcArc, object parame) { var parameters = Geoprocessing.MakeValueArray(parame); FunctionPart(funcArc, parameters); } //private static void CalculateBuffer(FeatureLayer featureLayer, string sOutputPath, double dDistance, string sUnits) //{ // var parameters = Geoprocessing.MakeValueArray(featureLayer, sOutputPath, // string.Format(CultureInfo.InvariantCulture, "{0} {1}", dDistance, sUnits)); // var buffer = "analysis.Buffer"; // FunctionPart(buffer, parameters); //} //private static void DissolveLayer(FeatureLayer featureLayer, string sOutputPath) //{ // var parameters = Geoprocessing.MakeValueArray(featureLayer, sOutputPath); // var dissolve = "management.Dissolve"; // FunctionPart(dissolve, parameters); //} //private static void EraseLayer(FeatureLayer featureLayer, FeatureLayer eraseFeatureLayer, string sOutputPath) //{ // var parameters = Geoprocessing.MakeValueArray(featureLayer, eraseFeatureLayer, sOutputPath); // var erase = "analysis.Erase"; // FunctionPart(erase, parameters); //} //private static void SelectLayer(FeatureLayer featureLayer, string overlapType, FeatureLayer selectFeature, string selectionType) //{ // var parameters = Geoprocessing.MakeValueArray(featureLayer, overlapType, selectFeature, selectionType); // var selectLayer = "management.SelectLayerByLocation"; // FunctionPart(selectLayer, parameters); //} private static async Task FunctionPart(string stringFunc, IReadOnlyList<string> parameters) { try { await Geoprocessing.ExecuteToolAsync(stringFunc, parameters).ConfigureAwait(false); } catch (Exception ex) { Debug.WriteLine(ex.ToString(), Assembly.GetExecutingAssembly().FullName); throw; } }

I will be very grateful for every idea.

Thank you!

@DavidMrázek

When you run this code, what error do you get?

I'm curious about the use of "ConfigureAwait(false)"....are u trying to change the synchronization context from the QueuedTask? FWIW QueuedTask It is a single thread _by design_......if you remove that statement what happens?

There were three mistakes and terribly unnecessary:
1. suffix at path to files
2. u buffer should be input conditions three, I wrote two and that is the size of the clip and the unit separately
3. object list is different than parameter in StartGp (object [] and object)
