Hello guys, I'm having troubles getting the correspondent IDataset value from a list of IDatasetName objects. Is there an easy way to do it? The simple QI from one another always returns null for me.                 public IDataset GetDataset(string targetDatasetName)         {             if (DatasetNames.Count <= 0)                 GetDatasetNames();             IDatasetName datasetName = DatasetNames.Find(IsDatasetName(targetDatasetName));             IDataset dataset = datasetName as IDataset; // this always returns null.             if (dataset == null)                 throw new DatasetHandlerException(GeodatabaseMessages.DatasetCouldNotBeFound);             return dataset;         } Ideas? ...

hello guys I'm having trouble with some unit testing here. Check this out (all are snippets, not everything is in the same class). This is my constructor:         public Memorial(PolygonClass perimeter)         {             if (!perimeter.IsClosed)                 throw new ArgumentException(Messages.PolygonOpen);             if (perimeter.IsEmpty)                 throw new ArgumentException(Messages.PolygonEmpty);             if (!perimeter.IsSimple)                 throw new ArgumentException(Messages.GeometrtyMustBeSimple); // usually getting an error here             if (!OnlyLineSegments(perimeter))                 throw new ArgumentException(Messages.PolygonWithCurves);             this._Perimeter = perimeter;             this._NorthPoint = FindNorthenPoint();             this._DistancesAndAzimuths = new List<IMeasure>();         } Here is the unit test:         [TestMethod]         public void TestFindNorthernPoint_SquareCC()         {             this.memo1 = new Memorial(BuildSquareCC());             IPoint p = new PointClass();             p.PutCoords(1, 1);             Assert.AreEqual(p.X, memo1.NorthPoint.X);             Assert.AreEqual(p.Y, memo1.NorthPoint.Y);         }         private PolygonClass BuildSquareCC()         {             object _missing = Type.Missing;             IPoint p1 = new PointClass();             p1.PutCoords(0, 0);             IPoint p2 = new PointClass();             p2.PutCoords(0, 1);             IPoint p3 = new PointClass();             p3.PutCoords(1, 1);             IPoint p4 = new PointClass();             p4.PutCoords(1, 0);             IPoint p5 = new PointClass();             p5.PutCoords(0, 0);             PolygonClass polygon = new PolygonClass();             polygon.AddPoint(p5, ref _missing, ref _missing);             polygon.AddPoint(p4, ref _missing, ref _missing);             polygon.AddPoint(p3, ref _missing, ref _missing);             polygon.AddPoint(p2, ref _missing, ref _missing);             polygon.AddPoint(p1, ref _missing, ref _missing);             for (int i = 0; i <= polygon.PointCount - 1; i++)             {                 Console.WriteLine("X: {0}; Y: {1}", polygon.get_Point(i).X.ToString(), polygon.get_Point(i).Y.ToString());             }             return polygon;         } So, are CC polygons NOT simple? Am I doing something wrong?? Thanks ... View more

I'm having issues with users exporting shapefiles from our corporate database and I wish to disable some tools that allow the user to do this. One of them being Right click on layer -> export data. How I can accomplish that? Also, how can I block an ArcToolbox tool? Is it possible? I was thinking to implement some sort of event listener and check for each tool/guid I want to disable. Thanks.
