Hi all!

I can draw or paint shapes of a shapefile in a MapWnGis AxMap with a for loop.

But if I want to draw shapes one by one, only it draw the last shape, the others change to a small point.

This is a example code:

private void ShowAll()
        {
            if (System.IO.File.Exists(@"D:\Geoposicionamiento\shapes\barcos.shp") == true)
            {
                //barcos.Open(@"D:\Geoposicionamiento\shapes\barcos.shp", null);
                if (barcos.NumShapes == 0)
                {
                    MessageBox.Show("No hay barcos introducidos");
                }
                else
                {                    
                    //iIdShpBarcos = axMap1.AddLayer(barcos, true);
                    for (int i = 0; i < barcos.NumShapes; i++)
                    {
                        ShowOne(i);
                    }
                }
            }
            else
            {
                MessageBox.Show("No existe el fichero en mostrar barcos!");
            }

Well, this procedure works fine. But if I try to work with the ShowOne() func while I insert a shape this doesn't works.

The code for the ShowOne() func is:

private void ShowOne(int i)
        {
            axMap1.set_LayerVisible(iIdShpBarcos, true); 
            axMap1.set_ShapePointType(iIdShpBarcos, i, MapWinGIS.tkPointType.ptTriangleLeft);
            axMap1.set_ShapePointSize(iIdShpBarcos, i, 5);
            axMap1.set_ShapePointColor(iIdShpBarcos, i,
                (UInt32)(System.Drawing.ColorTranslator.ToOle
                (System.Drawing.Color.Red)));
        }

Note: the param of the proc is the ID of the Shape in the shapefile.

After a lot of tests, I think that the problem is in the layer. But I can't correct the problem.

The result is: (The red TriangleLeft is the last shape). The points are the other shapes that change their 'shape' to a point.


Thanks a lot!!

Quick answer: per-shape options aren't supported any more, you should use ShapefileCategories instead. Some hints on how to use them are, for example, here:
