New Post: Exception when using Shapefile.Table.Query()

Hi,

I am using MapWinGis OCX 4.8.8 in a VS2010 C# project to evaluate the control for use in our c#app. Up until now I have been really impressed and I am hoping this is an easy one:

The app has a textbox where the end user can input some text. This 'text' is then used in a query against one of the shapefiles loaded into the control.

Today, the code began throwing an exception on my development machine and I do not know why. I have attempted:
-reinstalling the 'MapWinGIS-only-v4.8.8SR-32bit-installer.exe'
-restarting the machine.
-uninstalling the newly installed TortoiseSVN after attempting and failing to compile the OCX source.


Any ideas how I can get back to the state where this app succeeds in its call to .Table.Query()?

TIA

Here is the code:

        string error = "";
        object result = null;

        // the text values must be placed in quotes; we need to shield them with \ sign in C#
        // fields are must be placed in square brackets
        string query = "[PID] = \"" + textBoxParcelID.Text + "\"";
        fParcels.SelectNone();
        try
        {
            if (fParcels.Table.Query(query, ref result, ref error))
            {
                int[] shapes = result as int[];
                if (shapes != null)
                {

                    for (int i = 0; i < shapes.Length; i++)
                    {
                        fParcels.set_ShapeSelected(shapes[i], true);

                        MapWinGIS.Shape shp = fParcels.get_Shape(shapes[i]);
                        string text = fParcels.get_CellValue(8, shapes[i]).ToString();
                        MapWinGIS.Point pnt = shp.Centroid;
                        fParcels.Labels.AddLabel(text, pnt.x, pnt.y, 0.0, -1);
                    }
                    axMap1.ZoomToSelected(layerHandleParcels);
                    MapWinGIS.Extents extentCurrent = (MapWinGIS.Extents)axMap1.Extents;
                    axMap1.ZoomOut(0.5);

                }

                //MessageBox.Show("Objects selected: " + fParcels.NumSelected);
            }
            else
            {
                //MessageBox.Show("No shapes agree with the condition.");
            }
        }
        catch (Exception ex)
        {
            MessageBox.Show("Exception:" + ex.Message);
        }

The Exception is: "System.Runtime.InteropServices.SEHException" "External component has thrown an exception"
