SplineWithBarriers: Cannot get it to work.

Discussion created by milton841 on Aug 11, 2011
I have been having fits trying to get SplineWithBarriers to work but to no avail.

My environment:
Windows 7 64 bit
Visual Studio 2010 Team Edition
ArcMap
     Release Version 10.0
     Product Version: 10.0.2.3200
Spatial Analyst License

Should also mention this is C# code.

I have tried all I can think of and everything looks correct except I continue to get an "E_FAIL" exception whenever it is run. I am hoping someone on this forum has done this and is able to point out my problems. Thanks for any and all help.

Following is my full method.

private void DoSplineWithBarriers()
{
     SplineWithBarriers swb = new SplineWithBarriers();

     IWorkspaceFactory wksFact;
     IFeatureWorkspace featWks;
     IFeatureClass inPtsFC;
     IGeoFeatureLayer geoFeatLyr;

     wksFact = new ShapefileWorkspaceFactoryClass();  
     featWks = wksFact.OpenFromFile("C:\\Workarea\\swb", 0) as IFeatureWorkspace;

     inPtsFC = featWks.OpenFeatureClass("pointsFeature");
     geoFeatLyr = new FeatureLayerClass();
     geoFeatLyr.Name = inPtsFC.AliasName;
     geoFeatLyr.FeatureClass = inPtsFC;

     featWks = wksFact.OpenFromFile("C:\\Workarea\\swb", 0) as
                    IFeatureWorkspace;

     IFeatureClass barriers;
     barriers = featWks.OpenFeatureClass("barrierFeature");

     Raster outPutRas = new Raster();

     swb.Input_point_features = (object)inPtsFC;
     swb.Z_value_field = (object)"DEPTH";
     swb.Output_raster = (object)outPutRas;
     swb.Input_barrier_features = (object)barriers;
     swb.Output_cell_size = (object)0;
     swb.Smoothing_Factor = 0.0;
     swb.ToolboxDirectory = "C:\\Program Files (x86)\\ArcGIS\\Desktop10.0\\ArcToolbox\\Toolboxes";

     Geoprocessor gp = new Geoprocessor();
     gp.AddOutputsToMap = false;
           
     try
     {
         gp.Execute(swb, null);
     }

     catch (Exception ex)
     {
         string msg = "";
         msg = String.Format("Exception creating spline:  {0}\r\nStack trace:\r\n{1}",
                                      ex.Message, ex.StackTrace);
     }
}
