C# CreateFeaturesFromTextFile

JimHenry — Thu, 05 Aug 2010 15:29:25 GMT

I am new to the ESRI SDK and I am looking to automate my ArcView GUI based task. I am not sure if I am even on the right track?

using System.Linq;
using System.Text;
using System.Windows.Forms;
using ESRI.ArcGIS.SampleTools;
using ESRI.ArcGIS.Geoprocessor;
using ESRI.ArcGIS.esriSystem;

namespace EsriTest
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            CreateFeaturesFromTextFile a = new CreateFeaturesFromTextFile();
            a.Input_Text_File = @"C:\in.txt";
//in combile stops here with error 80040111
            Geoprocessor g = new Geoprocessor ();
            g.AddToolbox(a.Alias);
//I knew the below was a problem but I am stuck
            //g.Execute(new IGPProcess(), new ITrackCancel());
        }

    }
}

Found this link for my first error:
http://blogs.esri.com/Dev/blogs/arcgisdesktop/archive/2009/12/01/Migrating-to-Engine-9.4-and-using-the-VersionManager.aspx

Summary:
At 10, ESRI has introduced the new RuntimeManager Class. This class can be used to interrogate which products are on the machine and then bind to a product.

reference ESRI.ArcGIS.Version
ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Engine);

For anyone the cares here is the working solution:

using System;
using System.Collections;
using System.Text;
using ESRI.ArcGIS.Geoprocessor;
using ESRI.ArcGIS.esriSystem;
using ESRI.ArcGIS.SampleTools;

namespace EsriTest
{
    class EsriTest
    {
        static void Main(string[] args)
        {
            ESRI.ArcGIS.RuntimeManager.Bind(ESRI.ArcGIS.ProductCode.Engine);

            Geoprocessor GP = new Geoprocessor();
            CreateFeaturesFromTextFile a = new CreateFeaturesFromTextFile();
            a.Input_Text_File = @"C:\in.txt";
            a.Output_Feature_Class = @"dataOut.shp";
            a.Output_Feature_Class_Spatial_Reference = @"C:\Program Files\ArcGIS\Coordinate Systems\Geographic Coordinate Systems\World\wgs 1984.prj";
            a.Input_Decimal_Separator = ".";
            RunTool(GP, a, null);
        }

        private static void RunTool(Geoprocessor geoprocessor, IGPProcess process, ITrackCancel TC)
        {

            // Set the overwrite output option to true
            geoprocessor.OverwriteOutput = true;

            // Execute the tool
            try
            {
                geoprocessor.Execute(process, null);
                ReturnMessages(geoprocessor);

            }
            catch (Exception err)
            {
                Console.WriteLine(err.Message);
                ReturnMessages(geoprocessor);
            }
        }

        // Function for returning the tool messages.
        private static void ReturnMessages(Geoprocessor gp)
        {
            if (gp.MessageCount > 0)
            {
                for (int Count = 0; Count <= gp.MessageCount - 1; Count++)
                {
                    Console.WriteLine(gp.GetMessage(Count));
                }
            }

        }
    }
}

I cannot locate/add ESRI.ArcGIS.Version assembly.

I am using ArcGIS Desktop 10 with VS 2008 on Windows 7.

Please help.

I'm just struggling to find the Execute Method that takes IGPProcess as an input.

I'm stuck with the one that takes a string input, and when I use that, my application just kind of fades away. the code I'm working with currently:

    class ExportGeoprocessing
    {
        GeoProcessor gp = new GeoProcessor();
        
        IGPUtilities gputils = new GPUtilitiesClass();
        public void ExecuteGeoprocessingTask(String infeature, String outfeature,
            IWorkspace outworkspace, IFeatureWorkspace inputworkspace, IFields fields, Hashtable fieldpairings)
        {
            
            String extension = outfeature.Split('.')[1];
            IVariantArray parameters = null;
            object severity = 2;
            switch (extension)
            {
                case("dbf"):
                    parameters = BuildParameterObjectForTable(infeature, outfeature, outworkspace, inputworkspace, fields, fieldpairings);
                    break;
                case("shp"):
                    parameters = BuildParameterObjectForShapefile(infeature, outfeature, outworkspace, inputworkspace, fields, fieldpairings);
                    try
                    {
                        gp.Execute("FeatureclassToFeatureclass_conversion", parameters, null);
                    }
                    catch
                    {
                        Console.WriteLine(gp.GetMessages(ref severity).ToString());
                    }
                    break;
            }
        }

        private IVariantArray BuildParameterObjectForShapefile(String infeature, String outfeature,
            IWorkspace outworkspace, IFeatureWorkspace inputworkspace,IFields fields, Hashtable fieldpairings)
        {
            IVariantArray parameters = new VarArrayClass();
            IName fcname = GetFeatureName(infeature, outfeature, (IWorkspace)inputworkspace);
            IFeatureClass infc = inputworkspace.OpenFeatureClass(infeature);

            IGPFieldMapping fieldmapping = BuildOutputFieldMapping(fcname, fields, fieldpairings);

            parameters.Add(infc);
            parameters.Add(outworkspace); //make a string object
