Can I use Activator.CreateInstance when declaring a new Geoprocessor object??

[JoshV]

I've used the below lines of code to start creating a new geodatabase but I need to do something similar for declaring a new Geoprocessor object.  I keep getting an error in my C# code right at Geoprocessor gp = new Geoprocessor.  I'm guessing this is because of the new keyword so I'm hoping I can use something similar to below code

Type t = Type.GetTypeFromProgID("esriDataSourcesGDB.AccessWorkspaceFactory.1");//("{DD48C96A-D92A-11D1-AA81-00C04FA33A15}");
                    System.Object obj = Activator.CreateInstance(t);

Just in case I'm wrong and the new keyword is not the issue, here is the error I'm getting at Geoprocessor gp = new Geoprocessor();

Creating an instance of the COM component with CLSID {5374EC4C-1AA2-4829-A811-DE624ECEC23F} from the IClassFactory failed due to the following error: 80010105

I am developing ArcMap extensions quite frequently, but it was never a problem to create an instance in C# with the new keyword. May be you are developing an ArcGIS engine application? In this case, I would try to check out a license before instantiating the geoprocessor object.

http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#//00010000043p000000

The Geoprocessor is not listed, so using the Activator class is not the right way.

Best regards, Stefan

I'm using a Standalone C# console application so using the activator class was correct nearly everywhere I had to replace a "new" keyword.  I have already used aoinitialize to checkout a license.  If you know of any other suggestions please let me know.

Thanks

Below is the code from a Windows service that I wrote a while back.  I fully qualified the class names to avoid confusion with the old Geoprocessor class in the Geoprocessing library.

            ESRI.ArcGIS.ConversionTools.FeatureClassToFeatureClass fcToFcTool = new ESRI.ArcGIS.ConversionTools.FeatureClassToFeatureClass();
            fcToFcTool.in_features = featureLayer;
            fcToFcTool.out_path = outputDirectory;
            fcToFcTool.out_name = newTableName;
            if (!string.IsNullOrEmpty(query))
                fcToFcTool.where_clause = query;

            Geoprocessor gp = new ESRI.ArcGIS.Geoprocessor.Geoprocessor();
            gp.Execute(fcToFcTool, null);

Hi Neil-  Thanks for the response.  I have used nearly the same exact code before in my other functions and not got an error but for some reason I am still getting that IClassFactory error even if I use the fully qualified geoprocessor name.  Any suggestions?

Sounds like this might be an install issue ... if you search your registry, do you find this key?

If not, consider re-installing.

Hi Kirk-

I did a search in my registry and found that key in esriGeoprocessing.GeoProcessor.   This is puzzling.. Thoughts?

[KirkKuykendall]

Here's the key I have (on Vista64):
HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{5374EC4C-1AA2-4829-A811-DE624ECEC23F}

Do you have this key (or its 32 bit equivalent) ?

Does this code work for you?

public static void TestGp()
{
    Guid g = new Guid("5374EC4C-1AA2-4829-A811-DE624ECEC23F");
    Type t = Type.GetTypeFromCLSID(g);
    Debug.Print(t.ToString());
    GeoProcessor gp = Activator.CreateInstance(t) as GeoProcessor;
    Debug.Print(gp.OverwriteOutput.ToString());
    
}

Hi Kirk-

2 questions: What is the GUI for the Geoprocessor object not GeoProcessor?  I was using Geoprocessor object because its execute method only takes 2 arguments.

If I have to use GeoProcessor then the first parameter required is string Name.  What is Name?  The Name of the tool?  FeatureClassToFeatureClass_Conversion?
