ShapefileWorkspaceFactory Failing In Arc 10

Hi All,

I am writing a utility using C# and Visual Studio 2010 that needs to create a connection to a workspace. I have ArcGIS Desktop 10 Service Pack 2 installed. I have tried two different ways to create a workspace:
In this function call, I pass in "esriDataSourcesFile.ShapefileWorkspaceFactory" as the factoryProgID parameter
        private static SingleValueResult<IWorkspace> OpenWorkspaceFromFile(string fullPath, string factoryProgID)
        {
            SingleValueResult<IWorkspace> result = new SingleValueResult<IWorkspace>();
            try
            {
                Type factoryType = Type.GetTypeFromProgID(factoryProgID);
                IWorkspaceFactory2 factory = (IWorkspaceFactory2)Activator.CreateInstance(factoryType);
                if (!object.Equals(null, factory))
                {
                    IWorkspace workspace = factory.OpenFromFile(fullPath, 0);
                    if (!object.Equals(null, workspace))
                    {
                        result.Success = true;
                        result.ReturnValue = workspace;
                    }
                }
                else
                    result.SetFailure(String.Format(
                        Properties.Resources.NullValueFailureFormat, "WorkspaceFactory"));
            }
            catch (Exception ex)
            {
                result.SetFailure(ex.Message);
            }
            return result;
        }

In this function call I try to spin up a ShapefileWorkspaceFactory directly:

        private static SingleValueResult<IWorkspace> OpenShapefileWorkspace(string fullPath)
        {
            SingleValueResult<IWorkspace> result = new SingleValueResult<IWorkspace>();
            IWorkspaceFactory factory = new ShapefileWorkspaceFactory();
            IWorkspace workspace = factory.OpenFromFile(fullPath, 0);
            if (!Equals(null, workspace))
            {
                result.Success = true;
                result.ReturnValue = workspace;
            }
            return result;
        }

In both cases I am getting the same failure:

{"Retrieving the COM class factory for component with CLSID {A06ADB96-D95C-11D1-AA81-00C04FA33A15} failed due to the following error: 80040111 ClassFactory cannot supply requested class (Exception from HRESULT: 0x80040111 (CLASS_E_CLASSNOTAVAILABLE))."}

In the code where I pass in a factoryProgID it fails on the line with Activator.CreateInstance. In the code where I try to spin up the ShapefileWorkspaceFactory it fails on the line with new ShapefileWorkspaceFactory().

I have added a reference to ESRI.ArcGI.DataSourcesFile to my project and "using ESRI.ArcGIS.DataSourcesFile" to my code file.

This appears to be related to Arc 10, since I have successfully used very similar code in previous versions without problems. Any assistance will be greatly appreciated.

Regards,
Jay

Hi All,

An update to my original posting. The code that tries to spin up the IWorkspaceFactory2 from a factory type (the first code snipped in my post) retrieved from a factoryProgID is also failing with esriDataSourcesGDB.AccessWorkspaceFactory and esriDataSourcesGDB.FileGDBWorkspaceFactory as the ProgID value.

Jay

When you say utility, do you mean this is a standalone application or is it running inside ArcMap?

Hi Neil,

It's running as a standalone application. I have two separate entry points, and I think the problem might be that I am not binding to a license in the entry point from which I'm getting the failure. I have to solve another issue with Visual Studio crashing before I can test my theory.

Thanks for the response.

Hi All,

It turned out that all attempts to access ArcObjects were failing with the same error message. The cause was that I had forgotten to bind to a license in the standalone entry point. Adding a license binding fixed the problem.

Hi, I am getting the same problem for day, very annoying. I have added binding to Engine license at the start of my application, but still getting that error on every instance of x = new x. Please explain exactly what and where you made the fix.

thanks
