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.

Jay
