I have ArcGIS 9.3 installed and Microsoft Visual Studio 2010. I have existing file .gdb databases which I need to be able to read and write. Ideally this would be from a DLL which can be called from managed console applications. I have got as far as IWorkspaceFactory pWorkspaceFactory; IWorkspace2 m_pWorkspace; IFeatureWorkspace m_pFWorkspace; ... pWorkspaceFactory = new FileGDBWorkspaceFactoryClass(); if (pWorkspaceFactory.IsWorkspace(gdbPath)) { m_pWorkspace = (IWorkspace2)pWorkspaceFactory.OpenFromFile(gdbPath, 0); } the OpenFromFile method fails with "Exception from HRESULT: 0x80040228" There are other questions about this but they all relate to later versions and I can't see that 9.3 allows the solutions offered there. Any help gratefully received!
