ArcEngine license problem (Edit session)

ThomasWaenke — Tue, 28 May 2013 15:21:39 GMT

I have a problem to start an edit session in a Engine standalone application. To make sure that the problem is not within my own code I created a new MapControlApplication with the VS2010 wizard and added the code to start an edit session.

        private void StartEditing()
        {
            IMap map = axMapControl1.Map;

            //If an edit session has already been started, exit.
            if (m_engineEditor.EditState != esriEngineEditState.esriEngineStateNotEditing)
                return;

            //Start editing the workspace of the first feature layer found.
            for (int layerCounter = 0; layerCounter <= map.LayerCount - 1; layerCounter++)
            {
                ILayer currentLayer = map.get_Layer(layerCounter);
                if (currentLayer is IFeatureLayer)
                {
                    IFeatureLayer featureLayer = currentLayer as IFeatureLayer;
                    IDataset dataset = featureLayer.FeatureClass as IDataset;
                    IWorkspace workspace = dataset.Workspace;
                    m_engineEditor.StartEditing(workspace, map);
                    ((IEngineEditLayers)m_engineEditor).SetTargetLayer(featureLayer, 0);
                    break;
                }
            }
        }

This code throws a COM exception HRESULT: 0x8004021F and the Error code is -2147220961. I found in the help that this means that the license is not sufficient to edit this type of data (FDO_E_NO_EDIT_LISENCE).
I have an EDN subscription and I have ArcEngine and ArcGIS for Desktop Standard installed on my computer. The GDB that the map uses is a file geodatabase and contains some featureclasses and other tables that are connected with relationship classes.

I tried all possible license settings in the LicenseControl but the error is always the same. I also copied the contents to a personal GDB - same error.

There is no problem when the map is opened in ArcMap.

What could be the problem?

It seems that ArcEngine cannot create an edit session when the GDB contains featureclasses that have attributetables connected through relationshipclasses. When I remove the relationships from the GDB the edit session can be created.

I think you need to load up the geodatabase update extension to work with relationship classes in engine.
