I have a FileGeoDatabase with a AnnotationFeatureClass (within 3 AnnotationClasses) that I programmatically want to load to my map. First I load the FeatureClass in order to get some Informations and then while creating the AnnotationLayer an error occurs. I've used some code from the Esri-help, but what could be wrong?
Thanks for any suggestions!
Code:
Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.FileGDBWorkspaceFactory");
IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);
ws = workspaceFactory.OpenFromFile(pGdbSource.Dir + "\\" + pGdbSource.File, 0);
if (ws != null)
{
IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)ws;
IFeatureLayer featureLayer = new FeatureLayerClass();
string FCName = (pGdbSource.BrowseName != "") ? pGdbSource.BrowseName : pGdbSource.ItemName;
featureLayer.FeatureClass = featureWorkspace.OpenFeatureClass(FCName);
ILayer layer = (ILayer)featureLayer;
if ((featureLayer.FeatureClass.FeatureType == esriFeatureType.esriFTAnnotation) &&
(featureLayer is FeatureLayerClass))
{
// Get the GeometryDef from the feature class's shape field.
String shapeFieldName = featureLayer.FeatureClass.ShapeFieldName;
int shapeFieldIndex = featureLayer.FeatureClass.FindField(shapeFieldName);
IFields fields = featureLayer.FeatureClass.Fields;
IField shapeField = fields.get_Field(shapeFieldIndex);
IGeometryDef geometryDef = shapeField.GeometryDef;
IAnnotateLayerPropertiesCollection annotateLayerPropsCollection = (featureLayer as FeatureLayerClass).AnnotationProperties;
// Create a graphics layer scale object.
IGraphicsLayerScale graphicsLayerScale = new GraphicsLayerScaleClass();
try
{
graphicsLayerScale.ReferenceScale = mxDocument.ActiveView.FocusMap.MapScale;
}
catch (Exception ex) { graphicsLayerScale.ReferenceScale = 0.0; }
graphicsLayerScale.Units = mxDocument.ActiveView.FocusMap.MapUnits;
// Create the overposter properties for the standard label engine.
IOverposterProperties overposterProperties = new BasicOverposterPropertiesClass();
ISymbolCollection symbolCollection = new SymbolCollectionClass();
ISymbolCollection2 symbolCollection2 = (ISymbolCollection2)symbolCollection;
// Create the annotation layer factory.
IAnnotationLayerFactory annotationLayerFactory = new FDOGraphicsLayerFactoryClass();
IDataset pDataset = (featureLayer as FeatureLayerClass) as IDataset;
// Create the annotation feature class and an annotation layer for it.
IAnnotationLayer annotationLayer = annotationLayerFactory.CreateAnnotationLayer
(featureWorkspace, pDataset as IFeatureDataset, FCName,
geometryDef, null,
annotateLayerPropsCollection, graphicsLayerScale, symbolCollection, false,
false, false, true, overposterProperties, "configKeyword");
// Get the feature class from the feature layer.
featureLayer = (IFeatureLayer)annotationLayer;
