Hi,  Could someone tell me how to retrieve the Feature Class name for each layer in an MXD?  I tried this:  MapControlClass mapControl = new ESRI.ArcGIS.MapControl.MapControlClass(); mapControl.LoadMxFile(filename,null,null); ESRI.ArcGIS.Carto.IFeatureLayer layer = (ESRI.ArcGIS.Carto.IFeatureLayer)mapControl.get_Layer(1) as ESRI.ArcGIS.Carto.IFeatureLayer; But the Feature Class property is null? ESRI.ArcGIS.Carto.IFeatureLayer ptestLayer = mapcontl.FocusMap.get_Layer(1).Name; Thanks and Regards, Venkat ... View more

Thanks a lot... It was my answer.. can u help me in one more thing.... if i want to select feature on mousedown event---> first,i created a point,then i buffered it. now i need to check whether this point intersects with any other feature(i have a polyline shapefile also) If it does intersect then that line shud be selected.... I used spatial filter but it returns null value can u check the code please:   public void OnMouseDown(int button, int shift, int x, int y)         {            // # region attribute             activeView = m_mxDoc.ActiveView;             IPoint ppoint = new PointClass();                      ppoint = activeView.ScreenDisplay.DisplayTransformation.ToMapPoint(x, y);             ITopologicalOperator topologicalOperator = ppoint as ITopologicalOperator;             IGeometry gm = topologicalOperator.Buffer(1);             ISpatialFilter spatialFilter = new SpatialFilterClass();                                             IMap map = activeView.FocusMap;             pageLayout = (PageLayout)m_mxDoc.PageLayout;             l1 = map.get_Layer(0);             l2 = map.get_Layer(1);             if (l1.Name == "SSE_Access")             {                 layer_working = l1;             }             else if (l2.Name == "SSE_Access")             {                 layer_working = l2;             }             else             {                 layer_working = null;                 MessageBox.Show("Layer for attribute information does not exists");             }                         IFeatureLayer pfl = (IFeatureLayer)layer_working;             IFeatureClass featureClass = pfl.FeatureClass;             spatialFilter.GeometryField = featureClass.ShapeFieldName;             spatialFilter.Geometry = gm;             spatialFilter.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;             IFeatureCursor featureCursor1 = featureClass.Search(spatialFilter, true);             IFeature Feat1 = featureCursor1.NextFeature();             while (Feat1 != null)             {                 map.SelectFeature(layer_working, Feat1);                 Feat1 = featureCursor1.NextFeature();             } thanks in adv. hi, Please can you post the complete code what suppose to use .. where you getting error....

thank you for so much, actually i need it to be written in VBA-Arcobjects not in any other language. have you any idea how to do it in VBA-Arcobjects ? where can i find examples of similar kind of work? thank you regards Jamal Hi, please check below code...

Hi, Either you have to specify workspace if that one is available with you...or make it null. Something like this.... ESRI.ArcGIS.Geodatabase.IQueryFilter qf = new ESRI.ArcGIS.Geodatabase.QueryFilterClass();             qf.WhereClause = "Name='moscow'";             layer.FeatureClass.Select(qf, ESRI.ArcGIS.Geodatabase.esriSelectionType.esriSelectionTypeIDSet,                 ESRI.ArcGIS.Geodatabase.esriSelectionOption.esriSelectionOptionNormal, null); Thanks and Regards ...
