With ArcObjects 10.0 exists the IPolygon5-interface that holds only one member: IsEnvelope. It does not inherit all the members from IPolygon4. The IPolygon4-interface does inherit all the members from IPolygon, IPolygon2, IPolygon3. It is surely not a big deal to get the IPolygon5-interface of an object, but is nasty and unnecessary code. Is there any reason that the IPolygon5-interface does not inherit the members from IPolygon4 (despite the members of IPolycurve, ICurve and IGeometry)? ... View more

It is possible to define a certain layer as a mask for other layers in the context menu of the dataframe > Advanced drawing options, which is very usefull. No data will be displayed where the area is covered by the masking layer. Many times I would need it the other way round: Data should be displayed where the area is covered by the features of the masking layer. E.g. when I want a layer to display only data within a municipality I have to draw a polygon with the size of the whole extent and then subtract the area of the municipality. It would be easier just to be able to use the polygon of the municipality (which commonly already exists) and say "display everything inside the polygon". ... View more

Due to a bug in arcpy (removing a join between an SDE-featureclass and an ODBC-table fails) I was forced to make an add-in with C# in order to remove the join for many layers in a Mapdocument. After hourses of searching for a solution and messing around with RelationShipClass, I found a usefull example in the VBA-documentation (http://help.arcgis.com/en/sdk/10.0/vba_desktop/conceptualhelp/index.html#/How_to_remove_the_last_join_from_a_layer_or_table_in_ArcMap/00010000007s000000/). So, if someone is having the same problem, here is the solution: ESRI.ArcGIS.ArcMapUI.IMxDocument mxDocument = ArcMap.Application.Document as ESRI.ArcGIS.ArcMapUI.IMxDocument; // Dynamic Cast ESRI.ArcGIS.Carto.IActiveView actView = mxDocument.ActiveView; IMap focMap = actView.FocusMap; for (int i = 0; i < focMap.LayerCount; i++) {                 IFeatureLayer2 actFeatLyr = focMap.get_Layer(i) as IFeatureLayer2;                 ITable actLyr = focMap.get_Layer(i) as ITable;                 IDisplayTable actDispTable = actFeatLyr as IDisplayTable;                 IRelQueryTable actQueryTable = actDispTable.DisplayTable as IRelQueryTable;                 IDisplayRelationshipClass actDispRelClass = actFeatLyr as IDisplayRelationshipClass;                                 actDispRelClass.DisplayRelationshipClass(null, esriJoinType.esriLeftInnerJoin); } //Refreshing the view actView.Refresh(); //Refreshing the TOC ESRI.ArcGIS.ArcMapUI.IContentsView contentsView = mxDocument.CurrentContentsView;             contentsView.Refresh(null); ...
