I don't usually need to deal with geometries too often in ArcObjects, but this is giving me quite a hard time. I can get a IFeature object from my SDE. I can access the attributes fields just fine and pass them as needed. The problem is, when I try to access the IFeature.Shape property, I get the following error. Error HRESULT E_FAIL has been returned from a call to a COM component. stacktrace at ESRI.ArcGIS.Geodatabase.IFeature.get_Shape() This is a code snippet below. Type sde_type = Type.GetTypeFromProgID("esriDataSourcesGDB.SdeWorkspaceFactory"); //IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)new SdeWorkspaceFactoryClass(); IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(sde_type); IWorkspace workSpace = workspaceFactory.Open(propertySet, 0); IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workSpace; #endregion IFeatureClass featureClass = featureWorkspace.OpenFeatureClass("sde.LA_Parcels"); // prepare the query filter IQueryFilter qf = new QueryFilterClass(); qf.SubFields = "AIN"; qf.WhereClause = "AIN = '" + ain + "'"; IFeatureCursor fc = featureClass.Search(qf, true); IFeature feat = fc.NextFeature(); string s_ain = "NOT FOUND"; if (feat != null) { int field = feat.Fields.FindField("AIN"); s_ain = feat.get_Value(field) as string; // grab some more field data ... IGeometry fgeom = null; try {   fgeom = feat.Shape; // error gets thrown here } catch (Exception e) {   throw new Exception(String.Format("ParcelLocationData Geometry from Shape Error: {0}", e.Message), e); } } I had read on a blog that it was good practice when creating ArcObjects objects on server to not use "new", but use Activator.CreateInstance, so I switched that up as it came up in my search on the COM error, but still nothing works. I can view this data in ArcMap just fine, it works on MapServices that we have. I have other C# dll's using ArcObjects running on this server just fine for sewer tracing, none of which actually access the IFeature.Shape property though. Is there a step I am missing to try and do this? My goal here is to use the IFeature.Shape as a basis for some spatial queries on other features. Something like this IArea area = (IArea)fgeom; spatialFilter.Geometry = area.Centroid Thanks in advance, and I'm sorry if this is something simple I am missing. ... View more

I am trying to set the InfoWindow title via my ItemRenderer that I am assigning to a FeatureLayer. I can set the title from the map.infoWindow.label, but my ItemRenderer doesn't have access to the map and the title will vary among FeatureLayers. All the samples are still using mx comps with inline ItemRenderers. Spark containers don't have a label field and mine are set up from ClassFactory in AS3. I tried setting the ItemRenderer label (label="{data.Type}"), but that doesn't seem to get reflected in the InfoWindow. Do I need to extend the InfoWindow to add this or is there a simpler method of setting the InfoWindow title? For example, here is my ItemRenderer that is assigned to one Featurelayer. Can I set the InfoWindow title from this ItemRenderer? <?xml version="1.0" encoding="utf-8"?> <s:ItemRenderer xmlns:fx="http://ns.adobe.com/mxml/2009"     xmlns:s="library://ns.adobe.com/flex/spark"     autoDrawBackground="false"     label="{data.Type}"> <fx:Script>   <![CDATA[    override public function set data(value:Object):void    {     super.data = value;     // TODO - calc lat/longs, parse img data     lblCost.text = stringValue(value.COSTINFO)     lblLease.text = stringValue(value.LEASEINFO);     lblLease2.text = stringValue(value.LEASEINFO2);     lblMeter.text = stringValue(value.METERINFO);     lblElec.text = stringValue(value.ELECTRICAL);    }       private function stringValue(value:String):String    {     return (value.length > 1) ? value : "None";    }   ]]> </fx:Script> <s:Group id="grpMain"     width="100%"     height="100%">   <s:layout>    <s:HorizontalLayout gap="8"         paddingBottom="5"         paddingLeft="5"         paddingRight="5"         paddingTop="5" />   </s:layout>   <s:Group id="fieldNames">    <s:layout>     <s:VerticalLayout gap="2" />    </s:layout>    <s:Label text="Lat:" />    <s:Label text="Long:" />    <s:Label text="Image: " />    <s:Label text="Cost Info:" />    <s:Label text="Lease Info:" />    <s:Label text="More Lease Info:" />    <s:Label text="Meter Info:" />    <s:Label text="Electrical Info:" />   </s:Group>   <s:Group id="fieldValues">    <s:layout>     <s:VerticalLayout gap="2" />    </s:layout>    <s:Label id="lblLat" />    <s:Label id="lblLong" />    <s:Label id="lblImage" />    <s:Label id="lblCost" />    <s:Label id="lblLease" />    <s:Label id="lblLease2" />    <s:Label id="lblMeter" />    <s:Label id="lblElec" />   </s:Group> </s:Group> </s:ItemRenderer> ...
