I see it now:         ESRI.ArcGIS.Geoprocessing.GeoProcessor gpUnManaged = new ESRI.ArcGIS.Geoprocessing.GeoProcessor(); gpUnManaged.Execute(name, params, trackCancel); VS         ESRI.ArcGIS.Geoprocessor.Geoprocessor gpManaged = new ESRI.ArcGIS.Geoprocessor.Geoprocessor(); gpManaged.Execute(tool,trackCancel); Details, details... Thanks a lot! ... View more

Of course, you are right ! I was confused by the different SDK's available. Downloaded ArcObjects SDK instead, and everything is back to normal. Thanks a lot! -Ola ... View more

You should release the feature objects you're using inside the loop in each loop iteration.  The ones I see are fSource, fTargetNew and f (at least it looks like f is a feature object).  Call ReleaseComObject on these feature objects inside the loop just as soon as you're done with them just like you do for cursor objects. I have done that, but unfortunately the problem is still there. I have a feeling that there is a fundamental error here that I have overlooked... ... View more

Can you provide details on how many features get added or updated before you get this error? Also are you using recycling cursor or non-recycling cursor? Try releasing cursor after 40,000 or 50,000 iterations and see if that makes any difference. Cheers!! Sumit Thanks for answering. I have tried that in other situations, and it helped. But not here. Only a few hundred features are inserted before the crash. I will reexamine cursor usage. See also example code in above answer. ... View more

Can you post the code for import features? Also, Did you monitor the memory usage in taskmgr while running insert features? Memory usage seem to be normal, with plenty left. It is unpractical to post the entire routine (many layers), but to give an idea of what is going on, here is the main operations: // // Initiate: IFeatureclass fcSource = .. IFeatureClass fcTarget = ... IWorspaceEdit wsTarget = ... List sourceIdList = ... // // Start transaction: wsTarget.StartEditing(false); wsTarget.StartEditOperation(); // // Do import: foreach(int sourceOid in sourceIdList) { IFeature fSource = fcSource.GetFeature(sourceOid); ... int a = fSource.get_value(..); int b = fSource.get_value(...); // // Examine values in target fc if necessary: if(boundsHaveChanged) {          String whereRestriction = "(a>"+a.ToString() + ") and (b<"+b.ToString()+")";          IQueryFilter qf = new QueryFilterClass();          qf.WhereClause = whereRestriction;                                   qf.AddField(fieldName);          IFeatureCursor fcur = fl.FeatureClass.Search(qf, false);          IDataStatistics dstat = new DataStatisticsClass();          dstat.Cursor = (ICursor)fcur;          dstat.Field = fieldName;          IStatisticsResults res = dstat.Statistics;          int maxFound = System.Convert.ToInt32(res.Maximum);          ...          Marshal.ReleaseComObject(fcur);                  Marshal.ReleaseComObject(dstat); } IFeature fTargetNew = fcTarget.CreateFeature(); IPoint p = new PointClass(); ... fTargetNew.Shape = p; ...  fTargetNew.set_value(i, f.get_value(j) ); ... fTargetNew.Store(); } wsTarget.StopEditOperation(); wsTarget.StopEditing(true); ... ...

It would look something like this: Dim pFLayer As IFeatureLayer = pMap.Layer(0) Dim pDefQ As IFeatureLayerDefinition pDefQ = pFLayer pDefQ.DefinitionExpression = "OBJECTID = " & 11420  'I just set this for testing an Integer value 'altered to query a string field pDefQ.DefinitionExpression = "SomeStringField = '" & someStringValue & "'"  That's it, thanks a lot! As often before, the solution is quite simple as long as you can find the right interfaces and examples. Which reminds me that the current help system, connected to the VisualStudio, usually answers everything I am NOT looking for... ... View more

So you are invoking a DefinitionQuery on a featureLayer? The default behavior seems to be that the selected feature should not show if included in the definition query filter.  Perhaps it is something specific with your code that is producing the behavior you are seeing. Post up the code you have so far. I guess a queryfilter in the featurelayer would do the trick, but cannot find out how... The examples I find are related to the ArcIMS API, and I cant find similar methods here... Could you give me a hint where to start? ... View more

The layer itself is set to visible, but I am trying to hide individual features within, based on some attribute values, and even hide them the from ArcMap's selection tool. Ola, Are you saying that when you toggle the layer's visibility off, you can still see the selected features? If so, then it might be that you need to do a full refresh on the ActiveView: 'This line would refresh the selection pDoc.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGeography, Nothing, Nothing) 'add this line to fully refresh the view pDoc.ActiveView.Refresh() ...

My guess is that you end up rewriting everything, in order to take advantage of better project management and structures... ... View more
