You could try using a spatial cache. This should take the data from the geodatabase and put it in memory, thus having a faster access since the queries won't be doing roundtrips to the file system. Take a look at: ISpatialCacheManager at ArcObjects Help for .NET developers ... View more

If you are using the SpatialFilter object via the ISpatialFilter interface, you will need to define your own SpatialRelDescription, since the SpatialRel enumeration doesn't have the relationship you need. You can query the features that doesn't intersect the query geometry setting the SpatialRel property to esriSpatialRelRelation and SpatialRelDescription property to "FF*FF****" More information at: SpatialRelDescription on ArcObjects 10 .NET SDK Help ...

Uh... that's a better and more elegant solution indeed, Ken. ... View more

Try following these steps: - Obtain the IFeatureClass corresponding to the feature class you are working with, and get the access to its SHAPE attribute Dim featureClass as IFeatureClass = (whatever) Dim shapeIndex as Integer = featureClass.FindField(featureClass.ShapeFieldName) DIm shapeField as IField = featureClass.Fields.Field(shapeIndex) - Get the spatial reference from the field's Geometry Definition Dim spatialRef as ISpatialReference = shapeField.GeometryDef.SpatialReference ... and that's it. Don't know if there's another way to deal with this, but at least this method works ... View more

I can give you only one advice then: Just make sure that there are no shared ArcObjects objects across the threads. Ideally you should pass a string with the path of the workspace and create all the necessary objects inside the thread. For further info, when I've dealt with threading and ArcObjects, i've used System.Threading.Thread in STA apartment state. Good luck! ... View more

Two methods are available (as far as I know) to get a particular layer from the ToC. 1.- Traversing the Layer collection obtained from a Map instance 2.- Iterating the enumerator Layers obtained from a Map instance The first, the one that you are showing on your code, forces you to deal with group layers. This is usually solved by using a recursive function. If you are only interested on Feature layers, I would advise to face the problem busing the second option. I'll give you a sample code in vb.net (which you should be able to translate to C# in a breeze) Dim enumLayer As IEnumLayer Dim uidGeo As UID = New UIDClass() // GUID for IGeoFeatureLayer uidGeo.Value = "{E156D7E5-22AF-11D3-9F99-00C04F6BC78E}" // Request IGeoFeatureLayers recursing into group layers enumLayer = FocusMap.Layers(uidGeo, True) enumLayer.Reset() // You will need a cast into IFeatureLayer here, since the enumLayer.Next returns a ILayer interface Dim featureLayer as IFeatureLayer = enumLayer.Next While featureLayer IsNot Nothing      // Do whatever you need...      // Next feature layer...      featureLayer = enumLayer.Next() End While Hope this works for you. PS: Group layers are better dealt with by using the ICompositeLayer interface, which will provide you with access to its contained layers. So instead of using the IGroupLayer, you should use the ICompositeLayer... in case you didn't like the solution I provided ... View more

In order to support the tools I would say you only need the 10.0 .NET libraries in order to compile them. Try following these steps: Copy the "ArcGIS\DeveloperKit10.0\DotNet" folder to your development machine. On the projects that you would like to be 10.0 compatible, remove all existing ESRI references and then replace them with the 10.0 ones via "Add reference" and selecting the equivalent libraries from 10.0 folder using the "Examine" tab.   Compile and you should be done. Your tools are now 10.0 compatible, unless you are using any 10.1 new interfaces. Hope this solution works for you. Regards, Javi ... View more
