Here is the code that I used to get it to work. Chris private void TextBlock_MouseEnter(object sender, MouseEventArgs e)         {                         QueryResultData HiLight = (QueryResultData)(sender as FrameworkElement).DataContext;                         Graphic g = getGraphic(HiLight);             g.Symbol = SearchSelectedSymbol;             if (g != null)             {                 g.Select();                 g.SetZIndex(1);             }         }         private void TextBlock_MouseLeave(object sender, MouseEventArgs e)         {             QueryResultData HiLight = (QueryResultData)(sender as FrameworkElement).DataContext;             Graphic g = getGraphic(HiLight);             g.Symbol = SearchPictureSymbol;             if (g != null)             {                 g.Select();                 g.SetZIndex(0);             }         }                private Graphic getGraphic(QueryResultData HiLight)         {             GraphicsLayer layer = MyMap.Layers["MyGraphicsLayer"] as GraphicsLayer;             if (HiLight != null && layer != null)             {                              foreach (Graphic g in layer.Graphics)                 {                                         if (g.Geometry == HiLight.SHAPE)                     {                         return g;                     }                 }             }             return null;         }         ...

Thanks Morten, That is exactly what I want. Chris ... View more

Another way to do this is to prepare a theissen polygon layer first, put that in your service but don't draw it, and then you will only need one call to get the closest polygon ID with a simple query.  You can make a theissen polygon directly if you have input points.  Otherwise, you will need to use the feature to points command in Arcmap to turn the polygon vertices into points, then use the create theissen polygons with the all fields option.  This will put a polygon around each point with the id of the polygon attached to each point.  Next dissolve on the input fid to make one theissen polygon per input polygon (this is not really necessary, but will give a more generalized data set).  Now you a data layer that allows you to click on the map and bring back the id of the closest polygon.

I figured out how to extend the polylines within the polygon using IConstructCurve.ConstructExtended.  Now I just have to figure out how to trim the polylines outside of the polygon. Chris ... View more

Duncan, Thanks for the help.  I am using C#, so it is a bit different from VB.  I have to use the ICursor, but the rest was like yours. ICursor pCursor; pSelectionSet.Search(null, false, out pCursor); IFeatureCursor pFeatureCursor = (IFeatureCursor)pCursor; IFeature pFeature = pFeatureCursor.NextFeature(); inpolyline = (IPolyline)pFeature.Shape; ...

Here is the website with the arcmap command guids.  http://resources.esri.com/help/9.3/ArcGISDesktop/dotnet/858a508c-b771-467c-81e6-c6aa72d88f9c.htm The guids are only for the tools and buttons.  You will have to create a command, and use the geoprocessor function to integrate the "make xy event layer" into a tool that has a guid.  Check out this link: http://edndoc.esri.com/arcobjects/9.2/NET/0bf044f6-dbcd-4d04-836e-3b5e47204818.htm   (this is 9.2, they probably have it in 9.3) Chris ...
