I seem to get the intersecting points fine, my only issue is I cant seem  to identify the point on the polygon edge. Getting the first and last  point on the intersect point collection is not always the point on the  edge of the polygon.  That's what I'm still tryingto figure out.         It looks like it returns the points from the top to the bottom. I ran a test using the code below on a polygon and line, flashing each point in the geometry collection. The image below shows the direction the line was digitized by the arrows. The upper right intersection point was flashed first. Another question if someone knows the answer is why do I get so many  points when I only use the polygon boundary to intersect the polyline.  Shouldn�??t it just be two?         Is it a polygon with no internal holes? In the sample I ran, I used a donut polygon, which resulted in four intersections. If you look at the help for Boundary, you'll see that it will return all the rings of a polygon, not just the outside boundary.             Dim pLayer As ESRI.ArcGIS.Carto.ILayer2             Dim pLayer1 As ESRI.ArcGIS.Carto.ILayer2             Dim pFLayer As ESRI.ArcGIS.Carto.IFeatureLayer             Dim pFClass As ESRI.ArcGIS.Geodatabase.IFeatureClass             Dim pFCursor As ESRI.ArcGIS.Geodatabase.IFeatureCursor             Dim pFeature As ESRI.ArcGIS.Geodatabase.IFeature             Dim pPolygonGeometry As ESRI.ArcGIS.Geometry.IGeometry             Dim pLineGeometry As ESRI.ArcGIS.Geometry.IGeometry             Dim pTopoOp As ESRI.ArcGIS.Geometry.ITopologicalOperator             Dim pOverlapGeometryCollection As ESRI.ArcGIS.Geometry.IGeometryCollection             Dim pOverlapGeometry As ESRI.ArcGIS.Geometry.IGeometry             Dim pRgbColor As New ESRI.ArcGIS.Display.RgbColor             Using releaser As New ESRI.ArcGIS.ADF.ComReleaser                 releaser.ManageLifetime(pFCursor)                 pLayer = My.ArcMap.Document.FocusMap.Layer(0)                 pFLayer = New ESRI.ArcGIS.Carto.FeatureLayer                 pFLayer = pLayer                 pFClass = pFLayer.FeatureClass                 pFCursor = pFClass.Search(Nothing, False)                 pFeature = pFCursor.NextFeature                 pLineGeometry = pFeature.Shape                 pLayer1 = My.ArcMap.Document.FocusMap.Layer(1)                 pFLayer = New ESRI.ArcGIS.Carto.FeatureLayer                 pFLayer = pLayer1                 pFClass = pFLayer.FeatureClass                 pFCursor = pFClass.Search(Nothing, False)                 pFeature = pFCursor.NextFeature                 pPolygonGeometry = pFeature.Shape                 pTopoOp = pPolygonGeometry                 pOverlapGeometryCollection = pTopoOp.Intersect(pLineGeometry, ESRI.ArcGIS.Geometry.esriGeometryDimension.esriGeometry0Dimension)                 MsgBox(pOverlapGeometryCollection.GeometryCount)                 pRgbColor.Red = 255                 For j As Integer = 0 To pOverlapGeometryCollection.GeometryCount - 1                     pOverlapGeometry = pOverlapGeometryCollection.Geometry(j)                     FlashGeometry(pOverlapGeometry, pRgbColor, My.ArcMap.Document.ActiveView.ScreenDisplay, 500) ' this is an ArcGIS snippet                 Next            End Using [ATTACH=CONFIG]17019[/ATTACH] ...

Have you tried using the actual GUID of your tool instead? As I understand, the tool has to be on a tollbar or menu somewhere to use the ProgID (CTM.GIS.GISDesktop.CoordinateSelectorTool) UIDCls.Value =  "{" & yourClass.ClassId & "}" ... View more

The way I worked with multiple points from an intersection in one of my applications was to use IGeometryCollection, since the intersection returns a multipoint geometry instead of a point geometry. When I tested for overlapping polygons or lines sharing segments, I used IGeometry instead. This shows how I write the intersections to a point feature class. Dim pOverlapGeometryCollection As ESRI.ArcGIS.Geometry.IGeometryCollection = pTopoOp.Intersect(pInGeometry, ESRI.ArcGIS.Geometry.esriGeometryDimension.esriGeometry0Dimension) If pOverlapGeometryCollection IsNot Nothing Then     For j As Integer = 0 To pOverlapGeometryCollection.GeometryCount - 1         pOverlapGeometry = pOverlapGeometryCollection.Geometry(j)         pOverlapFeature = pOverlapBuffer         pOverlapFeature.Shape = pOverlapGeometry         pOverlapFeature.Value(pOverlapFeature.Fields.FindField(Field1)) = pFeature.OID         pOverlapFeature.Value(pOverlapFeature.Fields.FindField(Field2)) = pSelFeature.OID         pOverlapFCursor.InsertFeature(pOverlapBuffer)     Next End If ...

There is a bug (NIM061356) on using Python with ICalculator: ICalculator or ICalculatorUI2 do not offer a property where the parser (expression type) can be specified; VBScript is the default, so Python expressions error out. Their suggested workaround is as follows: Below is a workaround that compensates for the lack of being able to specify the parser in ICalculator.  It takes advantage of IGeoProcessor and the CalculateField_management geoprocessing tool.  The parser or expression_type argument of that tool can be used to specify Python as the parser. '(To test the below VBA code, create a UIButton in VBA and add the code inside the Click event handler of your new UIButton.  The second procedure, ReturnMessages(), is called into action by the first procedure towards the very end, but may not be necessary if you do not want to read the messages of the geoprocessing results.  Change the first parameter as needed to reflect the correct location of your input table.)

You should add some code to see what the messages in your results variable contain. Here's how I have it in one of my applications.
