Add line feature to polyline feature class - VB/VBA

WoodyFields — Fri, 15 Apr 2011 02:29:35 GMT

I am pulling my hair out on this one. I have a polyline feature class and two points in a point shapefile. I have the points set as IPoints in code. I have the polyline set as an IPolyline. I defined an IPath using the two IPoints as from and to points. I have tried using the .AddGeometry function to add the two points as a path to my existing polyline layer with no luck. Maybe I am not setting the feature class correctly to accept the geometry. Maybe there is a better way? Can someone please help me?

Thanks in advance!

You can only add high level geometries to feature classes. A path isn't a high level geometry. A line feature class can only store polyline geometries. You need to be creating a new polyline geometry and using that to set the geometry of a new feature.

Dim polyline As IPolyline = new Polyline
polyline.FromPoint = onePoint
polyline.ToPoint = otherPoint
Dim feature As IFeature = featureClass.CreateFeature
feature.Shape = polyline
feature.Store

Thanks Neil! That did the trick and fits into my code so much nicer. Any way I can give you "he is awesome points" for this?
