Get point from known points to a specific distance of a polyline arcgis

MonirRahman — Sun, 24 Jan 2016 09:23:51 GMT

I want to know the coordinates of a polyline from specific point and distance. I have attached image to clear the specification. say, I have a points B(2,3). I want to know the coordinates of A and B from 2 feet distance of B point. I have tried this:

public IPoint GetPointAtFrom(double distance, Coordinate givenCoordinate) { ArcGeometry.IPoint outletPoint = new ArcGeometry.PointClass(); ArcGeometry.ICurve curve = _polyline; curve.QueryPoint(ArcGeometry.esriSegmentExtension.esriExtendTangentAtFrom, distance, false, outletPoint); return new Point(outletPoint); }

but it gives from point or others.

any idea ?? I am using .net in arcgis 10.0 Thanks
