Is this code correct? FP = AcL.StartPoint : SP = AcL.EndPoint Dim dx As Double = SP.X - FP.X Dim dy As Double = SP.Y - FP.Y Dim len As Double = Math.Sqrt((dx * dx) + (dy * dy))

If its just for a line, you can simply use the Length property. Or the Delta property if you want the length as a vector.
