how to get point within a distance along a polyline given inPoint?

[HailiangShen]

Dear All,
I need to finish the following task: given a point (inPoint) within a polyline (pl), find the point which is:

- within the polyline pl
- distance along the polyline pl between inPoint and the point to-be-find is 250 m

Is there any way to do it with ArcObject?
Thanks for any suggestions,
Hailiang

Hi Hailiang

Use ICurve.QueryPointAndDistance to find the distance of your inPoint along the curve.
Then use ICurve.QueryPoint and give the distance from the first method + 250 m

Have fun

Thanks Mody for your suggestion, problem solved using QueryPointAndDistance and QueryPoint methods.
