I am trying to do snapping in arcMap at view option. I wrote the following code:

IPointSnapper pointSnapper; ISnappingEnvironment snappingEnv; ISnappingFeedback snappingFeedback; ISnappingResult snapResult;

pointSnapper = snappingEnv.PointSnapper; snapResult = pointSnapper.Snap(CurrentMouseCoordinate);

if (snapResult == null) return;

snappingFeedback.Update(snapResult, 0);

At this point, in the last line I got an exception: 'System.AccessViolationException'.

I have no clue why the exception has occured. Because snapResult is not null and contains snapResult.Description and snapResult.Location value. How can I resolve the problem?
