Hii I am new in GIS and java arcobjects. I have to call a click event on simple marker element on mapbean using java arc objects but i dont know how to do it. in my application I put approx 200 markers in mapbean now i have to select few of them approx 6 marker which is selected by user but i dont know how to select this particular marker I think if i am able to call click event on marker. then I would select it . No such thing as a SimpleMarkerElement. You have SimpleMarkerSymbol or MarkerElement. Neither of them have a click event. They have a hit test method, but not sure that is what you wanted. You can find marker elements by iterating over them and getting their name, assuming you set the name of each marker element. Or if you want to look at ISelection or ElementSelection. Also, the ActiveView has a getSelection method which returns a reference to ISelection. And, if you google, then you could have found this sample. http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/0048/00480000006z000000.htm Scroll down to the MoveGraphics and SelectElements methods for examples.

This is an interesting problem but you actually have two questions, it seems to me. 1. how to determine if the high point between two point is smooth or sharp(?) Which really depends on how you distinguish either in terms of your wave diffraction equation. Seems like a directional slope change problem, 2nd polynomial or running slope tool twice. 2. how to do this in ArcObjects. You really can't tackle this until you'v answered question 1.
