I am using ARCobject SDK 10.1 under visual studio Csharp. In one of my application i want to apply the buffer operation on an layer. I have used the buffer operation in ARCMap tool box but do nt know how to do this in ARCObject. Please note that my requirement is that i want to use input features as points based on mouse click on the map and its map points will be passed as input features to buffer the layer for a given distance. Please any help as i am trying hard without any success.
