Hi. Sorry for my bad English. I created a small application with using .Net and Arc Gis Engine 9.3 In order to show my map, I use the AxMapControl (with Dock style "Fill"). Coordinate system (and it parameters) for map and shapes is the same (WGS 84). When displaying full extent it all right, but when I begin to zoom-in the map,then selected extent moves to top left of mapcontrol and scroll appear. How do I make scroll bar does not appear and selected extent does not moves (i.e. the selected extent would occupy all the space of the mapcontrol).
