2、Events2_OnMouseDownEvente,stringstrOperType1){switch(strOperType1){//用鼠标拖曳确定地图显示范围case"LKXS":{axMapControl1.MousePointer=esriControlsMousePointer.esriPointerCrosshair;//改变鼠标样式axMapControl1.Extent=axMapControl1.TrackRectangle();//将地图控件显示范围设置为当前拖曳的矩形区域axMapControl1.ActiveView.PartialRefresh(esriViewD

3、rawPhase.esriViewGeography,null,null);//刷新地图break;}//移动地图、地图漫游case"DTMY":{axMapControl1.Pan();break;}//绘制点case"HZD":{IMappMap;IActiveViewpActiveView;pMap=axMapControl1.Map;pActiveView=pMapasIActiveView;//新建点对象IPointpPt;pPt=newPointClass();pPt.PutCoords(e.mapX,e.mapY);//产生一个Market元素IMarkerElementpMa
