1、放置1個dxmapcontrol1在窗體上，設置align：=alclient
2、右鍵dxmapcontrol1控件，添加dxMapControl1ImageTileLayer1，設置Provider：=OpenStreetMapImageryDataProvider
3、右鍵dxmapcontrol1控件，添加dxMapControl1ItemLayer1,設置MapItems,添加2個 Custom Element
對象，並分別設置
dxMapControl1ItemLayer1CustomElement1.Text:='DevExpress Office'
dxMapControl1ItemLayer1CustomElement1.Location.Latitude:=34.1532
dxMapControl1ItemLayer1CustomElement1.Location.Longitude:=-118.2555
dxMapControl1ItemLayer1CustomElement2.Text:='Training Event'
dxMapControl1ItemLayer1CustomElement2.Location.Latitude:=50.3305
dxMapControl1ItemLayer1CustomElement2.Location.Longitude:=7.7300
4、右鍵dxMapControl1ItemLayer1,設置MapItems,添加1個 dxMapControl1ItemLayer1Polyline1對象，在GeoPoints屬性中添加兩個對象：
dxMapControlGeoPointCollection[0].Latitude:=34.1532
dxMapControlGeoPointCollection[0].Longitude:=-118.2555
dxMapControlGeoPointCollection[1].Latitude:=50.3305
dxMapControlGeoPointCollection[1].Longitude:=7.7300
5、設置屬性如圖所示：
6、程序運行界面如圖所示：
