新建一工程，放两个MapX控件：Map1（主），Map2（导航），放三个按钮用来放大、缩小和漫游：

CmdZoomIn,CmdZoomOut,CmdPan

'本程序演示MapX的“鹰眼”窗口
'采用MapX的Feature方式实现
Dim m_TempLayer As Layer '导航图上临时图层
Dim m_Fea As MapXLib.Feature '导航图上反映主地图窗口位置的Feature
Dim bDown As Boolean '鼠标在导航图上按下的标志

Private Sub CmdPan_Click()
Map1.CurrentTool = miPanTool
End Sub

Private Sub CmdZoomIn_Click()
Map1.CurrentTool = miZoomInTool
End Sub

Private Sub CmdZoomOut_Click()
Map1.CurrentTool = miZoomOutTool
End Sub

Private Sub Form_Load()
''给Map2增加临时图层
Set m_TempLayer = Map2.Layers.CreateLayer(wewew)
End Sub

Private Sub Form_Unload(Cancel As Integer)
Set m_Fea = Nothing
Set m_TempLayer = Nothing
End Sub

''根据map1的Bounds在Map2上绘制矩形
Private Sub Map1_MapViewChanged()
Dim tempFea As MapXLib.Feature
Dim tempPnts As MapXLib.Points
Dim tempStyle As MapXLib.Style
