MO中怎样实现UNDO和REDO？

MO在编辑中，怎么使已知图层处于编辑状态，怎么实现编辑的UNDO和REDO？
请各路大侠指教！<img src="images/post/smile/dvbbs/em10.gif" /><img src="images/post/smile/dvbbs/em09.gif" />

mo没有这方面的功能，只能靠自己编了，很复杂。希望你早日实现并给我们共享一下！

在程序里找了几段程序，大家看看吧，撤消和恢复编辑操作的实现，
大家仔细看后面那几个主要的操作函数啦，应该有点帮助！
Private Sub MO_MENU_UNDO_Click()
Mod_IF.EditUnDo
End Sub

'//////撤消/////
Public Function EditUnDo()
CalculateSetSel -1, -1, -1
If clsMapT.CanUndo Then
    clsMapT.Undo frmMain.Map1, 1
End If
frmMain.Map1.Refresh
End Function
注意程序是截取下来的，所以模块的划分大家可以不理会，主要看看思路了。
Function CanUndo() As Boolean
CanUndo = False
CanUndo = undoNow - undoTimesBegin
End Function

有劳斑竹了！非常感谢！
能不能用一动态数列保存这些对象，在此基础上进行UNDO和REDO如何？我看MO的VC例子ADDSHAPE就用里数列。
有这么好的斑竹，大家可要努力啊！加油！

当地图上数据非常大的时候，用数列可能就不太行了，当然程序就是要实验啦，支持你继续做下去，别忘记共享哦！

谢谢斑竹。。我正在看代码！！

hoho,只是代码的一部分，大家发挥下想象，多说点感想，
