excel里用vba实现开始计时 暂停计时 结束计时这三种功能 暂停的同时可以开始另一个计时 大侠们帮帮我吧

参考技术A Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Range("B1") = "开始"
Range("B2") = "暂停"
Range("B3") = "继续"
Range("B4") = "停止"
If Selection.Count > 1 Then End
If Target = "" Then End
Range("A1").NumberFormatLocal = "h:mm:ss"
Range("A2").NumberFormatLocal = "h:mm:ss"
Range("C1").NumberFormatLocal = "h:mm:ss"
Range("C2").NumberFormatLocal = "h:mm:ss"
nm = Target.Value
If nm = "开始" Then
Range("A1") = ""
Range("A2") = ""
Range("C1") = Now
Range("C2") = ""
Call JS(1)
Else
If nm = "停止" Then
Range("C1") = ""
Range("C2") = ""
Else
If nm = "暂停" Then
Range("C1") = ""
Range("C2") = Now
Call JS(2)

If nm = "继续" Then

Sub Disp1()

用java编一个简单的倒计时表

他倒计时1分钟，但是显示的是几小时几分几秒 界面中有三部分 一个开始一个暂停。按暂停停止 安开始又继续 麻烦高手们了。。。谢谢 要全面的。。

先不要关闭问题，给我点时间我编出来，我也想断炼一下。
代码如下：
我这程序有点问题 ，这倒计时你讲的功能都有了，但那个暂停按钮有问题，只能用两次，我怎么也找不出原因， 我想是多线程方面的问题吧，按两下那暂停按钮就失去作用了。
