”、“星期五”，这样，每到星期三和星期五的16:30，计算机就会自动为我们断开网络。
同样将“连接网络.bat”添加到计划任务中，让计算机在每周星期三和星期五的14:00自动执行“连接网络.bat”。
怎么样？连接或断开网络的事情再也不用我们自己去管了吧
（如果每天连接或断开网络的时间不同，则可以分别为每天设置计划任务）！







断开网络bat
@echo off
00:00 Rasdial %MyConnection% /disconnect
以上存为BAT文件。时间间改一下就可以了，分别是时和分









定时断开网络连接（BAT批处理文件设计参考）

提问：用批处理运行程序“xx.exe”30分钟后，断开网络连接。
      注意！要后台运行！在断开网络连接时不要回显！！
      我以前做了一个能后台运行，但是在断开网络连接时又弹出cmd对话框！

最佳答案

'vbs
GetObject("", "WScript.Shell").Run """" & "xx.exe" & """"
WSH.Sleep 1000 * 60 * 30
ChangeConnectionStatus False

Sub ChangeConnectionStatus(ByVal bEnable)
Const CONTROL_PANEL = &H3&
Const NET_CONNECTIONS = "网络连接"
Const CONNECTION = "本地连接"
Const ENABLE = "启用(&A)"
Const DISABLE = "停用(&B)"
Dim oShell
Dim oControlPanel, oControlItem
Dim oNetConnections, oConnectionItem, oConnection
Dim oVerbItem, oVerb
Dim bCurrentEnabled

Set oShell = CreateObject("Shell.Application")
Set oControlPanel = oShell.Namespace(CONTROL_PANEL)

For Each oControlItem in oControlPanel.Items
     If oControlItem.Name = NET_CONNECTIONS Then
      Set oNetConnections = oControlItem.GetFolder
      Exit For
     End If
Next

For Each oConnectionItem In oNetConnections.Items
  If oConnectionItem.Name = CONNECTION Then
   Set oConnection = oConnectionItem
   Exit For
  End If
Next

For Each oVerbItem In oConnection.Verbs
  If oVerbItem.Name = ENABLE Then
   bCurrentEnabled = False
   Set oVerb = oVerbItem
   Exit For 
  ElseIf oVerbItem.Name = DISABLE Then
   bCurrentEnabled = True
   Set oVerb = oVerbItem
   Exit For
  End If
Next

'If Not (bCurrentEnabled And bEnable) Then
If bCurrentEnabled <> bEnable Then
  oVerb.DoIt
  Do
   For Each oVerbItem In oConnection.Verbs
    If (bCurrentEnabled And (oVerbItem.Name = ENABLE)) Or _
     ((Not bCurrentEnabled) And (oVerbItem.Name = DISABLE)) Then _
     Exit Do
   Next
   WSH.Sleep 100
  Loop
End If

Set oVerb = Nothing: Set oVerbItem = Nothing
Set oConnection = Nothing: Set oConnectionItem = Nothing: Set oNetConnections = Nothing
Set oControlItem = Nothing: Set oControlPanel = Nothing
Set oShell = Nothing
End Sub

设计BAT批处理文件

　　首先我们用记事本建立一个.bat批处理文件,其内容如下:

　　@echo off

　　rem 定义循环间隔时间:

　　set secs=120

　　echo.

　　echo ============================================

　　echo == 此脚本用于计算机共享访问达到上限后使用 ==

　　echo ==运行脚本后会自动断开一些访问连接 ==

　　echo ==每%secs%秒种进行查询,并执行清除命令 ==

　　echo ============================================

　　echo.

nul || goto :error

　　:begin

　　set clear=0

　　echo.

　　for /f "tokens=1,2" %%i in ('net session ^| find ""') do (

nul 2>&1

　　 set clear=1

　　 echo %time:~0,8% 清除访问来源: %%i [%%j]
