关于切断网络的问题。
请问如何切断网络。
就像防火墙一样，点一点击“断网”就可以切断网络。
请教大家。

VB：如何启用/禁用本地连接
其实没什么说的，无非就是先找到“网络连接”这个虚拟文件夹，然后找到要控制的本地连接对应的folderitem，然后枚举verb，找到需要的verb后，调用verb的DoIt方法，在winxp sp2 ，vb6 sp6下测试通过，代码如下：
Option Explicit
'首先引用Microsoft Shell Controls And Automation
Private Function ExcNetLinkMenu(ByVal AdapterName As String, ByVal MenuName As String) As Boolean
On Error Resume Next
Dim mShell As New Shell32.Shell
Dim NetConnection As Shell32.Folder
Dim FolderItem As Shell32.FolderItem
Dim NetConnectionItem As ShellFolderItem
Dim verb As Shell32.FolderItemVerb
Set NetConnection = mShell.NameSpace(49) '这个49是我找出来的，有了它就可以避免遍历控制面板
If ObjPtr(NetConnection) = 0 Then
ExcNetLinkMenu = False
GoTo exitfunction
End If
Dim flag As Boolean
flag = False
For Each FolderItem In NetConnection.Items
If FolderItem.Name = AdapterName Then
Set NetConnectionItem = FolderItem
flag = True
Exit For
End If
Next
If flag = False Then
ExcNetLinkMenu = False
GoTo exitfunction
End If
For Each verb In NetConnectionItem.Verbs
If verb.Name = MenuName Then
flag = True
verb.DoIt
ExcNetLinkMenu = True
GoTo exitfunction
End If
Next
If flag = False Then
ExcNetLinkMenu = False
GoTo exitfunction
End If
exitfunction:
Set mShell = Nothing
Set NetConnection = Nothing
Set FolderItem = Nothing
Set NetConnectionItem = Nothing
Set verb = Nothing
End Function
Private Sub Command1_Click()
Dim flag As Boolean
'把 本地连接 2 换成你要控制的本地连接的名字
flag = ExcNetLinkMenu( "本地连接 2 ", "停用(&B) ") '这个在2000下对应的是禁用,具体是什么，点右键,自己看吧
End Sub
Private Sub Command2_Click()
'把 本地连接 2 换成你要控制的本地连接的名字
Dim flag As Boolean
flag = ExcNetLinkMenu( "本地连接 2 ", "启用(&A) ")
End Sub

用wscript.shell改一下注册表相关键值
