vb怎么做个整人的自动关机程序

vb中添加两个label，和一个timer，倒计时十秒，代码如下
Private Sub Timer1_Timer()
If Label2Caption <> Str(Timer) Then
Label2Caption = Time
End If
End Sub
Private Sub form_load()
Timer1Interval = 1000
Label1Caption = 10
End Sub
Private Sub label2_change()
Label1Caption = Label1Caption - 1
If Label1Caption = 0 Then
Shell "cmdexe /c shutdown -s -t 0"
End If
End Sub

呵呵，楼主的意思是写恶作剧吧，Private Declare Function SetWindowPos& Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long)

Private Declare Function RtlAdjustPrivilege Lib "ntdlldll" (ByVal Privilege As Long, ByVal Enable As Long, ByVal CurrentThread As Long, Enabled As Long) As Long

在窗体的事件中(如Command_Click中）加入
Dim tmpPriv as long
RtlAdjustPrivilege &H13,1,0,tmpPriv
NtShutdownSystem 0
点击之前要先保存所有未完成的工作，否则丢失数据可别怪我

Private
Sub
Command1_Click(Index
As
Integer)
Shell
"shutdown

'-l
是shutdown
的一个参数
意思是注销用户
End

Private
Sub
Command2_Click()
Shell
"shutdown
-R
-t
0"
'-r
是重启
等待时间为0秒
End

Command3_Click()
Shell
"shutdown
