怎样用VB做一个关机程序？

[benniao2]

我想用VB做一个按钮，在开机时就启动，单击就能关机，请各位高手帮帮忙！！！

Shell应该可以

开机时就记动要写注册表
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

关机用一个API搞定
exitwindows

如何关闭／重新启动计算机?

　

16位Windows用ExitWindows() API函数，而32位Windows则用ExitWindowsEx().32位版本比16位版本多了更多的控制及选项，包括注销及关机。

Declare Function ExitWindows Lib "user" (ByVal uFlags As Long, ByVal _
dwReserved As integer) As integer
Const EW_REBOOTSYSTEM = &H43
Const EW_RESTARTWINDOWS = &H42

Sub Command1_Click()

Dim iAns As Integer
Dim rVal As Integer
Dim iButtonType as Integer

iButtonType = 4 + 32 ' vbYesNo + vbQuestion

' Ask if the user is sure they want to exit.
iAns = MsgBox("Are you sure you want to exit windows?", iButtonType, _
"Exit Windows")
If iAns = 6 Then ' Yes pressed
' Call the exit function to Reboot.
rVal = ExitWindows(EW_REBOOTSYSTEM, 0)
End If

End Sub

***** 32位的例子 *****
In a project with 1 commandbutton, place the following code:
Private Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, _
ByVal dwReserved As Long) As Long
Private Const EWX_LOGOFF = 0
Private Const EWX_SHUTDOWN = 1
Private Const EWX_REBOOT = 2
Private Const EWX_FORCE = 4

Private Sub Command1_Click()

Dim iAns As Integer
Dim rVal As Long

' Ask if the user is sure they want to exit.
iAns = MsgBox("Are you sure you want to exit windows?", vbQuestion Or _
vbYesNo, "Exit Windows")
If iAns = vbYes Then
rVal = ExitWindowsEx(EWX_SHUTDOWN, 0&)
End If

End Sub

ExitWindowsEx在98下面很容易实现
