Windows 95 重新開機十分簡單,只要呼叫 ExitWindowsEx API 函數就可以了, 例如: API 宣告式: Private Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long , _
ByVal dwReserved As Long) As Long Private Enum HowExitConst
EWX_LOGOFF = 0 ' 登出
EWX_REBOOT = 2 ' 重開機
EWX_SHUTDOWN = 1 ' 關機
EWX_FORCE = 4 ' 強制關機
End Enum 呼叫敘述: Call ExitWindowsEx(how, 0)
' how 等於 EWX_LOGOFF 、 EWX_REBOOT 、EWX_SHUTDOWN 、 或EWX_FORCE但是這個方法並不能對 NT 關機或重新開機, 原因是 NT 比較著重安全性(Security),
而為了讓 NT 關機或重新開機, 則必須在呼叫 ExitWindowsEx 之前, 呼叫
AdjustToken 副程式就對了。AdjustToken 副程式的細節如下:1. API 的宣告: Enum HowExitConst
EWX_FORCE = 4 ' 強制關機
EWX_LOGOFF = 0 ' 登出
EWX_REBOOT = 2 ' 重開機
EWX_SHUTDOWN = 1 ' 關機
End Enum Const TOKEN_ADJUST_PRIVILEGES = &H20

Private Declare Function OpenProcessToken Lib "advapi32.dll" _
(ByVal ProcessHandle As Long, ByVal DesiredAccess As Long, _

Dim hdlTokenHandle As Long
Dim tmpLuid As LUID
Dim tkp As TOKEN_PRIVILEGES
Dim tkpNewButIgnored As TOKEN_PRIVILEGES
Dim lBufferNeeded As Long

AdjustTokenPrivileges hdlTokenHandle, False, tkp, Len(tkpNewButIgnored), _
tkpNewButIgnored, lBufferNeeded
End Sub3. 呼叫的範例: AdjustToken
Call ExitWindowsEx(how, 0)
'how 等於 EWX_LOGOFF 、 EWX_REBOOT 、 EWX_SHUTDOWN、 或EWX_FORCE在 Windows 95 底下呼叫了 AdjustToken 也沒關係,因為 Windows 95 並不會
理會安全性的設定。
在95/98下其實還可以呼叫

ExitWindowsEx VB声明
Declare Function ExitWindowsEx Lib "user32" Alias "ExitWindowsEx" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long
说明
退出windows,并用特定的选项重新启动
返回值
Long,非零表示成功,零表示失败。会设置GetLastError
参数表
参数 类型及说明
uFlags Long,指定下述一个或多个标志(用OR运算符合并到一起)
EWX_FORCE 强迫中止没有响应的进程
EWX_LOGOFF 中止进程,然后注销
EWX_SHUTDOWN 关掉系统电源(如果可能的话,ATX电源就可以)
EWX_REBOOT 重新引导系统
EWX_SHUTDOWN 关闭系统
dwReserved Long,保留,设为零
注解
这个函数调用后会立刻返回,系统关闭过程是在后台进行的。注意先中止自己的应用程序,使关闭过程更显平顺。当然,您的进程必须有足够的优先权,否则也不能执行这种操作 Top
重起用什么呼叫?
还有shell加在什么地方?
