关机功能在使用Windows API时执行注销窗口

Question

我已使用以下代码关闭系统但它将执行注销窗口

Private Const EWX_LogOff = 0  
Private Const EWX_SHUTDOWN = 1  
Private Const EWX_REBOOT = 2  
Private Const EWX_FORCE = 4  

Public Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long

Public Sub ShutDownComputer()  
  Call ExitWindowsEx(EWX_FORCE, &HFFFFFFFF)   
End Sub 

Answer 1

试试这个

Private Const EWX_POWEROFF = 8 
Call ExitWindowsEx(EWX_POWEROFF, &HFFFFFFFF)

Answer 2

尝试将SHUTDOWN与FORCE结合使用。

Answer 3

除了Eugene所说的，最好使用pinvoke的声明：

Declare Function ExitWindowsEx Lib "user32" (ByVal dwOptions As Int32, ByVal dwReserved As Int32) As Int32

声明为两个四字节整数的参数（作为dll中的ExitWindowsEx函数）。
