  利用ExitWindowEx實現最簡單的關機功能

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

  參數:

  uFlags:     Long  //指定關閉的類型,類型有:

EWX_FORCE  //強制終止進程

EWX_LOGOFF    //關閉所有進程,然後登出使用者

EWX_POWEROFF  //關閉系統並關閉電源

EWX_REBOOT    //關閉系統,然後重新啟動系統

EWX_SHUTDOWN //關閉系統,安全地關閉電源

dwReserved:   Long  // 系統保留,一般為0

代碼實現如下

 

Option ExplicitPrivate Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long) As LongPrivate Const EWX_FORCE = 4    ‘強制終止進程Private Const EWX_LOGOFF = 0   ‘關閉所有進程,然後登出使用者Private Const EWX_REBOOT = 2   ‘關閉系統,然後重新啟動系統Private Const EWX_SHUTDOWN = 1 ‘關閉系統,安全地關閉電源。Private Sub Command1_Click() Dim i As Long i = ExitWindowsEx(EWX_REBOOT, 0) End Sub
