How To Turn Computer Off Using VB??

[carpocalyspe]

Hi there.

i was wondering if anyone knew how to turn a computer off using Visual Basic. Like a Subroutine what turns the computer off when referred to.

Private Declare Function ExitWindowsEx Lib "User32" ( _
 ByVal dwOptions As Long, _
 ByVal dwReserved As Long) As Long
 
Private Const EWX_SHUTDOWN = 1
Private Const EWX_FORCE = 4
 
Public Sub ShutDown(Optional blnForce As Boolean)
    Dim nFlags As Long
 
    nFlags = EWX_SHUTDOWN + IIf(blnForce, EWX_FORCE, 0)
    Call ExitWindowsEx(nFlags, 0&)
End Sub

You could also use this command (on XP)

Shut down a server in a controlled manner.
 
TSSHUTDN [wait_time] [/SERVER:servername] [/REBOOT] [/POWERDOWN]
         [/DELAY:logoffdelay] [/V]
 
  wait_time           Seconds to wait after user notification before
                      terminating all user sessions (default is 60).
  /SERVER:servername  The server to shut down (default is current).
  /REBOOT             Reboot the server after user sessions are terminated.
  /POWERDOWN          The server will prepare for powering off.
  /DELAY:logoffdelay  Seconds to wait after logging off all connected
                      sessions (default is 30).
  /V                  Display information about actions being performed.

You can shut of networked computers this way, also
