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

Private Sub Form_Load()
    msg = MsgBox("This program is going to reboot your computer. Press OK to continue or Cancel to stop.", vbCritical + vbOKCancel + 256, App.Title)
    If msg = vbCancel Then End
