How to do this in Visual Basic?

Question

I need some help with my visual basic program I would like to to reboot the computer when the user clicks a button but cant get it to work, this is what ive got so far (that dosent work):

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Shell("RUNDLL32.EXE shell32,SHExitWindowsEx 2", AppWinStyle.NormalFocus)
End Sub

RUNDLL32.EXE shell32,SHExitWindowsEx 2 is meant to reboot the computer (someone told me) but it just dosent work so does anyone know how I can do it?

Answer 1

You need to make a Windows API call..."API" stands for "application programming interface", and is a collection of system functions not native to the visual basic environment. There are some good books on these kinds of functions. CHeck a local bookstore. Warning: incorrectly coding an API call can freeze the computer so you have to reboot.

Answer 2

Private Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long) As Long
Private Const EWX_FORCE = 4
Private Const EWX_LOGOFF = 0
Private Const EWX_REBOOT = 2
Private Const EWX_SHUTDOWN = 1

Private Sub cmdShutDown()
ExitWindowsEx EWX_SHUTDOWN, 0
End Sub
