Alguem pode me ajudar?

Criei um Form com Apenas um botão para desligar...
No botao coloquei esse comando :

[txt-color=#ff0000]Dim RetVal As Long
RetVal = ExitWindows(0, 0)[/txt-color]

E depois criei um modulo com o seguinte comando :

[txt-color=#ff0000]Declare Function ExitWindows Lib "user32" Alias "ExitWindowsEx" _
(ByVal uFlags As Long, _
ByVal dwReserved As Long) As Long
Public Const EWX_SHUTDOWN = 0[/txt-color]

Bom atÃ© ai ele roda sussegado... Mais enveis de desligar ele faiz logoff

ÃƒÃ¢â‚¬Å¡Ãƒâ€šÃ‚Â¬ÃƒÃ¢â‚¬Å¡Ãƒâ€šÃ‚Â¬

Alguem pode me ajudar como faço pra por esse progama pra funfa?
