Arrêter la machine par un code VB 6

Bonjour

Je fais un projet en VB 6 sur WINDOWS 7 - 32 BIT.
Je voudrais donc mettre un bouton qui arrêtera la machine à partir de mon projet
J'ai trouver un code dans le FAQ'S de VB 6 dans ce forum qui est le suivant

Dans un module :
Code:

1 2 3 4 5 Public Const EWX_LOGOFF = 0 Public Const EWX_SHUTDOWN = 1 Public Const EWX_REBOOT = 2 Public Const EWX_FORCE = 4 Public Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Long, ByVal dwReserved As Long)
Dans un bouton :
Code:

1 2 3 Private Sub Command1_Click() ExitWindowsEx(EWX_SHUTDOWN, 0) = 1 End Sub
Quand j’appuie sur le bouton le message d'erreur suivant s'affiche : "Convention d'appel DLL incorrecte"

Pouvez-vous résoudre ce problème! merci d'avance!

Bonjour,

Code:

call ExitWindowsEx(EWX_SHUTDOWN, 0)

ou

Code:

ret= ExitWindowsEx(EWX_SHUTDOWN, 0)

ou

Code:

ExitWindowsEx EWX_SHUTDOWN, 0

Salut

Ça fait toujours la même erreur! "Convention d'appel DLL incorrecte"
Peut être qu'il y a une référence à ajouter? ou je ne sais pas quoi!

Code:

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

A ma connaissance, et si je ne me trompe pas, ce code n'a pas d'effet sur Win NT et Win XP.
Il ne marche qu'avec WIN9x et Win ME.
Il y a à peu près 5 ou 6 ans que j'ai essayé ce code sans succès.
Jusqu'à ce que (Merci à Apiguide) j'ai trouvé ce :
