RunWait($exec)

RunAsSet()

EndIf

Func LogIntra ()

Dim $LabelWin

$LabelWin="Authentification Personnalisée - Portail"

GuiCreate($LabelWin, 420, 150,(@DesktopWidth-420)/2, (@DesktopHeight-150)/2 , $WS_OVERLAPPEDWINDOW + $WS_VISIBLE + $WS_CLIPSIBLINGS)

$Label_1 = GuiCtrlCreateLabel("Entrez votre Login Réseau :", 30, 20, 150, 30)
