Buenas estado buscando como suspender el pc desde VB en google y solo encontrado como apagarlo/reiniciarlo utilizando las APIs pero no como suspenderlo, alguien me puede orientar un poco?

Hola,yo tengo aca un codigo que use en un programa para apagar el monitor..pero lo que hace realmente es suspender la pc y dejarla en standby digamos y al mover el mouse se reestablece todo,pero a algunos tambien los desconectaba de intenet..pero a mi no me paso...lo hace a travez de api's pero con Token Privileges..no se si te sirva...

saludos.

Api Guide:

Para saber si esta permitido el hibernado, apagado y/o suspendido:

Private Declare Function IsPwrShutdownAllowed Lib "Powrprof.dll" () As Long
Private Declare Function IsPwrSuspendAllowed Lib "Powrprof.dll" () As Long
Private Declare Function IsPwrHibernateAllowed Lib "Powrprof.dll" () As Long

    Debug.Print "Suspend Allowed: " + CStr(CBool(IsPwrSuspendAllowed))
    Debug.Print "Hibernate Allowed: " + CStr(CBool(IsPwrHibernateAllowed))
End Sub
