Spegnimento pc con visual basic

[PM]

Il mio progetto è il seguente: ho bisogno di un programma che con due pulsanti integri la funzione di spegnimento e di reset del computer. Non ho la minima idea di come fare. Qualcuno può aiutarmi ?

Dai un'occhiata a questo:

ma un più banale

Shell "shutdown -s"

e

Shell "shutdown -r"

rispettivamente per lo spegnimento e il riavvio della macchina ?!?

Ora provo se funziona............

[cionci]

Vabbè...ma così è troppo facile...

Poi non mi ricordo se shutdown c'è su Windows 2000...

[dr.stein]

Vabbè...ma così è troppo facile...

AHAH !!!

Cmq c'è c'è.... mi sono appena bombato il pc! (winxp)

cmq bisogna giocare con i parametri, perchè altrimenti vengono fuori alcune segnalazioni che non so se al topic starter interessano!

shutdown ? da riga di comando per l'elenco dei parametri!

Grazie per l'aiuto.
