waking a sleeping monitor with python?

[darter]

Would anyone have ideas on how I can 'wake' a monitor once a day using a script such as python? So ... my desktop computer in always on but at noon I would like the monitor to change from black to showing a message. I'm using Windows XP.

You'll need http://sourceforge.net/projects/pywin32/ if you dont have it already.
Give this a try.

Code: Select all

import time
import win32gui
import win32con

MONITOR_ON = -1
MONITOR_STANDBY = 1
MONITOR_OFF = 2
SC_MONITORPOWER = 0xF170

def monitorControl(state=MONITOR_ON):
    win32gui.SendMessage(win32con.HWND_BROADCAST, win32con.WM_SYSCOMMAND,
                                                    SC_MONITORPOWER, state)

if __name__ == "__main__":
    monitorControl(MONITOR_OFF)
    time.sleep(5)
    monitorControl(MONITOR_ON)

Thanks. Works great on my XP machine. I also have a Window 7 laptop that I'm operating remotely and I am hoping it with work with Windows 7. On the remote machine I just want to be careful that I don't crash it.
