Question

ctypes.windll.user32.mouse_event(3, 0, 0, 0,0)

I\'m messing around with mouse positions and stumbled upon this line which from what I understand emu

Answer 1

This is from http://blog.lazynice.net/?p=63.

The script detect the windows’s inactivity every minute. If the inactivity exceeds 5 minutes, it simply sends an mouse event that move the mouse a little, so the screensaver may think it comes from the user input then reset the timer. Just set the inactivity duration less than the screensaver’s waiting time then run it!

from ctypes import Structure, windll, c_uint, sizeof, byref
import time

class LASTINPUTINFO(Structure):
    _fields_ = [('cbSize', c_uint), ('dwTime', c_uint)]

def get_idle_duration():
    lastInputInfo = LASTINPUTINFO()
    lastInputInfo.cbSize = sizeof(lastInputInfo)
    windll.user32.GetLastInputInfo(byref(lastInputInfo)) 
    millis = windll.kernel32.GetTickCount() - lastInputInfo.dwTime
    return millis / 1000.0

while True:
    d = get_idle_duration()
    if d > 60 * 5:
        windll.user32.mouse_event(1, 1, 1, 0, 0)
    time.sleep(60)
