How do you keep the machine awake?

I use this code to keep my workstation from locking. It's currently only set to move the mouse once every minute, you could easily adjust it though.

It's a hack, not an elegant solution.

import java.awt.*;import java.util.*;public class Hal{    public static void main(String[] args) throws Exception{        Robot hal = new Robot();        Random random = new Random();        while(true){            hal.delay(1000 * 60);            int x = random.nextInt() % 640;            int y = random.nextInt() % 480;            hal.mouseMove(x,y);        }    }}

On Windows, use the SystemParametersInfo function. It's a Swiss army-style function that lets you get/set all sorts of system settings.

To disable the screen shutting off, for instance:

SystemParametersInfo( SPI_SETPOWEROFFACTIVE, 0, NULL, 0 );

Just be sure to set it back when you're done...

Adding to scarcher2's code snippet above and moving mouse by only 1 pixel. I have moved the mouse twice so that some change occurs even if pointer is on extremes:

while(true){            hal.delay(1000 * 30);                   Point pObj = MouseInfo.getPointerInfo().getLocation();            System.out.println(pObj.toString() + "x>>" + pObj.x + "  y>>" + pObj.y);            hal.mouseMove(pObj.x + 1, pObj.y + 1);              hal.mouseMove(pObj.x - 1, pObj.y - 1);            pObj = MouseInfo.getPointerInfo().getLocation();            System.out.println(pObj.toString() + "x>>" + pObj.x + "  y>>" + pObj.y);        }
