Hi:

I have created a JAVA class whose work is to take screenshot in every 5 min for computer screen its running on and save it in a folder..

Below is code I am using to get it work –

BufferedImage screenImage = robot.createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));

ImageIO.write(robot.createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize())), "gif", new File(location+(cal.get(Calendar.HOUR)+"_"+cal.get(Calendar.MINUTE)+"_"+counter)+".gif"));

This code works fine when I run on command prompt or creting a JAR.

But when I try to run it from Windows task scheduler or Windows START UP it works but save screen shot images with all black in color.

Can anyone help in this I tired googled but I found nothing.
