Windows lock screen and then turn off the monitor, executable program

Sometimes we need to close the screen to have a rest or write something on Ben, but it's distracting when the screen is on, but it's too much trouble to turn off the monitor, so go straight to a small program (non-applet). There is a situation, sometimes at night to leave the computer next, but the computer is still doing things, do not want to shut down the computer, and because the night is dark, the screen will be scolded, combined with the above situation, this terminal code is very suitable for you.

If you don't compile the code, it's okay, I have the compiled executable file here, download link http://www.yxxrui.cn/article/71.shtml
