Prevent screen saver from activating

[bkelly]

Windows 10, visual Studio, c++

There are some times when I want to prevent the screen saver for activating when there has been no input from the user. But not all the time.
What is the most simple way I can generate some data in an app and make the computer think someone pecked a key or moved the mouse?

This worked in win 7 and earlier, and I see no reason why it should not work in Win 10:

		int timeout;
		if(SystemParametersInfo(SPI_GETSCREENSAVETIMEOUT, 0, &timeout, 0))
			SystemParametersInfo(SPI_SETSCREENSAVETIMEOUT, timeout, NULL, 0);

You need to call it periodically, once every 30 seconds or so.

You may want to use SetThreadExecutionState in addition to the above - to prevent sleeping.
