How to prevent Screen Saver from turning on

[spiritofklanawa]

I'm generating an animation on the screen and the screen saver kicks in since there is no keyboard/mouse interaction from the user. Is there any MFC/Win32 to reset the screen saver timer ? Worst comes to worse I might try a SendMessage() with WM_COMMAND/BN_CLICKED periodically to simulate user interaction but there must be some more elegant solution. Thanks for your input Alex

You could try using the SystemParametersInfo() function with the SPI_SETSCREENSAVEACTIVE action.

Call SetThreadExecutionState(ES_DISPLAY_REQUIRED) to tell the system that you're using the display.

From MSDN[^]: [quote] This function does not stop the screen saver from executing either. [/quote]

Those docs need some cleanup, since they also say:

Multimedia applications, such as video players and presentation applications, must use ES_DISPLAY_REQUIRED when they display video for long periods of time without user input.
