I don't understnad - what is the difference between what George's class does, and what you would like to do? You might address email to him asking about the details of what he's actually doing internally.
The SystemParametersInfo() API call does a couple of things with the screen saver; it can enable/disable the current screen saver via the SPI_SETSCREENSAVEACTIVE action, which takes a BOOL (a SHORT with a value of 0 for false or 1 for true) for the uParam argument, and you can adjust the timeout delay for the screen saver via the SPI_SETSCREENSAVETIMEOUT action, which takes a number of seconds as a LONG for the uParam argument. Beyond that, I don't know; I do not program screen savers, and my needs are quite satisifed with these things.
You'll need to experiment to see how to use the API call to accomplish what you want. You might want to research the ScreenSaverConfigureDialog() API call and trhe Windows Shell Messages in the MSDN docmentation.

As I said in my first message, i don't know what the handle for the default screen saver is; you're going to have to look into it yourself.

>The easiest way would be to use George Tasker's class in the Files section here on UT. In order to shut down the current screen saver, you either must use SendMessage() to message the screen saver, or better, to use SystemParametersInfo() with the SPI_SETSCREENSAVEACTIVE action. You'll need to look at how to set this up in the API documentation; if you have Visual Studio, it's documented in the API Help file, with specific values defined in WINBASE.H in the Visual C++ INCLUDES directory. SystemParametersInfo() should be callable for this directly from VFP without needing a wrapper function.

You can send requests to the screen saver via SendMessage() (you'd have to find the Window Handle for the screen saver first, and then send the appropriate message; I have no clue as to what messages are accepted by screen savers, or the Window name for the screen saver to use the FindWindow() function to get it.)
