Windows Screensaver Multi Monitor Problem

I have a simple screensaver that I've written, which has been deployed to all of our company's client PCs. As most of our PCs have dual monitors, I took care to ensure that the screensaver ran on both displays.

I have an application than disables the screen saver temporarily in order to run a slide show. I use this to turn it on or off: i = SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, active, Nothing, SPIF_SENDWININICHANGE) This works fine in XP. In Windows 7, it disables the screen saver properly.

screensaver hurts CUDA performance?

I've noticed that the running times of my CUDA kernels are almost tripled the moment the screensaver kicks in. This happens even if it's the blank screensaver. Oddly enough, this appears to have nothing to do with the power settings. When I disable the screen saver and let the screen power off, the performance stays the same. When I set...

I have a working screensaver and would like to figure out how I can control the name Windows displays in the screensaver drop down list.

I am writing an application in C# that plays a movie. I need to figure out how to disable the screen saver and power options using C#. I know the Windows SDK API has a function called SetThreadExecutionState() which can be used to do this, however, I do not know if there is a better way to do it.

Some of my friends suggested to use a Timer for this one. Any suggestion for a good head start? Thank...

Disabling screen saver programatically doesn't affect the control panel?
