c# - vérifier si l'économiseur d'écran est définie - Stack Overflow

How can I check if the user has set a screensaver, or if none is set:

I am not talking about starting screensaver, no, I am talking about check if a screensaver is set or not;) Anyone? Can I do this with P/Invoke?

Call SystemParametersInfo passing SPI_GETSCREENSAVEACTIVE. Note that for some versions of Windows this fails and you need to read the registry instead, as described here: http://support.microsoft.com/kb/318781

According to http://www.wikihow.com/Disable-Windows-Login-Screensaver

You can check the registry for a particular user's screensaver:

HKEY_USERS{user}\CONTROL PANEL\DESKTOP
