Detecting the ScreenSaver State

[Anthony]

In C++ you can detect the screensaver state by using something like:

BOOL b=SystemParamet ersInfo(SPI_GET SCREENSAVERRUNN ING, NULL, &bOn, FALSE);

Is there an equivalent method that I can use in C#? If not, how can I
determine the state of the screen saver?

This is from one of the forums, so you can test it yourself, but the idea is
to use interop to get the state from the SPI enum:

[DllImport("user 32.dll", CharSet=CharSet .Auto)]
public static extern int SystemParameter sInfo(int uAction,
int uParam, ref int lpvParam, int fuWinIni);

const int SPI_GETSCREENSA VERRUNNING = 114;
int screenSaverRunn ing = -1;

// is the screen saver running?

int ok = SystemParameter sInfo(SPI_GETSC REENSAVERRUNNIN G, 0, ref
screenSaverRunn ing, 0);

if (ok == 0)
{
Console.WriteLi ne("Call to SystemParameter sInfo failed.");
}

if (screenSaverRun ning != 0)
{
// screen saver is running

}

ok,
