That is not the correct way to pass the boolean. You have to use the '&'
operator instead:
BOOL IsScreenSave;
SystemParametersInfo(SPI_GETSCREENSAVEACTIVE, 0, &IsScreenSave, 0);

As it should be. You are not preventing it from running at all.
SPI_SETSCREENSAVEACTIVE does not deactive the screensaver if it is already
running. It is only a flag to tell the OS whether the screensaver is
running or not. Screensavers use SPI_SETSCREENSAVEACTIVE when they run. If
anything, you should be setting SPI_SETSCREENSAVEACTIVE to TRUE instead of
FALSE to trick the OS into thinking a screensaver is running when none
actually is. That way, the actual screen saver will not kick in until you
set SPI_SETSCREENSAVEACTIVE back to FALSE later.
