Hi all,

Is there some way to activate the screen saver or to activate the Energy
Saving function; Power off monitor.



I would appreciate if I was able to power down my monitor when I leave the
PC.

Thanks
Jacob

You can activate Screen Saver via ShellExecute Win32 API 
function:

ShellExecute(GetDesktopWindow(),
"open","\"C:\\WINNT\\SysInternals Bluescreen.scr\""," /S",
    "C:\\",SW_SHOW);

This way should work (in my opinion) for Win98/Me/NT4/2000/XP.

Vladimir.

Not if you hard-code a path like that :-p  You would need to first call
GetWindowsDirectory() to determine where the Windows folder actually is, and
build up the path dynamically.

Also note that under Win9x/Me, at least, the screensaver filename is stored
in SYSTEM.INI, so you could read that value as well to ensure you're
actually starting the user's own configured screensaver.  I'm not sure where
NT/2K/XP stores it's configuration value, though.

Which, btw, ShellExecute() won't work on NT/2K/XP for this, anyway, because
those OSs run the ScreenSaver under a completely separate desktop of its
own, so there is extra processing involved in executing screensavers.

In both case (Win98, 2000) screen saver was run.
Besides these for Win98 it was not in Windows directory so 
probably not registered as Screen Saver.

But may be you right that was executed but not executed as 
screen saver - password dialog was not called.
But it is enoughly clear emulate the work of screen saver.
Do you try those code?
Vladimir.
