Michel,

The Const 17 stands for SPI_SETSCREENSAVEACTIVE which actually toggles the
creation\removal of a screensaver like when the user selects a sreensaver
through Control Panel.This is not what I am after. What I want is to be able
to temporarly interrupt a running screensaver like when the users moves the
Mouse or press a key.

Steve's solution via using the WMI is the only one I have seen so far that
works !

Being essentially an API wrapper,the WMI Lib indicates that there must exist
a solution using APIs alone. I would be interested to know how that is done
for the sake of learning and also because relying on WSH, WMI is not
foolproof as these external Libs can often be disabled by network
administrators.

On the other hand, using APIs for this would guaranty that the code always
work in any machine running Windows .

Thanks for the input though Michel.

Regards.

Hi RAFAAJ2000,
You can try:

Private Declare Function SystemParametersInfo& _
Lib "user32" Alias "SystemParametersInfoA" _
(ByVal uAction As Long, ByVal uParam As Long _
, ByRef lpvParam As Any, ByVal fuWinIni As Long)

Sub ScreenSaverOff()
Call SetScreenSaver(False)
End Sub

Sub ScreenSaverOn()
Call SetScreenSaver(True)
End Sub

Private Sub SetScreenSaver(ByVal Enable As Boolean)
Dim Ret As Long
Ret = SystemParametersInfo(17, Enable, ByVal 0, 0)
If Ret = 0 Then MsgBox "Error !", 64
End Sub

Steve,

Fantastic !....It works beautifully !......It never occured to me to use
the
WMI for solving this . I had been only exploring APIs so far.

Thank you very much indeed. :)

I am still curious to see a pure API solution only for the sake of
learning :)

Regards.

Hi,

I am trying to turnoff a screensaver as soon as it kicks off.

I know how to detect if a screen saver is currently running via
SPI_GETSCREENSAVERRUNNING but I can't seem to STOP it once it has
kicked
off
programmatically.

I have tried simulating a Mouse Move or SendKey and even using the
SendMessage with the WM_CLOSE Msg but no luck !

Actually, I ma not sure about this, but it looks as if no code is
executed
once the screensaver kicks off as the lines of code subsequent to the
screensaver starting don't execute !

I am doing this in an XL macro under XL2002 WIN XP.

Any help on this ?

Regards.
