Can I prevent Screen Saver by J/Script ?

[justin1230smith]

Hi,

I have made a nice group of HTML pages for a company electronic notice board but the network security settings mean the screen saver comes on after 5 minutes and then powers off the screen after 20 !

This is not much good when I am trying to display these pages on a large screen

They will not relax the security policy for this one machine, nor for this one logon

Can I put some script in the HTML that simulates key strokes or better still mouse movements to fool Windows XP that someone is using the mouse

Thanks in advance,

Justin

JavaScript can read the keyboard and mouse inputs passed to it from the browser but has no access to generate such codes.

just tell the computer to not display screensaver.

Even regular programs running 0on the computer will not have the necessary access to be able to simulate the keypresses or mouse actions. A program would need to run at a special priviledge level within the optarating system to do that and if you have access to run programs that way you certainly have more than enough access to change the settings for the screensaver so as to not need to run such a program. The screensaver is easier to disable since it requires less access to the system than simulating keyboard or mouse actions do.

Its not only security- it is also energy conservation- a good thing.

Well if you have it as an electronic notice board, if you go into your power settings and select "Presentation" from the power schemes drop down, it will set your settings for you on monitor off... eg "Never"

Then set the screensaver to "None" and apply, your computer now shouldnt turn off the monitor unless you manually turn it off.

Thanks for all your replies, sounds like there is no way from a J/Script perspective to do this

Sadly the domains security settings do not allow me access to turn off the screen saver or adjust the power scheme settings. (Which was the first place I looked)

I have had some people suggest a little app that I can download that runs as a service and prevents the screensaver but if I get caught installing apps, especially one that in effect circumvents their security settings, then I think I might get in trouble.

Thanks for your efforts though !

Your only option is to put your case to the network administrator to get that particular machines settings changed, your network admin shouldnt object to this because by the sounds of it your asking a reasonable request for using the machine in a specific way and the current settings for the machine are problematic in as far as it interrupts the 'eNB' and isnt helpful at all.

If your network admin refuses to change the settings, your next option is to go to your boss ot immediate supervisor that has more clout and kick the muppets ass because THEIRS NO security issues, I take it the system runs on that machine and that machine only? If your given the blow off about security, you can point out that a "Network Administrator" in an online forum told you that theirs no security issue and the request was considered reasonable and to stop being a pedantic ass hole... or words to that effect.
