Avoid screensaver

[rrandom]

Dear readers,

for a programmer it could be less than 4 lines code?

For a designer it could be a needed help.

To avoid the start of a screensaver (managed via admin) some action must happen during a tme interval.

If the mouse is moving 1px forwards and 1px backwards (via x) every 3 minutes, the problem would be solved.

Are 4 lines of code needed, or can it be done with 3 or 2 lines?

Thank you for your interest

i would suggest posting an example and letting other critique it

HotKeySet("^{ESC}", "_Exit")

GLobal $hTimer = TimerInit(), $fClose = False
While 1
    If TimerDiff($hTimer) >= 3 * 60000 Then
        $aPos = MouseGetPos()
        MouseMove($aPos[0] + 1, aPos[1], 0)
        MouseMove($aPos[0], aPos[1], 0)
        $hTimer = TimerInit()
    EndIf
    If $fClose Then
        ExitLoop
    EndIf
    Sleep(10) ;Sleep to avoid high CPU usage
WEnd

Func _Exit()
    $fClose = True
EndFunc

Does it have to be under 4 lines?

[mrider]

Are 4 lines of code needed, or can it be done with 3 or 2 lines?

 

Something to keep in mind: There's software you write for yourself, and there's software you write for others.  When I write a utility or program for myself, I often times skip some of the various error traps and things that make a program bullet-proof - or at least bullet resistant.  When the software is intended for others, I often have to add numerous lines of code to make sure it won't explode in a user's face.

A "real" program, meant to be used in production by actual users is often times 80% safety code, and 20% algorithms (if you'll forgive me pulling a number out of my arse).  So it's likely someone can make a really short program, but it probably won't be very forgiving.  For example, what happens if the mouse starts at the top of the monitor?  How is it going to move even further up?

Or just disable it

RegWrite("HKEY_CURRENT_USER\Control Panel\Desktop", "ScreenSaveActive", "REG_SZ", "0") ; Disable Screensaver

'?do=embed' frameborder='0' data-embedContent>>

that is more than 4 lines Mr Eyeball...

That's just an example. You write the code if you want it to be 4 lines.

Understand?

It's moving the mouse 1 pixel left and then back.

 

 

Or just disable it

RegWrite("HKEY_CURRENT_USERControl PanelDesktop", "ScreenSaveActive", "REG_SZ", "0") ; Disable Screensaver

 

Clever.

EDIT:

Enhanced "you"'s

Understand what? That YOU have no sense of humor?

I posted an example to show you the concept.

I just don't understand why it would have to be 4 lines, it makes no sense at all.

[l3ill]

It doesnt. I was just joking... (See original query)

Sorry if it came across any other way... 

[mrider]

My statement wasn't aimed at you, so no need to make the correction.  Besides which, what if it was at the left instead of top?

 

However, that's precisley my point.  The point being that one needs to think about how the software is going to be used and by whom.  For example, I can disable the screensaver in the registry as Chimaera suggests, however, it'll magically reenable itself after a short time.  The desktop computers here have a process running in the background that ensures various sanity settings are always set to the corporate standard: One of those sanity checks being that desktops lock after a certain time period.

My point being that fewer lines of code run a greater risk of hitting some edge case that causes it to fail.  That's fine if the software is intended for your own use, but it may or may not be fine for others.

My own don't-sleep script (which is longer than 3 lines and can fail if the mouse is in the upper right corner) looks like this:

$index = 0
While True
    $mouse_xy = MouseGetPos()
    If BitAND($index, 1) = 1 Then
        MouseMove($mouse_xy[0] + 1, $mouse_xy[1] + 1)
    Else
        MouseMove($mouse_xy[0] - 1, $mouse_xy[1] - 1)
    EndIf
    $index += 1
    Sleep(5 * 60 * 1000)
WEnd

[DatMCEyeBall]

And yet we still don't have a reason for it having to be 4 lines.

[NewPlaza]

How about this?

Local $mouse_xy
While True
    $mouse_xy = MouseGetPos()
    MouseMove($mouse_xy[0] + 1, $mouse_xy[1])
    MouseMove($mouse_xy[0] - 1, $mouse_xy[1])
    Sleep(5 * 60 * 1)
WEnd

Sure.. It's not 4 lines... But ii should work.

EDIT: Yeah you need to change the sleep to your needs.

The one I use 24/7 and has never failed me (although it too is more than 4 lines)

While 1
$pos = MouseGetPos()
$x = $pos[0]
$y = $pos[1]
If $x<1023/2 And $y<767/2 Then MouseMove($x + 5,$y + 5)
If $x>1023/2 And $y>767/2 Then MouseMove($x - 5,$y - 5)
If $x<1023/2 And $y>767/2 Then MouseMove($x + 5,$y - 5)
If $x>1023/2 And $y<767/2 Then MouseMove($x - 5,$y + 5)
    Sleep(300000)
WEnd

Although it's very old and was one of the first scripts I made. Looking at my source here, a couple changes would be to skip defining $x and $y and just use the $pos array

and the other change would be using the desktop width and height macros instead of the pre-defined resolution I was using.

[NewPlaza]

Perhaps I'm looking at it wrong but...

Why do any checks on where the mouse is and how big the desktop resolution is?

The mouse should already be in a useable area of the desktop. just move one right then one left.  Why test?

 

 

Or just disable it

RegWrite("HKEY_CURRENT_USERControl PanelDesktop", "ScreenSaveActive", "REG_SZ", "0") ; Disable Screensaver

 

 

I wished I could use this. But alot of my settings at login is control by the AD.

Question answered even before it's asked, all in the same post.  (I take it you've never pushed your mouse way off to one side to clear desktop space...)

I'm not arguing with you.  Really.  You'll note that I don't check in my own post.  Again, all I'm saying is that one needs to think before coding, and that "fewest lines of code" doesn't automatically translate to "best way to do it".

 

[EDIT] "And yet we still don't have a reason for it having to be 4 lines."

Agreed...

I do this so that when it comes to move the mouse, it moves it towards the center of the screen. That way it never gets stuck in a corner or at the edge. And by moving it 5px, it a slight enough move to not be noticed, but also enough that the cursor should never reach dead center so it will always meet one of the conditions to move towards the center

A timer would be better than using Sleep().
