I've thought about making something that does exactly what you're doing here, but never knew enough Windows programming to do it.  Nice work!

This is a nice utility, what language do you use to create this?

It is an easy little scriping language called AutoIt.  Similar to VB Script, but it has GUI functionallity, and compiles to an EXE which is kind of handy.

Only about 30 lines of code total, most of which is setting up he tray icon.  The actual mouse moving code is only 6 lines.  Basically tells it, until someone closes the app, idle around for 30 seconds, then get the position of the mouse and move it right and left one pixel.  Then it loops and idles around fr 30 more seconds.

While 1
    Sleep(30000)
    $CurPos = MouseGetPos ( )
    MouseMove ( $CurPos[0] + 1, $CurPos[1] )
    MouseMove ( $CurPos[0] - 1, $CurPos[1] )
WEnd

Check out www.autoitscript.com if you are interested.  I do most my stuff in C#, but sometimes,  a simple script is all you need.

Cheers

Looks like this approach should work well with Win 7 .  Would you mind sharing your 30 lines of full source code behind this.. perhaps include in your Winzip?     In our case, would be good if such a facility self-exited after so much time  - especially for conference rooms - and wouldn't take too much to enhance further.

Nice job!

Sure, here is the entire source code.  I will update the zip so it contains the uncompiled version as well.

Opt("TrayOnEventMode",1)
Opt("TrayMenuMode",1)

$AboutItem = TrayCreateItem("About")
TrayItemSetOnEvent(-1,"ReadList")
TrayCreateItem("")
$ExitItem = TrayCreateItem("Exit")
TrayItemSetOnEvent(-1,"ReadList")

Func ReadList()
 $SelectedItem = TrayItemGetText(@TRAY_ID)
 If $SelectedItem="Exit" Then
  Exit
 ElseIf $SelectedItem="About" Then
  Call("About")
 EndIf
EndFunc

Func About()
 MsgBox(064,"No Sleep Utility","Prevents your computer from automatically locking or going to screen saver as it normally would." & @CRLF & "Copyright Mike Langford ©2009")
EndFunc

While 1
 Sleep(30000)
 $CurPos = MouseGetPos ( )
 MouseMove ( $CurPos[0] + 1, $CurPos[1] )
 MouseMove ( $CurPos[0] - 1, $CurPos[1] )
WEnd

FYI,
The ZIP now contains the Au3 file, which is just text based source code that Autoit can compile to an EXE.

Thanks for the code.  Looks pretty straight forward!

This causes my cursor to end up 2 pixels to the left every time.

You sir, are a genius! 

Thank you so much! 

This is genuine utility can we use in corporate?

Hmmmm.. not bad. This won't work for everything though. If you just want the computer not to lock this will work in most(not all) circumstances(Win7, Win8, UAC. Many more things to consider these days). Attached is a utility I wrote. Its in C# and uses pInvoke to get the exact timeouts for each profile and then adjusts the reset values accordingly. This will not move your mouse or type phantom characters like some do. This will also make you appear active on OCS, gchat, Lync, Outlook,etc. This works on ANY Windows version under any type ofdomain or individual security policy(GPOs). This utility is more meant to make you appear that you are actually at your terminal working even if you step away. Really it was written as a POC. The file ImWorkin.exe is in the root of the zip if you just want the pre-copmpiled exed. Otherwise the whole C# project is there for you too.

I dont condone slacking off but at times you may find a need for this utility. Use it wisely and dont abuse it too much because ultimatley it doesnt matter how your computer look if you arent actually producing your deliverables to your managment!

Enjoy

Source included in the zip.....Requires .NET 4 or above.
