how can I measure the time of computer use?

[GiulioM]

I'm working to a time limitation program, so how I would like to know if there is a function to measure time; if it doesn't exists, please suggest me a similar function.

[Melba23]

GiulioM,

Go and read the Help file. There are plenty of commands in AutoIt to read and measure both time and date.

If you run into problems, post the code here and we will help you get over them.

There is not one function I know of... but maybe this gives you want you need ...

It extracts when explorer.exe was created... not sure, but I think it might be the time the user logged on for the first time...

I believe the particular tool you want to call on is "psloggedon.exe" running the aforementioned command w/o switches will give you the current logon status of all local users, including the user's original logon time (I've been logged into this machine for 36 weeks??? Madness!!)

use psloggedon.exe /? for a list of switches and options

This is not fast but it's about as accurate as you can get.

#include<array.au3>
$sTempFile = @TempDir & "\sys.tmp"
$sSystem = RunWait(@ComSpec & " /c " & 'SystemInfo > ' & $sTempFile, "", @SW_HIDE)
$s_Str = FileRead($sTempFile)
FileDelete($sTempFile)
$aBootTime = StringRegExp($s_Str, "(?i)(?m:^).+time:\s*(\d.*)\v", 1)
If Not @Error Then
    $s_Rtn = StringRegExpReplace($aBootTime[0], "\s*,\s*", ",")
    $a_Rtn = StringSplit($s_Rtn, ",", 2)
    _ArrayDisplay($a_Rtn)
EndIf

Where $a_Rtn[0] Contains the startup date and $a_Rtn[1] contains the time. You could easily work this up into a function.
