I stumbled across this recent support thread on using multiple "stopwatches", so I thought I would have a little fun and make a full-featured stopwatch object using AutoItObject_Internal.au3 by @genius257.  It's not super useful, but who doesn't like a full UDF for the simplest of tasks?
This is more of a proof of concept and is not meant to be extremely accurate or reliable, but I'm still open to suggestions if anyone has any ideas for improvement.

The stopwatch has the following methods:

  • start: start (or restart) the timer and reset the accumulated timer value
  • stop: stop/pause the timer
  • lap: return the time since the last time lap was called or since the timer was started
  • reset: stop and reset the timer
  • elapsed: get the time since the last reset or since the timer was started

To use a stopwatch, simply create a new object and start the timer. You can then retrieve the total elapsed time or the current lap time. 

#include "ObjStopwatch.au3"

$oStopwatch1 = _ObjStopwatch()
$oStopwatch1.start()
sleep(500)
consolewrite("Lap time: " & $oStopwatch1.lap() & @CRLF)
sleep(500)
consolewrite("Total time: " & $oStopwatch1.elapsed() & @CRLF)

The .elapsed method has 1 optional parameter to set the return formatting. 

; Syntax.........: _ObjStopwatch_elapsed ( [$iFormat = 0] )
; Parameters ....: $iFormat = desired format
;                   - 0 = ms with decimal (same as TimerDiff())
;                   - 1 = hh:mm:ss
;                   - 2 = hh:mm:ss:0ms
;                   - 3 = hh:mm:ss.0

Similarly, the .lap method has 2 optional parameters. By passing False as the 2nd parameter, you can poll the current lap time without triggering a new lap. 

; Syntax.........: _ObjStopwatch_lap ( [ $iFormat = 0 [, $bNewLap = True ]] )
; Parameters ....: $iFormat = desired format
;                   - 0 = ms with decimal (same as TimerDiff())
;                   - 1 = hh:mm:ss
;                   - 2 = hh:mm:ss:0ms
;                   - 3 = hh:mm:ss.0
;                  $bNewLap = Return the current lap time, and reset lap timer

The real power of this UDF (really all thanks for AutoItObject_Internal) is the ability to create as many Stopwatch objects as you want, which you are then free to start and stop independently. 

#include "ObjStopwatch.au3"

$oStopwatch1 = _ObjStopwatch()
$oStopwatch2 = _ObjStopwatch()
$oStopwatch3 = _ObjStopwatch()
$oStopwatch4 = _ObjStopwatch()

$oStopwatch1.start()
$oStopwatch2.start()
Sleep(500)
$oStopwatch1.stop()
Sleep(500)
consolewrite("Stopwatch 1: " & $oStopwatch1.elapsed() & @CRLF)
consolewrite("Stopwatch 2: " & $oStopwatch2.elapsed() & @CRLF)

Lastly, here is a simple GUI example for recording the lap times of 2 different stopwatches.

#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include "ObjStopwatch.au3"

hey, I thought I'd do the same thing using @genius257's own AutoItObject_Internal
Thanks for saving me the trouble.... :)
Nice work of course, and also an interesting usage example for the AutoItObject_Internal.

Works fine for me on 3.3.14.5.

Thanks

@Gianni Actually, I saw a few random crashes when testing it but it was so few and far between that I chalked it up to hitting F5 too fast between runs. I ended up putting the COM error handler in the example to try and catch that crash, but I couldn't get it to happen again.

Well I tried getting it to crash again and it took about 20 tries but it finally crashed. It showed the GUI briefly then disappeared and gave the following exit code. I'm not sure how to troubleshoot since it doesn't appear to be a COM error and it's not a normal error that is reported in the console - just a silent crash. For now I'm adding a bunch of log messages to see where it might be crashing.
I'm using v3.3.16.0.

Hi @kurtykurtyboy.

That error code translates to 0xC0000005 (Access Violation).

It occurs when non accessible data access is attempted.

Mostly it happens when freed memory is accessed and the now possibly random data end up being used as a pointer to a non accessible memory pointer reference.

If it's my code only at fault, it is a tedious, but easy process of finding the faulty code. However i have found that some VERY specific cases can result in AutoIt3 crashing, that seems to be an issue with AutoIt3. see this issue i have in another project of mine for example. Trouble is confirming that is is not my code being the culprit is hard when it comes to memory manipulation and complex scenarios.

My highlighted topics: AutoIt Package Manager, AutoItObject Pure AutoIt, AutoIt extension for Visual Studio Code

Github: AutoIt HTTP Server, AutoIt HTML Parser

I still did a small test using the "Simple Gui Example" script present in the spoiler of the first post, and I modified this portion of code 

While 1
        ConsoleWrite("Debug 1" & @CRLF)
        $Time1 = $oStopwatch1.elapsed(2)
        ConsoleWrite("Debug 2" & @CRLF)
        $Time2 = $oStopwatch2.elapsed(2)
        ConsoleWrite("Debug 3" & @CRLF)

        ;timer to slow down label flicker
        If TimerDiff($displayTimer) > 100 Then
            If $Time1 <> $prevTime1 Then
                GUICtrlSetData($label_time1, $Time1)
                $prevTime1 = $Time1
            EndIf
            ConsoleWrite("Debug 4" & @CRLF)
            If $Time2 <> $prevTime2 Then
                GUICtrlSetData($label_time2, $Time2)
                $prevTime2 = $Time2
            EndIf

            $displayTimer = TimerInit()
        EndIf

        Sleep(10)
        ConsoleWrite("Debug 5" & @CRLF)
    WEnd

where I added some consolewrite to see where the script crashes and it seems that the line that he does not like is $time2 = $stopwatch2.elaPsed (2)
I tried the script on two different computers (both with Win10 Pro x64) and I receive two different crash type:
This on a computer: 

Debug 1
Debug 2
Debug 3
Debug 5
Debug 1
Debug 2
!>17:13:05 AutoIt3.exe ended.rc:-1073741819
+>17:13:05 AutoIt3Wrapper Finished.
>Exit code: 3221225477    Time: 8.258

And this on another computer: 

Debug 1
Debug 2
Debug 3
Debug 5
Debug 1
!>17:23:36 AutoIt3.exe ended.rc:255
+>17:23:36 AutoIt3Wrapper Finished.
>Exit code: 255    Time: 12.38

... just for the record ...
