      Hello everyone, I am working on a project which requires reading a few values from Excel, the catch is that I need it to be very fast... unfortunatley I found out that read operations using the supplied Excel UDF are very slow, more than 150 ms for each operation on average
      Here is my testing setup that I made:
      #include <Excel.au3> #include <MsgBoxConstants.au3> Global $iTotalTime = 0 Test() Func Test() Local $oExcel = _Excel_Open() Local $oBook = _Excel_BookAttach("Test.xlsx", "FileName", $oExcel) Local $sSheet = "Sheet1" If @error Then Return MsgBox($MB_ICONERROR, "Excel Failed", "Failed to attach to Excel") Local $iNum For $iRow = 1 To 6 Time() Local $iNum = Number(_Excel_RangeRead($oBook, $sSheet, "A" & $iRow)) If ($iNum = 1) Then ConsoleWrite("Row " & $iRow & " is 1 and value of column B is " & _Excel_RangeRead($oBook, $sSheet, "B" & $iRow)) Else ConsoleWrite("Row " & $iRow & " is not 1") EndIf ConsoleWrite(". Reading took: ") Time() Next ConsoleWrite("The whole operation took " & $iTotalTime & " milliseconds." & @CRLF) EndFunc Func Time() Local Static $hTimer Local Static $bRunning = False If $bRunning Then Local $iTime = Round(TimerDiff($hTimer), 2) $iTotalTime += $iTime ConsoleWrite($iTime & @CRLF) Else $hTimer = TimerInit() EndIf $bRunning = Not $bRunning EndFunc And Test.xlsx in CSV format:
      1,-1 -1,1 1,-1 1,1 -1,-1 1,1 Here is the actual xlsx but it should expire in a week: https://we.tl/t-EVkxGp1kc6
      And finally output from my script:
      Row 1 is 1 and value of column B is -1. Reading took: 276.06 Row 2 is not 1. Reading took: 163.36 Row 3 is 1 and value of column B is -1. Reading took: 302.58 Row 4 is 1 and value of column B is 1. Reading took: 294.65 Row 5 is not 1. Reading took: 152.33 Row 6 is 1 and value of column B is 1. Reading took: 284.92 The whole operation took 1473.9 milliseconds.  
      Taking ~1.5 seconds for reading 6 rows of data is bad for my script, which needs to run as fast as possible . It would be nice if I can bring this down to 100 ms somehow, I am not very experienced working with MS office so I thought about asking you folks for help and advice on how I can optimize my script to squeeze out every bit of performance that I can get from this script
       
      Thanks for the help in advance!

      If you press the "Login" button in the top-left of https://www.showroom-live.com/, it creates a popup in which you press "Login with Twitter ID", which then opens a new window with an "Authorize app" button.
      None of these 3 buttons have a Name or ID, so how do I click on them, because _IEGetObjByName / _IEGetObjByID will not work.
      Here are the sources of the 3 buttons:
      ;Login button. ;<a onclick="showLoginDialog();" href="javascript:void(0);">Login</a> ;Twitter button (Note that I am already signed into Twitter and just need to Authorize it). ;<a class="btn-twitter btn-sky-blue submit fs-b5" onclick="window.open('/social/twitter/redirect_authorize_url?login=1&from_browser=1', 'twitter', 'width=500,height=400,menubar=yes,status=yes,scrollbars=yes');" href="javascript:void(0);">Login with Twitter ID</a> ;Popup window appears. ;<input class="submit button selected" id="allow" type="submit" value="Authorize app"> I have also tried:
      Local $oLinks = _IETagNameGetCollection($ie, "a") For $oLink In $oLinks If $oLink.InnerText = "showLoginDialog()" Then _IEAction($oLink, "Click") ExitLoop EndIf Next I've even tried adding "showLoginDialog()" and "javascript:void(0)" to the end of the URL, but as expected, that wouldn't work either.
      My goal is something like this:
      #include <IE.au3> Local $ie = _IECreate("https://www.showroom-live.com/onlive") _IELoadWait($ie) Local $originalHandle = $ie ;===Functions========================================================== Func login() ;Source: <a onclick="showLoginDialog();" href="javascript:void(0);">Login</a> _IEAction(ABOVESOURCE, "Click") ;Source: <a class="btn-twitter btn-sky-blue submit fs-b5" onclick="window.open('/social/twitter/redirect_authorize_url?login=1&amp;from_browser=1', 'twitter', 'width=500,height=400,menubar=yes,status=yes,scrollbars=yes');" href="javascript:void(0);">Login with Twitter ID</a> _IEAction(ABOVESOURCE, "Click") ;New window appears for Twitter sign in, but the URL is locked. ;Source: <input class="submit button selected" id="allow" type="submit" value="Authorize app"> _IEAttach($ie, ABOVEHANDLE) ;How do I get the handle of the new window from above? _IEAction(ABOVESOURCE, "Click") _IEAttach($ie, $originalHandle) EndFunc ;====================================================================== ;===Code=============================================================== login() ;======================================================================  
      Thank you in advance.

      Hello AutoIt community
      I run into speed problem in my script wich i cant solve myself, problem is with decoding texture loop - for better explanation, you need extract from file pallete (16x 16 RGB color) and picture data (224 * 128 byte), then use correct color for your picture data.... nothing extra hard and also texture is quite small 224*256
      it is for my car model viewer/later maybe editor GranTurismo 2 from Playstation 1, so its old dataformat and i cant understand why AutoIt take so long to decode texture when good old Playstation almost 2,5 decades old can do that nearly immediately (when you list through cars in shop or garage)
      My first atempt was create all trought dllstructure, because its easier approach, but it was soooo slow (40-50s for create textures) then i upgrade my routine via arrays, first 3D arrays later only 1D, next i put decoding colors outside loop but it is still not enough, my last version took cca 15s wich is still unacceptable for car model viewer when you click on one carmodel from listview (1100 cars for whole game) and you must wait 15-16s for model to load....  oh and i forgot mention some cars have more then 1 color (much more... 8-9-10 etc) soloading take 8-9-10 times more time
      in attachment i post texture file from GranTurismo 2 for one car (contain only 1 color) and also my dll struct version and array version code
      dll struct version - ± 40 sec (33 without saving)

      Hello all,
      I'm trying to create a webscrape script using AutoIt.  A non-profit I'm involved with is using GroupSpaces.com and there is no notification to the group when someone posts a new topic to the forum.  I'm including IE.au3

      #include <MsgBoxConstants.au3>
      #include <Array.au3>
      #include <String.au3>
      ; Open Groupspaces.com
      Global $oIE = _IECreate ("http://www.groupspaces.com")
      _IENavigate($oIE,"http://groupspaces.com/MyCrazyTest/forum/")
      ;Grab all the links on the Forum page
      Global $oLinksCategoryPage = _IELinkGetCollection($oIE)
      For $oLink In $oLinksCategoryPage
          Local $oLinkHRef = $oLink.href
          If StringInStr($oLinkHRef,"forum_id") Then
              ;This is a category. Click into it.
              _IENavigate($oIE,$oLinkHRef)
      Sleep(3)
              ;Back out to Category List
              _IEAction($oIE,"back")
          EndIf
      Next
      _IEQuit($oIE)

      Hi all,
       
      I was pondering over a question with regards to the speeds of reading something and did not see this kind of question in a forum search.
      The question: What is (technically) faster? Multiple reads from the same 3d array cell, or only once make a 'temp' variable from that cell and read the value from this? I don't know if either has any real impact at all anyway, but just wanted to ask anyway. :-)
       
      There may be a difference if the value holds an integer or a string (or something else) but in my case, is a simple integer.
      To hopefully clarify with a small bit of code:
      $process = $start - 15 If $xy[$process][3] <> "x" Then If _ArraySearch($open, $process, 1, $open[0][0], 0, 0, 1, 1) <> -1 Then UpdateOpen($xy[$process][5], $closed[0][0]) ElseIf $start > 0 And _ArraySearch($closed, $process, 1, $closed[0][0], 0, 0, 1, 0) = -1 Then Add_open($start, $closed[0][0], $counter, $process) EndIf EndIf You can read from this, that the array $closed[0][0] is being read 3 times. And this goes on further in the code I did not show.
      My question boils down to this, should I make a 'temp' variable to hold that $closed[0][0] value until the function is done?
       
      It may not have a real impact on my small script, but I really am interested in the answer at least.
       
      Regards,
      Tri.
