I've noticed that for the task of "reading a file row by row into an array" FileReadToArray is consistently slower than a FileRead + StringSplit.
The following script:
Results in the following output for me:
And the output with switched call sequence:
This surprises me, since I first assume that the native function offers more optimization possibilities than having to create an array in AutoIt via an intermediate string.
So I thought that maybe FileReadToArray is more economical with memory. But again FileReadToArray seems to consume more memory than the StringSplit variant. For this I got the PeakWorkingSetSize after the call of the respective function.
After FileReadToArray the Size is always higher than with StringSplit. Since this is not the case if one changes the order of the two functions (see above), one can assume that FileReadToArray actually has this difference. The difference is mostly the double file size. Which would make sense if the file is completely saved internally as a UTF-16 string.
Can anyone explain to me why FileReadToArray performs so unexpectedly poor - or am I missing something?

Hello all
A programme I wrote for the organisation for which I work has been in use for a number of years with no issue. One of the things that it does is allow for attachments to be selected (Word docs, Excel sheets, etc) which it then writes away as a BLOB in MySQL.
This was all working fine until recently, when suddenly, on the odd occasion, Word would advise that the file was corrupt on retrieval of the BLOB from MySQL.
Upon further examination it appears that the issue is not with the retrieval of the data from MySQL, but reading in the data from the disk by AutoIT. It seems that on occasions that AutoIT will only read half the file.
I have no idea why this is, as the whole function is very simple. I have included a sanitised vesion of it below in the hope that someone can tell me where to look next, as this one has me beat (again). 😋
I have put some comments in to show what I have done to try and solve the problem, but am getting no closer to the truth. @error is the strangest one - it should return -1 when it reaches end of file but is returning zero.
Func _AttachAttachment() local $file,$chars,$fsize If $RFC_Retrieved = False Then msgbox(0,"Error","Must have a RFC active first") Else $file=FileOpenDialog("Attach to RFC",".","All (*.*)",1) ; Check if file opened for reading OK If $file = -1 Then MsgBox(0, "Error", "Unable to open file.") Exit EndIf ; FileClose($file) These two lines are my attempt to open the file in binary mode. Made no difference ; FileOpen($file,16) ; Read in the File $fsize = FileGetSize($file) ConsoleWrite("File size is " & $fsize & @CRLF) ; the size comes back as what it say in Windows properties ; $chars = FileRead($file,$fsize) ; I was using this, then tried the line following this. It didn't help $chars = FileRead($file) ; This is showing a figure $chars/2 - 1 I don't understand this ConsoleWrite("Number of chars read is " & @extended & " error code is " & @error & @crlf) ; @error is coming back with 0. I don't understand this as I thought it would be -1 FileClose($file) EndIf EndIf EndFunc Thanks in advance for looking at this

Hello,
I need to pull data from company intranet website. I created a script that I can give a list of project numbers and it will open up the the related webpage for each project, save the html comments for that project, then move on to the next.
However my problem comes in that each time I open up a project it locks it for other users, and if you just exit the page it keeps it locked, you have to actually press the "close" button on the page. So I'm not sure how to deal with this as I end up just locking every project in my name when I run my program as I don't understand the nature of how the website is built. I don't understand how to close with just using my automation code without manually having to press the stupid button.
My Function:
Func Getscript($ProjectAddress) ;getting the page source code and storing it into text file for easy reading it $file = FileOpen(@ScriptDir & "\source.txt", 10) $IE = _IECreate($ProjectAddress & ".html", 0, 0) $source = _IEDocReadHTML($IE) FileWrite($file, $source) $target_source = _StringBetween($source, "<BODY>", "</BODY>") ; only take content between the specified tags _IEQuit($IE) FileClose($file) return $target_source[0] EndFunc ;==>Getscript
Source Code I got from website that I think is relevant:
function closeForm(){ if(topButtonEnabled("closeButton")){ parent.mainFrame.closeForm(); } } <button id="closeButton" class="saveCloseButton" style="LEFT: 77px;" onclick=closeForm()> Close </button>
Any Ideas of how to tell website to either activate the closeform function or just give it the command to close?
Thanks

Junior Programmer here...
Not much experience with opening, changing and closing files.
I am trying to replace strings in a Text file except StringReplace does not actually replace the text.
Here is a sample of my code...
#include <File.au3> #include <MsgBoxConstants.au3> #include <WinAPIFiles.au3> Local $iStrReturn = 0 Local $hFile Local $sText Local $sNewText ; Location of File to be read $sFileName = "C:\Temp\MyPlayer.exe.config" ; The default is FALSE. We want to change this to TRUE $bLoopChecked = True CheckBox() Func Checkbox() $hFile = FileOpen($sFileName,$FO_READ) ; Open file in read mode to get text If $hFile = -1 Then MsgBox($MB_SYSTEMMODAL, "", "An error occurred when Opening the file.") Exit EndIf FileSetPos($hFile, 0, 0) ; No idea if I need to do this, grasping at straws $sText = FileRead($hFile) ; Read the file into $sText If $sText = 1 Then MsgBox($MB_SYSTEMMODAL, "", "An error occurred when reading/writing the file.") Exit Else FileClose($hFile) ; Finished reading the file into $sText, so close the file. FileFlush($hFile) ; Manual says to use FileFlush between File Close and Open so here it is EndIf MsgBox(0,"Before Replacement",$sText) ; Displays the text read from the file to make sure something is there. ; Loop Check If $bLoopChecked = True Then ; Find the string return > 0 for success $iStrReturn = StringInStr('"<add key="LoopCheckbox" value=""False" />"', "False") ;MsgBox(0,"", "LoopCheckBox is " & $iStrReturn) If $iStrReturn > 0 Then ; If StringInStr returned > 0 the it found the string! ; The Meat of the code. This is where we have to replace "False" with "True" $sNewText = StringReplace($sText, '"<add key="LoopCheckbox" value="False" />"', '"<add key="LoopCheckbox" value="True" />"') MsgBox(0,"After Replacement",$sNewText) ; Display the text to see if it worked. $hFile = FileOpen($sFileName,$FO_OVERWRITE) ; Reopen the file to write to it, overwriting everything. FileWrite($hFile,$sNewText) ; Write the text to the file FileClose($hFile) ; Close the file EndIf EndIf EndFunc This is the file I am reading...
<?xml version="1.0" encoding="utf-8"?> <configuration> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6"/> </startup> <appSettings> <add key="LoopCheckbox" value="false"/> </appSettings> </configuration> I tried opening the file with $FO_UTF8 and $FO_UTF8_NOBOM but got errors opening the file.
The MsgBox "After Replacement" shows the value is still false.

Is it possible , and how can I read and write txt files from Icloud (apple service) ?
Let me try to explain my application.
On my Ipad and Iphone I create txt files. On my windows computer it is possible to read and modify these files manually, by logging in on www.icloud.com.
What I want to make is an auto-it script who reads the txt file and create an new txt file on www.icloud.com, so I can acces these on my ipad and/or phone.
Thank you.
