Yes, I know guinness improved the ReplaceStringInFile function in terms of speed and  efficiency but hear me out. I made some changes to the original myself that increased the speed of the writing and more importantly for me change the occurrence option so the function would only replace that specific occurrence of string.

I not saying use my code. What I am suggesting is to add extra functionally to the ReplaceStringInFile so there is a option to replace a specific occurrence.

I could not think of a way to do this with the new one guinness made so above is just an example of how I did it with the old one.

I have also attached the file.au3 file.

Looking at the the code you assume every line ends with the same EOL character and then when you come to write the data to the file you just use a linefeed character. As for adding your suggestion, I don't feel it appeals to the wider audience. Thanks.

      Hello.
      I'm too stupid to see my mistake:
      To investigate the internal "dictionary" of TIFF files I'd like to read in the files in binary mode and to check, if there are more than one pages "in" this TIFF.
      Notepad++, "View as Hex" is presenting the first bytes as "49 49 2a 20 08 20 20 20 12" for the TIF attached to this posting
      The "TIFF Header Format" is easy:
      Offset 00h, 2 Byte = Byte Order, "II"=intel, "MM"=motorola. (I = 0x49)
      --> II
      Offset 02h, 2 Byte = Version Nr.
      Offset 04h, 4 Byte = pointer to first IFD entry
      Description of TIFF header: https://www.awaresystems.be/imaging/tiff/faq.html#q3
       

      Howto read and analyse the binary content correctly? This is my messy, not operational code:
       
      $sampleTiff="H:\daten\tif\11\11\111111.TIF" $h=FileOpen($sampleTiff,16) $content=FileRead($h) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $content = ' & $content & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console FileClose($h) $type=VarGetType($content) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $type = ' & $type & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $ToString=BinaryToString($content) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $ToString = ' & $ToString & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console ConsoleWrite(@CRLF & @CRLF) $content=StringTrimLeft($content,2) ; cut off the leading "0x" ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $content = ' & $content & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console for $i = 1 to 8 step 8 $next=StringMid($content,$i,2) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $next = ' & $next & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console $Chr=BinaryToString($next) ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $Chr = ' & $Chr & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console ConsoleWrite(@CRLF & "---" & @CRLF) Next Regards, Rudi.

      i'm trying to create a program that let's the user type a word in an input field (gui) and when a button is pressed the letters of the word are replaced by 1 word each from a list of words in a text file
      i created the gui for it but i need help to add some more code to make it work like intented

      each letter of a word should be replaced by a word from a text file
      the text file is a source for replacing letters is a file with 2 columns separated by tab that contains the entire alphabet (26 rows)
       
      please help if possible

      Hi all,
      I got this code and would like to be able to change Baud Rate and instead of sending character by character i would like to be able (if possible) to send whole string. But i don't know how to change it.
      I am taking input from file and processing whole line (this is done in FilesHandling.au3).
      To execute this i am just calling SendData("FileName", int) in "main" script.
      Any help very appreciated.
      #include <WinAPI.au3> #include <Array.au3> #include "FilesHandling.au3" ;init DLL function, we need handle to call the function $h = DllCall("Kernel32.dll", "hwnd", "CreateFile", "str", "\\.\COM19", "int", BitOR($GENERIC_READ,$GENERIC_WRITE), "int", 0, "ptr", 0, "int", $OPEN_EXISTING, "int", $FILE_ATTRIBUTE_NORMAL, "int", 0) $handle=$h[0] Func SendData($FileName, $LineNumber) ;string to be send $c = readFile($FileName, $LineNumber) $cLenght = StringLen($c) $aArray = StringSplit($c, "") ;_ArrayDisplay($aArray, "", Default, 64) For $i = 1 To $cLenght writeChar($handle, $aArray[$i], $cLenght) Next ;move to next line writeChar($handle, @CR,1) EndFunc ;write a single char func writeChar($handle,$c,) $stString = DLLStructCreate("char str") $lpNumberOfBytesWritten = 0 DllStructSetData($stString, 1, $c) $res = _WinAPI_WriteFile($handle, DllStructGetPtr($stString, "str"), 1,$lpNumberOfBytesWritten) if ($res<>true) then ConsoleWrite ( _WinAPI_GetLastErrorMessage() & @LF) EndIf EndFunc
