Hi everyone

I have 2 basic question about hex editing

- I have several texts with a common problem, in stead of having CRLF (carriage return+line feed) only had 0x0A (LF), how do I add 0D behind every 0x0A?

- Its possible to edit only the beginning of a file (speaking in large files that should't be loaded in memory) and save the changes?

Heroes, there is no such thing

One day I'll discover what IE.au3 has of special for so many users using it.
C'mon there's InetRead and WinHTTP, way better

Hi everyone

I have 2 basic question about hex editing

- I have several texts with a common problem, in stead of having CRLF (carriage return+line feed) only had 0x0A (LF), how do I add 0D behind every 0x0A?

- Its possible to edit only the beginning of a file (speaking in large files that should't be loaded in memory) and save the changes?

For the first question maybe? :

$string = "First Line 0x0A Another Line"
$replace_string = StringReplace($string, "0x0A", "0Dx0A")
MsgBox(0,"", "After: " & $string & @CRLF & "Before: " & $replace_string)

For second question give a look _FileWriteToLine function in the help file:

#include <File.au3>
;Example: Write to line 3 of c:\test.txt REPLACING line 3
_FileWriteToLine("c:\test.txt", 3, "my replacement for line 3", 1)
;Example: Write to line 3 of c:\test.txt NOT REPLACING line 3
_FileWriteToLine("c:\test.txt", 3, "my insertion", 0)

Hi!

thanks for te effort :)

in your first example it replaces all the data without check if a CR (0x0D) exists before a LF (0x0A), it only needs to and a CR behind a LF which doesn't has a CR already

for the second, in case of bynary file, it would work correctly :s

DiOgO,

I use this Regex to set every EOL possibility to @CRLF: ;)

#include <Array.au3>

$sText = "Line 1" & @CR & "Line 2" & @LF & "Line 3" & @CRLF & "Line 4" & @LF & "Line 5" & @CR & "Line 6" & @CRLF & "Line 8"

$aLines = StringSplit($sText, @CRLF, 1)
_ArrayDisplay($aLines, "Before")

$sText = StringRegExpReplace($sText, "((?<!\x0d)\x0a|\x0d(?!\x0a))", @CRLF)

$aLines = StringSplit($sText, @CRLF, 1)
_ArrayDisplay($aLines, "After")

It looks for @CR without a following @LF - and @LF without a leading @CR. I hope it helps. :)

not exactly, it is in hex code :)

yeah, but what means ?<! and ?! and why is a capture group inside a capture group? (like capturing it 2times xD

btw, you don't know how can a file be edited in a address (0x000024 and lenght 0x2A for i.e.,) and saved without having to copy to another location/file?

DiOgO,

yeah, but what means ?<! and ?! and why is a capture group inside a capture group? (like capturing it 2times

As I explained, the Regex looks ahead and behind to see if there is the other part of a @CRLF - in which case it does nothing. Let me try and explain:

Follow the numbers in order

(?<!\x0d)     - 2 - Look behind (the ?>! part) and make sure it is NOT preceded by @CR (0x0D)
\x0a        - 1 - Look for @LF (which is 0x0A) then 
|         - 3 - Or
\x0d        - 4 - We look for @CR and then
(?!\x0a)    - 5 - Look ahead (?!) and make sure it is NOT followed by @LF

The parts in () are non-capturing negative lookbehind/lookahead - and are well explained in my favourite Regex tutorial at http://www.regular-expressions.info/tutorial.html.

The whole thing needs to be in () so that it is a capturing group for the SRER to replace.

Any clearer? :D

      This topic give you access to an AutoIt functions library I maintain which is called PAL, Peter's AutoIt Library. The latest version 1.26 contains 214 functions divided into these topics:
      window, desktop and monitor GUI, mouse and color GUI controls including graphical buttons (jpg, png) logics and mathematics include constants string, xml string and file string dialogues and progress bars data lists: lists, stacks, shift registers and key maps (a.ka. dictionaries) miscellaneous: logging/debugging, process and system info Change log and files section  on the PAL website (SourceForge).
      A lot of these functions were created in the development of Peace, Peter's Equalizer APO Configuration Extension, which is a user interface for the system-wide audio driver called Equalizer APO.

      Hey guys!
      I just started working with the GUI yesterday and it has only brought more fun to the Autoit adventure  
      Basically I have a GUI windows that opens and based on the selection of the combo box the button will do something different. This specific scenario I am talking about the Client Update Verification  combo selection. When selected and the button is pressed my second gui window opens. As of now if I only paste comp1 or comp2 by itself it works correctly, but if I paste both, it has a fit.
      What would the correct way to do this be? Any help or examples, would be greatly appreciated! Thank you in advance

      Hi AutoIt programmers, excuse me for bothering you with multiple topics.

      In AutoIt we can use Number() function to convert Hex string to number but it's output is different of C# output & and i wanna make it's output like AutoIt code.

      For e.g I use this in AutoIt:
      Local $dBinary = Binary("Hello") ; Create binary data from a string. Local $dExtract = Number(BinaryMid($dBinary, 1, 5)) ConsoleWrite($dExtract & @CRLF) And i use this for C#:
      using System; using System.Text; //NameSpace Is Use of Project Name namespace TEST { class Program { public static void Main(string[] args) { //declaring a variable and assigning hex value string dd = ToHex("Hello", Encoding.ASCII); decimal d = Int64.Parse(dd, System.Globalization.NumberStyles.HexNumber); Console.WriteLine("Result: " + d); //hit ENTER to exit Console.ReadLine(); } public static string ToHex(string sInput, Encoding oEncoding, bool b0x_Prefix = false) { byte[] a_binaryOutput = oEncoding.GetBytes(sInput); string sOutput = BitConverter.ToString(a_binaryOutput).Replace("-", ""); if (b0x_Prefix == false) { return sOutput; } else { return "0x" + sOutput; } } } }
      I say once again that excuse me for creating new topic, in fact i'm making a library for GAuthOTP from a topic in AutoIt.

      I have a autoit exe file which is used in upload/browse file functionality.  This has been integrated with selenium framework and I am invoking the autoit exe using Java process and runtime. 
      Now the issue is when I run the scripts and invoke the autoit exe in local it works perfectly.  But when I use selenium grid or jenkins to run the scripts in another windows server it is not working.
      Can anyone please suggest any solution for this?
