I needed a way to HexEdit / Patch a file to repair a common file corruption problem in a software package my company uses. I first used the AutoIt core FileOpen / FileWrite functions but this method required me to open the whole file into memory. The files I work with can be several hundred megabytes in size and easily cause out of memory errors. So, After searching / hacking I came up with this solution.

I hope someone finds it useful :mellow:

#include <WinAPI.au3>

Func _Demo()
    Local Const $TestFile_Path = @ScriptDir & "\Test.Bin"
    Local $TestFile_ID, $bData, $Offset
   
    ;## Hex offsets / lengths of the data stored in the file.
        Local Const $Offset_Phone[2]    = [0x012,  4]
        Local Const $Offset_NewToy[2]   = [0x1b6, 18]
        Local Const $Offset_Recycle[2]  = [0x594, 24]

    ;## Binary string of the test file.
        Local Const $TestFile_Data = "0x" & _

Thank you Zinthose,

It's interesting ! It works very well ! :mellow:

My projects : GCS Search 1.07 (GUI Control Styles Search)* Multilingual tool to help about the old scripts, with a dynamic menu.* Easy way to find missing Include files in old scripts downloaded from forums !* Famous Monoceres script added and improved (visual, drag and drop, automatic)* There is an interactive color converter with palettes too, for fun !The best way to start Autoit3 development (for newbies).

:mellow: I'm humbled, but isn't that the point witting code? So the next guy, including yourself can make sence if it?

In this case yes, but it's not very common; appropriate and descriptive comments is quite rare. Yes I know what a message box does, no I don't know what this dllstruct is used for. :(

Don't bother, It's inside your monitor!------GUISetOnEvent should behave more like HotKeySet()

I needed a way to HexEdit / Patch a file to repair a common file corruption problem is a software package my company uses. I first used the AutoIt core FileOpen/FileWrite functions but ran this method required me to open the whole file into memory. And the files I work with can be several hundred megabytes in size.

You will need to know your way around a hex editor and be prepared to perform some file comparisons before and after a change to identify were the file change hex offsets are.

Hex editing is more art than science IMO. You just need to get a free hex editor, backup your files, and work the proverbial clay until it just clicks. If you do a Google search you might find a hex editor tutorial.

Anyway, Teaching binary file manipulations are probably out of the scope of the AutoIt forums.

Wel i m using hackman 9 as hex editor. my quention is that is it possible to search any binary bytes if you don't know the offset, bcoz i want to search some bytes in random files. so i can't be sure about its offset.

So you want an additional function to search a binary file and return the Offset if the value is found?

Func _HexSearch($FilePath, $BinaryValue, $StartOffset = Default)
    ;## Perform Magic
        Return Aberacadabera()
EndFunc

EDIT: I created the _HexSearch function and added it to the original post. :mellow:

it works, thanx, all i need now is to convert hex to text.

nvm:

$data = _HexRead('chai_4-3.zip.torrent', '369', '20') ; 20 is the lenght of the output

$data = StringTrimLeft($data,2)

$data = _HexToString($data)
ConsoleWrite($data & @CRLF)

Question, Hex edit function does not work. What im doing wrong?

I have a file 50 4D 56 D2

Now I want to replace D2 With DE

I do this and nothing happens.

$result =  _HexWrite('sample.txt', 3, 'DE')

ConsoleWrite($result & @CRLF)

EDIT Never mind:

it works this way:

$_HexRead   = _HexRead('autosave.pmv', 3, 2)
    ConsoleWrite($_HexRead & @CRLF)

    $result =  _HexWrite('Riddle.pmv', 3, $_HexRead)

For other newbies like me... On the _HexRead(file,offset,length) function... To actually get the 'offset' rather than the pointer, convert the offset to dec before parsing it through that function...

_HexRead($File,Dec($Offset),$Length)

I'm a complete newbie with Hex stuff, so it took me a few mins to figure it out... ;)
