Zinthose Posted November 18, 2008 Posted November 18, 2008 (edited) 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 expandcollapse popup#include <WinAPI.au3> _Demo() Func _Demo() Local Const $TestFile_Path = @ScriptDir & "\Test.Bin" Local $TestFile_ID, $bData, $Offset ;## Hex offsets / lengths of the data stored in the file.

Jikoo Posted November 20, 2008 Posted November 20, 2008 Thank you Zinthose, It's interesting ! It works very well ! 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).

Zinthose Posted November 20, 2008 Author Posted November 20, 2008 You have an interesting coding style, it is very readable. I'm humbled, but isn't that the point witting code? So the next guy, including yourself can make sence if it? mLipok 1 --- TTFN
WeMartiansAreFriendly Posted November 20, 2008 Posted November 20, 2008 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()

Zinthose Posted November 21, 2008 Author Posted November 21, 2008 Your Script is Quite usefull can you tell me if i have some binary data but don't have its offset then how can i creat its offset ?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. --- TTFN

BinaryBrother Posted January 5, 2010 Posted January 5, 2010 (edited) 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...
