Editing DLL's using AutoIt

[the_OG]

Hello again,

I am here to ask if it is possible to edit a DLL through AutoIt the way you can through a Hex Editor. Reason for my asking, is I am in need of a tool that will rewrite certain strings inside of a DLL to what the user defines. Any insight on this would be greatly appreciated!

FileRead() the dll file, and use StringInStr, or StringReplace() to find the bytes you want to edit...

Attached is an example of how I did it when I made a patch for msn messenger..

Edit:

Also, autoit is very much able to handle data much as hex editors do(hex editors show the data in hex), and autoit can convert data into hex with _StringToHex()

Example:

#include <String.au3>

$String = Chr(5) & "my binary string" & Chr(5)

$StringInHex = _StringToHex($String)

MsgBox(0, _HexToString($StringInHex), $StringInHex)

Edit:

Changed StringSplit() to StringReplace() - duh...

Edit2:

For anyone else reading this, note this:

The example I posted is very old lol, and might(is) not be a very good, or "clean" code:P
