Patching an offset?

[Codefuser]

Any ideas on how I can patch an offset of an external file from AutoIt? I want to figure out to overwrite that offset with random data.

FileSetPos?

So something like

$file = FileOpen("file.exe",1)

FileSetPos($file, "0x45FFF", 0)

But then how many characters are in an offset?

What is the purpose of your script and please don't come back with an answer that you want to write binary data to an EXE, but rather explain what and why you want to do this?

It is to patch a few bytes in UPX-ed executables to make it slightly harder to unpack.

Good luck with that. Just read the file binary, change the position and write it back to the file.
The helpfile is your friend. When you have issues making it work just post the code you have so we can see what is wrong.
