need help with hex editing in autoit.

[Proph]

I remember a while back Larry had created some functions that made hex editing possible. But they don't seem to work anymore because FileRead and FileWrite do binary editing (which is great). I can't seem to edit a file using hex anymore though. I was wondering if someone can kind of show me how it is done. I want to create a function called HexEditFile.

Basically I would tell it what file to edit, the position to look in the file, the Hex code to find, and the Hex Code to replace it with.

Like:

HexEditFile($MyFile, "ECE9", "28A8", "27AA")

Or something simular.

If someone can throw together a quick example to at least get me started I would appreciate it.

Thanks!
