Calling Dll's with lua.

[vondarkness]

Hi everyone,
so like it's said in the title, I want to call a dll (C) with my addon.
I've found a way to do it using Alien lib, wich allows me to call win32 functions. It works but as soon as I try it with my addon, it doesn't work anymore.

It seems that the lua "require" doesn't work with addons.

require "alien" 
		local fw = alien.User32.FindWindowA
		fw:types{ret="long",abi="stdcall","string","string"}

I know that wow's lua engine is "sandboxed" but is there a way to make it work ?
(sorry for my english and I hope I didn't post it in the wrong section)

Afaik what you're trying to do is not possible without modifying/hooking WoW. Are you willing to do that? If not, then this thread doesn't even belong in this section.

If I was a Blizzard employee responsible for the addon interface in WoW, and if I had spent countless hours on safeproofing it from ever calling anything native or even respective LUA wrappers, this thread would make me *sigh*

Haha. If I were a Blizzard employee this entire forum section would probably make me *sigh*.

I didn't expect it to work, ofc blizzard doesn't want us to do this but thanks for answering.
@Cypher That's what I want to do (and i know how to do it), the only thing is , I just don't know which function hook.
w/e , I think I'm not going to do it, because the program which will hook could also be the one that calls the functions (in this case).
Anyways, thanks for answering me.

The easiest way to achieve this is to inject a dll and register an "interface" LUA function through which communications between LUA and your dll are established.
