Intercept dll's loading (windows)

joaquimandrade · **Author**

Hello. I would like to know how to intercept dll's loading. Basically I would like to match a list of strings of names against each dll that loads and do operations in order to be able to use GetModuleInformation on them. I'm not seeking for instructions for hooking but for what should I hook. Sorry if it's not fully on topic.

Why not just use GetModuleHandle ?

Because I want to hook functions that happen when they initialize.

If loadlibrary is an import, detour that and check if it is loading the dll you're interested in.

What are you looking for specifically? If you just while(!handle) { handle = GetModuleHandle("silly.dll"); Sleep(10); }; You may be OK, unless you're looking for some stuff that gets called real early on.
