Inicio in this case is just a reference point, where the dll procedure will start to load. You could name it however you want. Ex: Start. It can be written right below where you wrote your dll name.
You can get the GetProcAddress by doing the same than with LoadLibraryA. (Press Ctrl+N and write it down)

According to that guide, it would look something like this:

The guide above (lordbilly's) is for hooking a procedure DLL to a GameServer. I'm not sure in Step 11, it says JE and not JMP.

I think the difference tween guides is just the checking. But this guide should work perfect.

Thanks Hacke for your work and time.

Can anyone make a video guide?

Hi,
is there any chance, someone of You could help me with my main?
http://rapidshare.com/files/312358514/Main.exe.html

I tried about 1 week to hook dll by myself but i failed :/
Antihack.dll should have 11kb only? becouse when i try to compile it, it does with some warnings and i dont know why becouse i dont change anything in project.

and when i hook the dll i think i do everything good in ollydbg but dont know to which offset i need to change entry point in PE.
Anyone who could help me with explanations or just hook dll to main?

I`ll appreciate both becouse my server need to be run soon and i want to know for the future how to hook dll`s...
