Hy guys, sorry for bad english but i'm Italian Sad

.
I wonder if you can help me with a program. I want the program protect a process from dll-injection.
I thought to scan every module of the "victim-process" for find out if an unauthorized dll could be found, but it's to much specific! I found an example of function interception created by a code-project user but the code is written in "C" while i program in vb 2010.

If you guys can help me with the code written in "C" or you have another ideas for protect a process from dll.injection, would be great!.

Additional information:
- I don't have the source code of the "victim-process".
- The "victim-process" is a game. (metin2-p.server)
- I'm not really good so if you can explain in detail your ideas or if you can post an example code, would be appreciated.

P.S: Here the link of the project of function interception: codeproject#com@Articles@5178@DLL-Injection-and-function-interception-tutorial (replace @ with "/" and # with ".", dot)

Do you have the sourcecode of the server? If so,you could apply encryption to the protocol, and run the client by your own launcher that hooks winsock and handle the encryption there. That way people will have to use your anti hack tool

If not, you're screwed and people can just get an unmodified client.

With crc he means an integrity check. (pretty easy to bypass though)

Dark Byte there is an option on the server side that negate the access to the server from other launchers. I only need protection on client side for negate dll-injection..
I prefer if you consider only what i said at start. I need an example code that i will analyze by myself after for protect a process from dll injection. I don't care about the way but i want it. I've been looking for it for a long time. I have some ways to take for do it but they are too much hard for me. If you post some way to take in alternative at mines, more easy with an example code which i will analyze after maybe with some comment for explain the code would be appreciated. Or it can be hard i don't care but post the code i will study it with the help of msdn.

However thanks for answer.

you can set a hook on functions needed for dll injection (writeprocessmemory, virtualqueryex) before the initialization of your game.
