Re: [Guide] C++ DLL injection for Main Server

i started to read c++ this week.. (at home)

im still reading about:

#include <iostream>

int main()

using namespace std;

cout <<

return 0;

endl;

and what functions they have..

somethimes its very boring but i think when i know a bit more it will be much easyer to understand...

Re: [Guide] C++ DLL injection for Main Server

I would prefer if you would find a tutorial rather than asking here, it's not very related to the thread.

Also, I don't get a clue of what you're saying. Find a tutorial in your native language would do better.

Re: [Guide] C++ DLL injection for Main Server

Sorry for bumping an old thread, but seeing as it's not even on the second page, I'm not going to worry about it...

I'm trying to do this basically for fun, and to learn more C++.

I'm apparently calling something wrong, because when I start the main server with this DLL hooked, it throws an exception. I know it is this code, because when I take this out, it works. I tried simplifying the process (probably inefficiently because I suck at C++) and it still doesn't work.

void KalHook::ShowInfo(LPCSTR text)
    {
        DWORD infoAddress;
        

        infoAddress = 0x00432860; 
        
        __asm {
             push 1
             push text
             call infoAddress
             add esp,8

        }
    };

    void KalHook::Attach()
    {
	   this->ShowInfo("Hi");
    }

public:
        void Attach();
        void Detach();
        void ShowInfo(LPCSTR text);

If I've done something glaringly obvious, let me know. I really barely know this language.

I'm using VS 2005 Standard. The server can start okay as long as this code is not in the DLL.

Thanks.

Re: [Guide] C++ DLL injection for Main Server

ShowInfo = notice? xD
when not u forgot the color of the ShowInfo

Re: [Guide] C++ DLL injection for Main Server

I thought this was to put a message in the server console...?

What I did is took DeathArt's code and removed the color select parameter that specifies which color to use. Instead, I'm just specifying the function to call in asm. So I've actually simplified it, to no avail.

Any ideas? ><

Re: [Guide] C++ DLL injection for Main Server

u must use color lol

 

[DeathArt]

Re: [Guide] C++ DLL injection for Main Server

As BloodX said , the colour is a reqiure parameter.

Re: [Guide] C++ DLL injection for Main Server

I've been struggling with implementing the menu adding code TDA posted back on page 2. It seems to me I'm following the guide to the letter, but I could be messing up in the actual implementation ( or... copy / paste). How am I supposed go about it?

If anyone (including TDA?) would be willing to help me out on this, I'd very much appreciate it.

Re: [Guide] C++ DLL injection for Main Server

KalHooks.cpp:26

HWND hWnd = FindWindow(NULL,TEXT("MainSvr"));

You 100% sure your application have the correct title? It's finding it based on the name of the window (Taskbar / Title Frame).

Else you have to use Spy++ to find the HWND for it. But I think that changes for each start up.

I'm definitely not 100% sure. I had tried putting in something like "MainSvr on port 30001" (which matched the name of the window), in addition to putting in a string to match the title definition in MainConfig.txt.

Any suggestion as to what I should try? Thanks for helping out. :

By the way... I looked for you on MSN but I'm pretty sure you blocked me after I asked you a stupid question about SwordCrypt a little over a year ago.

Re: [Guide] C++ DLL injection for Main Server

We resolved the problem to a missing sleep() in Varis' code. I forgot to documentate that it's essencial, as the takes a few seconds before the stuff loads.

And a picture of my dev-enviroment for the lulz.

Anyone would care to share the FindPattern() function? Would save me some time.
Thanks.
