DLL injection...?

Yo, me again.

I havn't made a DLL in such a long time now, and I wanted to try and make a hack now but i'm having some troubles.

I'm using Dev C++.

Code:

#include <windows.h>   

BOOL APIENTRY DllMain (HINSTANCE hInst     ,
                       DWORD reason        ,
                       LPVOID reserved     )
{
    switch (reason)
    {
      case DLL_PROCESS_ATTACH:
           MessageBox(NULL,"Test","Test",MB_OK);
        break;

      case DLL_PROCESS_DETACH:
        break;

      case DLL_THREAD_ATTACH:
        break;

      case DLL_THREAD_DETACH:
        break;
    }
    return TRUE;
}

I'm testing this on Minesweeper, i'm using Valkyrie injector. It's just supposed to open a messagebox when it's injected but nothing comes up when it's injected. I can't even find any problems with this.

All help appreciated, thanks.

Try placing it in DLL_THREAD_ATTACH, see if that works. is Valkyrie a stealth injector(does it remove your DLL from the PEB linked list etc?)

try using another injector(google for TatniumInjector or s1nject)

Tryed that already.

I can't find those injectors, no other injector will work for this?
Or are you just suggesting those?

Ummm... I think you have to inject it while the executable is loading, but not sure. Lately I've been failing so I won't say to much. =/

I dunno, any DLL i've ever written can be injected any time.

I used MSVC++'s DLL template thing and now it works fine.

When you create a DLL project in MSVC++ it gives you kind of like a base DLL skeleton to work with. That's what I meant.

would you be able to share the injection code , the samples i try dont work for some reason

this is the sample , http://www.dreamincode.net/code/snippet407.htm

That isn't a DLL, that's a DLL injector.

Well... tell us what the problem was.

Bleh, I just switched computers, I don't have anything on this. It's not even Windows.
I'll update you on that tomorrow.
