dll injection war3 - c++

Question

I have ths code:
__asm
{
PUSHAD
MOV EAX, DWORD PTR DS:[hStorm_LOBBYPTR]
TEST EAX, EAX
JE nick_false
MOV ECX, DWORD PTR DS:[EAX+0xC464]
TEST ECX, ECX
JE nick_false
MOV EAX, DWORD PTR DS:[ECX+0x170+0xB0]
TEST EAX, EAX
JE nick_false
MOV EDX, i
MOV ECX, DWORD PTR DS:[EAX+EDX*4]
MOV EAX, DWORD PTR DS:[ECX+0x1A0]
MOV ECX, DWORD PTR DS:[EAX+0x1E4]
MOV EAX, DWORD PTR DS:[ECX+0x1E4]
MOV ECX, DWORD PTR DS:[EAX+0x1E8]
MOV tempdw, ECX
POPAD
JMP nick_true
nick_false:
XOR EAX, EAX
MOV tempdw, EAX
POPAD
}
nick_true:
/* do check if tempdw is NULL and then proceed with your stuff */
How can I wrap it into DLL (Visual Studio C++ 2008)?
After that, I need to inject the DLL into some process and then retrieve tempdw, how can I do that?

Answer 1

you'll need to warp that in a normal C func, however, judging by the labels, it won't be a naked func:
void MyHook()
{
__asm
{
//asm here
}
nick_true:
//the other stuff
}
this then needs to be put into a basic dll project that writes the needed hooks using WriteProcessMemory (nothing more than that can be given as there isn't enough info).
To inject it, you can use RemoteDll or edit the launcher from w3l
