[Hooking] Inject Into a Running Process, by: Sinner

I like my injector to inject into a running process, it means the injector can work in a background thread and inject whenever the user starts the game from anywhere (ie ASE).

So here's my injection code:

CODE

BOOL InjectIntoProcess(TCHAR* szExeName, TCHAR* szDllName)



{



        TCHAR szProcessName[MAX_PATH];



        TCHAR szDllNameAndPath[MAX_PATH];



        DWORD aProcesses[1024], cb, cProcesses;



        HANDLE hProcess = NULL;



        HMODULE hMod = NULL;



        UINT i = 0;



        // Get the full path to the DLL for later use 



        GetCurrentDirectory(MAX_PATH, szDllNameAndPath);



        wcscat(szDllNameAndPath, _T("\\"));



        wcscat(szDllNameAndPath, szDllName);



        // Get the list of process identifiers 



        if(!EnumProcesses(aProcesses, sizeof(aProcesses), &cb)) 



                return FALSE;



        // Calculate how many process identifiers were returned 



        cProcesses = cb / sizeof(DWORD);



        // Get the name and process identifier for each process 



        for(i = 0; i < cProcesses; i++)



        {



                hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, aProcesses[i]);



                if(hProcess)



                {



                        if(EnumProcessModules(hProcess, &hMod, sizeof(hMod), &cb))



                        {



                                GetModuleBaseNameW(hProcess, hMod, szProcessName, sizeof(szProcessName)/sizeof(TCHAR));



                        }



                        if(wcscmp(wcslwr(szProcessName), szExeName) == 0)



                        {



                                // We found the process, inject our DLL 



                                if(DetourContinueProcessWithDllW(hProcess, szDllNameAndPath))



                                {



                                        return TRUE;



                                }



                        }



                }



                



                CloseHandle(hProcess);



        }



        return FALSE;



}

Now we can inject a DLL as easily as this:

CODE

   if(InjectIntoProcess(_T("et.exe"), _T("hax.dll")))



        {



                _tprintf(_T("Injection successful!\n"));



        }



        else {



                _tprintf(_T("Injection failed.\n"));



        }

And you can use a loop to check when to inject.
