hey i would like to ask is this the way to use SetThreadAffinityMask in first core? Thanks
void start()
uint64_t threadId = (uint64_t)GetCurrentThreadId();
HANDLE handle = OpenThread(THREAD_ALL_ACCESS, false, threadId);
SetThreadAffinityMask(&handle, 0x01);
for (;;) {
Xtimer MyRdtscTimer;
MyRdtscTimer.Delay(1000000000);
}

i tried GetCurrentThread but seems not working in my end

I made in C++, DLL Injector and DLL file which one will be inject to process.
But how can I test my injector correct inject my dll file? Is possible send some logs from DLL file after inject to process?
Process and DLL file is 32bit.
There are probably better way but a message box and beep is provably sufficient
BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
hInstance = hModule;
DisableThreadLibraryCalls(hModule); //disable unwanted thread notifications to reduce overhead
//CreateThread(NULL, NULL, Engine, NULL, NULL, NULL);
_beginthreadex(NULL, NULL, Engine, NULL, NULL, NULL);
Beep(750, 500);
MessageBox(NULL, "Hello!!\r\nInjected", "Injected", MB_OK);
//MessageBox(NULL, L"Hello!!\r\nInjected", L"Injected", MB_OK); //unicode
break; //break attach
case DLL_PROCESS_DETACH:
break;
}
return true;
}
How I will be able to create a native dll that I can execute with rundll32.exe without specifying an entry point:
Example :
C: \> rundll32.exe mydll.dll
I created a DLL project on visual studio but I don't know where to put my code:
DLL project template generated by Visual Studio
// dllmain.cpp : Définit le point d'entrée de l'application DLL.
#include "pch.h"
BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
my code that I want to run with the dll :
#include <stdio.h>
#include <stdlib.h>
// enable cross compiling
#ifdef __linux__
#include <sys/mman.h>
#elif _WIN32 || _MINGW_
#include <windows.h>
#endif

The entry point parameter of rundll32 is not optional, you MUST specify an entry point, otherwise rundll32 won't know which function to call. There is no "default" entry point.
To be callable by rundll32, you must export a function with one of the following signatures:
void CALLBACK EntryPoint(HWND hwnd, HINSTANCE hinst, LPSTR pszCmdLine, int nCmdShow)
void CALLBACK EntryPointA(HWND hwnd, HINSTANCE hinst, LPSTR pszCmdLine, int nCmdShow)
void CALLBACK EntryPointW(HWND hwnd, HINSTANCE hinst, LPWSTR pszCmdLine, int nCmdShow)
For example:
#include "pch.h"
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved

And just FYI, you don't actually need the worker thread at all, you can just execute the shell code directly like any other function:

I am writing a simple dll hook to draw on a program, to do this I inject the dll into the process, which than creates a thread where it retrieved the endScene location. In order to retrieve the end scene location, I found the address of "Direct3DCreate9", which I than used to find the vtable. My problem is, Calling the Direct3DCreate9 seems to be crashing the program instantly.
My code is the following, is there something wrong with how I get the Direct3DCreate9 location or something else about it?
DWORD WINAPI MainThread(LPVOID param) {
// Information
HMODULE module = GetModuleHandleA("d3d9");
//d3d = Direct3DCreate9(D3D_SDK_VERSION); // create the Direct3D interface
// Find adress of create
LPDIRECT3D9(__stdcall*pDirect3DCreate9)(UINT) = (LPDIRECT3D9(__stdcall*)(UINT))GetProcAddress( module, "Direct3DCreate9");
// Create the direct3d
LPDIRECT3D9 pD3D = pDirect3DCreate9(D3D_SDK_VERSION);
// Create IDirect3DDevice9 and destroy
D3DDISPLAYMODE d3ddm;
HRESULT hRes = pD3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3ddm);
D3DPRESENT_PARAMETERS d3dpp;
ZeroMemory(&d3dpp, sizeof(d3dpp));
d3dpp.Windowed = true;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.BackBufferFormat = d3ddm.Format;
IDirect3DDevice9 * ppReturnedDeviceInterface; // interface IDirect3DDevice9 (pointer to array of pointers)
// Set the window to program window
HWND window = FindWindowA(NULL, "test");
// Create it
hRes = pD3D->CreateDevice(D3DADAPTER_DEFAULT,
D3DDEVTYPE_HAL,
window,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
&d3dpp,
&ppReturnedDeviceInterface);
pD3D->Release();
DestroyWindow(window);
unsigned long* pInterface = (unsigned long*)*((unsigned long*)ppReturnedDeviceInterface);
DWORD endScene = (DWORD)pInterface[42];
// Output information to log file
std::fstream test;
test.open("log.txt", std::ios::out);
test << endScene;
test.close();
FreeLibraryAndExitThread((HMODULE)param, 0);
return (0);

I am trying to hook win32 API function "CreateFile" using MS Detours, but when I test it by opening a *.doc file using MS Word, The CreateFile call for DLLs and font files and directories loaded by MS Word are redirected to my detoured function but not for that *.doc file, but when I open a *.txt file using notepad the CreateFile call for that *.txt file comes to my detoured function.
I am using following code for hooking CreateFile:
static HANDLE (WINAPI *Real_CreateFile)(LPCWSTR lpFileName, DWORD dwDesiredAccess, DWORD dwShareMode, LPSECURITY_ATTRIBUTES lpSecurityAttributes, DWORD dwCreationDisposition, DWORD dwFlagsAndAttributes, HANDLE hTemplateFile) = CreateFile;
HANDLE WINAPI Routed_CreateFile(LPCWSTR lpFileName, DWORD dwDesiredAccess, DWORD dwShareMode, LPSECURITY_ATTRIBUTES lpSecurityAttributes, DWORD dwCreationDisposition, DWORD dwFlagsAndAttributes, HANDLE hTemplateFile)
{
OutputDebugString(lpFileName);
return Real_CreateFile(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile);
}
BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved )
{
LONG Error;
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
OutputDebugString(L"Attaching MyDLL.dll");
OutputDebugString(strInfo);
DetourRestoreAfterWith();
DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourAttach(&(PVOID&)Real_CreateFile, Routed_CreateFile);
Error = DetourTransactionCommit();
if (Error == NO_ERROR)
OutputDebugString(L"Hooked Success");
else
OutputDebugString(L"Hook Error");
break;
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
OutputDebugString(L"De-Attaching MyDLL.dll");
DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourDetach(&(PVOID&)Real_CreateFile, Routed_CreateFile);
Error = DetourTransactionCommit();
if (Error == NO_ERROR)
OutputDebugString(L"Un-Hooked Success");
else
OutputDebugString(L"Un-Hook Error");
break;
}
return TRUE;
}
Thanks in advance.
I think you are missing a break after this:
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
break; // Not interested in thread messages
case DLL_PROCESS_DETACH:
Are you just detaching the detour before it is called? Maybe opening a .doc creates a new thread but a .txt doesn't, triggering this code path.
It looks like you're not initializing your Real_CreateFile function pointer properly. I'm guessing you're setting it to your module's import table entry for CreateFile.
Instead, initialize it to GetProcAddress(GetModuleHandle("kernel32"),"CreateFileW");
Well I have made my proxydll for d3d9, the dll itself works and I can confirm it loads into the process because a yellow rectangle is created.
The problem is that I call SetTimer but my callback isn't called, what to do?
I can hear the two MessageBeep sounds but then none and my money in game stays 0.
this is my code:
// global variables
#pragma data_seg (".d3d9_shared")
myIDirect3DDevice9* gl_pmyIDirect3DDevice9;
myIDirect3D9* gl_pmyIDirect3D9;

{
case DLL_PROCESS_ATTACH: InitInstance(hModule); break;
