I think hook windows DWM, but I can't find DirectX related dynamic library in DWM. DirectX exists in dwmcore.dll loaded by DWM. What can I do to use this library
the kiero::bind(..) function is defined as follow:
void kiero::bind(uint16_t _index, void* _original, void* _function)
{
// TODO: Need own detour function
#ifdef KIERO_USE_MINHOOK
if (g_renderType > 0)
{
MH_CreateHook((void*)g_methodsTable[_index], _function, &_original);
MH_EnableHook((void*)g_methodsTable[_index]);
}
#endif
}
but it just change the Formal parameters instead of actual parameters.
so the call like kiero::bind(42, oEndScene, hkEndScene) do not work and can casue process crash.
I change it as follow:
//void kiero::bind(uint16_t _index, void* _original, void* _function)
void kiero::bind(uint16_t _index, void** _original, void* _function)
{
// TODO: Need own detour function
#ifdef KIERO_USE_MINHOOK
if (g_renderType > 0)
{
//MH_CreateHook((void*)g_methodsTable[_index], _function, &_original);
MH_CreateHook((void*)g_methodsTable[_index], _function, _original);
MH_EnableHook((void*)g_methodsTable[_index]);
}
#endif
}
and the call kiero::bind(42, (void**)&g_oEndScene, hkEndScene) works well.
First of all thank you very much for your library. I use to do the same around ~6-8 years ago and forgot most of it, writing my own base seems overkill for my tiny project, so I happily use yours.
It works as expected and had a nice start, however I just found out that it spikes my GPU usage up to 25% higher than without the hook. Currently I'm trying to figure out why because I've never experienced it before.
Back then I've used a Findpattern/Detours way for CS:Source, and the detour functions used to be rather small. Looking into Minhook I see a lot of instructions there.
So my current guess lies on Minhook. But I would also expect I did something really wrong.
I've tested it out on this sample Dx11 application:
https://www.3dgep.com/introduction-to-directx-11/ (Binary on the bottom)
And to save time, used this injector:
https://github.com/DarthTon/Xenos/
Running the application results in a typical usage of ~38-41% CPU / ~50-52% GPU on a i5-4690/1080GTX.
With a running hook that just calls back the original function I have a result of around:
40-43% CPU (which is neglible) and up to 78% GPU.
I've removed most of my own code out of my sample:
https://pastebin.com/bq4YnJH9
I've found out that switching from __stdcall to __fastcall seems to improve performance just a bit, Compiling in release mode does not.
I'm currently tinkering with a different hooking mechanism and different types of diagnostic. Time to open up IDA again.
But maybe you have some input on how to improve the performance. Maybe me guesses are plain wrong. I wouldn't be surprised at all.
Thanks in advance!
/Edit:
After switching the library to Detours 4.0 (https://github.com/microsoft/Detours) I was able to bring the CPU back down to constant 38%, the GPU now stays pretty smooth at ~66% so that's something.
Still don't understand the problem at all. It's not like your library mines Bitcoin. I seem to miss something very fundamental.
hi mate really nice project sorry to write this here, but can I have your discord id to offer freelance projects? or if you can add me on discord : lifesoulmmkiy#6045
thank you and sorry again to write this here.
Hey yall, when trying to use the example code i keep getting
LNK2001 Unresolved External Symbol ""enum kiero::Status::Enum __cdecl kiero::init(enum kiero::RenderType::Enum)" (?init@kiero@@YA?AW4Enum@Status@1@W42RenderType@1@@Z)"
LNK2001 Unresolved External Symbol ""enum kiero::Status::Enum __cdecl kiero::bind(unsigned short,void * *,void *)" (?bind@kiero@@YA?AW4Enum@Status@1@GPEAPEAXPEAX@Z)"
LNK2001 Unresolved External Symbol ""unsigned __int64 * __cdecl kiero::getMethodsTable(void)" (?getMethodsTable@kiero@@YAPEA_KXZ)"
im using VS2019 and i added the 64 and 32 bit minhook .lib files to the linker in my project. Im guessing this is because i gotta add the .dll files somewhere?
Hi, sorry for this noob question
I just started to work with c++ and kiero today, so I dont know anything
I want to know its possible to pass extra argument to hkPresent?
curently its look like this in d3d11_impl.cpp
long __stdcall hkPresent11(IDXGISwapChain* pSwapChain, UINT SyncInterval, UINT Flags)
{
//some code
}
its possible to pass some extra argument to it?
so lets say in main.cpp we have impl::d3d11::init(1);
, and in d3d11_impl.cpp void impl::d3d11::init(int arg)
how can i pass it to
assert(kiero::bind(8, (void**)&oPresent, hkPresent11) == kiero::Status::Success);
and get it in __stdcall hkPresent11
?
and one other time sorry for noob question
Hello. I am hooking Reset and Present like this but it does not seem to work when the game is in full screen.
#define KIERO_USE_MINHOOK 1
if (kiero::init(kiero::RenderType::D3D9) == kiero::Status::Success)
{
kiero::bind(16, (void**)&context::reset_original, context::reset_hook);
kiero::bind(17, (void**)&context::present_original, context::present_hook);
}
Present never gets called, but it works fine in borderless / windowed mode.
The game's name is Rocket League.
Thanks in advance.
Tried writing my own code for a DX11 hook with kiero, it crashed on line 322 of kiero.cpp in kiero::init(). Memory Access Violation.
So I downloaded https://github.com/rdbo/ImGui-DirectX-11-Kiero-Hook and compiled + injected it into my process. Crashed again, same line, same error.
Exception thrown at 0x2E741A8C in Among Us.exe: 0xC0000005: Access violation executing location 0x2E741A8C.
This is the line it crashes on, any ideas?

Program I'm trying to hook is Among Us
saw an old issue (#8) and figured it would be really helpful, especially when using this project as a submodule.
Hello!
Firstly, thank you for making this library!
I am using this library for quite some time now, and I noticed that a game that I'm trying to hook to is using D3D9Ex instead of D3D9.
Hooking this game through D3D9 works just fine, but the game calls D3D9Ex's PresentEx
instead of D3D9's Present
, which is causing weird issues with imgui and my code.
I have written a basic implementation of this over at my fork based on your d3d9 code, and I am actively using this code in my personal projects.
This code does work and function correctly (I am now able to hook PresentEx
), but the reason why I have not created a pull request is because I am having a conflicted standpoint: is it more correct to add it as an "extension" to D3D9, or as it's own separate RenderType?
I would love to discuss this for code review, and hopefully add it to this repository.
Thank you!
need fix
I'm creating an issue since I was not able to find any contact information for the author.
For the project I am currently working on I need to hook each and every one of the D3D11 methods.
My problem now is that there are some functions (e.g. SetPrivateData), provided by different interfaces (e.g. Device, DeviceChild,...).
How can i know which hook function needs which interface as an input parameter?
To clarify:
#define D3D11_METHODS \
X(3, HRESULT, SetPrivateDataDevice, ID3D11Device*, pDevice, REFGUID, guid, UINT, DataSize, const void*, pData) \
X(4, HRESULT, SetPrivateDataInterfaceDevice, ID3D11Device*, pDevice, REFGUID, guid) \
X(5, HRESULT, GetPrivateDataDevice, ID3D11Device*, pDevice, REFGUID, guid, UINT*, pDataSize, void*, pData)\
X(6, HRESULT, GetParent, IDXGIObject*, pObject, REFIID, riid, void**, pParent)
This is how i hook every single function. It's a macro that is expanded by the compiler, since every hook is identical.
I cannot define this macro for the functions with multiple entries in the METHODSTABLE.txt
without trial and error. Do I just need to try and see which one is correct?
Alright, so basically I'm trying to hook into DirectX into a unity game right,
and no work.
It doesn't crash, it says the method is working, and it does nothing.

Just FYI, these assertions will never fail - _index is an unsigned integer, meaning it will always be larger than or equal to zero.

Thanks a lot for this hook. I have the code, but when it comes to the loop
"if (kiero :: init (kiero :: RenderType :: D3D10) == kiero :: Status :: Success)", then the hook does not go into this loop and bypasses it (even if I use :: Auto). I am using a CSGO hook.

this is a project: https://mega.nz/folder/twR3iSib#41bValgZfDjturd0gW4__A
Thank you for your help!
Context:
I am using DX9 + imGUI + kiero + DLL injection.
Also, I have implemented the recommended hkReset hook for when the context resets/changes resolution/enters/exits full-screen.
This issue is broken into two parts:
If you inject the DLL & bind methods when the DirectX process is full-screen, the imGUI interface doesn't appear. However, if you inject the module when in windowed mode, then maximise or enter full-screen mode, the interface appears as expected.
When the DLL is injected and the DirectX process is in full-screen, you cannot ALT-TAB or use the Windows key to exit the process. ALT-TAB allows you to select a target window, but does not change focus to that new application.
Please let me know what additional data you may need, thanks.
I want to make http requests using libcurl and use the data I get back to display it using ImGUI. When I do this, it just hangs the entire application. Is there a best practice for this?
d3d9_impl.cpp
void impl::d3d9::init()
assert
Debug work only
Hi, nice hook. Just one thing, in kiero.cpp:
This will make d3d11 drawindexed hook fail:
const D3D_FEATURE_LEVEL featureLevels[] = { D3D_FEATURE_LEVEL_10_0, D3D_FEATURE_LEVEL_10_1, D3D_FEATURE_LEVEL_11_0 };
With this d3d11 hooks work fine:
D3D_FEATURE_LEVEL featureLevels[] = { D3D_FEATURE_LEVEL_11_0, D3D_FEATURE_LEVEL_10_1 };
Not sure why, did not look much into it.
i dont understand why is not working.
i compile it and follow ur readme demo
but when i inject nothing happen .. should i install something else?
i had
vstudio 2017 / dx sdk june 2010 .. complete c++ redist
For an universal graphic hooking library it would be nice if we can hook multiple instead of just one rendering type. Kiero checks for libraries and address already. We could get rid of specifying the rendering type, just check for all loaded libraries and addresses. And let us hook them if we want to.
Example:
int success = kiero::init();
if (kiero::isInitialized(kiero::RenderType::D3D9))
{
kiero::bind(kiero::RenderType::D3D9, 16, (void**)&oReset, hkReset);
}
if (kiero::isInitialized(kiero::RenderType::D3D10))
{
kiero::bind(kiero::RenderType::D3D10, 8, (void**)&oPresent, hkPresent);
}
Reason is that several games have loaded multiple rendering libraries even if they currently don't use them. For example RDR2 has loaded Vulcan and DX12. With the example above we can write one library that works no matter which rendering engine the user is currently using. While right now, we have to build one dx12 library and one vulcan library.
hi dude, is your pc fixed?
title pretty much says it all
#include "./hde/hde32.h" error
I try to hook Present function with detours, so first I want to get the original Present function with kiero, and it init failed because the D3D11CreateDeviceAndSwapChain return error in D3D11, anyone can resolve my question?
well its like
kiero::init(kiero::RenderType::D3D11);
👇
kiero::bind(8, (void**)&oEndScene, hkEndScene);
👇
kiero::shutdown();
👇
kiero::init(kiero::RenderType::D3D11);
👇
kiero::bind(8, (void**)&oEndScene, hkEndScene);
the last bind will not work for some reason, and i tried on d3d12, things still happen, what can i do
compiler: cmake 9.0.0 LLVM
So from the read me provided with this repo, I understand you have to write your hook depending on what you want to do.
What I don't understand is; after writing it, how do you compile the code? I don't know what to do from there.
Also, I get this error upon start-up:
CMake Error at C:\Users\User Name\Source\Repos\kiero\examples\imgui\imgui\examples\example_glfw_vulkan\CMakeLists.txt:23 (add_subdirectory):
add_subdirectory given source "../../../glfw" which is not an existing
directory. imgui_example_glfw_vulkan C:\Users\User Name\Source\Repos\kiero\examples\imgui\imgui\examples\example_glfw_vulkan\CMakeLists.txt 23
I did some study on CMake, and I understand that it is a utility for helping to build the project. In the CMakeLists.txt file, are you supposed to provide the address to the .cpp file containing your hooking functionality?
If anyone can lead me in the right direction, that would be great. Thank you.
I've cloned this repo and using VS 2019 I've successfully build the project. However only when I set KIERO_USE_MINHOOK
to 1
, I get 4 compiling error such as unresolved external symbol MH_DisableHook referenced in function "void __cdecl kiero::shutdown(void)"
In my VS project I've added minhook include folder to the include path directories:
<IncludePath>C:\kiero\minhook\include;$(IncludePath)</IncludePath>
Any idea what I'm doing wrong?
So, I've gotten Kiero to hook d3d11 like intended. But, when i try to unload, it just crashes.
void Remove(HWND hWindow)
{
SetWindowLongPtr(hWindow, GWLP_WNDPROC, (LONG_PTR)oWndProc);
}
void hook_dx11()
{
if (kiero::init(kiero::RenderType::D3D11) == kiero::Status::Success)
assert(kiero::bind(8, (void**)&phookD3D11Present, PresentHook) == kiero::Status::Success);
}
void remove_dx11()
{
kiero::unbind(8);
g_pd3dDevice->Release();
g_pd3dContext->Release();
ImGui_ImplWin32_Shutdown();
ImGui_ImplDX11_Shutdown();
ImGui::DestroyContext();
Remove(FindWindow(NULL, L"Call of Duty®: Black Ops II - Multiplayer"));
}
void Thread(HMODULE module)

while (true)
{
if (GetAsyncKeyState(VK_DELETE) & 0x8000)
break;
}
remove_dx11();
FreeConsole();
FreeLibraryAndExitThread(module, NULL);
}
As title.
in readme file :
if (kiero::init(kiero::RenderType::D3D9) == kiero::Status::Success) // 1
// or
if (kiero::init(kiero::RenderType::Auto) == kiero::Status::Success) // 2
{
// define KIERO_USE_MINHOOK must be 1
// the index of the required function can be found in the METHODSTABLE.txt
kiero::bind(42, (void**)&oEndScene, hkEndScene);
// If you just need to get the function address you can use the kiero::getMethodsTable function
oEndScene = (EndScene)kiero::getMethodsTable()[42];
}
the execution flow will go through the 1
condition, then it will skip the 2
body, am I right?
So, the hook can not be done.
It should be:
if (kiero::init(kiero::RenderType::D3D9) == kiero::Status::Success || // 1
kiero::init(kiero::RenderType::Auto) == kiero::Status::Success) // 2
{
// define KIERO_USE_MINHOOK must be 1
// the index of the required function can be found in the METHODSTABLE.txt
kiero::bind(42, (void**)&oEndScene, hkEndScene);
// If you just need to get the function address you can use the kiero::getMethodsTable function
oEndScene = (EndScene)kiero::getMethodsTable()[42];
}
So that whatever we choose, d3d9 or auto, it will always complete the hook.
Am I right?
BTW, thnx for your project, I love the code.
How do you allow the input to the imgui for directx11?
Xenos Injector Native Inject:
direct3D9->CreateDevice runs forever and does not create a device.
D3D11 error while creating the device.
Xenos Injector Manul Map:
Error: 0xC0000138
The OpenGL hook works fine in both cases, so it is unlikely that the bug is somewhere else
Issue #15 had the same error but I don't know what he means by "forgot to add the include and bin folders to the project using the buttons in vs2019" I added kiero.h, kiero.cpp, the whole impl folder, and minhook.h, in include directories. I dont know what im missing or need to do.
I added a few debug logging to get the actual HRESULT
when attempting to call CreateDXGIFactory
during initialization. The modules are found perfectly fine, and apparently the function is CreateDXGIFactory
is also found correctly.
However, when attempting to call in this block:
IDXGIFactory* factory;
HRESULT result = ((long(__stdcall*)(const IID&, void**))(CreateDXGIFactory))(__uuidof(IDXGIFactory), (void**)&factory);
if (result < 0)
{
::DestroyWindow(window);
::UnregisterClass(windowClass.lpszClassName, windowClass.hInstance);
return Status::IDXGIFactoryFailed;
}
I found it was returning the following error:
DXGI_ERROR_INVALID_CALL 0x887A0001
The application provided invalid parameter data; this must be debugged and fixed before the application is released.
I have done a bit of searching, but for some reason I can't determine the root cause. Any help or tips would be appreciated?
I'm trying to understand how to use your stuff properly as it seems to be very powerful, but I don't understand your example...
What's needed in your base cpp file to make it work ? How does bind work and what do you need to do to make it work ? Etc...
I think you should add more comments in the example.
Thanks !

I've hooked ImGui window in GTA SA (DirectX9). Everything works fine but whenever I try to alt-tab out of the game the screen goes black. Then if I return to the game everything works fine.
This is my present hook, https://pastebin.com/YhSnx0NL
I read something similar about it here.
I tried using the same reset as well but the same thing,
https://pastebin.com/ehCWZGYh
I've tried to test which might be causing this issue and seems like something in keiro::init()?
I'm not sure why you have typedef uint64_t uint150_t;
, but the resulting type is still only a 64-bit integer, not 150-bit.
You can't define integer sizes like this
I tried to use your examples, but if compiled in Release mode hkEndScene never gets called, because you youse assert in the init functions. A "How to setup"-Part in the Readme would be a very good idea i think.
dwm.exe hook error

had to change this line

to

idk maybe its just me lol
If I start a process by CREATE_SUSPENDED mode and inject a dll. Then when should I call init() function?
Everything is in the title.
I want to do something like a Foreach() in c# (maybe there is a better alternative).
Thanks !!
How do I make this work with OpenGL 3 ?
