Hello.

I decided to use MinHook for it's simplicity.

I have compiled it for 64 bit platform but when I inject \Win32Project1\x64\Release\Win32Project1.dll into notepad.exe which is 64 bit application, CE says Failed injecting the DLL. Now I know for sure that both dll and target are 64 bit. And the same project when I compiled it for x86 succeeded with random x86 target.

Has anyone used this library? Any ideas what might cause it? Wrong project settings?

Here's my link to my project:
http://autoit.net.ee/downloads/Win32Project1.zip
I posted here whole project because I didnt know wether I should post just cpp file or project itself.

I tried downloading your project 3 times and it's not working. Got to ask the obvious, but are you hooking the right address/function? I'm sure you are, but always gotta ask. I've never used this, but from what he stated in his article several projects have used it
Quote:
As of January 2015, this library is used in some projects: 7+ Taskbar Tweaker, Better Explorer, DxWnd, NonVisual Desktop Access, Open Broadcaster Software, QTTabBar, x360ce and more. I am happy finding that this project is helpful to people.

I took a look at a few of those projects and I think you might want to check out Open Broadcaster Software's project. They use the hook for 32/64 and cross-platform. Their project is open source on github and can be found here.

Is link not working or project itself? I just tested and it worked for me. Link in first post is direct download. It should not even lead you away from this page.

Does this link work better? I dont know what browser you have but I tested this link with firefox.
http://www.megafileupload.com/d9MY/Win32Project1.zip?pt=wnEk0iEDBGr3VwrhSFqaop3E%2BgQ1EvzAUDmrv7Mrtl8%3D

This is my code:
Code:
#include <Windows.h>
#include "MinHook.h"

#if defined _M_X64
#pragma comment(lib, "libMinHook.x64.lib")
#elif defined _M_IX86
#pragma comment(lib, "libMinHook.x86.lib")
#endif

// Helper function for MH_CreateHookApi().
template <typename T>
inline MH_STATUS MH_CreateHookApiEx(LPCWSTR pszModule, LPCSTR pszProcName, LPVOID pDetour, T** ppOriginal)
{
    return MH_CreateHookApi(pszModule, pszProcName, pDetour, reinterpret_cast<LPVOID*>(ppOriginal));
}

typedef HANDLE (WINAPI *CREATEFILEW)(LPCWSTR, DWORD, DWORD, LPSECURITY_ATTRIBUTES, DWORD, DWORD, HANDLE);

// Pointer for calling original MessageBoxW.
CREATEFILEW fpCreteFileW= NULL;

// Detour function which overrides MessageBoxW.
HANDLE WINAPI DetourCreateFileW(LPCWSTR lpFileName, DWORD dwDesiredAccess,DWORD dwShareMode, LPSECURITY_ATTRIBUTES lpSecurityAttributes, DWORD dwCreationDisposition, DWORD dwFlagsAndAttributes, HANDLE hTemplateFile)
{
    return fpCreteFileW(lpFileName, dwDesiredAccess, dwShareMode, lpSecurityAttributes, dwCreationDisposition, dwFlagsAndAttributes, hTemplateFile);

}


INT APIENTRY DllMain(HMODULE hDLL, DWORD Reason, LPVOID Reserved)
{
    switch(Reason)
    {
    case DLL_PROCESS_ATTACH:
      // Initialize MinHook.
      if (MH_Initialize() != MH_OK)
      {
         MessageBox(0,L"fail1",L"fail",0);
         return 1;
      }

      // Create a hook for MessageBoxW, in disabled state.
      if (MH_CreateHookApiEx(L"Kernel32", "CreateFileW", &DetourCreateFileW, &fpCreteFileW) != MH_OK)
      {
         MessageBox(0,L"fail2",L"fail",0);
         return 1;
      }

      // Enable the hook for MessageBoxW.
      if (MH_EnableHook(&CreateFileW) != MH_OK)
      {
         MessageBox(0,L"fail1",L"fail",0);
         return 1;
      }
        break;
    case DLL_PROCESS_DETACH:
      // Disable the hook for MessageBoxW.
      if (MH_DisableHook(&CreateFileW) != MH_OK)
      {
         return 1;
      }

      // Uninitialize MinHook.
      if (MH_Uninitialize() != MH_OK)
      {
         return 1;
      }
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
        break;
    }
    return TRUE;
}

The dll injects fine here ? Sure you are running 64bit version of notepad ?

Something must be wrong on your end.

is it the "modern" app version of calculator?
If so, is the dll in a location with security rights for everyone? (might have to add that specifically)

Edit: I figured that if I use CE then it fails but when I use Extreme Injector v3.exe then it works Razz

Edit2: after updating CE from 6.2 to 6.4 it worked with CE also. Sorry for wasting your time guys Sad . Didnt even expect to have it fixed with using something else than CE cuz I thought it to be so universal that "it definitely cant be injector's fault."

Edit3: now I have CE6.2 and 6.4 both. 6.2 keeps failing, 6.4 works every time.

I didn't compile your code but used the dll already in the release folder. Used CE to inject it.

I'll play with this some more and see if i get the same error
