DLL注入工程，除非我在Qt Creator中編譯它

Question

我的問題很簡單，標題解釋了這一切。基本上，當我用Visual Studio 2013編譯我的程序時，dll注入完全正常。當我在Qt Creator中編譯完全相同的程序時，它不會。

我似乎有同樣的問題，因爲這傢伙：Why does Qt not work with dll injection?

這裏是我的代碼：

Injector.h

#ifndef INJECTOR_H_INCLUDED 
#define INJECTOR_H_INCLUDED 

#include <Windows.h> 
#include <string> 

class Injector 
{ 
public: 
    /** 
    * Loads a DLL into the remote process 
    * @Return true on sucess, false on failure 
    */ 
    bool InjectDll(DWORD processId, std::string dllPath); 
private: 
}; 

#endif // INJECTOR_H_INCLUDED 

Injector.cpp

#include "Injector.h" 

bool Injector::InjectDll(DWORD processId, std::string dllPath) 
{ 
    HANDLE hThread, hProcess; 
    void* pLibRemote = 0; // the address (in the remote process) where szLibPath will be copied to; 

    HMODULE hKernel32 = GetModuleHandleA("Kernel32"); 

    char DllFullPathName[_MAX_PATH]; 
    GetFullPathNameA(dllPath.c_str(), _MAX_PATH, DllFullPathName, NULL); 
    printf("Loading dll: %s\n", DllFullPathName); 

    // Get process handle 
    hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, processId); 

    // copy file path in szLibPath 
    char szLibPath[_MAX_PATH]; 
    strcpy_s(szLibPath, DllFullPathName); 

    // 1. Allocate memory in the remote process for szLibPath 
    pLibRemote = VirtualAllocEx(hProcess, NULL, sizeof(szLibPath), MEM_COMMIT, PAGE_READWRITE); 

    if (pLibRemote == NULL) 
    { 
     printf("Couldn't allocate memory, please restart with administrator privileges\n"); 
     return false; 
    } 

    // 2. Write szLibPath to the allocated memory 
    WriteProcessMemory(hProcess, pLibRemote, (void*)szLibPath, sizeof(szLibPath), NULL); 

    // 3. Force remote process to load dll 
    hThread = CreateRemoteThread(hProcess, NULL, 0, (LPTHREAD_START_ROUTINE)GetProcAddress(hKernel32, "LoadLibraryA"), pLibRemote, 0, NULL); 

    if (hThread == NULL) 
    { 
     printf("Couldn't load DLL"); 
     return false; 
    } 

    printf("Dll successfully loaded\n"); 

    return true; 
} 

的main.cpp

#include "injector.h" 
int main(int argc, char *argv[]) 
{ 
    Injector inject; 
    DWORD processId = 6224; 
    inject.InjectDll(processId, "MyDLL.dll"); 
    system("pause"); 
} 

這是DLL（我用在這兩個方案中的同一個DLL，我沒有重新編譯）：

#include <Windows.h> 
#include <stdio.h> 

BOOL APIENTRY DllMain(HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved) 
{ 
    switch (ul_reason_for_call) 
    { 
    case DLL_PROCESS_ATTACH: 
     AllocConsole(); 
     freopen("CONOUT$", "w", stdout); 

     printf("base address: %X\n", (DWORD)GetModuleHandle(NULL)); 

     break; 
    case DLL_PROCESS_DETACH: 
     FreeConsole(); 
    } 

    return TRUE; 
} 

在VS2013編譯正確的程序注入DLL，而編譯在Qt Creator中的程序說，DLL注入成功，但DLL永遠不會被注入。

注：我試圖注入的程序在這兩種情況下都是相同的，並且不是用Qt製作的。

以下是編譯器輸出：

的Visual Studio：

CL/C /紫/ W3/WX-/ SDL/O2 /愛/ Oy-/GL/d _CRT_SECURE_NO_WARNINGS/D/ _MBCS/Gm-/EHsc/MD/GS/Gy/fp： errorReport：prompt Injector.cpp main.cpp

任何幫助將不勝感激，謝謝。

Answer 1

的問題是，Qt的編譯了一個程序在64位，而Visual Studio中的32位編譯它。

我仍然不知道爲什麼，在32位的目標註入DLL 32位失敗，因爲64位注射器的，但現在我解決我的問題......
