使用GetModuleInformation函数 [英] Use GetModuleInformation Function

问题描述

我尝试使用GetModuleInformation，但是每次使用它时，应用程序都会崩溃.

我的代码:

I have tryed to use the GetModuleInformation, but every time I used it, the application crash.

My code:

#include <windows.h>
#include <tlhelp32.h>
#include <psapi.h>

using namespace std;

HMODULE GetRemoteModuleHandle(DWORD lpProcessId, LPCSTR lpModule);

int main() {
  HWND hWnd = FindWindow(0, "Counter-Strike Source");
    if(hWnd == 0){
      MessageBox(0, "Error cannot find window.", "Error", MB_OK|MB_ICONERROR);
    } 
    else {
      DWORD proccess_ID;
      GetWindowThreadProcessId(hWnd, &proccess_ID);


      HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, proccess_ID);
      HMODULE hModule = GetRemoteModuleHandle(proccess_ID, "engine.dll");

      MODULEINFO mi;
      GetModuleInformation(hProcess, hModule, &mi, sizeof(mi));
   }   
   return 0;
}

HMODULE GetRemoteModuleHandle(DWORD lpProcessId, LPCSTR lpModule)
{
    HMODULE hResult = NULL;
    HANDLE hSnapshot;
    MODULEENTRY32 me32;

    hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, lpProcessId);
    if (hSnapshot != INVALID_HANDLE_VALUE)
    {
        me32.dwSize = sizeof(MODULEENTRY32);
        if (Module32First(hSnapshot, &me32))
        {
            do
            {
                if (!stricmp(me32.szModule, lpModule))
                {
                    hResult = me32.hModule;
                    break;
                }
            }
            while (Module32Next(hSnapshot, &me32));
        }
        CloseHandle(hSnapshot);
    }
    return hResult;
}

模块的句柄不是NULL，所以我认为它已创建！ :O
我希望您能为我提供帮助:)

The Handle to the Module isn''t NULL so I think it is created! :O
I hope you can help me :)

推荐答案

我建​​议您在调试器下运行它，并在调用该函数的行上放置一个断点.

I suggest that you run it under the debugger, and put a break-point on the line where you call that function.
