我正在通过在 Microsoft 的 Spider Solitaire 上使用它来测试整个基本/静态指针。所以我得到了玩家使用的“移动”数量的基本指针，作弊引擎告诉我它是“SpiderSolitaire.exe+B5F78”。所以现在我被困在如何弄清楚 SpiderSolitaire.exe 的起始地址是什么（当然每次程序启动时都会改变）。如何找到 SpiderSolitaire.exe 的起始地址，以便我可以添加偏移量并获取“移动”值的真实地址（当然是在 c++ 中）？

这是另一种方式，用 Visual Studio 2015 编写，但应该向后兼容。

#define PSAPI_VERSION 1
#include <windows.h>
#include <tchar.h>
#include <stdio.h>
#include <psapi.h>

// To ensure correct resolution of symbols, add Psapi.lib to TARGETLIBS
#pragma comment(lib, "psapi.lib")

void GetBaseAddressByName(DWORD processId, TCHAR *processName)
{
    TCHAR szProcessName[MAX_PATH] = TEXT("<unknown>");

    HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION |
        PROCESS_VM_READ,
        FALSE, processId);

    if (NULL != hProcess)
    {
        HMODULE hMod;
        DWORD cbNeeded;

        if (EnumProcessModulesEx(hProcess, &hMod, sizeof(hMod),
            &cbNeeded, LIST_MODULES_32BIT | LIST_MODULES_64BIT))
        {
            GetModuleBaseName(hProcess, hMod, szProcessName,
                sizeof(szProcessName) / sizeof(TCHAR));
            if (!_tcsicmp(processName, szProcessName)) {
                _tprintf(TEXT("0x%p\n"), hMod);
            }
        }
    }

    CloseHandle(hProcess);
}

int main(void)
{
    DWORD aProcesses[1024];
    DWORD cbNeeded;
    DWORD cProcesses;

    // Get the list of process identifiers.
    if (!EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded))
        return 1;

    // Calculate how many process identifiers were returned.
    cProcesses = cbNeeded / sizeof(DWORD);

    // Check the names of all the processess (Case insensitive)
    for (int i = 0; i < cProcesses; i++) {
        GetBaseAddressByName(aProcesses[i], TEXT("SpiderSolitaire.exe"));
    }

    return 0;
}

这是一些用于查找给定进程的基地址的代码。

请注意，此代码使用多字节字符集；在 VS2012 中，这是从 Properties > Configuration Properties > Project Defaults > Character Set > Use Multi-Byte Character Set 设置的。

您应该查看可执行文件中的结构 IMAGE_OPTIONAL_HEADER。我还建议您阅读这份出色的指南：http: //msdn.microsoft.com/en-us/library/ms809762.aspx
