MFC编程修改内存数据程序

    //在这页中查找
    DWORD* pageDword;
    for(int i=0; i<(int)4*1024; i++)
    {
        pageDword = (DWORD*)&pageByte[i];
        if (pageDword[0] == valueChange)
        {
            if (addrCount >= 1024)
            {
                return FALSE;
            }
                //添加到全局变量中
            addrList[addrCount] = baseAddr + i;
            addrCount++;
        }
    }
}
BOOL CMemoRepairDlg::FirstFind(DWORD valueChange)
{
    const DWORD dwOneGB = 1024*1024*1024;
    const DWORD dwOnePage = 4096;
    if (hProcess == NULL)
    {
        return FALSE;
    }
    //操作系统类型
    DWORD systemBase;
    OSVERSIONINFO vinfo ={sizeof(vinfo)};
    ::GetVersionEx(&vinfo);
    if (vinfo.dwPlatformId == VER_PLATFORM_WIN32_WINDOWS)
    {
        systemBase = 4*1024*1024;
    }
    else
    {
        systemBase = 640*1024;
    }

 //在开始地址到2GB的地址空间查找
    for (; systemBase < 2*dwOneGB; systemBase += dwOnePage)
    {
        ComparePage(systemBase, valueChange);
    }
    return TRUE;
}

BOOL CMemoRepairDlg::NextFind(DWORD valueChange)
{
    //保存地址个数，初始化addrCount的值
    int mOrgCnt = addrCount;
    addrCount = 0;
    BOOL bRet = FALSE;
    DWORD dwReadValue;
    for (int i=0; i     {
        if (::ReadProcessMemory(hProcess,(LPVOID)addrList[i],&dwReadValue,sizeof(DWORD),NULL))
        {
            if (dwReadValue == valueChange)
            {
                addrList[addrCount] = addrList[i];
                addrCount++;
                bRet = TRUE;
            }
        }
    }
    return bRet;
}
void CMemoRepairDlg::ShowList()
{
    editStr ="";
    CString str="";
    UpdateData(FALSE);
    editStr.Format("%d个相同的地址.",addrCount);
    for(int i=0; i     {
        str.Format("%s %d '\n';",editStr, addrList[i]);
        editStr = str;
    }
    UpdateData(FALSE);

}

BOOL CMemoRepairDlg::WriteMemory(DWORD valueAddr, DWORD valueChange)
{
    return ::WriteProcessMemory(hProcess, (LPVOID)valueAddr, &valueChange, sizeof(DWORD), NULL);
}

再就是新建一个程序，作为启动的进程程序：Testor

这个程序的Testor.exe文件将影响到上面启动进程的路径。 Testor.cpp:

#include

using namespace std; int ChangeNum = 0; //全局变量

int main()
{
    int insideNum = 200;        //局部变量
    ChangeNum = 1600;

    while (true)
    {
        printf(" insideNum = %d, addr = %X; ChangeNum = %d, addr = %X \n",
            ++insideNum, &insideNum, ++ChangeNum, &ChangeNum);
        getchar();
    }
    return 0;
}
};
