Question

我知道这段代码很草率，但是我想知道为什么当我使用ReadProcessMemory（）函数时，看不到存储在相关地址中的字符串。

    //If the game window is open then this function grabs the process ID.
if(FinderCheck)
{
    DWORD procID;

    GetWindowThreadProcessId(hwnd, &procID);

    //All so access you can read and write to process memory.
    HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS,FALSE,procID);

    if(procID = NULL)
    {
        cout << "Error: Failed to Obtain Process ID" << endl;
    }
    else
    {
        while(true)
        {


        //To read the process memory this line writes the memory data to buffer
        //Remember to change the address every time you boot the process or it will not work.
        ReadProcessMemory(handle, (PBYTE*)0xDC8F1AA904,&Cursor,sizeof(Cursor),0);
        cout << Cursor << endl;
        cout << "Test" << endl;

        Sleep(500);
        }
    }

可悲的是，此if语句将始终计算为false，您缺少第二个“ =”。这也意味着从这一点来看if(procID = NULL)是procID。

其余的代码呢？您能否向我们展示NULL的定义，以及如何实现Cursor？

为什么我看不到绳子？
