请不要害怕，但是下面的代码，如果你熟悉 ctypes 或 C 应该很容易阅读。
我一直试图让我的 ReadProcessMemory() 和 WriteProcessMemory() 函数工作这么久，并且尝试了几乎所有的可能性，但正确的一个。
它启动目标程序，返回它的 PID 并处理得很好。但我总是收到错误代码 5 - ERROR_ACCESS_DENIED。当我运行读取功能时（暂时忘记写入）。我正在启动这个程序，因为我认为它是一个带有 PROCESS_ALL_ACCESS 或 CREATE_PRESERVE_CODE_AUTHZ_LEVEL 的 CHILD 进程。
当我打开句柄时，我也尝试过 PROCESS_ALL_ACCESS 和 PROCESS_VM_READ。
我也可以说它是一个有效的内存位置，因为我可以使用 CheatEngine 在正在运行的程序中找到它。
至于 VirtualQuery() 我得到一个错误代码 998 - ERROR_NOACCESS 这进一步证实了我怀疑它是一些安全/特权问题。
任何帮助或想法将不胜感激，再次，这是我到目前为止的整个程序，不要让它吓到你 =P。
