Python Ctypes Read/WriteProcessMemory() -错误5/998帮助！
Python Ctypes Read/WriteProcessMemory() -错误5/998帮助！
提问于 2010-03-23 18:56:34
请不要害怕，但下面的代码，如果你熟悉ctype或C语言，它应该很容易阅读。
很长时间以来，我一直在尝试让我的ReadProcessMemory()和WriteProcessMemory()函数正常工作，并且尝试了几乎所有的可能性，除了正确的一个。
它启动目标程序，返回它的PID和句柄。但是我总是得到一个5- ERROR_ACCESS_DENIED的错误代码。当我运行读取函数时(暂时不考虑写入)。我将这个程序作为我认为是PROCESS_ALL_ACCESS或CREATE_PRESERVE_CODE_AUTHZ_LEVEL的一个子进程来启动。
当我打开手柄时，我也尝试过PROCESS_ALL_ACCESS和PROCESS_VM_READ。
我还可以说它是一个有效的内存位置，因为我可以在运行CheatEngine的程序中找到它。
至于VirtualQuery()，我得到了一个错误代码998 - ERROR_NOACCESS，这进一步证实了我对它是安全/特权问题的怀疑。
任何帮助或想法都将非常感谢，再次强调，到目前为止这是我的整个程序，不要让它吓到你=P。
