【问题描述】：
我正在为我的网络制作安全程序。其中一个实例是检查和监控调用了哪些 api 和库。执行此操作的 dll 以及与之配套的程序已经完成。但是有一个问题我似乎无法解决。
当尝试使用NtCreateThreadEx 将我的 dll 注入系统进程（例如 explorer.exe，我的主要测试系统进程）时，我得到返回值：C0000022，它的含义类似于：Status_Access_Denied（它返回NTSTATUS，但 DWORD 可以）
我不知道该怎么做，我以管理员身份运行，我提高了权限，并使用了正确的功能，但我仍然得到 c0000022
这是我用来注入的代码

【问题讨论】：
-
我想编辑您的问题以将您的代码直接添加到问题中，但它太长了！你真的希望有人审查你的整个代码吗？！
-
不，我不是，事实上，在我尝试将代码注入系统进程之前，代码工作正常，没有错误也没有问题。在其他应用程序中它工作正常。
-
问题是这个问题在过去的bin早已消失之后仍然会在这里（并且可以通过谷歌搜索）。
-
@Unknown：pastbin 上的代码示例不会永远存在。当代码示例将在几天/几个月/几年内消失时，这个问题将保留，但将包含一个死链接。
-
我现在可以将它们添加到我的帖子中，问题是我第一次发布此问题时无法使用工具栏。
