推荐答案

我的主意不好.进程是孤立的，您正在尝试打破它.通过Windows手柄进行的通信是Windows系统独有的过时功能，该功能不能移植到任何其他系统中，这源于Windows操作系统之前的版本以及尚未使用英特尔保护模式CPU架构的Windows版本.使用它通常是不好的.进程间通信的正确方法是进程间通信IPC :

Bad idea, I would say. The processes are isolated, and you are trying to break it. Communication via the Windows handles is obsolete feature unique for Windows systems, not portable to any others, stemmed from the versions of Windows before it was an OS and when Intel protected mode CPU architecture was not yet used. Using it is generally bad. The proper way of inter-process communication is, well Inter-Process Communication, IPC:
http://en.wikipedia.org/wiki/Inter-process_communication[^].

If a process is some application with not accessible source code or an API (so you cannot make it an in-proc plug-in or something working in your process) and it is not designed to use any kind of IPC — then no luck. Before thinking of dirty tricks of using Windows handle manipulation, I would think really hard if the integration of it can really be justified, usually not.
