如何在C ++中运行应用程序并写入其stdin并在Windows中从其stdout读取

Question

I want to run an application in c++ and read its stdout and write t stdin in windows? No popup should be generated.

Can I do it easily using windows services?

I found that I maybe able to do this with POCO, but do I really need this?

Is there solution in std library for this?

You can spawn a child process and then gain access to its stdin and stdout pipes. You have to use WinAPI to achieve this. See example here: http://msdn.microsoft.com/en-us/library/ms682499(v=vs.85).aspx

You may use Qt and it's QProcess class to read/write child process output/input.
