# Ways to Print and Capture Text Output of a Process

In my previous blog post “Launching process programmatically: system vs CreateProcess vs ShellExecute”, I investigated various ways of launching a new process when programming in C++ using Windows, with the focus on different ways to specify a path to the executable file. Today, I want to describe a related topic: we will investigate ways that a process can print some text messages (standard output, standard error, WriteConsole function, DebugOutputString function), how we can observe this output and, finally, how we can capture it programmatically when launching a subprocess using CreateProcess function.
