My application is a multi threaded app (using wxThreads). At the moment, the main thread along with it's child worker threads are outputting various messages to Stdout (using cout). I have a new frame/window with a wxTextCtrl, and would like to redirect all the StdOut messages in to it. GuiLogFrame *logframe; logframe = new...
I'm trying to run wrap a simple (windows) command line tool up in a PyQt GUI app that I am writing. The problem I have is that the command line tool throws it's progress out to stdout (it's a server reset command so you get "Attempting to stop" and "Restarting" type output. What I am trying to do is capture the output so I can display ...
I want to run blender from the command line through a ruby script, which will then process the output given by blender line by line to update a progress bar in a GUI. It's not really important that blender is the external process whose stdout I need to read. I can't seem to be able to catch the progress messages blender normally prints ...
I'm working on getting some legacy code under unit tests and sometimes the only way to sense an existing program behavior is from the console output. I see lots of examples online for how to redirect stdout to another file in C++, but is there a way I can redirect it to an in-memory stream so my tests don't have to rely on the disk? I'...

I am using fork() and execvp() to spawn a process that must believe it is connected to an interactive terminal for it to function properly. Once spawned, I want to capture all the output from the process, as well as be able to send input to the process. I suspect psuedo-ttys may help here. Does anyone have a snippet on how to do this?...

I'm using python's ftplib to write a small FTP client, but some of the functions in the package don't return string output, but print to stdout. I want to redirect stdout to an object which I'll be able to read the output from. I know stdout can be redirected into any regular file with: stdout = open("file", "a") But I prefer a metho...
When I run tests with ./manage.py test, whatever I send to the standard output through print doesn't show. When tests fail, I see an "stdout" block per failed test, so I guess Django traps it (but doesn't show it when tests pass). ...

I've written a small console application to wrap a third-party DLL that has issues. I am calling it from a GUI application using _popen, and just want to read a value from the console program's standard output. In doing so, an undesirable console window is briefly displayed. I am aware that this can be avoided by using a certain STARTUP...

I am currently calling a DLL from labview, but I need to be able to debug it realtime (because of it's accessing time sensitive hardware). I would like to just printf() my error assert messages but I am unsure about how to open a DOS window from within the DLL to dump error information to. Has anyone done this before? I know I could do t...
I have a Perl script which forks and daemonizes itself. It's run by cron, so in order to not leave a zombie around, I shut down STDIN,STDOUT, and STDERR: open STDIN, '/dev/null' or die "Can't read /dev/null: $!"; open STDOUT, '>>/dev/null' or die "Can't write to /dev/null: $!"; open STDERR, '>>/dev/null' or die "Can't write to /dev/nu...
