Hi
In what way not working ?
std::cout is normally displayed in Application Output pane. -
it works when i changed to project properties :
project properties -> linker -> system -> subsystem : console(/subsysteme:console)
[before it was : -> subsystem : windows(/subsysteme:windows) ]

Well std::cout is not visible in GUI projects.
Only when its a console app.
So that is pretty normal. -
yup :))

See e.g. https://stackoverflow.com/questions/16703835/visual-studio-how-can-i-see-cout-output-in-a-non-console-application if you'd still like a way to see your output when a GUI program.... -

Hi,
What are you trying to use it for ?
If you want the GUI program to also have a "command prompt" showing
you will need to create on using native windows calls.
If you just want to use std::cout for some debugging, the easy way is to redirect them to
a file and load in PlainTextEdit in the app. -
