Hi,

I would like to make a new app able to group several private programs outputs. No need to know about coding methods, as its likely a conceptual issue. The idea is this:

-Program A (SCADA system) provides me an output.
-Program B (different SCADA system) provides me another output.

-Program C groups both of them in one interface, alowing to interact with programs A and B through C.

If anybody knows the conceptual bases that I might have, please let me know, this would be really helpfull.

What I have tried:

Gogoled, not really tied to code this as I must lead a coding team.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with - we get no other context for your project.
Imagine this: you go for a drive in the country, but you have a problem with the car. You call the garage, say "it broke" and turn off your phone. How long will you be waiting before the garage arrives with the right bits and tools to fix the car given they don't know what make or model it is, who you are, what happened when it all went wrong, or even where you are?

That's what you've done here. So stop typing as little as possible and try explaining things to people who have no way to access your project!

You are going to have to provide a fair amount of actual information in order to get a meaningful response.

Use the "Improve question" widget to edit your question and provide better information.

Thanks.

It is not clear exactly how you want to interact. A and B could send their output to files which C could read. C could start A and B and capture their output via pipe system calls. The three could communicate via sockets ...

So you need to clarify exactly how you wish to interact between them.

Idealy, starting C would start A and B. Then A and B would send their output to C. C would be as a virtual user in this pipe: standart output from A and B would become an input to C.

Can this be done on python? What language would you recommend for the process?

Thanks for you attention Richard,

Kind regards.

It can probably be done in some way in any language but there are things we don't know - and you presumably do - that are relevant: read what Richard said and think about your apps and how they work at present. We have no way of knowing stuff you don't tell us!

I don't recommend any language. That has to be your choice based on your skills and experience. See also this example from MSDN based on C/C++: Creating a Child Process with Redirected Input and Output - Win32 apps | Microsoft Docs[^].

Thanks a lot Richard. This will be helpfull for me.

Thank you too OriginalGriff, I know sometimes learners are annoying!

"I know sometimes learners are annoying!"
While that is sometimes true, the main problem we face in answering questions is lack of detail. We have no knowledge of the people who ask questions, their background, their skills, exactly what the problem is, etc. All we have is what is posted in the question and we are often forced to make guesses as to how and what to answer. That is not annoying, but it can be extremely frustrating.

"I must lead a coding team" - Great! All you need to do is to meet with your team and do a brainstorm! In other words, do what leader have to do. People of your team do not expext from you to be the smartest. They want to have a person who can lead them. Got it?
