Question

How to get the output of a Executable made in C++ in Rich text Box in C#?

The question is self explanatory, but just to add on further.

Say for i run a compiled program whose output is:

Made by C++

Now i want the output of this program (which is console based) in my Rich text Box in C#.

If the program name is:

example.exe

How do i do it?

Answer 1

Usually when you spawn a process you’re able to get it’s stdout and stderr descriptors.
So use appropriate class to spawn example.exe process and read it’s stdout and err.

Use following classes:

ProcessStartInfo
Process 

//then Process method would do the trick
proc.StandardOutput.ReadToEnd();

EDIT
I’ve found following example on net:

process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.OutputDataReceived += (sender, args) => Console.WriteLine("received output: {0}", args.Data);
process.Start();
process.BeginOutputReadLine();
