Console Redirection

[SoulOfSet]

Im trying to redirect console output from the arma dedicated into a windows form application written in C#. I'm having a hell of a time with it and cant seem to quite get it right.

This is what I have so far. It just hangs the program though when it's called though.

Code: Select all

public static void startArma()
        {
            armaServer.StartInfo.UseShellExecute = false;
            armaServer.StartInfo.ErrorDialog = false;

            armaServer.StartInfo.RedirectStandardOutput = true;
            armaServer.StartInfo.CreateNoWindow = true;

            armaServer.StartInfo.FileName = @"C:\Program Files\Armagetron Advanced Dedicated\armagetronad_dedicated.exe";
            armaServer.Start();

            StreamReader armaOutputReader = ControlFunctions.armaServer.StandardOutput;

            string armaOutput = armaOutputReader.ReadToEnd();
        }

May I ask why you want to do that?

Oh dear. Should of explained that. I'm making a dedicated server UI. Kinda my intro to C# project. I've got most of it done besides this little roadblock

Not sure off the top of my head, but doesn't ReadToEnd imply that it will load all output up until the process terminates? I think you want something that reads only until a new line character. This'll need to be in some sort of loop, e.g.:

Code: Select all

While (Tron is Running) {
    Read a line from the console
    Process based on that line
}

Is there a BufferedStreamReader? That would be the right direction to look in I think.

That would explain why it hangs when the program starts and continues when I manually end the process. Thanks for that. I'll look into what you've said and communicate my findings :3.

Or use EventHandlers

Code: Select all

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Diagnostics;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Process Proc = new Process();
            Proc.StartInfo.FileName = "C:\\Users\\Niklas\\Desktop\\tron\\0.4-queue+timeleft+scoreboard\\build\\dist\\armagetronad_dedicated.exe";
            Proc.StartInfo.UseShellExecute = false;
            Proc.StartInfo.RedirectStandardOutput = true;
            Proc.StartInfo.RedirectStandardError = true;

            Proc.OutputDataReceived += new DataReceivedEventHandler(receivedData);
            Proc.ErrorDataReceived += new DataReceivedEventHandler(receivedError);

            Console.WriteLine("starting the process...");
            Proc.Start();

            Proc.BeginOutputReadLine();
            Proc.BeginErrorReadLine();

            Proc.WaitForExit();
        }

        static void receivedData(object o, DataReceivedEventArgs data)
        {
            if (data.Data != null)
            {
                Console.WriteLine(data.Data);
                Console.Out.Flush();
            }
        }

        static void receivedError(object o, DataReceivedEventArgs error)
        {
            if (error.Data != null)
            {
                Console.Error.WriteLine(error.Data);
                Console.Error.Flush();
            }
        }
    }
}

Yeah I ended up with something similar to that. Im just trying now to get it to work with the windows forms. Weird protection thing.
