stdout live

Hi.

I need help with two things:

1) I'm getting the input from a JAR program, the minecraft server software to be exact.
The code I'm using is working great, for 2 lines of text.
After that I'm getting nothing.
These two lines are information about the game (how many achievements and recipes).
So when I run the program I get this info:

Quote:

---

148 recipes
16 achievements

---

which is correct, but only a part of all the text.

2) I only get the text when I close the server program, its not "live".
So I first run my program, which runs the server software, I close the server software and I get the stdout.
I wan't stdout live!

Here is my code:

Code:

---

private void button2_Click(object sender, EventArgs e)
        {
            string line;
            ProcessStartInfo processStartInfo = new ProcessStartInfo("java.exe", "-Xms512M -Xmx1024M -jar minecraft_server.jar");
            processStartInfo.UseShellExecute = false;
            processStartInfo.ErrorDialog = false;
            processStartInfo.RedirectStandardError = true;
            processStartInfo.RedirectStandardInput = true;
            processStartInfo.RedirectStandardOutput = true;
            Process process = new Process();
            process.StartInfo = processStartInfo;
            bool processStarted = process.Start();
            StreamWriter inputWriter = process.StandardInput;
            StreamReader outputReader = process.StandardOutput;
            while (!outputReader.EndOfStream)
            {
                line = outputReader.ReadLine();
                AddToLog(line);
            }
            StreamReader errorReader = process.StandardError;
        }

private void AddToLog(string text)
        {
            textBox1.Text = textBox1.Text + Environment.NewLine + text;
        }

You are not waiting for the process to end before collecting output (correctly), but if you do want all of the output you need a WaitForExit call or your code will run, exit, and stop reading. From the docs:

Code:

---

// Start the child process.
 Process p = new Process();
 // Redirect the output stream of the child process.
 p.StartInfo.UseShellExecute = false;
 p.StartInfo.RedirectStandardOutput = true;
 p.StartInfo.FileName = "Write500Lines.exe";
 p.Start();
 // Do not wait for the child process to exit before
 // reading to the end of its redirected stream.
 // p.WaitForExit();
 // Read the output stream first and then wait.
 string output = p.StandardOutput.ReadToEnd();
 p.WaitForExit();

That said, I didn't have time to test this, so I may be wrong. Sorry in advance if I am.

That may not work. If you don't constantly read from StdOut it's possible the buffer will fill up and the application will just hang until something starts clearing the stdout buffer by reading from it.

Added the WaitForExit().
No change, still have to wait for the program to exit

I think there was some confusion about what you wanted. Sounds like you are looking to get real time updates while the program is running. I personally have no idea how you would do this as I have never looked into it.
