            using (Process sortProcess = new Process())
            {
                sortProcess.StartInfo.FileName = @"C:\Users\Nico Travassos\Desktop\Minecraft\Minecraft CROSS Server\RUN.bat";
                sortProcess.StartInfo.CreateNoWindow = true;
                sortProcess.StartInfo.UseShellExecute = false;
                sortProcess.StartInfo.RedirectStandardOutput = true;

                // Set event handler
                sortProcess.OutputDataReceived += new DataReceivedEventHandler(SortOutputHandler);

                // Start the process.
                sortProcess.Start();

                // Start the asynchronous read
                sortProcess.BeginOutputReadLine();

                sortProcess.WaitForExit();
            }
        }
        void SortOutputHandler(object sender, DataReceivedEventArgs e)
        {
            Trace.WriteLine(e.Data);
            this.BeginInvoke(new MethodInvoker(() =>
            {
                richTextBox1.AppendText(e.Data ?? string.Empty);
            }));

Solution 1

where is

craftbukkit-1.6.4-R1.0.jar

in relation to your exe ? no, thats badly phrased - how will the jre know where to find that jar - is it on your CLASSPATH, or, have you specified a CLASSPATH in your java.exe run statement for-instance ?

The commonest mistake I see where people are starting 'processes' is they assume the environment is as they see it when they are logged on - and unless you're actually forcing the process to be run under a different profile, and that profile has everything set up correctly, thats usually not the case

craftbukkit-1.6.4-R1.0.jar is inside folder if you click run.bat it runs craftbukkit-1.6.4-R1.0.jar creating the server it works fine if i click it but if i click start in my gui it does not work the same

which folder ? if you mean "C:\Users\Nico Travassos\Desktop\Minecraft\Minecraft CROSS Server\" I still dont see anything there that either sets the CLASSPATH or sets 'the execution context' to that folder ... you're making too many assumptions about the process you're starting

Does it work if you add

c:
CD "\Users\Nico Travassos\Desktop\Minecraft\Minecraft CROSS Server"

as the very first 2 lines to run.bat ?OR ... see if using/adding

sortProcess.StartInfo.WorkingDirectory="C:\Users\Nico Travassos\Desktop\Minecraft\Minecraft CROSS Server\";

to the process params/startup helps

Maby this helps you ^^
Make a textbox and name it: "serverlog" for output data from server
Make a textbox and name it: "msgtb" to write commands to server
Make a button and name it: "Startbt" to Start the server
Make a button and name it: "Stopbt" to stop the server
