Answer 1

See this answer here on SO which I posted code for a process to exec netstat an redirect the output stream to a Stringbuilder instance. The process creates a hidden window and is not visible...

You can modify the code slightly by changing the values respectively

ps.CreateNoWindow = true; <--- Comment this out...
ps.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; <--- Comment this out...

Answer 2

you can easily catch all messages using

Process build = new Process();
...
build.StartInfo.UseShellExecute = false;
build.StartInfo.RedirectStandardOutput = true;
build.StartInfo.RedirectStandardError = true;
build.StartInfo.CreateNoWindow = true;
build.ErrorDataReceived += build_ErrorDataReceived;
build.OutputDataReceived += build_ErrorDataReceived;
build.EnableRaisingEvents = true;
...

and create the Event build_ErrorDataReceived

static void build_ErrorDataReceived(object sender, DataReceivedEventArgs e)
{
    string msg = e.Data;
    if (msg != null && msg.Length > 0)
    {
        // in msg you have the line you need!
    }
}
