How do I hide a console application user interface when using Process.Start?

Question

I want to run a console application that will output a file.

I user the following code:

Process barProcess = Process.Start(\"bar.exe\", @\"C:\\foo.txt\")         


        

Answer 1

If you would like to retrieve the output of the process while it is executing, you can do the following (example uses the 'ping' command):

var info = new ProcessStartInfo("ping", "stackoverflow.com") {
    UseShellExecute = false, 
    RedirectStandardOutput = true, 
    CreateNoWindow = true 
};
var cmd = new Process() { StartInfo = info };
cmd.Start();
var so = cmd.StandardOutput;
while(!so.EndOfStream) {
    var c = ((char)so.Read()); // or so.ReadLine(), etc
    Console.Write(c); // or whatever you want
}
...
cmd.Dispose(); // Don't forget, or else wrap in a using statement

We have done this in the past by executing our processes using the Command Line programatically.

        Process p = new Process();
        StreamReader sr;
        StreamReader se;
        StreamWriter sw;

        ProcessStartInfo psi = new ProcessStartInfo(@"bar.exe");
        psi.UseShellExecute = false;
        psi.RedirectStandardOutput = true;
        psi.RedirectStandardError = true;
        psi.RedirectStandardInput = true;
        psi.CreateNoWindow = true;
        p.StartInfo = psi;
        p.Start();

This will start a child process without displaying the console window, and will allow the capturing of the StandardOutput, etc.

Check into ProcessStartInfo and set the WindowStyle = ProcessWindowStyle.Hidden and the CreateNoWindow = true.
