    pProcess.StartInfo.FileName = @"C:\Users\Vitor\ConsoleApplication1.exe";
    pProcess.StartInfo.Arguments = "olaa"; //argument
    pProcess.StartInfo.UseShellExecute = false;
    pProcess.StartInfo.RedirectStandardOutput = true;
    pProcess.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
