Question

I am trying to show text in a console launched from the click button. I think I need to input the console’s path where I have put the question marks Process.Start(“????”). How do I find the console path?

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Process.Start("????");
        Console.WriteLine("Adam");
        Console.Read();
    }
}

What you need to do is grab the console from the windows API. This will create a new instance of a console application that can output and read etc.

public partial class Form1 : Form
{
    [DllImport("kernel32.dll", SetLastError = true)]
    internal static extern int AllocConsole();

    [DllImport("kernel32.dll", SetLastError = true)]
    internal static extern int FreeConsole();

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        int alloc = AllocConsole(); // Grab a new console to write to
        if (alloc != 1)
        {
            MessageBox.Show("Failed");
            return;
            }
        Console.WriteLine("test");

        Console.WriteLine("Adam");
        string input = Console.ReadLine();
        Console.WriteLine(input);
        // Do other funky stuff

        // When done
        FreeConsole();
    }
}
