God I got really bored and decided that I haven't messed around in C# for a bit that I'd make something really simple. This is not recommended.
Also to show some other programmers that if they wanted to move onto visual C# what it would look like a little.

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Windows.Forms;



namespace PasswordProtectoin

{

    public partial class frmMain : Form

    {

        public frmMain()

        {

            InitializeComponent();

        }



        private void frmMain_Load(object sender, EventArgs e)

        {



            if (txtPassword.Text == "YOURPASSWORD")

            {

                MessageBox.Show("Access granted!", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);

            }

            else

            {

                MessageBox.Show("Access denied!", "Denied", MessageBoxButtons.OK, MessageBoxIcon.Information);

            }

        }

    }

}
