    public partial class frmLock : Form
    {
        int IntNum = 0;
        int IntWait = 60;
        string StrPassword;

        public frmLock()
        {
            InitializeComponent();
        }

        private void txtLock_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyData == Keys.Enter)
            {
                if (txtLock.Text == "/setpassword")
                {
                    StrPassword = InputBox("New password to use:", "Password", "/unlockit");
                }
                else if (txtLock.Text == StrPassword)
                {
                    this.Close();
                }
                else if (txtLock.Text == "/0ver")
                {
                    this.Close();
                }
                else
                {
                    if (IntNum >= 5)
                    {
                        MessageBox.Show("You have been blocked for to many unblock attempts", "Haha!");
                        txtLock.Enabled = false;
                        tmrWait.Enabled = true;
                    }

                    IntNum = IntNum + 1;
                    lstFail.Items.Add("[" + IntNum + "] - Failed unblocked; Incorrect password");
                }
            }
        }

        private void tmrTop_Tick(object sender, EventArgs e)
        {
            this.TopMost = true;
        }

        private void tmrWait_Tick(object sender, EventArgs e)
        {
            IntWait = IntWait - 1;

            if (IntWait <= 0)
            {
                tmrWait.Enabled = false;
                txtLock.Enabled = true;
                MessageBox.Show("Try again");
                lstFail.Items.Add("[0] - now able to try to unblock the screen again. Don't fail.");
            }
        }

        public static string InputBox(string prompt, string title, string defaultValue)
        {
            InputBoxDialog ib = new InputBoxDialog();
            ib.FormPrompt = prompt;
            ib.FormCaption = title;
            ib.DefaultValue = defaultValue;
            ib.ShowDialog();
            string s = ib.InputResponse;
            ib.Close();
            return s;
        }
    }
} 
  

And of course, the class for the inputbox:

   public static string InputBox(string prompt,
    string title, string defaultValue)
  {
    InputBoxDialog ib = new InputBoxDialog();
    ib.FormPrompt = prompt;
    ib.FormCaption = title;
    ib.DefaultValue = defaultValue;
    ib.ShowDialog();
    string s = ib.InputResponse;
    ib.Close();
    return s;
  } // method: InputBox

Though it may be a bit boring, in case you may want the code, it is shown in Figure 3 and can be copied from this page to your blank class.
