        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            i = 0;
            comboBox1.DroppedDown = false;
            string partial_name = textBox1.Text;
            comboBox1.Items.Clear();
            foreach (string s in name)
            {
                if (s.StartsWith(partial_name))
                    comboBox1.Items.Add(s);
            }
            comboBox1.DroppedDown = true;
        }

        private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            switch (e.KeyCode)
            {
                case Keys.Down:
                    if (i < comboBox1.Items.Count)
                    {
                        i++;
                        comboBox1.SelectedIndex = i - 1;
                    }
                    break;
                case Keys.Up:
                    if (i > 0)
                    {
                        i--;
                        comboBox1.SelectedIndex = i - 1;
                    }
                    break;
                case Keys.Enter:
                    textBox1.Text = comboBox1.Text;
                    comboBox1.DroppedDown = false;
                    break;
                case Keys.Escape:
                    comboBox1.DroppedDown = false;
