  private void btnGuess_Click(object sender, EventArgs e)
        {
            if (lblRemember.Text == txtAnswer.Text)
            {
            
                MessageBox.Show("Correct");
                 newhscrollbar.Value = 341;
                newhscrollbar.Maximum = 345;
                newhscrollbar.Minimum = 0;
               //Other condition
                txtAnswer.Clear();
                txtAnswer.Focus();
                Generator();
                lblRemember.Show();
                lblLevel.Text = (int.Parse(lblLevel.Text) + 1).ToString();//increase level
                Generator();
                txtAnswer.Enabled = false;
