    public partial class Form1 : Form
    {

        private System.ComponentModel.BackgroundWorker bgw = null;
        private Class1 myObject1 = new Class1();

        public Form1()
        {
            InitializeComponent();
        }

        private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
        {
            if (bgw == null)
            {
                bgw = new BackgroundWorker();
                bgw.DoWork += new DoWorkEventHandler(bgw_DoWork);
                bgw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bgw_RunWorkerCompleted);
            }

            if (e.KeyChar == 13 && !bgw.IsBusy)
            {
                textBox1.Enabled = false;
                myObject1.myString = textBox1.Text;
                bgw.RunWorkerAsync();
            }
        }

        void bgw_DoWork(object sender, DoWorkEventArgs e)
        {
            myObject1.queryRecent();
        }

        void bgw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {
            label1.Text = myObject1.recentString;
            textBox1.Enabled = true;
        }

    }
