How to reslove it?

There is one function which is listening.
I want it to be run continuously and rest of the program should also be fully operatable.
How can i do it?

you can make it call itself and run it on a seperate thread.

this code keeps checking if a checkbox is checked and terminates the thread if it isn't.

Code:

---

        private void button1_Click(object sender, System.EventArgs e)
                {
                        System.Diagnostics.Debug.WriteLine("startthread");
                        Thread t = new Thread(new ThreadStart(threader));
                        t.Start();
                }

                private void threader()
                {
                        Thread.Sleep(100);
                        if (this.checkBox1.Checked)
                        {

                                threader();
                        }
                        else
                        {
                                System.Diagnostics.Debug.WriteLine("stop");
                        }
                }
