How i can pause/resume a thread in window form application ?

[Husnul karim]

I am developing an window form application, in which i am playing an audio of wave format, and want to convert that pre recorded speech or audio into text format(using speech api) and display that text in the label. I started a thread for audio to text conversion in the play button, now i want to pause that thread on the pause button(means how to pause a that thread). I used ManualEventReset method. but in the pause button when i am using signal.waitone() methods. this freez the whole form. please help.some parts of my code is given here. //pause button

 ManualResetEvent signal = new ManualResetEvent(false);

 ManualResetEvent signal = new ManualResetEvent(false);

private void buttonX15_Click(object sender, EventArgs e)
{
method_pause();
}

public void method_pause()
{

       clip.Pause();
       visular1.Stop();
       visular2.Stop();
       visular3.Stop();
       visular4.Stop();
       visular5.Stop();
       this.pause.Hide();
       signal.WaitOne();
       play.Show();
   }

private void play_Click(object sender, EventArgs e)
{

      playsub();
      labelX1.Text = "Play";
   }

public void playsub()
{
starter = delegate { subt(FName); };
thread=new Thread(starter);

        try
        {
            thread.Start();
            method\_play();

        }
       catch(Exception ex){}

   }

from where i can set the thread.

You haven't posted all your code and it looks, to me, that you are starting the video through your method_play method, which is happening on the primary thread.
