Background Worker and Timer

Hi,

I am trying to write this application. Currently I have a BackgroundWorker thread to do some operation. Inside the worker thread, I have this loop to do the work n amount of times and also a delay time in which I used to pause the loop.

Currently it looks something like this

 bg_DoWork(object sender, DoWorkEventArgs e)
{ ......
  repeat = 10;
  int i = 0;
  int delay = 5;

  while ( i < repeat)
  {  //do some work 
      i++;
      //pause for n seconds
      System.Threading.Thread.Sleep(delay*1000)
  }

This works fine. However, I want have a timer to count down or up during the delay duration, in the UI thread. I tried creating a timer in the background thread but the tick event won't invoke because it is not in the UI thread. What is the best way of doing this?

Thank you,
dbzx
