Now, when I run this code, it throws this exception: Action being performed on this control is being called from the wrong thread. Marshal to the correct thread using Control.Invoke or Control.BeginIn voke to perform this action.
If you can explain to me how to properly use the BeginInvoke or Invoke methods or explain how to fix this to get it to work. Thanks. :)
