Answer 1

Let's say that your worker method (that you execute in a thread) is

DoWork(args)
{
    ...
    UpdateUI();
}

The method that handles timer's Elapsed event should do this:

OnTimerElapsed(object sender, ElapsedEventArgs e)
{
    args = GetArgs();
    this.BeginInvoke(() => DoWork(args));
    // 'this' refers to form here.
    // You can also use BeginInvoke on a user control for updating it.
}

This will run DoWork in a seperate thread and DoWork will have the ability of updating UI.

Answer 2

 formObject.Invoke(delegate { 
      // action to perform on UI thread
 });
