Answer 1

I add functions like the following so that I can add items to the list box from either the main thread or background threads. Thi thread checks if a Invoke is necessary and then uses Invoke if it is necessary.

  delegate void AddListItemDelegate(string name,object otherInfoNeeded);

  private void
     AddListItem(
        string name,
        object otherInfoNeeded
     )
  {
     if (InvokeRequired)
     {
        BeginInvoke(new AddListItemDelegate(AddListItem), name, otherInfoNeeded
        return;
     }

     ... add code to create list box item and insert in list here ...
  }
