Hi Doriano,

PUBLIC SUB Button2_Click()

 IF NOT TreeView1.MoveFirst() THEN
    REPEAT
      'do things with the current item
       'xxx.item.xxx()   
      'TextArea1.Text &= TreeView1.Item.Key()
      ' NOT AN OBJECT ! 
      TextArea1.Text &= TreeView1.Item.Key & "\n"
      'give just the root-childs
    UNTIL TreeView1.MoveNext()
  ENDIF

END

I got only the root-childs with this code but i think 
it should be possible with additional treeview.item.count and 
treevie.item.children loops. 
I presumed the trreview holds the items in a collection and
the collection objects are accessible via FOR EACH IN.
