It is easy once you realize that there are two ways to put in a subitem.
Listview1.ListItems(2).SubItems(1) = "addsubitem" is the easiest, but no way to add an icon.
Listview1.ListItems(1).ListSubItems.Add , , "addsubitem", 1 will do it. the Add method gives
several options that the other syntax doesn't, but other than that, they both work equally well.
