I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This is the way to add new items :

Dim Item As ListItem

Private Sub Command1_Click()
    Set Item = ListView1.ListItems.Add(, , "Item 1")
        Item.SubItems(1) = "Item 2"
        Item.SubItems(2) = "Item 3"
        Item.SubItems(3) = "Item 4"
End Sub

Private Sub Form_Load()

    ' This part you can set in the control properties also
        ListView1.View = lvwReport
        ListView1.ColumnHeaders.Add , , "One"
        ListView1.ColumnHeaders.Add , , "Two"
        ListView1.ColumnHeaders.Add , , "Three"
        ListView1.ColumnHeaders.Add , , "Four"
End Sub

This way you can read the selected item and subitems

    ' View the main item
        MsgBox ListView1.ListItems(ListView1.SelectedItem.Index)
    ' View the sub items
        MsgBox ListView1.ListItems(ListView1.SelectedItem.Index).ListSubItems(1)
        MsgBox ListView1.ListItems(ListView1.SelectedItem.Index).ListSubItems(2)
        MsgBox ListView1.ListItems(ListView1.SelectedItem.Index).ListSubItems(3)

and make sure the selecteditem is exist, or the code may rise an error, to ensure that, add this to check whether an item is selected or not:

..
'Quit if nothing is selected
If ListView1.SelectedItem Is Nothing Then Exit Sub
..
