I've had a heck of a time finding a good example to do some simple appending to a ListView in ReportView mode. I finally figured it out (for a database search result form) so if anyone else has had the trouble ive had... here ya go!
Code:
With ListView1.ListItems.Add()
   .Text = "Column 1"
   .SubItems(1) = "Column 2"
   .SubItems(2) = "Column 3"
End With
ListView1.View = 3 ' lvwReport
ListView1.FullRowSelect = True
