Something like this in form3's code:
VB Code:
  1. Dim item As New ListViewItem(form2.listview1.item(1))
  2.             ListView1.Items.Add(item)
I'm new to vb.net, more used to listviews in VB6, so that may be off some, but that's the idea. If form3 needed a value in a textbox on form2, say, you could do: strMyString = form2.txtMyTxtbox.text
