The online Help file entry on TListView does not indicate that there is a property like SelectedItems. This is true also for TRzListView.

Here is a simple example which tests the ListItem property Selected in order to extract your guideline data from multiple selected items (assume MultiSelect = True) and displays them in a message box:

  '-------------------------------------------------------------------------------
  dim I
  dim iArea, iGuideline, iNum
  dim iText

  with CDIP_FRM.ListView.Items
    iText = "Selected Items:" & vbNewLine
    for I = 0 to .Count - 1
      if .Item(I).Selected then
        iArea = .Item(I).Caption
        iGuideline = .Item(I).SubItems(1)
        iNum = .Item(I).SubItems(0)

        iText = iText & vbNewLine & iNum & vbTab & iArea & vbTab & iGuideline
      end if
    next
  end with

  msgbox iText
  '-------------------------------------------------------------------------------

I hope this helps.
