 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim lCount As Integer
        If ListView1.SelectedItems.Count > 0 Then
            For lCount = 0 To ListView1.Items.Count - 1
                If ListView1.Items(lCount).Selected Then
                    MsgBox(lCount.ToString)
                End If
                Application.DoEvents()
            Next
        End If
    End Sub
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim lCount As Integer
        If ListView1.SelectedItems.Count > 0 Then
            For lCount = 0 To ListView1.Items.Count - 1

    End Sub
 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim lCount As Integer
        Dim lvitem As ListViewItem

        For lCount = 1 To 3
            lvitem = ListView1.Items.Add(lCount)

ListView1.SelectedItems(1).BeginEdit() cant worrk out. You have multiselect set to false so there is always only one item selected. so it have to stick on 0.
remember ListView1.SelectedItems(1) doesnt mean its the next item in list, its the next selected item (which doesnt exist on multiselect=False)

1) since multiselect is false
listview1.selecteditems(1) is not possible
it has to be listview1.selecteditem(0)
since u want a particular column add another parameter.
listview1.selecteditem(0)(1)
this should fetch the second row.
this is just like a 2 dimensional array or a matrix.
first parameter is the row and the second parameter is the column
