Getting selected item from listview

[=?Utf-8?B?TmFjaA==?=]

It works on the first selection when I want to get a different selection I get
InvalidArgument=Value of '0' is not valid for 'index'.
Parameter name: index
The Following is the code

Private Sub ListView1_SelectedIndexChanged(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
ListView1.SelectedIndexChanged
Dim SELECTEditems As ListView.SelectedListViewItemCollection =
CType(sender, ListView).SelectedItems

Dim STRCHKNUM As String
STRCHKNUM = SELECTEditems(0).SubItems(0).Text
