I am trying to gather the values of a ListView control into variables on the selection_changed event but am getting an error. The code is as follows:

        Dim s1 As Object
        Dim s2 As Object
        Dim s3 As Object

        Dim SelInd As Object = Me.lsbAnchor.SelectedIndices(0)

        s1 = Me.lsbAnchor.Items(SelInd).SubItems(0).Text
        s2 = Me.lsbAnchor.Items(SelInd).SubItems(1).Text
        s3 = Me.lsbAnchor.Items(SelInd).SubItems(2).Text

The error that I am getting is on the line
"Dim SelInd As Object = Me.lsbAnchor.SelectedIndices(0)"
The error is as follows
InvalidArgument=Value of '0' is not valid for 'index'.
Parameter name: index

Try assigning SelInd a value in the ListBox_Load event. I think what's happening is that you're trying to grab a value out of the listbox before it's being populated.

@That's because the event fires twice. Once for the item being selected, and once for the item that is no longer selected. Just check the SelectedItems.Count for > 0 before perforrming any operations on the first item in the collection.
