Help with adding items to ListView

Maybe someone here can shed some light.

I created a Windows Mobile application with a ListView control. I want to add items to this ListView.

Code:

---

Public Class Form1

    Private Sub MenuItem4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem4.Click
        Me.Close()
    End Sub

    Private Sub MenuItem2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem2.Click
        Dim i As Short
        For i = 1 To 5
            Dim listViewItem As New ListViewItem("ItemSuccess" + i.ToString)
            listViewItem.SubItems.Add("SubItemSuccess" + i.ToString)
            ListView1.Items.Add(listViewItem)
            'listViewItem = Nothing
        Next
    End Sub

    Private Sub MenuItem3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem3.Click
        Dim i As Short
        Dim listViewItem As New ListViewItem()
        listViewItem.SubItems.Add("")
        For i = 1 To 5
            listViewItem.SubItems.Item(0).Text = "ItemFail" + i.ToString
            listViewItem.SubItems.Item(1).Text = "SubItemFail" + i.ToString
            ListView1.Items.Add(listViewItem)
        Next
    End Sub
End Class

While sub Menu2 succeeds, every run a new ListViewItem instance is created. What if the counter doesn't run to 5, but to say, 50,000?
Every new instance of the ListViewItem class generates a new instance in memory, not to mention the amount of time it will take. Even if I set the instance of ListViewItem to Nothing at the end of each run, I still lose precious cpu cycles.

So, I wrote sub Menu3. Here I create the instance outside of the loop and reuse it every time. Would be great if it worked, but it doesn't. Actually on the second run (i.e. i=2), ListView1.Items.Add(listViewItem) throws an exception, "Value does not fall within the expected range.". During debugging I found out, that the property ListView1.Index is set to "1", whereas during the first run it is set to "-1".

Does anyone have a solution to make the sub Menu3 work?

I'm not quite sure what your trying to do but i would do

Code:

---

        For i = 1 To 5
            listViewItem.SubItems.Item(i).SubItem(0).Text = "ItemFail" + i.ToString
            listViewItem.SubItems.Item(i).SubItem(1).Text = "SubItemFail" + i.ToString
            ListView1.Items.Add(listViewItem)
        Next

For not doing to much memory as you stated i would use Items.Add and SubItems.Add and use 0 to 4 instead of 1 to 5 so you can actually use the i variable
