Visual Studio 2010 - Count Listbox Items While Running A For Each Loopt?

I have a list of links and need to check some data in it.

i placed all the list in a listbox and each item is verified for some result

now i want to see how many items are processed and how many are still need to process

Example: in a label it must display total count of items and items completed and it must change once a item is finished.

over view of my code is:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
For Each item In ListBox2.Items

[Code]....

Once an item is finished label must change the count.
