Listview limit

Is there a limit to the amount of rows in a list view.

I have a routine that processes through all items in a listview correctly until it comes to index 1363 where .NET is telling me this is out of range?  Is this true?

If it is, is there anyway to get around this?

Thanks,
Paul

This sounds like an off by one bug. If you're using a loop, try setting the condition minus 1. For example:

Dim i As Integer
For i = 0 To variable - 1
...
Next

Hi Timbo,

Here is the code i'm using.  Sorry should have mentioned this earlier as there are 1612 rows inserted my listview but the following line failes at 1363 each time I run it.

LItem = listMessages.Items(i)

Code:
Dim i As Integer
            Dim LItem As ListViewItem
            Dim intIndex As Integer

            For i = 0 To listMessages.Items.Count - 1

                LItem = listMessages.Items(i)
                If LItem.Checked = True Then
                    intIndex = LItem.Index
                    txtStatus.Text = txtStatus.Text & "REMOVING: " & LItem.Text & vbCrLf

                    '## Delete Email ##
                    inbox.DeleteMessage(CInt(LItem.Text), True)

                    '## Delete from listMessages ##
                    LItem.Remove()
                End If

            Next

The problem is that every time an item is removed, listMessages.Items.Count decreases by one so eventually when the i value exceeds the number of remaining list view items, the exception is thrown.

Feel like a fool for overlooking that.. :(   It's so obvious now you have pointed it out.  Many thanks.
