I have been through the forum and I have seen many examples of listview sorting but In this one instance I can't get it to work.
I am loading a Listview from dbf file if the item found in the db meet the criteria it is added to the listview. No problem I get a full listview of items I wanted. Now the first column is time in the 24 hour format. So I want to sort the column accending, (00:00:00 ==> 24:59:59) I have a class for the listview Item comparer that looks like this.
and is called like this
but I still get a couple of entries out of wack. The first column will look like this.
00:00:00
01:00:00
12:00:00
20:00:00
17:00:00
23:00:00
This will stay this way even if I call the sort after the Listview is done being loaded. Also If I add a new item to the db it'll be placed at the bottom and not sorted. I have stepped through the code but nothing sticks out.
Any thoughts?
Thanks

Visual Basic:
Public Class ListViewItemComparer
Implements IComparer
Private col As Integer
Public Sub New()
col = 0
End Sub
Public Sub New(ByVal column As Integer)
col = column
End Sub
Public Function Compare(ByVal x As Object, ByVal y As Object) As Integer _
Implements IComparer.Compare
On Error Resume Next
Return [String].Compare(CType(x, ListViewItem).SubItems(col).Text, CType(y, ListViewItem).SubItems(col).Text)
End Function
End Class
Visual Basic:
lv.ListViewItemSorter = New ListViewItemComparer(1)
lv.Sort()
but I still get a couple of entries out of wack. The first column will look like this.
00:00:00
01:00:00
12:00:00
20:00:00

23:00:00
