[RESOLVED] [2005] search an object in a listbox

[lplover2k]

i have a class "item" and this is how my class looks and how i populate" item"objects my listbox list1

public class item
 
 Public fname As String, pid As Long
 
        Public Sub New(ByVal id As Long, ByVal nm As String)
            fname = nm
            pid = id
        End Sub
 
        Public Overrides Function ToString() As String
            Return pid & vbTab & fname
        End Function
end class
 
 Private Sub form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles form1.Load
     list1.items.add(new item(1,"myname"))
    End Sub

my question is how can i search for a particular object in the list provided my search criteria is the id ???
