i want to remove single items from list and want to keep duplicate items in listbox

You mean just remove selected item?

noooooooooooooooooooooooo i want to make inverse of duplicate remover

i want to keep save multi items save in list box and remove single items

The answer is still the same, once you have identified the offending entry

ListBox1.Items.RemoveAt(IndexOfSingleItem)

i want to make application same as duplicate remover but it dose not remove duplicates it remove single items and keep duplicate , it identify single item him self , i dnt want to select 15000 items

so i think to make inverse of duplicate remover

hello honeybee2090!

here is simple code to perform same action ,

'use this code at you button click event 
   Dim i As Integer
        Dim x As Integer
        Dim no As Integer
        Dim rec As New ArrayList
        For i = 0 To ListBox1.Items.Count - 1

            no = 0
            A = ListBox1.Items(i).ToString
            For x = 0 To ListBox1.Items.Count - 1
                B = ListBox1.Items(x).ToString
                If A = B Then
                    no = no + 1
                    If no >= 2 Then
                        MsgBox("duplicate record=" & B)
                        Exit For
                    End If
                End If
            Next



            If no < 2 Then
                rec.Add((ListBox1.Items(i)))
            End If
        Next
        Dim ab As Integer
        For ab = 0 To rec.Count - 1
            ListBox1.Items.Remove(rec.Item(ab))
