VB.NET Remove Item in ComboBox after placing in Listview

I want to remove item from Combobox after using it in Listview

I fill combobox in Form_load with:

With CmbCode
.items.clear
For N 1 to 9999
.items.add(N)
Next
End With

Here I need Something to remove the Used numbers From Combobox (CmbCode) I use a library Class To fill the listview:

Dim Formatter As New BinaryFormatter
Dim AL As New ArrayList
ReadFile.Seek(0, SeekOrigin.Begin)
AL=CType(Formatter.Deserialize(ReadFile), ArrayList)
Dim itm As Object
For Each itm In AL
Lsv1.Itmes.Add(itm)
Next
ReadFile.Close
Formatter = Nothing

I have no idea how to remove the used numbers (In Listview) from the combobox. Any Idea how to approach the problem.

Don't use that loop when loading. Call Items.AddRange to add all the items in one go. If you keep the items that you have previously removed in a list then you can easily exclude those when loading, e.g.

Dim items = Enumerable.Range(1, 9999).Except(previouslyRemovedItems).ToArray()

CmbCode.Items.AddRange(items)

I haven't tested that and it might be that AddRange will not accept a value-type array, so you may need to cast as type Object, i.e.

Dim items = Enumerable.Range(1, 9999).Except(previouslyRemovedItems).Cast(Of Object)().ToArray()
