Ive been working on this for sometime now

I keep getting errors.

All I want to do is fill the combo box from the arraylist

It is a 1 dimensional array called al
combobox is val_list


 Dim al As ArrayList
        al.Add("myval")
        al.Add(14343)


I can get it to show when the program loads but I get array errors when I try:
Protected Overrides Sub OnLoadSettings()
        ' Let mybase do its thing...
        MyBase.OnLoadSettings()
 
 Dim al As ArrayList
        al = CType(UserPreferences.GetPreference("ARRAYLIST", al), ArrayList)
        If al Is Nothing Then
            Console.WriteLine("Did not get ArrayList!")
        Else
            Console.WriteLine("Retrieved the ArrayList!")
            Dim i As Integer
            For i = 0 To al.Count - 1
                Console.WriteLine("  " & i.ToString & ": " & al.Item(i).ToString)
            Next
        End If

   
 to bind it the combo
or
fill the combo

Im losing my hair!!!!!

  Private Sub FillItems(ByVal cmb As ComboBox)
            cmb.DisplayMember = "MYArrayList:"
           for i = 0 to Arraylist.Count -1
            cmb.Items.Add(ai(i))

sorry: forgot to remove [ cmb.DisplayMember = "MYArrayList:"]

Dim al As ArrayList
        al.Add("myval")
        al.Add(14343)


  Private Sub FillItems(ByVal cmb As ComboBox)
            for i = 0 to Arraylist.Count -1
            cmb.Items.Add(ai(i))
            next
 End Sub

It still is not working

my combobox is called fav_list

 I tried this.


    Private Sub FillItems(ByVal cmb As ComboBox)

        Dim i As Integer
        For i = 0 To al.Count - 1
            fav_list.Items.Add(al(i))
        Next
    End Sub

and this under form load

fav_list.Items.Add(FillItems)
