You aren't adding the items to the combo box, you're only setting its Text property. That's only changing the text currently displayed in the combo box, and only one item can be displayed at a time.

If you want the items to be permanent and selectable, you need to add them to the combo box control's Items collection.

Sample code:

If CheckedListBox1.CheckedItems.Count > 0 Then
    For Each checkedItem In CheckedListBox1.CheckedItems
        cbCheckedItem.Items.Add(checkedItem.ToString())
    Next
End If

Or, better yet, use the AddRange method:

If CheckedListBox1.CheckedItems.Count > 0 Then
    Dim checkedItems() As String = CheckedListBox1.CheckedItems.Cast(Of String).ToArray()
    cbCheckedItems.Items.AddRange(checkedItems)
End If
