How to make a list in VBA (not a dictionary)?

Question

I\'m not that familiar with VB or VBA, though I am familiar with programming.

I\'m working with Excel 2016 and trying to populate a combobox (that lives on a user form)

Answer 1

I'd like to use a data structure that offers a sort function, if one exists.

Yes exists, for example SortedList from .Net framework can be used.

SortedList represents a collection of key/value pairs that are sorted by the keys and are accessible by key and by index.

VBA code example:

Add reference to C:\Windows\Microsoft.NET\Framework\v4.0.30319\mscorlib.tlb

Sub SortedListDemo()
    Dim sr As mscorlib.SortedList
    Set sr = New mscorlib.SortedList
    sr.Add "D", "D"
    sr.Add "B", "B"
    sr.Add "A", "A"
    sr.Add "C", "C"
    Dim i As Integer
    For i = 0 To sr.Count - 1
        Debug.Print "Key: " & sr.GetKey(i) & ", Value: " & sr.GetByIndex(i)
    Next i
    Set sr = Nothing
End Sub

Output

Key: A, Value: A
Key: B, Value: B
Key: C, Value: C
Key: D, Value: D
