No, in Gambas, a Collection is a hash table and not a set (which is what
Java seems to have). You do:

  cCollection["key"] = value ' value is a Variant

Yeah, should work... But you are doing it wrong in your code given. You can
do the following: create a String[] aResult or something. Then use the
hresult["whatever_id"], converted to an Integer, as index:

  aResult.Add(hresult["payload"], CInt(hresult["whatever_id"]))

Later, return that String[] as you do.

Then, when filling the ComboBox, all the elements you didn't assign anything
to (the missing "whatever_id"'s will be Null):

  Dim aResult As String[] = GetTheResultArray()
  Dim iInd As Integer

  For iInd = 0 To aResult.Max
    If Not aResult[iInd] Then Continue
    myComboBox.Add(aResult[iInd], iInd)
  Next

Whether this works (your question below) or how it will look like if some
indices in the ComboBox are missing, I don't know. Test it!
