Tree structure by Object

Fellow sufferers

Please see my (partly pseudo-) code below. I first build a tree structure and would then like to pick one branch of it and send it to a subroutine for processing. Believe the code explains what I wish to do.

BW Peter Bunde Hansen

Code:
Sub Test()
Dim inhabitants_in As Object
Dim x As Variant
Dim y As Variant
Set inhabitants_in = CreateObject("Scripting.Dictionary")
' add countries
inhabitants_in.Add "Norway", CreateObject("Scripting.Dictionary")
inhabitants_in.Add "France", CreateObject("Scripting.Dictionary")
inhabitants_in.Add "Italy", CreateObject("Scripting.Dictionary")
' add cities and number of inhabitants
inhabitants_in("Norway").Add "Oslo", 500000
inhabitants_in("Norway").Add "Bergen", 300000
inhabitants_in("France").Add "Paris", 1000000
For Each country In inhabitants_in
  
    Call country_manager(country)
    
Next country
   
End Sub

Private Function country_manager(cities_population() As Integer)
For Each city In cities_population
  
    MsgBox ("Poopulation of: " & CStr(city) & " is: " & city_population(city))
    
Next country
End Function
 

Excel Facts

Which Excel functions can ignore hidden rows?
The SUBTOTAL and AGGREGATE functions ignore hidden rows. AGGREGATE can also exclude error cells and more.
You need to look up how to loop through dictionaries:
Code:
Sub Test()
Dim inhabitants_in As Object
Dim x As Variant
Dim y As Variant
Set inhabitants_in = CreateObject("Scripting.Dictionary")
' add countries
inhabitants_in.Add "Norway", CreateObject("Scripting.Dictionary")
inhabitants_in.Add "France", CreateObject("Scripting.Dictionary")
inhabitants_in.Add "Italy", CreateObject("Scripting.Dictionary")
' add cities and number of inhabitants
inhabitants_in("Norway").Add "Oslo", 500000
inhabitants_in("Norway").Add "Bergen", 300000
inhabitants_in("France").Add "Paris", 1000000
For Each country In inhabitants_in.keys
  
    Call country_manager(inhabitants_in(country))
    
Next country
   
End Sub

Private Function country_manager(cities_population As Object)

For Each city In cities_population.keys
  
    Debug.Print "Poopulation of: " & city & " is: " & cities_population(city)
    
Next city
End Function
