Lists in VBScript

Question

I'm trying to create a simple list in a VBscript, but I'm unable to find something similar.

Basically, I'm working on Active directory, and I need to get all the groups a user is a member of for all the users within a domain. Now, every user might be a member of a different number of groups, so I plan to use a dictionary, with the key being the SAMID for the user, and the value being a list of all the groups he/she is a member of.

I can do this with a static array, but then I have to declare a random large size for the array which is not nice. What I would ideally like to do is have a python-like list, where I can simple do something like myList.Add and don't have to worry about sizing.

I tried using System.Collection.ArrayList, but I get an error when I run it:

PS C:mp> cscript.exe .foo.vbs
Microsoft (R) Windows Script Host Version 5.8
Copyright (C) Microsoft Corporation. All rights reserved.

C:mpfoo.vbs(1, 1) (null): 0x80131700

how can I accomplish this?

Answer 1

Get rid of the dictionary and unleash the power of an ArrayList.

Option Explicit

dim list
Set list = CreateObject("System.Collections.ArrayList")
list.Add "Banana"
list.Add "Apple"
list.Add "Pear"

list.Sort
list.Reverse

wscript.echo list.Count                 ' --> 3
wscript.echo list.Item(0)               ' --> Pear
wscript.echo list.IndexOf("Apple", 0)   ' --> 2
wscript.echo join(list.ToArray(), ", ") ' --> Pear, Banana, Apple

EDIT: I see you already tried the ArrayList, but got an error. It seems your installation of the dotnet framework is not correct (System.Collections.ArrayList is part of that). Microsoft has an article about how to solve that: http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/error-code-0x80131700/3add8d80-00e0-4355-a994-8630d01c18f5
