    It's also completely broken for odd-length lists (due to the unchecked fastCursor.next.next). Please edit the question to include your test set.

fastCursor = fastCursor.next.next; will crash if the number of nodes in the list is even (but greater than zero).

Function to Return a JSON Like Objects Using VBA Collections and Arrays

Image
Clash Royale CLAN TAG #URR8PPP .everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty margin-bottom:0; up vote 1 down vote favorite My goal is to create a compact function that can create a JSON Like object from JSON string. I want a function with a small footprint that I or anyone who wants to use it, can simply paste into a module and use. At 61 lines of code, I am happy with its size and portability. Here is an image of JSON Object created from string data using a ScriptControl . Although the Locals Window displays the properties and values correctly, the object itself is extremely difficult to work with. This image shows an object created using getJSONCollection . Because it is made of VBA Collections and Arrays, it is very easy to work with. Option Explicit Private Function getJSONCollection(ByVal Value As Variant, Optional ScriptEngine As Object) As Variant Const DELIMITER As String = "||" Dim col As Collection, JSON As Object, KeyNam

Will my employers contract hold up in court?

This contract seems incredibly binding, 2 years in length, and I’m looking to see if it would actually hold up in an Arizona court. contract employment non-compete arizona share | improve this question edited Aug 7 at 15:35 feetwet ♦ 13.8k 9 37 85 asked Aug 6 at 19:05 Alex S. 46 2 What does your company do and what services do they provide?
