Transforming Two Collections into a Dictionary in VBA

If you're working with Visual Basic for Applications (VBA) and need to combine two collections into a dictionary, you've come to the right place. The task may seem daunting at first, especially if you're trying to understand how to set the items in the dictionary while looping through your collections. Let's break down the problem and find a straightforward solution.

Understanding the Problem

You have two collections:

rembs: This collection will be used as the keys in your dictionary.

cols: This collection will serve as the values (or items) associated with the keys.

You want to store these key-value pairs in a dictionary called pairs. The challenge arises when you're unsure how to set the items in the dictionary while looping through your collections.

The Solution

Let’s walk through the steps necessary to accomplish this task effectively.

Step 1: Initialize Your Collections

First, you need to populate your two collections (rembs and cols):

Step 3: Populate the Dictionary

Now it’s time to fill the dictionary with data from your collections. You can do this by looping through your rembs collection and assigning cols values directly:
