Sometimes getting multiple controls to talk nicely to each other in a Microsoft Access form can be difficult. In this example the goal is to create a form with a list box with multiple columns which the user will be able to select a company with and a combo box that will filter it’s results based on the selection in the listbox.

Imagine that you have a large file with 20 or more worksheets. It could be, for instance, a file with snapshot financial models for the companies in your coverage universe or a breakdown of home sales in different regions of the city.

You want to sort these worksheets into some kind of order that would allow you and your team to access your data more quickly. The SortSheets macro will help you to sort your sheet tabs into any kind of order or metric you want (e.g alphabetically, by ranking, etc.) using the qsort algorithm
