Modules & VBA :: Recursive Search And Populate Results In Tree View Control

I need some VBA coding to do the following tasks

Table 1: two columns - Child Tag and Parent Tag. Parent Tags can also be in Child Tag column. In other words, a parent can have multiple levels of children.

Table 2: one column - Backup Tag.

I'd like to have a form with a combo box, pick a Parent Tag, the search all its child tags and compare each Child Tag found with records in Table 2 to see if there is a match. Then populate all results in a tree view control.

A visual example :

Parent Tag
...Child Tag 1 - Back up tag found
......Child Tag 11
......Child Tag 12 - Back up tag found
...Child Tag 2
......Child Tag 21
...Child Tag 3
......Child Tag 31
.........Child Tag 311 - Back up tag found
