Treeview & Listview Catalog

Please anybody help me. I've started to make some treeview database catalog and now don't know what to do. If anybody know how to write this code ,please send me.
I want to database loads into treeview with 5 nodes, each to be child node of a previous node. Something like this:
xxxxxxxx
.....yyyyyyyyyyy
..........zzzzzzzzzzzzzzz
...............mmmmmmmmmmmm
....................ooooooooooooooooo

And when i click on the last child node, i want to list of something (for example list of mp3 music) loads from database into a listview.
I am using VB6.
Sorry because my bad english but I hope you will understand.
Please Help Me.

Well, if u tell us abt table structure then it would be easier to explain.. I hope u must have childid and parentid for each record in db. If so then add child node to refered parent node.

And on click event of node fill listview.
