[AccessD] Recursive data in treeview control

Hiya

Does anyone have any code for recursively populating a treeview control? I
have a table like this:

TaskID		ParentID	Description
1		0		fleg
2		1		subfleg a
3		1		subfleg b
4		2		sub-subfleg a

and so on. I don't want to limit the number of levels.

I can see that I need to run through the dataset and populate the treeview
with the first level, then do it again n times until all the children are
added at the appropriate level, skipping any record already added as a node.

I'm in a hurry - I have 2 hours to nail this (working hours not real-time)
so although it feels lazy and I would love to crack this on my own, if
anyone has done it before I would appreciate any help you can give.

TIA
