Uncheck child nodes if parent node is unchecked in treeview

I'm trying to use a Treeview control. I'd like to have all child nodes be
automatically unchecked if a if I uncheck a parent node. Also, is there a
way to specify that if a node contains child nodes it'll automatically be
bold?

I've got drag 'n drop working on my treeview and so I'd like any parent
nodes to bold themselves.

I would love it if someone could help me with this. Even better; does
anyone know a really, really good and simple to understand novice to advanced
tutorial on how to program treeview controls? This would help prevent me
from bugging everyone about my treeview woes.
 
1. You need to iterate the collection of children of the node being unchecked and uncheck each of them individually.

2. Yes, of course. 'Or' TVIS_BOLD constant to item style when adding it's children. Check Object Browser ([F2] key in VB) to see VB equivalents of TVM_SETITEM message (probably some method of TreeNode(?) object) and TVIS_BOLD constant (=&h10=16).
 
Could you explain a little more about your number 2 line? Is that supposed
to make any parent node bold if it contains child nodes? How would I use
that? Which event would I put that in?
