Matty and I made a tree-view class some time ago. The code isn't very beautiful and properly could use a rewrite, but it should be readable enough to understand how it works.
Basically, to add an item you send a TVM_INSERTITEM message with a TVINSERTSTRUCT. To change an item you send a TVM_SETITEM message with a TVITEM structure.
