Here's my scenario. I'm displaying the contents of the windows computer's directories in a CTreeCtrl. Ok, fine easy. There are certain things that I need that cannot be stored in CTreeCtrl. I need a model that holds the data externally. Enters CDirNode.
Ok, first question. Right now CDirNode is in a linked list. This list is traversed VERY often. You think there'll be a big boost in speed if I implement a binary search tree instead (based on the values of HTREEITEM member)?
Second, the only problem I can't figure out is with CTreeCtrl's check boxes. Previously I processed the NM_CLICK notification and checked to see which boxes were checked. It would REALLY be nice to have a notification just when the user checks that damn box. Is there something like that? I checked and the docs didn't say much about notifications for change of state of item, which I know are present in other controls.
