How can I subclass the scrollbar inside a CListCtrl or a CTreeCtrl.  The method GetScrollBarCtrl returns NULL. My lists and tree are very nice but I'm stuck with ugly gray scrollbars. I only I could get a hold on it...

From my limited experience (it's also been a while...), you have to implement your own... and draw them on top of those grey ones... It's a nice hack, but then again, what isn't in windows...

"That custom scroll bar would then relay the scroll messages directly to treectrl. We also had to implement all the displays of the scrollbar (thumb, buttons, etc.)"

I'll try to find my old stuff and mail some useful info from it to you...
