You could try making the TreeCtrls large enough that they don't need to 
display their scrollbars, and then respond to the scroll events from the 
DSW by moving the tree widgets such that the portion that is visible 
(not clipped by their parent) corresponds to the scrollbar positions.  I 
think I would approach it by using a custom panel to hold the treectrl 
and manage sizing it and positioning it.  You can then give it 
Set[V|H]ScrollBar methods like STC so it can hook itself up to the DSW's 
scrollbars.
