Is there a way to get the root item handle from one of its children?

I usually store the parent's handle as the child items user data (SetItemData), which allows for quick traversal back up the tree.

Or you can use the API to get it:

#define TV_FIRST 0x1100
#define TVM_GETNEXTITEM         (TV_FIRST + 10)
#define TVGN_PARENT             0x0003
DECLARE IMPORT,SendMessageA(hwnd as UINT,uMsg as UINT,wParam as UINT,lParam as UINT),UINT;

sub GetParentItem(UINT hTreeView,UINT hChildItem),UINT
     return SendMessageA(hTreeView, TVM_GETNEXTITEM, TVGN_PARENT, hChildItem);

Sorry, You asked for the root.  You can use the same method but change TVGN_PARENT to TVGN_ROOT:

#define TVGN_ROOT               0x0000
