Answer 1

extern CTreeCtrl* pmyTreeCtrl;
// The item whose children will be deleted.
extern HTREEITEM hmyItem;// Delete all of the children of hmyItem.
if (pmyTreeCtrl->ItemHasChildren(hmyItem))
{
   HTREEITEM hNextItem;
   HTREEITEM hChildItem = pmyTreeCtrl->GetChildItem(hmyItem);   while (hChildItem != NULL)
   {
      hNextItem = pmyTreeCtrl->GetNextItem(hChildItem, TVGN_NEXT);
      pmyTreeCtrl->DeleteItem(hChildItem);
      hChildItem = hNextItem;
   }
}
