Catch WM_LBUTTONDOWN and check state before and after. Same for WM_KEYDOWN:

void CTreeViewCtrl::OnLButtonDown(UINT nFlags, CPoint point)
{
CTreeViewNode* pItem = 0;
BOOL bChecked = FALSE;

if (m_bCheckboxes)
{
  UINT nFlags;
  HTREEITEM hItem = GetTreeCtrl()->HitTest(point, &nFlags);
  if (hItem && (nFlags & TVHT_ONITEMSTATEICON))
  {
   pItem = GetItem(hItem);
   bChecked = GetTreeCtrl()->GetCheck(hItem);
  }
}

COleControl::OnLButtonDown(nFlags, point);

if (pItem && (pItem->OleGetChecked() != bChecked))
{
FireNodeCheck(pItem->GetIDispatch(FALSE));
}
}
