,,,But can U explain the 4th parameter in particular..

// find root
HTREEITEM hRoot = pCtrl->GetRootItem();//pCtrl is CTreeCtrl pointer

if (hRoot == NULL)

I have the handle to the tree view and not a pointer

CTreeCtrl *pTreeCtrl = dynamic_cast<CTreeCtrl*> (CWnd::FromHandle(hWndYouHave));

dynamic cast was not required
This is enough:
CTreeCtrl* pCtrl = (CTreeCtrl*)(CWnd::FromHandle(HandleToTreeView));
