无法显示treeview根节点项文本mfc？

我有一个树控件，我用两个节点启动了树控件，其中两个项由子节点组成。我在对话框中添加了一个按钮，现在当我单击任何根节点并单击此按钮时，我必须复制现有节点，即复制现有节点

我可以复制它并显示重复的数据。这里正好出现了我的问题，即我无法看到复制的根节点文本，但我可以看到子节点，唯一的问题是根节点无法显示文本

                            hFirstSubChild = hNextSibilingItem;

                        }

                    }

                }
                hPsChildItem = m_TreeCtrl.GetNextSiblingItem(hFirstChild);
                hFirstChild = hPsChildItem; 

            }

            ::UpdateWindow(m_TreeCtrl.GetSafeHwnd());

        }

    }


}

这就是我添加副本的方式。例如，在我的树中，第一个节点是XXX，现在我单击“添加”按钮，树控件将获得另一个项目，如XXX2，依此类推。。像这样

在我的场景中，当我第一次添加时，我得到的是空的东西作为节点，并且能够得到子节点。现在，如果我现在单击添加，我得到的是XXX2，然后再次添加XXX3

我不知道为什么调试时无法获取文本，因为它显示文本，但未设置文本

任何人都可以告诉我哪里做错了。

尝试将szDuplicateItem从指针更改为WCHAR数组WCHAR szDuplicateItem[_MAX_PATH]；并从szSelectedItemText复制值。已更改，但仍不起作用。它就是这样来的。
