TreeView1.Items.AddObject(nil,'TEST',nptr); ... 我用以上程式碼產生Treeview的Treenode並將nptr連結到此TreeNode 之後用TreeView1.SaveToFile存檔，再用TreeView1.LoadFromFile讀回 請問此時該如何將原來的nptr放回原來的Treenode？ 謝謝！

Treeview will not save/load the data. You should save/load the data yourself.

I have already save/load the data myself. My question is how to assign these data back to Treenodes that were loaded back by LoadFromFile? At this time the Treenode is already there. I can not use AddObject again.

Treeview.Items.Item[index].Data := nptr;
