If there is no tree control item selected at the time then that is correct. You should capture the treeitem when it gets selected.

Solution 1

From the documentation: "CTreeCtrl::GetSelectedItem"[^], it looks you are trying to retrieve the selected item of a TreeCtrl (instead of a ComboBox), and such operation is failing.
