Hello,

I use CXTEditListBox and in the ItemData i store a pointer to a struct.
i've subclass CXTEditListBox
in ON_WM_DELETEITEM_REFLECT()
DeleteItem() i delete the struct.

But if i rename a item, the OnEndLabelEdit function call
            DWORD_PTR dwData = GetItemData(m_nIndex);
            DeleteString(m_nIndex);
            InsertString(m_nIndex, m_strItemText);
            SetItemData(m_nIndex, dwData);
But now in DeleteString the dwData will be destroy.
But SetItemData put the deleted Item pointer into the List.

Any solution to solve this problem ?

Hi,

I think you need move this code from DELETEITEM_REFLECT to some OnDestroy.

Same DeleteString/InsertString used a lot in code - in OnMoveItemUp/OnMoveItemDown/OnItemBrowse etc.

Is it not easyer to swap item text and item data, instead of delete insert ?

Hi,

It sounds weird, but in Windows API there is no way to set text for existed listbox item.

btw, check CustomizeDlg sample. It used

ON_LBN_XT_PREDELETEITEM(IDC_LBOX_TOOLSLIST, OnPreDeleteItem)

to delete items.
