DELETEITEMSTRUCT info  Overview  Group

The DELETEITEMSTRUCT structure describes a deleted list box or combo box item. The lParam parameter of a WM_DELETEITEM message contains a pointer to this structure. When an item is removed from a list box or combo box or when a list box or combo box is destroyed, Windows sends the WM_DELETEITEM message to the owner for each deleted item.

Windows NT: Windows sends a WM_DELETEITEM message only for items deleted from an owner-drawn list box (with the LBS_OWNERDRAWFIXED or LBS_OWNERDRAWVARIABLE style) or owner-drawn combo box (with the CBS_OWNERDRAWFIXED or CBS_OWNERDRAWVARIABLE style).

Windows 95: Windows sends the WM_DELETEITEM message for any deleted list box or combo box item with nonzero item data.
