DELETEITEMSTRUCT

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, the system sends the WM_DELETEITEM message to the owner for each deleted item.

Windows NT: The system 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 and Windows 98: The system sends the WM_DELETEITEM message for any deleted list box or combo box item with nonzero item data.

typedef struct tagDELETEITEMSTRUCT { // ditms 
    UINT CtlType; 
    UINT CtlID; 
    UINT itemID; 
    HWND hwndItem; 
    UINT itemData; 
} DELETEITEMSTRUCT;
