CB_GETITEMDATA message

An application sends a CB_GETITEMDATA message to a combo box to retrieve the application-supplied value associated with the specified item in the combo box.

Parameters

wParam

The zero-based index of the item.

lParam

This parameter is not used.

Return value

The return value is the value associated with the item. If an error occurs, it is CB_ERR.

If the item is in an owner-drawn combo box created without the CBS_HASSTRINGS style, the return value is the value contained in the lParam parameter of the CB_ADDSTRING or CB_INSERTSTRING message, that added the item to the combo box. If the CBS_HASSTRINGS style was not used, the return value is the lParam parameter contained in a CB_SETITEMDATA message.
