LB_GETITEMDATA

  • 项目

This message is sent by an application to retrieve the application-defined 32-bit value associated with the specified list box item.

LB_GETITEMDATA wParam = (WPARAM) index; 
  lParam = 0;

Parameters

  • index
    Index of the item.

Return Values

The return value is the 32-bit value associated with the item, or LB_ERR if an error occurs. If the item is in an owner-drawn list box and was created without the LBS_HASSTRINGS style, this 32-bit value was in the lParam parameter of the LB_ADDSTRING or LB_INSERTSTRING message that added the item to the list box. Otherwise, it is the value in the lParam of an LB_SETITEMDATA message.

Remarks

Windows CE does not support owner draw list boxes.

Requirements

Header: Winuser.h.
