LB_ADDSTRING

  • Article

This message is sent by an application to add a string to a list box. If the list box does not have the LBS_SORT style, the string is added to the end of the list. Otherwise, the string is inserted into the list and the list is sorted.

LB_ADDSTRING wParam = 0; 
  lParam = (LPARAM)(LPCTSTR) lpsz;

Parameters

  • wParam
    Not used.

  • lpsz
    Long pointer to the null-terminated string to be added.

    If you create the list box with an owner-drawn style, but without the LBS_HASSTRINGS style, the value of the lpsz parameter is stored as item data instead of the string it would otherwise point to. You can send the LB_GETITEMDATA and LB_SETITEMDATA messages to retrieve or modify the item data.

Return Values

The zero-based index of the string in the list box indicates success. LB_ERR indicates that an error has occurred. LB_ERRSPACE indicates that there is insufficient space to store the new string.

Remarks

Windows CE does not support owner draw list boxes.

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Winuser.h.
