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.

Syntax 

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 lpszparameter is stored as item data instead of the string it would otherwise point to. You can send the LB_GETITEMDATAand LB_SETITEMDATAmessages to retrieve or modify the item data.

Return Value

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.

Requirements

Header winuser.h
Windows Embedded CE Windows CE 1.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
