CB_ADDSTRING

A version of this page is also available for

Windows Embedded CE 6.0 R3

4/8/2010

This message is sent by an application to add a string to the list box of a combo box. If the combo box does not have the CBS_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

CB_ADDSTRING wParam = 0; 
    lParam = (LPARAM)(LPCSTR) lpsz;

Parameters

• wParam
  Not used.

• lpsz
  Long pointer to the null-terminated string to be added. If you create the combo box with an owner-drawn style but without the CBS_HASSTRINGS style, the value of the lpsz parameter is stored as item data rather than the string it would otherwise point to. The item data can be retrieved or modified by sending the CB_GETITEMDATA or CB_SETITEMDATA message.

Return Value

The zero-based index to the string in the list box of the combo box indicates success. CB_ERR indicates that an error has occurred. CB_ERRSPACE indicates that insufficient space is available to store the new string.

Remarks

To insert a string at a specific location within the list, use the CB_INSERTSTRING message.
