An application sends a CB_ADDSTRING message 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.

CB_ADDSTRING
wParam = 0; // not used; must be zero
lParam = (LPARAM) (LPCTSTR) lpsz; // address of string to add

Parameters

lpsz

Value of lParam. Points 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 Values

The return value is the zero-based index to the string in the list box of the combo box. If an error occurs, the return value is CB_ERR. If insufficient space is available to store the new string, it is CB_ERRSPACE.

Remarks

If you create an owner-drawn combo box with the CBS_SORT style but without the CBS_HASSTRINGS style, the WM_COMPAREITEM message is sent one or more times to the owner of the combo box so the new item can be properly placed in the list.
To insert a string at a specific location within the list, use the CB_INSERTSTRING message.

See also CB_DIR, CB_INSERTSTRING, WM_COMPAREITEM
