An application sends an LB_GETTEXT message to retrieve a string from a list box.
LB_GETTEXT wParam = (WPARAM) index; // item index lParam = (LPARAM) (LPCTSTR) lpszBuffer; // address of buffer
Windows 95: The wParam parameter is limited to 16-bit values.
This means list boxes cannot contain more than 32,767 items. Although the
number of items is restricted, the total size in bytes of the items in a
listbox is limited only by available memory.
The return value is the length of the string, in characters, excluding the terminating null character. If index does not specify a valid index, the return value is LB_ERR.
If you create the list box with an owner-drawn style but without the LBS_HASSTRINGS style, the buffer pointed to by the lpszBuffer parameter will receive the 32-bit value associated with the item (the item data).
