combo boxes

after I inited a combo box.... how can i make a string to be shown at the top of the combo box, next to the "down arrow" of the combo box.

thanks.

Code:

...
SendMessage (hWndCombo,
             CB_ADDSTRING,
             0,
             (LPARAM)(LPSTR) strSingleEditLine);
...
SendMessage (hWndCombo,
             CB_SETCURSEL,
             (WPARAM) index,
             0);
