MATLAB: Displaying contents in a list bx after button press

guiMySQL

Hi I have a GUI, in which i press a button and it obtains all he file names from my database. I then want this to be displayed within a list box but can't get the list box to update can someone help please?
here is my code so far:
% --- Executes on button press in pushbutton7.
function pushbutton7_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton7 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB

% handles    structure with handles and user data (see GUIDATA)
global str;
str = getfilenames;
disp(str);
% --- Executes during object creation, after setting all properties.
function listbox1_CreateFcn(hObject, eventdata, handles)
% hObject    handle to listbox1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    empty - handles not created until after all CreateFcns called
% Hint: listbox controls usually have a white background on Windows.
%       See ISPC and COMPUTER.
if ispc && isequal(get(hObject,'BackgroundColor'), 
get(0,'defaultUicontrolBackgroundColor'))
set(hObject,'BackgroundColor','white');
end
 global str;
 set(hObject, 'String', str2 );

Your code is not clear for me, but I see that you are creating a list in the listbox callback while you should do it in the push button callback
