How to dynamically load struct-data into listbox

Hey Guys, i have a struct called DBC. I want to read the following data from this struct into a listbox in a guide GUI. DBC.Message(1).MessageName and DBC.Message(2).MessageName

In my gui, i open a text file and then with a help of another .m-file I read its data into my Struct 'DBC'.

I have problems to visualise data of the struct in a listbox. Here is the code:

if true
function OpenDBC_Button_Callback(hObject, eventdata, handles)
[filename,path,cancel_check] = uigetfile('*.dbc',...
                                  'Choose DBC-File',...
                                  'Multiselect','off');
assignin('base','filename',filename);                     
assignin('base','path',path);
assignin('base','cancel_check',cancel_check);
DBC_read_test %another m-file, which reads the file and saves its data into a struct 'DBC'
assignin('base','DBC', DBC);
msgs=0;
for msgs = 1:size(DBC.Message) %iterate through the struct
  set(handles.MessageList,'Value',msgs);
  set(handles.MessageList,'String',DBC.Message(msgs).MessageName); 
end

end

My problem is that in the GUI only one entry is displayed, although there are several entries in the struct. Help anyone? THANKS!

The term "path" is an important Matlab command. Shadowing it by a variable is a bad idea.
