uigetfile only let me choose file from the current folder.how can i choose from anywhere?

these is my code:

% --- Executes on button press in ImSelect.
function ImSelect_Callback(hObject, eventdata, handles)
% hObject    handle to ImSelect (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% global pathname;
% global filename;
[filename,pathname] = uigetfile('*.jpg');
f=open(fullfile(pathname,filename) );
selected=sprintf('%s',filename);
i=imread(selected); %reading your .jpg image
axis(handles.axes1); %setting the image in axes1 component -look at thag property of axes which is default axes1
imshow(i)
handles.pathname = pathname;
handles.filename = filename;
guidata( hObject, handles )

when I try to choose a jpg from any other folder than the current one, it makes a mistake sound and nothing opens..how to repait this?

 selected=sprintf('%s',filename);

should be

 selected=sprintf('%s',fullfile(pathname,filename));

yeah it works, but now each time I choose a file it shows me that window:

how can i cancel it?

[Iain]

I'm pretty certain you don't need "f=open(fullfile(pathname,filename) ); ", which pops that window up.

yep,now it works! thanks alot Iain!!
