Hi Ellis,
let say you have one pushbutton and one listbox (tagged pushbutton1 and listbox1 with GUIDE).
in the callback of your pushbutton, you should do something like :
function pushbutton1_Callback(hObject, eventdata, handles)
% get the folder
folder_name = uigetdir;
% get what is inside the folder
Infolder = dir(folder_name);
% Initialize the cell of string that will be update in the list box
MyListOfFiles = [];
% Loop on every element in the folder and update the list
for i = 1:length(Infolder)
if Infolder(i).isdir==0
MyListOfFiles{end+1,1} = Infolder(i).name;
end
end
% update the listbox with the result
set(handles.listbox1,'String',MyListOfFiles)
That should do it
