Hi everyone, I have a problem with trying to populate the listbox in a GUI. I want to click a pushbutton 'browse', select any folder on my computer and have the GUI load all the files in that folder to a listbox (listbox1) so the user can see all the files in that folder. I asked this in an earlier question but cannot comment on the answer so started a new question. So far, thanks to Orion, I have this code under the pushbutton callback function:

% 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)

When I ran the GUI, I clicked browse, chose a folder and I received this error:

Struct contents reference from a non-struct array object.

Error in GUI_2>pushbutton1_Callback (line 120) set(handles.listbox1,'String',MyListOfFiles)

Error in gui_mainfcn (line 95) feval(varargin{:});

Error in GUI_2 (line 42) gui_mainfcn(gui_State, varargin{:});

Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)GUI_2('pushbutton1_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback

Any ideas? I feel like I should have some code under the listbox createfcn and listbox callback functions too?

Cheers, Ellis

PS: If you had stuck with your original question you would have learned that you can replace most of your code (the loops) with these two lines:

S = dir(folder_name);
N = {S(~[S.isdir]).name}

This is what happens when people ask the same question in multiple locations: they lose track of what info that have been given.
