I can't get GUI text entry

hello

_ knowing that many people posted the same problem but no working solution has been proposed._

I got this error "Attempt to reference field of non-structure array" when I try get the input from GUI.

I made a simple GUI (edit1 and pushbutton1) in order to see if the problem is from my first GUI then I make necessary corrections.

Unfortunately, I got the same error.

Here is the code of the simple GUI. I didn't change anything in what GUIDE generated except deleting unnecessary comments.

Any thoughts about this.

function varargout = untitled(varargin)
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                   'gui_Singleton',  gui_Singleton, ...
                   'gui_OpeningFcn', @untitled_OpeningFcn, ...
                   'gui_OutputFcn',  @untitled_OutputFcn, ...
                   'gui_LayoutFcn',  [] , ...
                   'gui_Callback',   []);
if nargin && ischar(varargin{1})
    gui_State.gui_Callback = str2func(varargin{1});
end

if nargout
    [varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});
else
    gui_mainfcn(gui_State, varargin{:});
end

end

when i run this code, it throws error stating, no gui present. mail me the code and gui to [e-mail]

I want add something here. When I debugged the code, I noticed that handles is empty. The line where the error is fired is this one

W(1).name = get(handles.edit1,'string');

It looks okay. The only thing I think might possibly be wrong is the (1). Try using W.name instead of W(1).name and see if that works. If not, attach both the fig file and m file with the paper clip icon.

By the way, with just that code you've shown, you won't be able to access W once that callback exits.

It didn't work neither.

Actually, in my original GUI, I have multiple entries that I want put them in a struct-array, that's why I put that W(1).

what do you mean by "with just that code you've shown, you won't be able to access W once that callback exits" ? what should I do more ?

So you just put it into W but never do anything with it afterwards. Do you ever want to use it again? If so, see the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

of course I'm going use it for something else.

Let me tell you WOW for the set of tutorials
