hey!!

i am trying to call one gui from another gui using this code for the push buttons suppose from GUI_1 i have to call GUI_2

     pushbutton1_Callback(GUI_2);
     GUI_2.m;
     errordlg('Ok the call back is linked');

its working for one of the gui's but not for the other. this is the error which m getting

                                                                                 *Error in sample>pushbutton2_Callback (line 94)
    pushbutton2_Callback(start_gui_single_mode);
    Error in gui_mainfcn (line 96)
        feval(varargin{:});
    Error in sample (line 42)
    gui_mainfcn(gui_State, varargin{:});
    Error in                                                                              @(hObject,eventdata)sample('pushbutton2_Callback',hObject,eventdata,guidata(hObject))
    Error while evaluating uicontrol Callback*

This is the part of the error message, which explaines where the problem occurred. But the part is missing, which tells what the error is.

The reference to page, which contains about 24 links, is not helpful. Of course the readers of this forum will not read all of them to find out more.

在 MATLAB Online 中打开

You call a function by using its name without file extension:

GUI_2; % Instead of: GUI_2.m;

I'm not sure if this causes your problem, but it is at least not correct.

m sorry for the inconvenience

the code is:

//
gui_Singleton = 1;
gui_State = struct('gui_Name',       mfilename, ...
                 'gui_Singleton',  gui_Singleton, ...
                 'gui_OpeningFcn', @sample_OpeningFcn, ...
                 'gui_OutputFcn',  @sample_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{:}); /////line no 42
end
% End initialization code - DO NOT EDIT
     function sample_OpeningFcn(hObject, eventdata, handles, varargin)
    % This function has no output args, see OutputFcn.
   % hObject    handle to figure
  % eventdata  reserved - to be defined in a future version of MATLAB
  % handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to sample (see VARARGIN)
% Choose default command line output for sample
 handles.output = hObject;
   % Update handles structure
    guidata(hObject, handles);
% UIWAIT makes sample wait for user response (see UIRESUME)
% uiwait(handles.figure1);
% --- Outputs from this function are returned to the command line.
function varargout = sample_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% Get default command line output from handles structure
varargout{1} = handles.output;
% --- Executes on button press in pushbutton2.
function pushbutton2_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton2 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
pushbutton2_Callback(start_gui_single_mode); ////line no 94
   start_gui_single_mode;
   errordlg('Ok the call back is linked');////line no 96
//

and the here the fingerprint recognition code (in the code start_gui_single_mode) is available on this site:

http://www.comp.hkbu.edu.hk/~vincent/resPaper.htm

and on this page the source code is available at the end of the page. u can download .m files from there if u want.

thank you for replying!!
