yes of course

function MBA_MainForm_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 MBA_MainForm (see VARARGIN)
if(isempty(varargin))
    handles.MainCtrl = CMBAMainCtrl();
else
    handles.MainCtrl = varargin{1};
end
% Choose default command line output for MBA_MainForm
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
% UIWAIT makes MBA_MainForm wait for user response (see UIRESUME)
% uiwait(handles.figure1);
list = handles.MainCtrl.GetProjectList();
if(~isempty(list))
    set(handles.PrList, 'String', list);
end
prj = handles.MainCtrl.LastProject;
if(~isempty(prj))
    if(isempty(varargin))
        close;
        MBA_ModuleForm(handles.MainCtrl);  // the error is on this line
    else
        set(handles.CfgName, 'String', prj.CfgName); 
        set(handles.WdPath, 'String', prj.FolderName,'HorizontalAlignment','left'); 
        [a,b,c]=fileparts(prj.SwarFile);
        set(handles.SwarFile, 'String', [b,c],'HorizontalAlignment','left'); 
        [a,b,c]=fileparts(prj.YedarFile);
        set(handles.YedarFile, 'String', [b,c],'HorizontalAlignment','left');

Please, post the full text of the error message. Everything in red. In particular, we need to see the bit that tells us which line is actually throwing the error.

stephane teiguim 2020-1-21

the full error is :

Error: Functions cannot be indexed using {} or . indexing.

Error in MBA_MainForm>MBA_MainForm_OpeningFcn (line 106)

MBA_ModuleForm(handles.MainCtrl);

Error in gui_mainfcn (line 220)

feval(gui_State.gui_OpeningFcn, gui_hFigure, [], guidata(gui_hFigure), varargin{:});

Error in MBA_MainForm (line 71)

gui_mainfcn(gui_State, varargin{:});

Thanks. This is puzzling since the line that is causing the error cannot actually throw that error. I suspect that the error is actually inside the MBA_ModuleForm function which for some reason makes a call throwAsCaller so that the error appears on the calling line.

Can you share the code for MBA_ModuleForm?

stephane teiguim 2020-1-21

Yes the error came from MBA_ModuleForm , on my first comment i posted a part of a code of MBA_ModuleForm be cause the script is too long, it take 639 line.

Do you always want that i share it there?

Guillaume 2020-1-21

You've posted part of MBA_MainForm, but the error appears to come from MBA_ModuleForm.

But yes, it would be useful to have the full code. Attach the m file to the question.
