Same script - 2 pcs - error on one PC only with setappdata

Hi, I made a gui which shares data via setappdata/getappdata. Everything works like charm, but when I send it to my friend (m-files), it always says invalid handle object in one of the setappdata lines. I store data in root and in main gui and I call it via main handles stored in root.

Only he has the error message, could it be because he has 64-bit version ( I have 32)? Or the root itself is a problem?

I havent find any answers so far.

Edit: To be completely clear, it worked for him few days ago even when he wrote some application with it. Now every setappdata gets him invalid object handle, even in a script that he used and worked( wasnt changed btw) Thanks!

Please post the failing code. Otherwise an answer is guessing only.

ok, so in the main gui in opening function I defined:

function gui_OpeningFcn(hObject, eventdata, handles, varargin)

handles.output = hObject;

guidata(hObject, handles);

setappdata(0 , 'hMainGui' , gcf);

setappdata(gcf,'updateData', @updateData);

Then in the import gui, whick I open through main gui, I have on Ok press:

function push_ok_Callback(hObject, eventdata, handles)

hMainGui = getappdata(0, 'hMainGui');

setappdata(hMainGui,'impData',get(handles.table_import,'data'));

setappdata(hMainGui,'impName',get(handles.editName,'String'));

updateData = getappdata(hMainGui,'updateData');

feval(updateData);

gui_import('push_cancel_Callback',hObject,eventdata,guidata(hObject))

A while back without changing a thing it wrote him an error with feval.

It didn't read the updateData from getappdata :/

This is the error for him, even thou it still works for me.

setappdata saves the data in a user file. Perhaps removing that file (might want to rename it) would help.

[Charles]

You mean like another file in the folder with the script? Nothing was created and if u meant the file itself it didn't work.

[Jan]

SETAPPDATA does not write to a file.

[Walter Roberson]

Ah yes, Jan is correct. I was thinking of setpref()
