Hi everyone,
I have come up with a very strange problem. I had a GUI+the code to communicate to a serial device and plotting the data on screen. Every thing was perfectly working till yesterday, today when I resumed my work, my GUI buttons,text inputs etc nothing work, I checked the search path if my directory is missing from the search path but everything seem to be okay.
In order to verify that the problem is not with my GUI and code, I created completely new test GUI with a single button in it such that when the button is pressed (callback function) it should display a message box i.e.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
%%set(handles.pushbutton1,'String','Connect');
msgbox('Hello World');
but the GUI is not responding to its corresponding code. It looks like there is a permanent break between the GUI interface and my code.
Any idea ?

Can you attach the new GUI's .m and .fig files (the simple one you created to test).

Well somehow your original source code got overwritten. Take it from your back up, so maybe you'll only lose a few hours or a day of work, depending on how long ago you did your last backup. If, for some inexcusable reason, you don't have a backup, see if you can rename your m-file, or delete it if it's totally bad, and rename the .asv file to .m. The .asv file is the last version of your file and as long as you didn't save this corrupted version, it might be okay - it might possibly (if you're lucky) be your original file.

Hi,
Thank you for your valuable answer. As I mentioned the problem is not in the code because I created completely new project in another directory. The GUI contains a single button with a callback function i.e.
unction pushbutton1_Callback(hObject, eventdata, handles) % hObject handle to pushbutton1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) %%set(handles.pushbutton1,'String','Connect'); msgbox('Hello World');
Still this new project is not working. The matlab console dosent give any error or warning message.
Any idea ?

I seem to recall the same problem I've encountered, it had to do with different (I update) file name between the GUI file (.fig) with the mfile (.m). I was updating calculation on the mfile and for version management I 'cleverly' changed the filename and delete the obsolete version :(.
Could this be your problem, i.e. different filename?
