GUI report error if something is wrong
显示 更早的评论
I have a GUI that has a static text box which I use to update for the status of the code. The GUI needs to load data from an excel file (xlsread), and sometimes the load fails due to mistakes in the data file. I want to have a string saying "Error loading data!" to appear if the xlsread function fails. Is there a good way to do it. Thanks

You could use try/catch statements where you use the xlsread function. Edit the code in your callback function like this:
try
NumData = xlsread(FileName); %wrap your xlsread with try/catch statement
catch
set(handles.text1, 'String', 'Error loading data!'); %update your status text
drawnow; %redraw GUI to ensure the new string shows
return %end the callback function prematurely due to error
end
