How to cancel the save program?

22 views (last 30 days)
Hye guyz. I need some help here. I have this coding:
fileName = inputdlg('Please enter the name for your figures');
directoryName = uigetdir('','Please select a folder to save to');
if directoryName == 0 %# User pressed the "Cancel" button...
directoryName = ''; %# ...so choose the empty string for the folder
end
filePath = fullfile(directoryName,fileName{1}); %# Create the file path
extensions = {'fig','bmp'};
for k = 1:length(extensions)
saveas(gcf,filePath,extensions{k}); %# Save the file
set(gcf,'PaperPositionMode','auto');
end
This coding have some problem. When i run this coding, it occurs this error:
??? Index exceeds matrix dimensions.
Error in ==> fyp_editor>uipushtool9_ClickedCallback at 1607 filePath = fullfile(directoryName,fileName{1}); %# Create the file path.
And another thing is when i pressed the cancel button, it kkeep going to filepath. How i want to do something like; when i push the cancel, then it will cancel the save program.

Another way, might be better because the return function can have undesirable consequences.
fileName = inputdlg('Please enter the name for your figures');
directoryName = uigetdir('','Please select a folder to save to');
if directoryName == 0 %# User pressed the "Cancel" button...
directoryName = ''; %# ...so choose the empty string for the folder
else
filePath = fullfile(directoryName,fileName{1}); %# Create the file path
extensions = {'fig','bmp'};
for k = 1:length(extensions)
saveas(gcf,filePath,extensions{k}); %# Save the file
set(gcf,'PaperPositionMode','auto');
end
end

i think i already solve it by writing this code:
if isempty(fileName)
return
end
Thanks in advance

You should be checking that fileName is not empty, which would happen if the user does not enter anything in response to the inputdlg or cancels it.
