matlab gui to exe error(i cannot load excel file)

i can not load excel file in exe file only

in matlab gui it works properly

here is my code.

%
[fileName,pathName]=uigetfile('*.xls','Select your file'); %온도 레코더
 handles.fileName=[fileName,pathName];
 [~,txt,~]=xlsread(fileName,'C27:C30000');   
 [Ch1,~,~]=xlsread(fileName,'E27:E30000');
%

uigetfile() does not promise that pathName will end in a directory separator. You should use fullfile(pathName, fileName)

... And you also reversed the order when you constructed the file name. You put the filename and then the directory.

it still doesn't work ...i don't know what's wrong

i think xlsread function doesn't work in exe

[Walter Roberson]

[fileName, pathName] = uigetfile('*.xls','Select your file'); %온도 레코더
if ~ischar(fileName)
    error('User cancel file selection');
end
handles.fileName = fullfile(pathName, fileName);
 [~,txt,~] = xlsread(handles.fileName, 'C27:C30000');   
 [Ch1,~,~] = xlsread(handles.fileName, 'E27:E30000');
