Using a push button for a user input path which can be used to open and read .hxml files

my code:

function pushbutton1_Callback(hObject, eventdata, handles)

[file,path] = uigetfile('*.hxml');

if ischar(FileName)

%disp('file selected')

eval(['!notepad++ ' PathName FileName])

else

disp(['User selected ', fullfile(path,file)]);

end

I understand from your query that you are trying to open HXML file using callback to a push button.

Below is the code snippet for the callback function to push button.

function ButtonToReadHXMLPushed(app, event)

[file,path] = uigetfile('*.hxml');

if isequal(file,0)

disp('User selected Cancel');

else

disp(['User selected ', fullfile(path,file)]);

system(['notepad ' fullfile(path,file)]);

end

end

Here, replacing “eval” function with “system” function gives the desired outcome. This solution uses notepad to display the contents of HXML file. If the contents are required to be displayed in notepad++, just replace “notepad” with “notepad++” in system call.

This solution has been tested on MATLAB R2023b. For more information about user input from file picker please refer to this documentation: https://www.mathworks.com/help/matlab/ref/uigetfile.html?s_tid=srchtitle_support_results_1_uigetfile#d126e1714445 .

For more information about the "system” function, please refer this documentation: https://www.mathworks.com/help/matlab/ref/system.html?s_tid=doc_ta#:~:text=Product%20Updates-,system,-Execute%20operating%20system .

Hope this helps!
