My saving function works before compiling it as a standalone software using app designer

The save function works and save the data from the table to .mat folder when i run in matlab. But after i compile it into a standalone software, it does not work the same way. It does not save no more and when i press the save button, it acts as error.

function startupFcn(app)
app.anam=load("Anam.mat","mergefilesanam");
assignin("base",'anam',app.anam);             
app.data=evalin("base",'anam.mergefilesanam');
app.UITable_2.Data=app.data;
app.UITable.Data=app.data;
app.UITable_2.ColumnName=app.data.Properties.VariableNames;
app.UITable.ColumnName=app.data.Properties.VariableNames;
app.numRows=size(app.data,1);
end

function savebuttonImageClicked(app, event)
mergefilesanam=(app.UITable.Data);
save("Anam.mat","mergefilesanam");
anam=load("Anam.mat","mergefilesanam");
assignin("base",'anam',anam);
end

Specify the full file name -- folder plus base file name plus extension:

folder = 'd:\mydata'; % Wherever you want.
fullFileName = fullfile(folder, 'Anam.mat');
save(fullFileName,"mergefilesanam");

and if i want to call the file back and display it in the table should is use load(fullfilename)?

[Walter Roberson]

aman = load(fullFileName);
assignin("base", 'anam', anam);

Remember though that that will be a struct with one field for every variable that was saved in the file.

You should probably not be working with the base workspace in App Designer. Create an app property instead.

[Aung Moe Zaw]

should be like this?

app.aman = load(fullFileName);

assignin("base", 'anam', app.anam);

[Aung Moe Zaw]

property(Access=Public)

anam;

end

function startupFcn(app)

folder = 'C:\Program Files\Citanix\machineinterface'; % Wherever you want.

fullFileName = fullfile(folder, 'Anam.mat');

app.anam=load(fullFileName,"mergefilesanam");

assignin("base",'anam',app.anam);

app.data=evalin("base",'anam.mergefilesanam');

app.UITable.Data=app.data;

app.UITable.ColumnName=app.data.Properties.VariableNames;

end

function savebuttonImageClicked(app, event)

folder = 'C:\Program Files\Citanix\machineinterface'; % Wherever you want.

fullFileName = fullfile(folder, 'Anam.mat');

mergefilesanam=(app.UITable.Data);

save(fullFileName,"mergefilesanam");

app.anam=load(fullFileName,"mergefilesanam");

assignin("base",'anam',app.anam);

end

should i try like this?

Did your app cd() to somewhere? If not, then what directory do you think you are in at the time you save() ?

I am not sure about that....all the files that i use are in the same folder when i call/load and save when using matlab...do you have a sample coding i could refer to?
