how can I save the value of a text area from app designer into a file .txt?

I have to save the content of a text area into a specific folder as a file .txt.

I am able to do it in matlab but I can manage to pass the function in app designer.

this is the function I used in matlab for a similar issue (to pass a vector into a file.txt) :

function write_txt_file(vector,filename,directory)

%
%Function that writes a vector with NUMERICAL DATA to a file with a certain
%filename in a certain directory
%
% vector: vector/matrix variable containing the data to be written
% filename: name of file to be saved, i.e., [imagename '-LI.txt']
% directory: directory where the file should be saved

[r, c]=size(vector);

if ~isfolder(directory)
    mkdir(directory)
end

if directory(end) == '/'
    directory = directory(1:end-1);
end

if strcmp(filename(end-3:end),'.txt')
    fp=fopen([directory '/' filename],'w'); 
else
    fp=fopen([directory '/' filename '.txt'],'w');
end

if ~isempty(vector)
    for i=1:r
       for j=1:c
           fprintf(fp,'%f ',vector(i,j));
       end
       fprintf(fp,'\r\n');
    end
end

fclose(fp);
end

Attached is a sample app designer file.

If button is pressed, a number written in text area will be save as a text file.

% Button pushed function: SaveButton
function SaveButtonPushed(app, event)
    vec = str2double(app.TextArea.Value{:});
    write_txt_file(vec, 'test', '.');
end

You can access to the characters by app.TextArea.Value and, in order to fit them to your write_text_file function, I've converted characters to double.

Hi Kojiro,

Thanks for answering this question where where does write_txt_file come from? I can't seem to get the attached file to run.

Thanks,

Jeff

Hi Jeffrey,

write_txt_file was a funciton that the questioner (Gabriele Penna) wrote in the above question.
