In GUI when i click on some button, then text file which is already exist in directory should open. I searched in matlab help, but i can find only about to create and save text file only. There is no any command which pop up saved text file.!

Nimisha - what do you mean by popup saved text file? Do you want to open the MATLAB editor so that you can view the file, or some other editor, or ..?

If you just want to open the text file in the editor of your choice, then you can try using the system function. For example, if I wish to open a text file using TextEdit (on a Mac), I could execute the following statement in the MATLAB Command Window

 system(['open -a TextEdit ' fullfile(pwd,'myOutput.txt')])

Note that I use fullfile to build the full path to the text file named myOutput.txt. The complete string that I pass to system is

 ['open -a TextEdit ' fullfile(pwd,'myOutput.txt')]

 ans =
    open -a TextEdit /Users/geoff/matlab/testing2/myOutput.txt

Try the above and see what happens!

I RUN it. It just prints

 open -a TextEdit C:\Users\admin\Desktop\Passport.txt

in command window. And something same goes in workspace.

But No Text file is opened. I should be able to see text file content which is written inside it.

Nimisha - it was an example that works on my Mac because I have the TextEdit application that can be used to read text files. Given your folder of C:\Users\..., you must be using Windows and so probably don't have TextEdit. You will have to replace this with notepad.exe or something similar.

For example,

 system('notepad C:\Users\admin\Desktop\Passport.txt');

See previous comment. Perhaps

system('notepad C:\Users\admin\Desktop\Passport.txt');

will work for you on Windows.
