revise this code

PLEASE compile this code on your pc and add some new items then try to
update it using update button and we will see mu problem clearly which
is:
I have a main window ,by clicking on (add new item) , another window
open to fill the form
on clicking on (save to file),my form will be saved in text file.
if I open this text file using notepad for example,then I found my data
stored but concatenated
although I add to the saved string "\n" [hint:you will find two ## to
direct u to this line in
                                                    my code text]
if I change it to "\n\n" then my data is stored in separate lines which
I need.
the Problem that when I read the saved file by clicking on "update data
item" ,the returned
data in the form is not as saved
