Hi again, ne wday new problem.
I have a GUI that takes the attributes for a student, name, address etc and
stores it to a random file. I everything works fine, but now I have to be able
to update the information in the file. When I veiw the student information in
the studentpanel, I should be able to edit the textfields and click on an update
button that will update the file. I don`t want to append on to the existing
file, I just want to overwrite it with the new information...at least thats what
I think it should be doing.
I created my update button and Now I am in the
process of figuring out the actionevent for it,,,,except I do not have a clue, I
havn`t even been able to find any basic examples of this.
This is what I
have so far.
