How to make a resetable input box?

[Lauri R.]

I'm programming an education application, which poses a problem to a
student and then takes the student's input. After that it checks
whether the answer was correct or incorrect and prints the outcome.

I'd like to make the input field by simply using an input_box of the
interact feature, but my problem is that after each question it should
reset all the fields and introduce a new question. However, as far as
I know, it is impossible to reset the values of interactive fields or
alter them in any way.

Am I right or is there a way to do this? Are there any other
solutions? If someone has experience in making this kind of programs,
I'd like to hear what technologies you have used.

Thanks in advance!

- Lauri R.

PS. Is it possible to hide source code in a notebook in the same way
one can hide an output?

I don't know. However, I would try something like Marshall Hampton's
http://wiki.sagemath.org/interact/diffeq#Euler.27sMethod.2CImprovedEuler.2Cand4thorderRunge-Kuttainonevariable
but with "input_box(' ' " or "input_box(default=' ' " in place of the
default value
he has there.

Use %hide as the top line

I was working on an interactive debugger for the notebook (using
interact), and ran into the same problem. I'll try to think of a way
to fix this problem by improving interact this week.
