Hi Peppe, well.. you kind of answered most of it ;)
So If you have uploaded the code I will hopefully find some time to check in the next days. As far as I recall, getting the original data is fairly easy (just using some other function that returns the same data-type) - but well, I programmed it 2 years ago and therefore need to look at it again too. saludos, stefan Am 17.07.13 16:07, schrieb Giuseppe Aruta: > Hi Stefan, > many questions.
