Hello,
In my application I have to make automatic printouts of receipts.
It should normally not be possible for the user, to print one receipt manually twice, because it is a document. But what, if the printer strikes? So I would like to append the report info into a simple text file that the document-info is not lost, which should not be a problem. But I don't want to get this file too big. Say, after a while, the oldest entries should be deleted automatically, when a certain size of the file is reached.
How can I do this?
Thanks in advance.
