checking file corruption

[David Winters Junior]

Hi All,

I am currently looking at means to test whether the file and its contents are not corrupt?

I am currently checking the size of each record size returned when i read the byte data from the database and ensuring it is the correct size.

What have others checked here?

Thanks,
david

I don't mean to hijack this thread, but I would like to add on to the question by asking if file corruption checking is something that should be included and within the scope of the assignment.

Hi,

Well yes of course, if the data in the file is in anyway bad or the wrong data is contained in the .db file then the whole application will fail so yes it should be verified and checked in some way.

Thanks,

I only read the magic cookie before opening the file to find out the file is correct or not.

Checking the file corruption is beyond the scope (if your instruction didn't require you to do so) and I think you'll not get an extra point if you do the things that didn't required by the instruction.

Good luck
