Hi
I have been using the following link to inspect the contents of the db file :-
http://www.fileformat.info/tool/hexdump.htm
However, it does not allow the bytes in the file to be modifed. I just wondered if anyone can point me to something similar but allows specific bytes to be modified.
Regards
Pete

Pete - try this, I used this one for myself. It allows editing.

Download version 2.5 (Free).

Why would you want to edit the content of the db-file? why not use your Data-class ? or write a small program with a RAF or a FOS to manipulate it.

Alain,
Thanks for the suggestion seems to work nicely.
Roel,
The db file provided to me has all the 2 byte record flag set to VALID (00 00) and after some testing I have some set to DELETED (0x8000), however, I wanted to ensure that I handled records with the record flag set to something "invalid". Using the hex editor, I am able to modify flags accordingly and run further tests to confirm this.
Regards
Pete
