Hi All,
Before I go ahead and code some binary version of my XML-based
document file I'd just like to ask if there's a right and wrong way
to save and read a binary file for this purpose having never really
used binary files before.
Background:
Basically my app currently reads and writes all of its data in xml
format. It is for the main purely text but also contains images
which are stored in the xml as file references by EncodeBase64. (I
initially stored the pictures to the xml file with Norman's
pictureToString routine but a saved file would grow so large that it
wasn't practical.)
But now I need to add more images to the file and (more importantly)
make the file portable, in which case file references just won't do
and so I'm f going down the binary file route.
So my question is - what's the best approach to storing different
kinds of text and images in one binary file for use as a document
file by my app? Any pitfalls/ schoolboy errors to watch out for?
The first error would be to fail to include file format version
information.
