Graham:
I'm not sure I understand your question so let me try an answer
and you can tell us whether that answer is germane to your
question ;-).
Essentially, there are two ways to store any non-textual
data in association with a basically-textual document:
o Internally - In this situation, you store the actual
non-textual data within the text document. This almost
always requires recoding it into a textual format that
will fit within your text document. Base64 encoding is
one very common method of doing this. The upside is
that everything you (or your users) need is in one file;
nothing gets lost or left behind if the file is transferred.
The downsides are that 1) the file can grow large; 2) the
file contains long runs of date that's not-very-readable
by humans; and 3) the user will need your tool to extract
the embedded images (etc.).
o Externally - In this situation, you keep the non-textual
files in whatever native format they arrived in and just
embed a link to them within your textual document.
The advantages and disadvantages are the reverse of
the situation above. Advantages: 1) The textual file
stays at an easily-manageable size; 2) The textual file
remains entirely readable by humans; and 3) the user
doesn't need any special tools to access the images (etc.).
The disadvantage is that it's very easy to leave an image
(or what-have-you) behind, especially if it's located in
a far-off folder. In this situation, the receiving user won't
have a complete document.

Hi
I am attempting to develop a simple text editor app that is able to save and
read files in a custom XML format (designed by me).
The user should be able to add an image to the document, but I am having
trouble coming up with a strategy to save this to my file other than saving the
data inline.
Has anyone else done this before or have any ideas on a good strategy?
Thanks
Graham Labdon
