Alexander,

Thanks for quick the reply. Its very much appreciated. At
this point I'm desparate for any help at all.

Unfortunately, I can't seem to get to the link you posted
below. However, a quick search around the web lead to
a number of interesting examples of "Serialization". With
your help I now have a focus for my R&D efforts. :)

For instance.

To answer your question about what we hope to do with
the byte[] array afterwards, we have a large archive of
PDF format documents stored in our database.

I need to convert the PDF document extracted from the Acrobat
Scanning process into a byte[] array before I can insert it
as a blob into our database.

We developed technology years ago that automated Adobe Acrobat
from our C# data entry application. Because of our lack of
sophistication / knowledge of interop practices we ended up
passing documents back and forth between Acrobat & our data
entry application by using a temporary .pdf file on the local
hard drive. The temporary file approach has worked, but it
leaves a lot to be desired. As a result I'm trying to figure
out if there's a way to pass PDF documents back and forth
directly between Acrobat and C#. Being able to retrieve
scanned documents directly from Acrobat would save us a
tremendous amount of problematic 'Rube Goldberg' style
code.

You can see an example of our PDF doc archive by clicking on the
12345 certificate number at the following URL.
