Thanks for the info. I converted the code in the VBScript to work in
vb.net and it works properly. I can extract the information I need.
I compared this way to to my original way with extracting the info via
an image object and this way is about 40% faster based on my tests.
Thanks!
You're welcome. I'm not familiar with the image
object. It may be very efficient. But I'm surprised
that the direct method is not more efficient. If
you're reading the whole file (into an array?) you
might find it quicker to just read part. Digital
cameras take *very* big photos these days, but
the file header should be fairly small. I usually
read up to 20,000 bytes and then provide for going
back for a second read if necessary, but I think
the 20,000 is probably enough in virtually all cases.
Even when there's an embedded thumbnail that's
usually just 3-4 KB.
