Creation of Jpeg and upload through webservice?

[Chip]

Hi all,

A question or two if i may!

I am developing an application for use on the pocketpc 2003 (hardware
XDAII by O2). I have had a tinker with the compact framework but have
come up against a few issues!

The application needs to be able to perform the following:
Take images from a digital camera SD memory card, store them locally
on the device, manipulate the images into a smaller JPEG version and a
thumbnail too, then be able to upload the images to a web service.

JPEG editing: Can anyone recommend a 3rd party library that i may
purchase to perform the jpeg resizing? (or do i need one? can this be
done natively by the CF for JPEG -> smaller JPEG functionality?)

Image uploading: I have attempted this but get timeouts and other
transport errors ( i figure this is because i am base 64 encoding a
large file, making it even larger when serialized) . Does anyone have
any pointers on how to build a robust web service to allow image
uploads? I have thought about using DIME and compression but am unsure
as to how to proceed!

Any help very gratefully received!

Thanks!

If you have WSE 2.0 installed - there's a walkthrough that shows you how to
send a JPG as a dime attachment to a consumer - it's maybe 20 lines of code
total - well less than 40. Anyway, you will basically do the same thing in
reverse. On a scale of 1 to 10 it's a 1 - at worst - and the walkthroughs
have examples of securing it depending on how secure you need things to be.

Can't help you with the JPEG manipulation - not sure of any third party
tools out there...

HTH,

Bill

Hi,
Thanks very much for your reply - however when i attempt to use the
web.services2 in a mobile application my app warns me when adding the
reference and then throws a LoadType wobbler when executing! Any ideas
how i can get the attachment functionality to work on compact
framework?

Thanks
Chip

are you adding OpenNETCF.Web.Services2?
or are you trying to add Microsoft.Web.Services2?

try the sample code here:
http://www.brains-N-brawn.com/cfWSE2
it can call the WSE 2.0 DIME sample right out of the box.
