File transfer alternatives

[Zeno Loco]

Hi,

I'm just starting thinking & developping a complex mobile application
in wich a great part of the work will be in communication between
mobile devices and servers.
I need to improve a mechanism of bi-directional file transfer
(messages, XML files, dlls, ...).

I'm now evalauating and testing the differents technologies in .net
compact framework :

- FTP
- MSMQ
- others ...

I would be really happy to have suggestions about your experiences,
tips, books, sites, technologies and any other thing than can help me
to keep the right direction.

Thank's

I work with XML and RAPI , because my PCClient doesn't any SQL Server
based database.

This works quites well and it already imports about many thousends
(15.000) Recors with some kind of packaging logic.

Some otherways could be Webservices, or even Replication if you are
using SQL Mobile and have and SQL Server on the host

You haven't really said why you need to improve on existing
technologies, what makes your app so complex, what are your performance
requirements, what volumes/types of data are you transferring, what
connection environment is your app working in ??

Hi Chris,

I'working on a GPS application and we have designed a dynamic and
interactive structure based on downlodable plug-in.
So we need to :
- manage the plug-in (dlls) distribution (versions, dependancies
between plug-in, ..)
- transfer maps and GPS files in both direction
- send/receive commands and events
- send/receive messages

The target device are, in this scenario, the largest possible part of
smartphones.

If you add the fact of very low-budget (actually we are
self-sponsoring) and the very little experience in mobile programming
you can have an idea of my difficulties ;-)

Thank you for your interest
