Welcome to the world of mobile computing. You're not the first person to
hit this, and the answer generally is that you'll have to write an app for
each device. There's no way to run a web app "disconnected" on most mobile
devices, so you need a device-resident app. AppForge Crossfire is worth
looking at, as it is "cross platform".

> I am student currently working on a project to produce a mobile solution
for a maintanence team. The solution must be able to handle both working
online when a wifi connection is available and offline when one isn't. It
has been reccomended to me to utilize web projects in visual studio .net as
this will allow rapid deployment across a vast range of devices quickly.
However using such a solution does not solve the problem of needing to be
able to use the system when a network connection is unavailable. Is there
anyway to locally cache and execute all the asp.net pages(to allow offline
access and functionality to the system) and then use SOAP services etc. to
synchornize local data to a centeral database.(Online and synchornization).
My understanding is that the asp pages need to be placed on a server and so
this solution is not a viable option. Instead it would be necessary to
create a client application for each specific device if it is to be used
offline, but this is time consuming to carry out for a number of differant
devices. Finally in general palm's are cheaper than devices that run pocket
pc, and therefore it is also desirable but not essential for a system to be
compatible to with a palm os yet i don't believe that there is a compact
framework for the palm OS. Anybody got any suggestions for the best design
solution to this? Or is it going to be a case of create seperate application
for each device changing interfaces etc and ignore the palm OS as .net is
our development environment of choice?
