Data exchange over wireless (best practice)

Hi all!

I'm a developer now for some years, but I've just started to develope for
mobile devices. My problem is that I need to develope program for PocketPC
(Win CE) that would read a barcode and the send the data over wireless to
database server.
I know how to read a barcode but I need some insight in what best practices
are to exchange data with database server.
I currently have a web-service on IIS that comunicates with database and has
two methods exspoded (GETdata and UPDATEdata) that are visible to other
aplicatons. This data is sent over the LAN in dataSet object (not string
etc.) - the problem now is that Mobile devices project in VS2003 (C#) has no
data-set object so I can not call those rwo methods on web-server.

Again, please if anybody would be so kind and explain how are this kind of
projects/problems handled. Any kind of info would help.

Thanks and best regards,
Smiljan

Hi Smiljan,

Compact Framework 2.0 should support typed Datasets and CF1.0 untyped
Datasets.

Your approach in using a webservice should fine. You should also consider
making allowances for offline processing and possibly storing your data in a
SQLCE database or in a XML file.

When the user is connected successfully, any new data to send to the server
can then be picked up from the database and sent through the Web service. It
provides better usability this way.

There should be lots of articles on the internet that discusses these
fundamental approaches...

Winston
