Dear Rui,
You may want to reply to my questions by private email rather than
discuss this is public ... send email to "andrew@trakware.org".
How complex is you application in the sense of data collection and
requirements ?
I ask because we have a development tool for PDA's, Hand Held Terminals
(ie: bar code scanners) and Smartphones. The software will allow you to
write quite complex applications and stores its data in a multiplatform
database format (ie: you could just copy the database off the PDA onto
your PC and use it - if you have the tools). The software allows the PDA
et al to automatically off load its transactions, and perform various
kinds of database syncs if required into any ODBC / OLEDB / CSV or Excel
datbase. We also support TCP/IP protocols in Batch, Wi-Fi, GSM, GPRS
(shortly Bluetooth) modes.
We support Win32 for the development tool and all Windows CE, Pocket PC,
Pocket PC 2002 - 2004 and Symbian Os's for the PDA's. Early next year we
will also support Palm and Linux.
As stated above, if you wish to discuss your requirements or how we
might be able to help then contact me privately via email.
