Re: Mobile Application
Ah, you crossed me up.
How will the PDA interface with the base station? Will you be putting it in a cradle using ActiveSynch? If so, I have done something like this using TCP, but it was for 2003, and much has changed since then. Another alternative, that has only become available relatively recently, is to use WCF. I'm not certain that WCF is available in the mobile CF, but if it is, it would be a relatively versatile solution. The BackEnd would expose a Web Service (I think even the name has changed from Web Service, but that's a good starting point) that you would then discover when using Add Service Reference in the mobile project. Of course, that depends on WCF being available to the CF. That WCF route would also work with TCP, as WCF is just a wrapper for a variety of different communication protocols.

Hi,
sounds ideal for Replication as we have been discussing at length in another thread.
There is a 'step-by-step' article here and an article I wrote on the device side here
Replication can be awkward to set up - but pays dividends in its ease of use when set up correctly.

Re: Mobile Application
That is the way replication (and RDA) works - using IIS server

Re: Mobile Application
so if i dont use IIS i wont also be able to use sql replication? my problem is that what im developing is PDA application and Gateway (connection to my PDA and Desktop) only.. I cant change or modify the desktop application..
the process is the desktop just give me text files and then my gateway process this text files and insert it to a SDF. thats on the upload process..

Re: Mobile Application
So if you can't change the way the application works, why ask the questions?
