push info to tablet

[mcorbeel]

I want to use a tablet for showing information that comes from a central db. I could do this with a webpage or even a webservice, but if data has changed this will not reflect immediate changes on the tablet, because the tablet will check the db on scheduled times. Another disadvantage is that there will be network traffic even if no data has changed. So I was hoping there is a way to either push info to the tablet, or a way to "poke" it and say "hey tablet, there is a change in info, go get it and display it, please...". Can this be done? What is best practice here?
Thanks for any reply!

This seems exactly what I need... Thank you (and thank you Google)

1 question though: the webservice is a php script ... but my webserver is a MS only server... so... Is there a webservice for ASP.NET? Is this code available somewhere?

I think that someone has created an ASP.Net version of this script (not 100% sure). The script is quite simple. It just saves the registered devices ids.

Any idea where I can find a VB.NET example? I googled but did'nt find much...

Sorry but I didn't find it.

It was classic ASP and it used a msAccess database

Maybe some use to you, maybe not.

In the meanwhile I discoverd that for my app it will be beter to use sockets. Since the tablets will be on the local network, I think it's better to have a direct communication instead of going through the internet, no?

 

[Erel]

It is simpler in the local network. See the HttpServer chat example for another option.

 

[mcorbeel]

This is indeed simpler than sockets... Thank for the advice!

Hello,

I'm currently working on a MS SQL to android push app. It is optimized in using as less data as possible. It works on Sql Express versions and up.


Might still take a few weeks to complete though.
