vb data through lightstreamer?

dianacastillo

I get an esignal feed through visual basic net. How can I send that data to my web page using light streamer? is it possible?

You send you data with Lightstreamer.
Lightstreamer keeps the HTTP protocol open all the time and let you consume the data similar to a web service. you need to use Lightstreamers client API for this. (and you should stop doing VB and switch to C# at least).

Diana,

Yes, that's possible. You need to develop a Lightstreamer Data Adapter for Esignal. You can use any .NET language to do that, by leveraging the .NET Adapter SDK included in the Lightstreamer distribution.

On the client side, you will include the Lightstreamer JavaScript API to make your web page live.

You can study the "General Concepts.pdf" document, especially the sequence diagrams on Adapter interactions. Then look at the Stock List Demo adapter example, referring to the JavaDoc for the Adapter interfaces. Unfortunately no examples in VB.net are available at present.
