Raising Events from Web service to clients

[Guest]

Dear All

I have a webservice which has reference to the ATL COM, as we know that ATL
COM of VC raises events i get those events in my web service of VB.net.

But now the clients will have a web reference to this new web service, n i
need to get the events raised from the web service to its clients.

could not get a possible solution for it.

had got some article in system.remoting but am looking for some broadcast
kind of thing which will raise events to the client.

Regards
Mary

Mary,

I believe there is a WS specification for eventing. Unfortunately, the
webservice architecture of ASP.NET doesn't support it, as far as I know.
WCF might have support for this, but this is a ways off, so that's not a
feasible solution.

In this case, you don't want to use web services, but rather, you want
to use remoting, which supports more than a request-response mechanism.

Either that, or you could create a service that you hook up to which is
out of band, meaning, the way you get notifications on the client (through a
custom protocol over a socket connection) is different from how you make the
requests (through the web service).

Hope this helps.
