[RESOLVED] backgroundworker

[arkiboys]

Hi,
There is a fully working .net windows application which uses the background worker process in the form.

Using my new silverlight 4 application, I now would like to make it use the functionalities as the application in the winform i.e. background worker, etc...

Question:
As I am using the wcf to retrieve data and pass to the silverlight page, how/where do I use the background worker process? Do I use it in the service or in the silverlight page?

Alternatively, should I just have a timer in the silverlight page which calls the wcf every second or so to update the silverlight page with data?

Thanks

The background worker goes in the Silverlight page, because that background worker prevents the page from beeing blocked.
You shouldn't use a timer, use events (from the backgroundworker) to udate the data.
Alternativly you could use a async call to the WCF service

I think I should use a timer so that the wcf method gets called every few seconds.
Don't you think?
Thanks

Why would you call the WCF service every few seconds? Sounds like you need a duplex binding

[arkiboys]

Processing is needed to be doone every few seconds.
May be it is best to have a windows service which can be started. And have a timer in the windows service which does the processing every few seconds.
What do you think?
Thanks

There is almost no good reason for polling. Where does the service gets its data from?

Solved by having a windows service to do the processing and the WCF to pull th edata out of the windows service into the client.
Thank you
