Client Chatting th a server.

[Guest]

I am trying to create a chat application in the browser.
I need to find a way for the client to call back every 15 seconds.
I tried <meta id="meta" http-equiv="refresh" content="15" />
But I am not getting any viewstate with the above trick.
Does anyone have any good ideas?

Hi Arne,

When you refresh a page, you are calling the page via GET, not a POST.
This is the reason that you get no viewstate. To do it you have to
change meta refresh to a JavaScript that would submit the form every
15 seconds.

Where do you need to have the viewstate? I think in a chat you need to
get new messages only, so you don't need to post anything every 15
seconds.

Hope this helps

The JavaScript setTimeout method is commonly used for such matters.

Steve,
The webchat example is just wonderful. I guess I should show my appreciation
by buying a copy of your book.
Now I have another requirement.
The clients should not talk to each other but to a customer service rep. I
was thinking the rep should have a winform. The webclient should keep in
contact with the winform with WCF.
Any more good ideas?

Webchat could be modified to do such a thing.
Since it uses AJAX calls back to a web service, a winform front end should
be able to call the same web service theoretically. Then you can have two
front ends.
