the idea id I need to send data to the client to the server to inform the server of some events at the client, and i need to send data from server to the client to inform the client of some results on the server. now from client to server is easy I use xhr easy enough. and to send data from server to client I thought of using long polling in xhr so to test I wrote the following code:
[code]
<!-- Test.aspx -->
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>

I am using the System.Timers.Timer class. And I enable when I send a message and disable when I receive the message. How do I calculate how much time has elapsed. I have set the interval as 1 sec
Basically I retransmit data after 1000 sec again if I do not recive an ACK. I retransmit 5 times max until I get a Ack. If I receive and something before 150ms then I stop retrnsmission.
Here's the code:
timer1.interval = 1000;
port.Write(data)
timer1.enabled = true;
event handler for the received data.
timer1.enabled=false;

I know that I can receive an javascript object from the server via ASP.NET AJAX using Json. But I am not sure how can I send an javascript object from my client-side javascript to my server-side code. And if I can, how can I extract this object in my server-side code and access its members?

I have a simple question - I use update panel with custom server control inside. I call __doPostBack from javascript and RaisePostBackEvent on the server fires (I implement IPostBackEventHandler).This is client to server call. Could I return data back to the client (after this partial postback)? What is the best way to achieve this?

I'm completely blanking here. I've got 2 servers that cannot talk to each other via normal network traffic (like just copying a file). I can't get FTP setup on either server due to artificial company security constraints.Server1 basically just has an exe on it that I have written, and it needs to send a file to Server2.Server2 has a full blown asp.net website on it so I'm writing a .ashx page to handle receiving the file.So...Server1 needs to make a call to server2 and send a file to it over http. Server2 needs to accept the file and save it to disk.Where should I start? I know I can make server1 create a WebRequest object, and set the methodto POST, and then stream the content.But on server2, what am I supposed to write? A generic handler? Will my file that I send be part of the context.Request object? How do I get it out?

I have a website written in C# and when a user does something I want to be able to send an IM message to an admin and allow the admin to respond to approve/deny the request.
I would like to use something like MSN Messenger or AIM so that the IM messages can also be sent to phones as sms.

I'm trying to receive a Client Certificate in a Web Service and having some problems.
Client
[Code]....
The certificate seems to be correclty loading and added to the client.
The client connects to the server with HTTPS.
Server:
[Code]....
cert.IsPresent is false and all certificate fields are empty.
IIS is configured to Accept Client Certificates.
Reproduced in two environments:
- Windows 7 x64, IIS 7, VS 2008, .NET 3.5
- XP x86, IIS 5, VS 2008, .NET 3.5
Always in the Web Service the Client Certificate is not proesent. I haven't been able to find any other configuration I should do.

I've been stuck on this one for a while, so it's time to consult the pros. I've created a charting application that uses javascript to do heavy DOM manipulation/generation on the client (creating barcharts made of colored divs, etc).
Long story short, I want to avoid sending my js library to the client. Is there any way to create the content on the server, using my existing javascript library, and only send the javascript-generated HTML to the client?

I need to send a cookie to the my web site's visitors and receive them back for information. For example when machine1 visits my site if not set I set a cookie with "user1", for machine2 I set "user2" etc.
Actually I need to retrieve the cookie back from my log file, so I thought if I do this it will be saved to my log file.

I'm looking for possible ways for sending files from browser to server.
One obvious way is using form with enctype='multipart/form-data'.
I wonder if there are other ways than this.
The reason I ask you this question is this file uploader: http://aspnetajax.componentart.com/control-specific/upload/features/core_features/WebForm1.aspx
It's not flash based, but it sends the file in a way that it gives you a progress bar, but when you send a file with form with enctype='multipart/form-data' the whole file will be send to the server so you can't actually show a progress bar of uploading process.

The user clicks on a button on a page and as a result he gets a new page send back.
Most times everything is fine now, but sometimes this page needs to be updated within a few seconds but the user don't knows this.
I know I can poll from the client site with reload, but this does not fit here.
I need a kind of push update from server to client ... the action must be initiated from server, not from client ...

I have a ListView that contains a large collection of rows with textboxes that users can optionally fill out. These textboxes are not databound. When the user clicks "next" i need to iterate over the rows and determine which fields the user has filled out, and then update a sort of "cart" with the data and move to a confirmation page ("you have selected a, g, v, zz, is this correct?" sort of thing).
I can think of two ways to deal with this. The first is, server side, to walk the items in the listview, get the control ID's, save this data to a list, then save it to a database cart table for the next screen to read.I can use jquery to collect all the values client side, then pass it back to the form in a hidden field and use something like Newton.Json to get the data into a similar list.What are the tradoffs of these two approaches?

I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.
I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.
However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.
