Let's say I have an Ajax Editor which allows user to type or paste in long message or writting. Once he clicks on "submit" button, an HTML file will be created and save to a disk. I am working on asp.net 3.5, ajax version 3.5 (from codeplex, work well).
I have to save a .doc file on the server when the user clicks a button with no 'Open/ Save / Cancel' dialog box.
my code:
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.Charset =
"";
HttpContext.Current.Response.ContentType =
"application/msword";
[Code]....
The problem is that the user first sees a 'Open/ Save / Cancel' dialog box. Instead of dialog box, It should be automatically save on server.

I have searched the web for the answer and saw that mostly variables are saved in viewstate on page.prerender event. Then the value of the variable is set back in page load event.However, when I save a variable in viewstate on prerender or load events, how can viewstate store the value of the variable after it is changed dynamically on codebehind?
Let's say, after page is loaded, user clicked a button which changes the value of the variable in its onClick event. Then the postback event raised since the button was clicked. According to me, the new value should have been lost and cannot be saved in the viewstate if the variable is saved in the viewstate only in prerender event. Because on postback the prerender event wont fire and the value cannot be saved.
Shouldn't I save the variable in the viewstate just before the postback event rises?? If so, how can viewstate store the new value of the variable if the viewstate is saved in prerender event?
My Asp.Net calls a SQL sproc and returns a XML file as a string. This is what I need to do:

- pop up a dialog box asking the user which path he would like to save the file;

I am using the ajax control toolkit tabcontainer with 5 tab panels inside of it. Each tab contains areas where one must input information. The page also contains add, edit, and delete buttons with gridviews above them. What I am trying to do is to make the user save or cancel changes when they change the activetab. I am using a javascript confirm box but I need to try to retrieve the value of what is pressed from the javascript box to decide whether to discard the changes or stay on the page and make the user finish the input. Is there any way to save the value from the javascript box into a variable so or must i try something else?
PS I wasnt sure whether to post this in the javascript section or the asp.net section since im using asp.net with c#.This is kinda what im using but would like to turn it into a confirm box and pull the true or false value.
protected void TabContainerContent_ActiveTabChanged(object sender, EventArgs e)

My application is MVC Web App Chat Room , it supports following features:1.Create/Join/Close room 2.Send message in room (just live message, offline message might be supported in future)I have done logic for application, but I'm considering where to save chat room data (message,room information, and users in room) ? I see there are 2 options:1. Application variable2. Using file or database-What if I saved in Application variable:In case of there are 2000 rooms and 10000 users online, mean I have to persistence in Application variable (actually in RAM memory) information of 2000 rooms, more than 10000 message (text), these numbers might be increased by second if there are more users online in real time. and what's next ? I don't know what will happen to server, crash ? or my web app will be terminated ? whatever I don't want both results !
-What if I saved in file or DB (i.e: SQL Server DB) Because of web application, clients have to send request every 1 second to fetch data (messages and user list in room). So in case of there are 2000 rooms and 10000 users online, means they will make 10000 requests every 1 second to DB. I don't know what will happen to DB, there are a lot of connections and in EVERY 1 second, can DB still be alive to serve request ?I don't know where saving is good now because both seem are bad solution

Suppose there are three button and every butthon has a click event function.
Clicking the first button displays something on this page with a gridview taking data from databases.
After clicking the first button i stored the value in a variable.
But when i click the second or third button i get null value for that variable.
Clicking the second or third button the page reloads and the value of that variable becomes null.
How can i store the value to that variable permanently?

I want to write a page that shows the content of an rss feed. But I dont want to show only the current rss info but also previous. In other words I want to store every rss feed from the second I will finish building this page. The old and bad method is to refresh every 1 min or so, and compare the rss list to the db list. The rsses that doesnt showen on the db will be inserted.This method looks bad to me and I want some automatic method. What I mean is that when a new feed is posted it will send it to me (as a subscriber) and then it will inserted into the db.
How do I do it? And how do I do it behined the seance (in the global.asax or something?)?
