I want to redirect the user after 2 mins if there is inactivity for 2 mins. I am not using ASP.NEt membership. And I dont want to use Sessiontimeout for this. Session timeout will logout the user even if he is working on the system. My objective is like screensaver process.
If there is no action for the specified time, the screensaver runs. Similarly, I want to redirect the user to login page.
note that i have already handled it with the following javascript:
[Code]....
Here what my problem is,
the user is working on the site...ok.. he want to see someother site.he browse someother site and works on....or even he can do some other work in his system...but he is active in his system... What this script does is, it automatically logout the user and redirect him to login page. But it should not do while he is active...IT SHOULD REDIRECT IF HE IS NOT ACTIVE REALLY (Similar to Screensaver process)
Is it possible ?
if u add this to web.config, then if a page have gone through long process, the client will not have a timeout exception.
<httpRuntime maxRequestLength="1024000" executionTimeout="36000"/>

If you open a web page on one of the websites hosted on our server, and leave it for 20 minutes, and then submit a form, a "Validation of viewstate MAC failed." error occurs.
What possible reasons could there be for this?

View 1 RepliesI have a page that have a combobox and a button, when the user select something from the combobox and hit the Go button they are redirected to the page with the desired variable.
[Code]....
The problem appears when the page was not used from more than 20 minutes and the user select something from the comboBox and hit Go Button the receive a page indicating the Error 404.The only thing that I try is to use a javascript code that Refresh the page every 15 minutes but is not nice to see a page refreshing without a reason.If someone can have a way to identify what can be done in this problem, Its going to be a huge help.
I had a problem with my internet explorer where when i refresh page the submit button the a page would also execute which was leading to double entry of data . for that i had to right the code for the refresh page where it wud clear the cache and session or it wud not enter last session values .
protected void Page_Load(object sender, EventArgs e)
try
Session["DdlValue"] = DdlfacilityInsfindCsu.SelectedValue;
if (!IsPostBack)
Session["CheckRefresh"] = Server.UrlDecode(System.DateTime.Now.ToString());
GetDdl();

How to create create variables/properties in master page, and let sub-pages access them? So my master will have a string property HomeUrl How can any page that uses the master page access this property?
View 2 RepliesI'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.
View 8 RepliesIs is possible to build a form, accept parameters and from THAT construct a new .ascx page AND the code behind for that page? What I'm proposing is having some code snippets that just need parameters added and can then be used to create a web user control that can be added to existing pages. This .ascx file would be a real file after creation, not dynamic every time.

View 1 RepliesI'm having a problem with a web app I'm managing. Users starting receiving the following error occasionally:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.
The problem is that it's not a cluster - it's a single Windows 2003 server. After digging around, it appears that adding a machineKey section and some extra attributes to the Pages directive in my web.config resolves this error:
<machineKey validationKey='MACHINE KEY SNIPPED'
decryptionKey='DECRYPTION KEY SNIPPED'
validation='SHA1'/>
<pages validateRequest="true" enableEventValidation="false">
After changing these two things in my web.config, the error goes away, but now I have a new problem - Instead of an error that my viewstate is invalid, the app just "Forgets" who my user is, and sends them back to the login page. Now, the users are browsing through the application, and then they're unexpectedly sent to the login page, even after they've already been logged in for a few minutes. While I can't force this to happen, it usually happens within visiting 10-12 different pages, so pretty frequently.
I'd love a resolution to this - does anybody know what else might be causing the viewstate error on a single server, or what I can do to ensure that it's validated properly?
I have implemented the basic forms authentication.In web.config I have set the following, in the authentication tagtimeout = "50000000000" Other than that, I have an out-of the box implementation.I have no custom provider.My clients want to pretty much enter the username once a day.The timeout is in minutes, so I am sure that they are not waiting over 5 million minutes,so something else has to be booting them.

If I do not activate my application for 30 minutes (my customers wants to be online all day without logging out) my session for user login is lost. How can I automatically refresh my sessions if there has been no activity for e.g. 10 minutes? It's a sort of keep-alive that I want. I thought the problem was sloved when I set the timeout to 100000 but it doesn't help
Note. My application works with the remember me function but it losses its sessions after 30 minutes.
I'm building a website in ASP.NET with C# code behind files, I'll be using the site on shared hosting due to price, and one of my aims was to have a stored procedure scheduled to run every 1 hour in MySQL and update my database.
Unforunately security arrangements on shared hosting means that users cannot schedule stored procedures, so I decided to tackle the problem another way.
I created a timer in my website inside its own class file in the App_Code folder, it basically starts a timer and then the time elapsed event connects to my database and calls the stored procedure. I then built an admin page that allows me to see the status of this thread (started/stopped) and allows me to start/stop and restart it.
It's installed on my test site that I run from my home PC using Win7 and IIS, and it works beautifully, I can stop start the service and watch the database tick up when it's running...
HOWEVER...it only seems to run for 20 minutes before it stops, I thought maybe it was the garbage collection killing it since that's mentioned in some timer examples but I've added a GC.KeepAlive(Timer) and that's not . I'm really stumped as to what is stopping the timer, it's functionality is dead on the money and how I want it, but it just stops, always after almost exactly 20 minutes.
