Line 31: {
Line 32: con.Open();
Line 33: Label1.Text = Session["name"].ToString();
Line 34: string a = ("select name from user2 where name='" + Label1.Text + "'");

When user logout, we redirect him to the login page. I show a message "You have successfully logged out." on login page using query string. But when user refresh the login page the message still appears. How can I make sure during subsequent refresh, the login page should not show logout message. Here is the code:
On buttonSave click after saving the record successfully ,I want to show "Save successfully " message on a label on a page for few seconds and then reload the page.

I receive this error when running the application. It is the LogOutPageUrl from the login/logout control. I have substituted several different destination pages, which all work in any other part of the application. However still get this error? what may be causing this, or why none of the other pages I have used will work either? Description: HTTP 404.

I am Creating a Webapplication. In that i kept Login options where users can login. Some users access the data without login. I want when user want to access without login it should redirect to login page.
In logout link's click event i have written Session.Abandon() that will destroy the Session state.I am also handling Session_End event that is fired afterward (written in Global.asax). But one more thing i want is that after Session ends, login page should be redirected (opened).
For that i wrote:
[Code]....
This is working fine on the surface, but after applying debugging i saw that there were unexpected number of calls to Session_Start and Session_End events for two times, then login page was opened.
Why Session_Start and Session_End was called two times ? If i left this process as it is working then may i get some serious error in future ?

I have an option in my website to logout from session and redirect to login page. So I get redirected and if I try to login again it seems like it tries to redirect me to login page over and over, until I click some page in menu and login and it does works. so, doesn't the login control always redirect to same DestinationPageUrl? here the logout code:
After about 10 mins my web app will give me an error when i logout or try to save page. I have the sessions set and dont understand why I get this problem.in webconfig i have this.
I have a login status object on each page for logging out. Clicking on this object will logout the user and navigate to the login page. I would like to set it up when a page is loaded, if certain conditions are met the user will be automatically logged of and redirected to the login page. If I could just somehow have the program click on that object, that would do the job.
When I add an update command to my page and run the page I get this error message

I have a Web app using Forms authentication. I Use Timeout in Web.Config to TimeOut from application that is working fine and I am Redirected to Login page with Message on page "The application timed out. Please ClockIn/Login." When I am Logging again I am Redirected to the same page with same error message and after that if I try Logging again second time I am able to Login.
Following is the code from different form which i am using.
I'm starting with the prebuilt ASP.NET site in VS 2010. The login page gives the following error message if login fails: "Your login attempt was not successful. Please try again."
I have written custom code for login and logout...When use clicks on logout button the current session is closed and user is redirected to a login.aspx page...The problem is that when a user click a back button on internet explorer it the previous page he was navigating is shown to him...(altough he cant perform any operation as session is null and their is condition in page load that if session is null user should be redirected to login page)May i have to clear cache of client ??
I am wondering how I can implement so that later login session logout former login session to avoid concurrent login. I know how to check whether the user is online (by Membership.IsOnline()) and logout the current user (by FormsAuthentication.SignOut()). But I don't know how to logout the previous login session.
