How can I prevent the user from again logging in by clicking the back button. In my web application, after signing out, if the user clicks on browser back button, he can access the main page again.
|
|

|
|
Try with the Session. If the User sign out close the Session.

It's depend on your implementation.
* If u save the login credential in session or cookies. Then can set the nothing for the Session variable and clear the cookies.
*If u r varify login information only first time when user logged in then u can disable back button by bellow code.
U can use below code. This will not be cach any page on loca machine. then i think it should be work as disable back button.
If u have other problem let me inform.

You should not block the back button of the browser using some javascript. In every page load check that the session exist. If not redirect user to login page. When logging out clear the session. By pressing the back button you are seeing the browser cached page. If you are checking sessions on page load, user can't do any processing with the page. When the page posts back, it will check for session and will be redirected to login page.

Yes sir you are right that "we should not block the back button of the browser using some javascript" because javascript can be disable for a browser.
As you suggested to check the session -- I am using Login control and form authentication, and after successfully logged in i have checked to count number of session available, but result found 0, because it keeps all information in a cookie. There is no any session. then how can i prevent to see the page before logged out.
If i manually set a session when user logged in and kill the session on logged out, then also someone can see pages (may contain confidential information) which was opened before logged out. Am I Right?
Then what is the proper solution to prevent see the confidential information opened during any one logged in??????
This Question was made too much earlier, So I think now u found the proper solution.
Please tell me sir.....
I am waiting for your reply...
Thank you in advance

I am not sure I got your question. But using sessions to keep login information is a standard practice. Sessions are stored in the server memory and unique for each users.

Do you mean when user presses back button? There are no efficient way to prevent the back button. You can do it using JS, which is not reliable. One solution I see is to open the users secured pages in a popup window, and close this window when user logs out.

There are good TWAIN SDKs available to purchase. I'm assuming you don't intend to handle scanning within Internet Explorer ? This is teh ASP.NET forum.

Do you mean 100 tables. ?  A dataset can contain tables. But not rows.
I assume that you have a datatable that contains 100 records and you want to take records between 5 to 10. So the code could be something like this
for(int i=5;i<=10;i++)
{
Response.Write(YourDs.Tables[TableName].Rows[i][YourColumnName].ToString());
}

Navaneeth. wrote: A dataset can contain tables. But not rows.
I think he want to say that Dataset contains 100 records means indirectly Dataset Contains one table which have 100 rows
so
!!! posted code is right 
Thanks and Regards

Hi,
I have been getting timeout errors for displaying my data. I used this code:
using System;
using System.Collections.Generic;
using System.Text;
namespace MyAdapters
{
public partial class working_step_a00TableAdapter
{
public string ConnectionString
{
get
{
return this.Connection.ConnectionString;
}
set
{
Connection.ConnectionString = value;
}
}
public void SetCommandTimeout(int timeout)
{
foreach (IDbCommand command in CommandCollection)
command.CommandTimeout = timeout;
}
}
}
And in the page load section, it has:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using MyAdapters;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
this.working_step_a00TableAdapter.SelectCommandTimeout = 300;
}
}
It doesn't understand 'using MyAdapters;' and it does not seem to work. What I am missing here? Thanks for your help.

Where is the class ?

Is SelectCommandTimeout static ? I don't see it there, at all.
