In class file session is not working properly.....

As I'm sure you are well aware, static properties values are shared (hence I believe the VB keyword for it) among all the application's instances. Which means your application is seriously flawed if you expose user data to other users.
The answer: don't use static properties the way you do.
Use normal properties.
And don't mean to be rude, but it seems your project is far away from completion, if you want it to work correctly.

I agree with Greg. You are using static keyword without knowing how it works. Static variables will stay in memory until the application domain unloads and it is shared between all threads under that application domain. To solve this, Use session variables. These are unique for each visitor.

But how can I used session variable in class file, its through "Objects reference not set to be instant of an objects". Please check my class file.
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.SessionState;
namespace MyStore
{
public class GetConnection
{
static string _conString = null;
public GetConnection()
{
//
// TODO: Add constructor logic here
//
}
public static String DBConnectionString
{
get
{
if (HttpContext.Current.Session["ConnStr"] != null)
{
return HttpContext.Current.Session["ConnStr"].ToString();
}
else
{
return "";
}
}
set
{
HttpContext.Current.Session["ConnStr"] = value;
}
}
}
}

The way you do it is overkill, and it's flawed.
You should pass the connection string to the constructor, get rid of the static keyword for the DBConnectionString property, add a private field _dbConnection and assign the value of it to the parameter you get in the constructor.
public class GetConnection
{
public GetConnection(string connectionStr)
{
_dbConnection = connectionStr;
}
private string _dbConnection;
public string DBConnectionString
{
get{return _dbConnection;}
}
}
}
It's still overkill.
Having a class with one string property that you set to something you already know.
As you have the connection string (hopefully stored in web.config), just fetch it from web.config everytime you want to connect into the database. In other words, don't keep the whole connection string in a session variable, but rather a key to fetch it by.

The following are the test urls, i need to remove the "Admin" from the URL. So I want the regular expression to solve this issue
http://www.Admin.testsite.com/Administrator/Login.aspx
http://Admin.www.testsite.com/Administrator/Login.aspx
http://Admin.testsite.com/Administrator/Login.aspx
http://quality.Admin.testsite.com/Administrator/Login.aspx
Once we remove the "Admin" word or text from the above URL , output would be
http://www.testsite.com/Administrator/Login.aspx
http://www.testsite.com/Administrator/Login.aspx
http://testsite.com/Administrator/Login.aspx
http://quality.testsite.com/Administrator/Login.aspx

Try google, there are thousands of regex sites where you can try and test to your hearts content.

i have implemented this code on the logout button
FormsAuthentication.SignOut();
Session.Abandon();
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1d);
Response.Expires = -1500;
Response.CacheControl = "no-cache";
Response.Redirect("~/frm_default.aspx");
but when i click on back button i am able to go the previous page.
|
|
|
|
|
i think u have to add Headers to restrict Back view
Try this
Response.CacheControl = "no-store";
Response.AddHeader("Pragma", "no-cache");
Response.AppendHeader("Cache-Control", "no-store");
|
|
|
|
|
if u r using master pages, code this in page load of master page or in page load of everypage
Response.Expires = 60;
DateTime now = DateTime.Now.AddMilliseconds(-1);
Response.ExpiresAbsolute = now;
Response.AddHeader("pragma", "no-cache");
int timeout = (Session.Timeout + 1) * 60;
Response.AddHeader("Refresh", timeout.ToString());
Response.AddHeader("cache-control", "private");
Response.CacheControl = "no-cache";
if (Session.IsNewSession)
{
Response.Redirect("~/Default.aspx");
}
and in logout
Session.Abandon();

This is fine but then when i am on a page (not logged out) and then i click back button it does not take me to the previuos page. ihave to click refresh to get the page.

browser cache always remains open..
you cant erase bowser cache programmatically.
Only you can do, is when user clicks anything on a page after logoff, throw some error messages.

Hi,
On the Page Load write
if Session("UserId")="" then
Response.Redirect("Login.aspx")
end if
if you click back now, the page will execute the page load na...it will go to login page.

I am trying to start/stop a windows service in the code from a web application.The web application runs as IUSR_ComputerName, but this account does not have enough access rights to star/stop the service.
How do I impersonate the local system account, so that I can stop/start the service?

You can use the AjaxControlToolkit
With it you can assign a calendar to a textbox with almost no code at all
