Web Forms :: Parse Session Value To Retrieve Correct Article
Jun 1, 2010
I have taken up a project at work that was left half finished by the last guy that used to work here, it involves choosing a country, region and town from some drop down lists this is all done in Javascript which leaves this as a problem for me so now I need to retrieve the value of the townID that is stored in a hidden value, I tried this by putting the townID value inside a session and then on postback (after clicking the button) I wanted to parse the session value to retrieve the correct article, but I receive the following error:
Value cannot be null.
Parameter name: String
Here is what I am doing with the code (on the button):
[Code]....
(Postback)
[Code]....
This is the code I am using, the TownID is coming out null!

I'm trying to parse a HTML file to retrieve certain info in my asp.net app. I've looked at the html agility pack but found that also quite difficult. :-) As my HTML should be pretty standard I'm hoping regex is quick and easy. I need a regex that will look through the html file (which I've loaded into a string) and find the below line and take out the DATATOEXTRACT (which will be some sort of text, the name of a recipe in this case) so I can put it into a variable:
<span class="titleText1">DATATOEXTRACT:
</span>

I new to .aspx and now the thing is since i am doing a web enabled project, I have this login from an user. I drag dropped the login template and then used the
Session["Authentication"] = username.Tostring();
to store the current logged user's info and so. Now i even used a hyperlink "Logout" at the top right corner and then made it transfer to Login page.
Now if on running the web , i can easily login , but when i logout through hyper link "logout" it will take me to the Login page again, but if i press the back button of the browser it again transfers the control to the data page and i can again perform the data operation's.
I used this
Session["Authenticate"] = null
at the page load of the login page so that only at the login button click the user can enter again by
Session["Authenticate"] = username.Tostring();
Then i used a check at each page load of the data pages
if(Session[Authentiacte"] == null)
Server.Tranfer("LoginPage.aspx");

How do I implement this session: (UserID is part of the login table)
Session["UserID"]="usrName";
Into this code?
using System;
using System.Data;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.Odbc;
using System.Data.SqlClient;
public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Login1.Authenticate += Login1_Authenticate;
}
protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
{
//database connection string
OdbcConnection cn = new OdbcConnection("Driver={MySQL ODBC 3.51 Driver}; Server=localhost; Database=gymwebsite; User=x; Password=x; OPTION=3;");
cn.Open();
OdbcCommand cmd = new OdbcCommand("Select * from User where username=? and password=?", cn);
//Select the username and password from mysql database in login table
cmd.Parameters.Add("@username", OdbcType.VarChar);
cmd.Parameters["@username"].Value = this.Login1.UserName;
cmd.Parameters.Add("@password", OdbcType.VarChar);
cmd.Parameters["@password"].Value = this.Login1.Password;
//use asp login control to check username and password
cmd.Parameters.Add(new OdbcCommand("@UserID", 'id.int'));
OdbcDataReader dr = default(OdbcDataReader);
// Initialise a reader to read the rows from the login table.
// If row exists, the login is successful
dr = cmd.ExecuteReader();
int id = cmd.Parameters["@UserID"].Value;
Session["UserID"]="usrName";
if (dr.Read())
{
e.Authenticated = true;
Response.Redirect("UserProfileWall.aspx");
// Event Authenticate is true forward to user profile
}
}
}
I need to be able to retrieve the correct UserID when some one inputs there username and password upon login and then some how retrieve it on a new page something like this to retireve it but unsure?
string usrName = Convert.ToString(Session["UserID"]);
I just dont know how to add the first part, the session into my login code so I can some how store the UserID in my session but also retrieve the correct UserID from the submitted data that takes from my mysql login table.

my solution currently has a website project and a class library project. I am attempting to access a session object from my class library but it is always returning null. In a settings class in my class library I store these values like so:
private static SessionProperty<WebUser> _currentUser = new SessionProperty<WebUser>("CurrentUser", delegate { return new WebUser(); });
public static WebUser CurrentUser
{
get { return _currentUser.Value; }
set { _currentUser.Value = value; }
}
I can access this just fine from any aspx page codebehind like so:
Settings.CurrentUser.User.ProviderUserKey.ToString();
However, if I attempt to do the same thing from a class in my classlibrary project it always returns null.

My problem is regarding title written above. Currently I have some functions that rely on Sessions to do the job. Everything works smoothly when it is left to default. However, I do not like the idea of losing sessions in case of crash and I have modified my web.config to use Sql Server mode instead.
I have run the necessary commands to create tables and stored procedures in my database using aspnet_sql.exe. I am able to store values into the database but have not been successful retrieving them. Since it has been working fine with InProc mode, I think I can safely assume that there's nothing wrong with my codes. Here's my web.config setting:
<sessionState mode="SQLServer" allowCustomSqlDatabase="true" cookieless="false" timeout="120" sqlCommandTimeout="30" compressionEnabled="true"
sqlConnectionString="Data Source=.SQLExpress;Initial Catalog=mytest;Persist Security Info=True;User ID=mytest;Password=mytest;"/>

I have read in many places that referencing IRequiresSessionState or IReadOnlySessionState will allow me access to the Session scoped variables from within the ProcessRequest method in an ASHX file.
I have implemented these changes, as follows, and I am unable to retrieve this data still, as the server returns a null object reference error:
using System;
using System.Web;
using System.Web.SessionState;[code]....
The error is most certainly specific to pulling data from the session, yet I am 100% certain that the session contains data in this key.
It shouldnt matter where I am storing the data (cookies, vs db, etc), right?

I'm trying to set session variables in one page, and retrieve them in my code file in the page that it posts to.
I keep getting this error. I put the correct namespaces in, and enabledSessionState = true to my application files, but no luck.
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration><system.web><httpModules> section in the application configuration.
I'm just calling a session variable, and I get that error
e.g,
Public AUID As Integer = Convert.ToInt16(Session("AUID"))

I am having issues implementing SqlSiteMapProvider using the Wicked Code article. I am using VB.NET and SQL Server 2008 - and the OnSiteMapChanged event is not firing (the SqlDepdencyCache just seems to simply be not working at all). The article states "You also need to run the ASP.NET worker process with dbo privileges for SQL Server 2005 cache dependencies to work automatically.)" I don't understand what this means. I know what the ASPNET user account is and that it runs aspnet_wp.exe which is basically the ASP.NET run time as I understand it. I know what DBO privs are on SQL. But my SQL and web servers are on different machines, and ASPNET is not a domain account. And it seems crazy to make it one to try to simply get the SqlDepdencyCache to work, and I have trouble believing everyone is doing this?Anyone have any clue what I'm missing here?
