View 1 RepliesState Management :: Send Variables To Another ASPX Page

The first way is the use <form> and <input type="hidden">
The second way is the put the variable(s) in the URL such as http://www.joesmith.com/Sample.aspx?var1=bob&var2=cunningham
Is there a 3rd way to send variables using VBScript inside the <script runat="server"> tag?

State Management :: PageOne.aspx Uses Pagetwo.aspx Session Variables And Datatable Contents?
Mar 24, 2011I have done a web appllication and when run simultaneously from different locations, the one that is started first would use the one that is started late's session variable and datatable contents. This is an exams web app and pageone.aspx results should never be used for pagetwo.aspx's results, because they are not the same questions.
What can I do to prevent this from happening. I am desperate, people are standing by to do exams and time is not on my side.

Mar 7, 2011I have a static HTML page complete with client-side scripts and css (both are included in the html).

But i am asking if this could be directly managed from the web aspx page...?
State Management :: Session Variables Destroyed With Each Page Load?
Apr 22, 2010I'm using the beta version of Visual Studio 2010. I'm running my ASP.NET 4.0 website through the debugger. Whenever there is a page load (e.g. clicking on a link, a postback) the session is ended and a new session is created. This wipes out all the session variables and makes debugging impossible. How to get session variables to persist across page loads?
Is this problem unique to running ASP.NET in a test environment or unique to the beta 2 version of VS 2010?

State Management :: Set Session Variables In One Page And Retrieve Them In Code File?
May 12, 2010I'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"))

C# - Static Variables In WCF?
Feb 13, 2011I have some WCF services. These services run in ASP.NET. I want these services to be able to access a static variable. My problem is, I'm not sure where the appropriate server level storage mechanism is. I don't want to use the database because of speed. But, I want the static variables to stay in memory as long as possible. In fact, I'd like it to stay until I restart my server if it all possible.
View 2 RepliesC# - Assign DTO Properties To Public Variables Or Call The Dto Instance Directly On Aspx Page?
Nov 3, 2010My UI layer calls my business layer which populates a DTO. I need to display properties from the DTO on my ASPX page. Should I create public variables on the code behind page for each of the DTO properties and reference like <%=PublicPropertyName%> OR is it ok to set the DTO instance to public and reference the properties directly like <%=dtoInstance.propertyName%>
Additionally, would it be better if I just created Literal and Label controls for every item on the ASPX page and just populate them from the code behind only?
.net - Session Variables Clearing On Response.redirect ('page.aspx",false)
Mar 1, 2010I have an webforms app that loses it's session variables on response.redirect. I've read Bertrand Le Roy's blog about this and still can't get it to work. The page works in production. However, when I try in the VS2k8 IDE, the session variables are there right before response.redirect and on the first line of the next page, the variables are nothing. I've confirmed the session id is the same so I'm not skipping sessions. The target page is relative so the web server doesn't think we're changing sites (as confirmed by the sessionid).
Response.Redirect("menu.aspx", False)
Web Forms :: Static Variables Throughout Application
Oct 6, 2010i am developing a website in asp.net i have created a class "Utility" in App_Code Folder this class contains a static object of another class(LoginInfo) as described below:
[Code]....
This LoginInfo Class is my business object which only contains 2 properties UserID and UserName
Now what i am doing on my login page, after user authentication i am setting these properties with current logged in UserId and UserName
[Code]....
I am using this CurrentUser object on my webpage to get userid and username. It works fine, but after few minutes my CurrentUser.UserID and CurrentUser.UserName is set to blank string. I am not able to figure out what is the problem. may be due to asp.net recycles.

C# - Will Static Public Variables In App Get Shared With Other Users In The Same App
Nov 11, 2010For reasons I would rather not discuss, I need to create a custom authentication system for my app. I was just reviewing the system and am having some doubts if my solution is thread safe. My goal was to create a solution that would allow my app to authenticate a user one time and that users authentication info would be shared by all master pages, pages, classes, user controls, etc that are used. (But not share the same info between users) Here is my setup: PageHttpModule.cs - this is added to the web.config as a httpModule.
public class PageHttpModule : IHttpModule
{
public void Init(HttpApplication app)
{
app.AuthenticateRequest += new EventHandler(OnAuthenticateRequest);
}
public void OnAuthenticateRequest(Object s, EventArgs e)
{
CurrentUser.Initialize();
}
public void Dispose() { }
}
CurrentUser.cs
public static class CurrentUser
{
public static bool IsAuthenticated { get; private set; }
public static string Email {get; set;}
public static string RealName {get; set;
public static string UserId {get; set;}
public static void Initialize()
{
CurrentUser.AuthenticateUser();
}
Note: this is a scaled down version of my authentication code.
public static void AuthenticateUser()
{
UserAuthentication user = new UserAuthentication();
user.AuthenticateUser();
if (user.IsAuthenticated)
{
CurrentUser.IsAuthenticated = true;
CurrentUser.UserId = user.UserId;
CurrentUser.Email = user.Email;
CurrentUser.RealName = user.RealName;
}
}
}
UserAuthentication.cs
public class UserAuthentication
{
public string Email { get; set; }
public string RealName { get; set; }
public string UserId { get; set; }
public bool IsAuthenticated { get; private set; }
public UserAuthentication()
{
IsAuthenticated = false;
Email = String.Empty;
RealName = String.Empty;
UserId = String.Empty;
}
public void AuthenticateUser()
{
//do some logic here.. if the user is ok then
IsAuthenticated = true
Email = address from db
UserId = userid from db;
Realname = name from db;
}
}
I have tested between 3 different browsers and it seems to work fine, but I am still learning and don't want to make a huge mistake. If my logic is totally wrong, then how should I do it so I dont have to put user lookups on every page directly?

I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).
