Working With Static Variables / Store The User Specific Information In Static Variables?

Mar 5, 2011

whats the exact use of static variables in overall programming in .net and for asp.net...

Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..

whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.

Javascript - How To Embed A Static HTML Page In Aspx Page

Mar 7, 2011

I have a static HTML page complete with client-side scripts and css (both are included in the html). I was wondering if it would be possible to embed this HTML page into an ASPX page and have the ASPX page be able to respond to javascript events that are raised from within the static html document? Does asp.net provide a specific control for this or can I use a frame?

Access Static Class Properties From Aspx Page?

Jan 28, 2010

I am on .aspx page and i want to take the width and height of a control from a static class
where i have defined them as constans.

Is there any way to access that class directly from the aspx page?

I know that i can make a method like:

width="<%= getWidthSize() %>"

and inside the aspx.cs to define this method to take the size from that static class.

But i am asking if this could be directly managed from the web aspx page...?

State Management :: Send Variables To Another ASPX Page

Apr 24, 2010

I know there are at least 2 ways to 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?

C# - Static Variables In WCF?

Feb 13, 2011

I 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.

C# - Assign DTO Properties To Public Variables Or Call The Dto Instance Directly On Aspx Page?

Nov 3, 2010

My 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, 2010

I 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, 2010

i 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.

Optional Variables In Public Static Void?

Jun 22, 2010

Let's say I have the following;

public static void TryOut(int intOne, int intTwo, string strone, string strtwo){....}

And after I created dll, I will use it like that;

TryOut(1,3,"bla bla bla", "bla bla bla");
But I want the last variable to be optional. I mean this method could be used like that;
TryOut(1,3,"bla bla bla", "bla bla bla");
And Also like that
TryOut(1,3,"bla bla bla");

I know it is possibel but how I could do that I have no idea !

C# - Will Static Public Variables In App Get Shared With Other Users In The Same App

Nov 11, 2010

For 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?

State Management :: PageOne.aspx Uses Pagetwo.aspx Session Variables And Datatable Contents?

Mar 24, 2011

I 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.

Architecture :: Finding Pros And Cons Of Static Classes And Variables (particularly A Db Connection)

Jan 11, 2010

So I started working on my first asp.net application that involves logging in and databases, and soon after i started messing around with a static class. I "discovered" that if you make a variable static, all sessions share that variable (I for some reason was originally assuming that each session had its own copy of that "static" class). Anyway, after discovering this I thought to myself "how could this possibly be useful to me" and thought that itmight be a good idea to make a single static database connection for all of the sessions, rather than storing that as a session variable for each session. Does anybody know what would be the pros and cons of this approach?

Entity Framework - Is Using Public Static Variables For Compiled Queries Bad In Applications?

Aug 19, 2010

I'm coding a business layer for an ASP.NET application. I've created database methods in my BLL as static. I've created public static Func variables to be compiled and used in several different methods, like this:

namespace BLL
public class User
{
public static Func<Context, variable, result> selectUser;
private static void CompileQuery()
{
if(selectUser == null)
{
selectUser = CompiledQuery.Compile......
}
}
public static UserClass Select(int id)
{
CompileQuery();
//uses selectUser
}
public static SomethingElse DoSomethingElse()
{
CompileQuery();
//also uses selectUser
}
}

It'll be used in ASP.NET layer like this: using BLL;

private void AddUser()
{
UserClass user = User.Select(id);
}

My question is, since static variables are not thread-safe, is this a bad design decision? I'm thinking of either implementing a locking mechanism, which makes me think if it'd slow down the application, or using instantiated class approach which makes me wonder if query compiling would be beneficial.
