I haven't used the application variables in my asp.net web applications. Im using asp.net2.0. Is there any disadvantages of using applicationvariables.

View 2 RepliesWhen do you need IIS Web Garden feature. What's pro's and con's?
View 2 RepliesWe have an application that has quite an extensive APP_Code directory (about 150 functions). The functions are split across multiple files and then classes and namespaces.
On numerous pages we have to create numerous instances of the classes to be able to access the functionality, which can get very repetitive and means we're repeating code on every page declaring the instance etc.
As far as I can tell, a way to navigate this issue, is to make the functions Public Shared (as opposed to just Public functions).
I am searching for the advantages and disadvantages of the explicit interface implementation

View 3 RepliesIf I declare a static field in a type instantiated within an ASP.NET application, hosted within IIS, is the same variable (i.e. same memory location) used by all of the worker threads used by IIS, opening up concurrency issues?
View 1 RepliesI'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.
I have two different IIS applications within the same domain(let us say www.mydomain.com) , both of these applications use the same database instance(same connectionstring), now what I want is that both of applications can see each sessions variables , can SQL Server session state mode helps in this case? Did someone try that before? Is there any other way to share the session variables?
View 3 RepliesI am developing a web application for mortgage business related data (not mortgage calculation)in C#.( My job is to convert a classic asp app ..so workflow is already there. )Suggest sample application from where i can read and follow structure . It should have tabbed panes, user creation with different level of rights, complex web forms taking lots of input and using ajax.(even a bit of LINQ....as demanded by management!!) I found Nopcommerce interface very good. something similar but smaller in size. My ASP.net webforms knowledge is beginner to intermediate level.
View 1 RepliesI have a very huge Asp.Net application using Asp.net 3.5 with aournd 3000 pages. Now we need to integrate some Silverlight controls in it. For e.g we need to change the dashborad to incorporate new SL UX. My question is that easy to use these 2 technologies i.e. Asp.Net and SL and both have different projects. Will that be difficult for us to communicate with each of these web applications and SL Application. We are in the middle of making a decision as to how to integrate SL in our exisiting application.
Keep in mind that its out of the question that we can shift the whole application to SL. We must have to stick to asp.net 3.5 or 4

It say Application is not a known object and I can't for the life of me figure what to do a "using" on to expose it. I am in a static class at the time I cant use it. It seems to work in other units?

View 1 RepliesI have one website over at utopiapimp.com. The website is used for a popular web based game. Some company internets don't allow the website to be accessed so I opened up another domain at utopiashrimp.com. Same website but a different iss application. Both have same database backends. They also both sit on the same virtual machine. I put my brand new code on shrimp and solve bugs with that code. I host the solid code on pimp. So I can't just forward the shrimp domain to pimp because I need a test bed.
The problem is that they don't share the same application cache. So my question is, can two websites share the same application cache? I really need to figure this out. I would rather not create a webservice and or a handler that one website needs to hit to change the cache on the other application.
This question actually refers to a classic ASP page I'm working on, but I'm assuming that app variables work the same in both ASP and ASP.NET Let's say we have a bunch of websites, owned by different people. The sites are all different, but the common theme is they are car enthusiast websites. Each of these websites has their own unique index page (of course), but also "common" pages, which are pages shared by all the websites.
One of the common pages, checks for the value of an application variable, which may or may not exist. For example, lets call this page luxurycars.asp, which is a simple page that shows the top 10 luxury cars of this year. This common luxury car page will pull and use the app variable like so:
[CODE]
Dim SiteOwner
SiteOwner = Application("OwnerName")
Response.Write("This site is managed by " & SiteOwner)
[/CODE]
This app variable is set uniquely in each clients index.asp page like so:
[CODE]
Application("OwnerName") = "John Doe"
[/CODE]
Will this work? I just started learning classic ASP (for my job), and I'm reading that application variables are universal and only one copy of the variable will exist. So does this mean if John Doe sets Application("OwnerName") to "John Doe" in HIS index.asp page, will everyone that visits the common luxury car page see John Doe's name? Regardless of whether they got to that page via John Doe's page or someone elses? And if so would using a Session variable instead solve this problem? Sorry if this sounds confusing, let me know if I need to re-word it or give more detail...
I store a large structure holding my application's reference data in a variable I access through HttpContext.Application. Every once in a while this data needs to change. When I update it in place, is there a danger that incoming requests will see the data in an inconsistent state? Is there a need (and a way) to lock some or all of this structure? Finally, are there other approaches to this problem other than querying the database every time you need this (mostly static) data?

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:

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.
