public class CacheHelper { /// <summary> /// Removes object with the specified key. /// </summary> /// <param name="key">The key.</param> [code]....
I have this methods for caching..I need to change this methods to use in aDictionary<string,object>
How do I need to change this code Because I am new to asp.net I am still learning..
I have an extension method as follows:
public static class PageExtensions
{
public static int GetUserId(this Page targetPage)
{
var user = Membership.GetUser(targetPage.User.Identity.Name);
return (int)user.ProviderUserKey;
}
}
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId()
{
return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey;
}
and I call it as follows in my WebMethod: PageExtensions.GetUserId()
I have a class that maintains a static dictionary of cached lookup results from my domain controller - users' given names and e-mails.My code looks something like:
private static Dictionary<string, string> emailCache = new Dictionary<string, string>();
protected string GetUserEmail(string accountName)
{
if (emailCache.ContainsKey(accountName))
{
return(emailCache[accountName]);
}
lock(/* something */)
{
if (emailCache.ContainsKey(accountName))

We say that "GroupBy" and "OrderBy" methods from LINQ as Extension Methods.Then how about "variable.ToString()" and "string.Split()" menthods. Are these Extension methods.
View 2 RepliesHow to use extension methods and customizes generic list collections??
View 1 RepliesI'm searching for some extension methods that helps programming in ASP.NET. Some functions to work on controls, validators, AJAX or programing in C# in general.It could be methods library or your own methods.Do you know any source of those methods (other than CodePlex - that is good source of generic extensions) especially for ASP.NET?
View 1 RepliesNote , that i'm new to c# so it might not be a problem.first , what is the exact meaning of @ in Razor ?does it mean WebPage.Response.Write ?next, i designed an extension method to WebPage ( by the way that is the coolest feature ever in c# )in my Razor code , to use it in a webpage , i must write @this.MyExtensionMethod() instead of @MyExtensionMethod().So why is it? because @this.MyExtensionMethod() and @MyExtensionMethod() should be the same ?
here is my extension method :

With regards to the Razor view engine, say I want to render Html.TextBoxFor<SomeModel>(i => i.Name), it doesn't seem that the inline syntax works as in:
@Html.TextBoxFor<SomeModel>(i => i.Name)
This doesn't seem to work because it interprets the generic as an HTML tag. I could use a code-block approach, but then what's the best approach to output the content? The HTML string returned from this method, do I response.write it, or is there a syntax for it, or what's the approach?
I am trying to create an extension to extend the HtmlTextbox methods to allow our developers to add onkeydown inline javascript to auto click a button with a name they specify.

I have a web site project using the .NET 2.0 Framework that I am working on in Visual Studio 2008. I am using a third-party DLL in my project. I have added a reference to the DLL in my project and I can use everything as expected, including a number of extension methods for certain objects. Intellisense sees these extension methods, and I am able to make use of them and I can build my project on my local machine without any errors.
However, when running my website on a production server, I get a Compilation Error saying that the extension method I am trying to use could not be found. I can use everything else in the DLL besides the extension methods on the production server.
This is my first exposure to extension methods and understand what they are, but I can't seem to figure out why I can't make use of these methods outside of my local machine.

I'm using IOC containers that wrap items of HttpContext, such as Request and Session variables, to simplify mocking of it for testability.
Since IsAjaxRequest() is an extension method, it doesn't show up in HttpContext.Current.Request.
Is it possible to wrap extension methods with a IOC container? How?
In the previous version of our application we worked one we used MVC 1, so no area's. Following the ASP.NET MVC Best Practices by Kazi Manhur, I Created Extension methods of UrlHelper to generate your url from Route
Now with the new version, we are using MVC 2 and Areas. I was just wondering if one should implement it as before or have a new "best practice" regarding this emerged?
What I'm doing right now is:
1) Create a route in my area's route registration:
[Code]....
2) Creat an UrlHelper Extension method:
[Code]....
3) then just call it like this:
[Code]....
While typing this I started wondering what is the use of the ID you specify for the Area route..cant one just call the route using that?
Is it possible to do something like this inline in an ASPX page?
<%= Me.SomeExtensionMethod() %>
I can't seem to figure out how to get this to work properly. I'm receiving an error saying that "SomeExtensionMethod" is not a member of the current Page object. I've added the necessary <%@ Import Namespace="..." %> directive at the top of my page. This Does work in code-behind.This isn't vitally important, but it would be good to know how to do in the future.
namespace MvcLogin_Validation.Helpers

I am beginner in web applications development. I started one little project and host it on source forge "https://homoco.svn.sourceforge.net/svnroot/homoco". And I started implementing authentication in this application to learn how it works. From my experience people never use out of the box things so I want to implement this stuff alone (like in real world projects). So some questions:
1) Is there any reason to use membership out of the box? To use database table schema, stored procedures etc. that tool generate for developer. I think that this lower control over code and I decided to implement it my self. I don't know if I am right.
2) Is my approach in this demo project good or bad (if someone have time I like to do just a little code review)? I created database based on business rules. Not using database schema that membership provider require. Extend "MembershipProvider" class to satisfy my needs. Implement queries to database myself.
3) Now, this question is a little wired but I have to ask it. If we make custom Membership Provider and do sql queries alone, implement all MembershipProvider class methods ourselves, and in application use Membership.blabla() why is this approach different from not extending MembershipProvider class and putting all this methods in some unique class and call its methods then? I hope that someone understand what I ask here.
I am sorry for three questions, but I really trying to find the best way to implement this feature in my demo project like it is a real world application.
I have set up the membership provider on my own database and can create people fine.I wanted to be able to add more attributes than what the method is offering me.w I would change the method to accept more? Where is it?
View 3 RepliesI've written the following Extension Method
<Extension()>
Public Function ToUtcIso8601(ByVal dt As Date) As String
Return String.Format("{0:s}Z", dt)
End Function
But I also need a Nullable version of the same method... how exactly do I do this?
This is what I was thinking, but I'm not sure if this is the right way

i have a repository class inside my model folder; this repositiry contains many methods , which are called from Action methods in the controllers; so my question is :- if i have a method insidle my model.reporsitory which calls a stored procedure, then can i call it an "action method"? or "action method" expression only apply to controller methods?
View 4 RepliesWe are developing a web app that will have a pretty complex user and permission system. The general idea is that we have 3 levels of security:
a simple user - that can only access basic data that is in a data repository
a manager - that can open up data repositories
a superuser - that can open up repository factories.
Each repository contains various data types(text, images, etc etc). We are looking for authentication methods that will allow us:
1. Scalability.
2. Customization.
3. To create permissions that will effect the GUI + deny access to certain pages.
4. To create predefined roles - that will allow for easy setup of new users.
5. To create custom roles for specific users - allowing them permission sets that are different from the predefined roles.
I Wrote code to copy Client side DB to Server side by providing the credentials required. I have a simple form, Containing three textboxes and submit button. the textboxes takes UserId,Passwd and Servername of ORACLE(Client Machine's) and when user press submit button. the VB Script method invoked. here the function follows.

server = form.Connect.Value
Dim strcon
strcon = "Data Source=" + server + "; User ID = " + usr + ";Password=" + pwd + ";"
con.open strcon
dim rs,str
str = "select * from emp"
set rs= con.Execute(str)
if rs is not nothing then
PageMethods.SendForm(rs)
