public class NHibernateSessionPerRequest<T>:IHttpModule
{
public void Dispose() { }
public void Init(HttpApplication context)
{
context.BeginRequest += BeginRequest;
context.EndRequest += EndRequest;
}
}
How can it be registered in web.config?
What is the difference between HttpApplication class and IHttpModule? Are they both same or different?
I see articles that mention the same events in both the classes.
What is a Generic Class Declaration? and when should it be used?
View 2 RepliesASP.net C# 3.5 Framework, working in Visual Studio 2008 currently.
What I want is a Generic Data Access Class. I have seen several of them but what I want is to see one that I pass the Connection String and the SQL statement and it will return a List of Objects or when only one item an Object or when no response needed a boolean to let me know if it succeeded?
How can I create generic class from System.Web.Mvc.ViewPage?
View 1 RepliesI have several custom classes that derive from a common base class so they share several members in common. I would like to be able to pass objecs from any of these three classes to a function that will "look at" common properties. However, it seems there is a catch 22 -- When I try to access a member (.FirstName) of the passed object, the computer reports an error that it thinks the member doesn't exist.
It seems to be a sort of contradiction -- since I didn't declare the type, the computer can't confirm existence, but it seems that it should have to take it on faith since the generic character of the type is specified by the code. Possibly there is something I don't know about that would fix this. I'm showing VB code for what I have so far. I went ahead and hardcoded an instance to confirm that the object exists and has the needed property. I commented out the line that had the code that resulted in the computer reporting an error.

I want to bind grid using Bindlist(Generic class) and also ensure it does not have an impact on performance of the page.
View 2 RepliesI can have a base class for views in an MVC project like this:
public class BaseViewPage : System.Web.Mvc.ViewPage
{
public string Something { get; set; }
}
And then in the ASPX I can do this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage" %>
This works fine; the problem is when I try to do the same with the generic version:
public class BaseViewPage<TModel> : System.Web.Mvc.ViewPage<TModel> where TModel : class
{
public string Something { get; set; }
}
When I try to use this from the ASPX, like this:
<%@ Page Something="foo" Language="C#" Inherits="MyNamespace.BaseViewPage<SomeClass>" %>
I get the error message:
Error parsing attribute 'something': Type 'System.Web.Mvc.ViewPage' does not have a public property named 'something'.
Notice how it tries to use System.Web.Mvc.ViewPage rather than my BaseViewPage class. To make it more interesting, if I remove the "Something" attribute from the Page directive and put some code in the generic version of BaseViewPage (OnInit for example) the class is actually called / used / instantiated.
So, am I doing something wrong or is this a limitation.

All implementation of IHttpModule I've seen looks following:
[code]....
I am wondering why is the Dispose method always empty? Shouldn't we unsubscribe the event which we subscribe in the Init method?
I've declared an event on an HTTP Module so it will poll subscribers for a true/false value to determine if it should go ahead with its task of tweaking the HTTP Response. If only one subscriber answers true then it runs its logic.
Are there potential pitfalls I'm not seeing?
public class ResponseTweaker : IHttpModule {
// to be a list of subscribers
List<Func<HttpApplication, bool>> listRespondants = new List<Func<HttpApplication, bool>>();
// event that stores its subscribers in a collection
public event Func<HttpApplication, bool> RequestConfirmation {
[Code]....
An IHttpModule implementation I created
public class ResponseTweaker : IHttpModule { // my module ...
is registered in Web.config
<system.web>
<httpModules>
<add name="redman" type="ResponseTweaker"/>
</httpModules>
and an instance of it is sitting in the pipeline.
From the perspective of a caller (e.g. from the Global.asax.cs file), how should I get a reference to that module instance?
LoginPage.aspx:-
protected void Button1_Click(object sender, EventArgs e)
{
Context.Items["Username"] = txtUserId.Text;
Context.Items["Password"] = txtPassword.Text;
//
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1, Context.Items["Username"].ToString(), DateTime.Now, DateTime.Now.AddMinutes(10), true, "users", FormsAuthentication.FormsCookiePath);
// Encrypt the cookie using the machine key for secure transport
string hash = FormsAuthentication.Encrypt(ticket);
HttpCookie cookie = new HttpCookie(
FormsAuthentication.FormsCookieName, // Name of auth cookie
hash); // Hashed ticket
// Set the cookie's expiration time to the tickets expiration time
if (ticket.IsPersistent) cookie.Expires = ticket.Expiration;
Response.Cookies.Add(cookie);
Response.Redirect("Default.aspx");
}
Global.asax file:-
void Application_AuthenticateRequest(object sender, EventArgs e)
{
if (HttpContext.Current.User != null)
{
if (HttpContext.Current.User.Identity.IsAuthenticated)
{
if (HttpContext.Current.User.Identity is FormsIdentity)
{
FormsIdentity id =
(FormsIdentity)HttpContext.Current.User.Identity;
FormsAuthenticationTicket ticket = id.Ticket;
// Get the stored user-data, in this case, our roles
string userData = ticket.UserData;
string[] roles = userData.Split(',');
HttpContext.Current.User = new System.Security.Principal.GenericPrincipal(id, roles);
Response.Write(HttpContext.Current.User.Identity.Name);
Response.Redirect("Default.aspx");
}
}
}
}
I get the following error after signing in This webpage has a redirect loop.
The webpage at [URL] has resulted in too many redirects. Clearing your cookies for this site or allowing third-party cookies may fix the problem. If not, it is possibly a server configuration issue and not a problem with your computer.
Im trying to make a solution like this [URL] Now the question is how do I filter the request, I only want to Open an ISession if the request is for an ASPNET MVC Action, not for *.gif, *.css etc. How should I handle this filtering?
View 3 RepliesI'm trying to create a control out of a class I found, and one of the overridden functions is the following:
protected override void PerformDataBinding(IEnumerable data)
However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.
What is the difference between generic and non-generic collection?
View 1 RepliesI am getting the following error
'Event handlers can only be bound to HttpApplication events during IHttpModule initialization.' at the following code (line in bold or double **)
protected void Application_BeginRequest(object sender, EventArgs e)

HttpApplication app = (HttpApplication)sender;

}
protected void Application_EndRequest(object sender, EventArgs e)

which is mentioned in Global.asax file.
In ASP.NET 4.0, I have an IHttpModule that apply a filter on HttpRequest.Filter. As the result, the content stream length is changed, and it breaks WCF with now returns 400 bad request because of the mismatch between the body length and the HTTP headers.
View 1 RepliesI've created a simple sample site to demonstrate the issue. In it, I have a Default.aspx Page that has a button on it:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p><asp:Button OnClick="ButtonClick" Text="Button" runat="server" />
</p>
<asp:Label ID="output" runat="server" />
</asp:Content>
The code behind just sets the label text on the button click:
protected void ButtonClick(object sender, EventArgs e)
{
output.Text = "Button Click!!";
}
I then have an IHttpModule that gets called for every request:
[code].....
And now it's broken again! So to make a long story short, just by accessing the Form collection on the request in the IHttpModule, I somehow screw up the PostBack, and the event never gets fired.
I have a website that has a secure admin section with its own login page and a public area with another section that allows people to register and login (using a different login / register page). In my web.config file I have this entry <location path="MemberDetails.aspx">
View 11 RepliesI'm running VS 2008 and .NET 3.5 SP1.
I want to implement hit tracking in an HttpModule in my ASP.NET app. Pretty simple, I thought. However, the BeginRequest event of my HttpModule is firing twice for each page hit. The site is very simple right now...no security, just a bit of database work. Should log one row per page hit. Why is this event firing twice?
Moreover, IHttpModule.BeginRequest actually fires a different number of times for the first page hit when running for the first time (from a closed web browser)...3 times when I'm hitting the DB to provide dynamic data for the page, and only 1 time for pages where the DB isn't hit. It fires 2 times for every page hit after the first one, regardless of whether or not I'm touching the DB.
It's interesting to note that Application_BeginRequest (in Global.asax) is always firing only once.
i see in many pages that in the register is created a string that must be rewrited in a textbox and in the click of confirm they are compared if they are the same to procceed
