I want to create an HTTP handler within my project. To do this, I created a new class, and tried to implement IHttpHandler.
Each time I do this, I get the error 'End of statement expected'.
I know that normally you can create a new class library and create a class to implement a handler. But why is it not possible to do this in an existing web project?
I'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.
View 8 RepliesI'm trying create unit testing for an existing website project (not web application project). I cannot access my under test classes unless I use accessor. However, if I use accessor, I have problem to initiate an object with passing arguments. I only want to create unit tetsing for App_Code. After searching web, and I found that I'd better to create a web application project using my current existing website project. From solution explorer, add new project ->using existing website. My questions is: what impact will have for my current website to create the new project? Should I just convert my current website to web application? If do that, will it cuase problems on my website? I am new on asp.net, still learning..
View 1 RepliesI have created a Custom 404 handler. This page is handled successfully when a URL includes a page (http://mysite.com/baddirectory/mypage.aspx) however when it does not include a page (http://mysite.com/baddirectory/) the custom page does get called and I am presented with a typical 404 message

For the purpose, I want to put my logic for creating the rss XML in C# class, which implement IHttpHandler, then to "map" this handler into the web.config file and to register the "mapped name" in my routing rules. I am doing something like this:
public class RSSFeedHandler:IHttpHandler

I got an ashx file to create an image. I am referencing it via web.config like this:

My handler looks like that:

Actually the handler never gets called. I already searched the forums and tried some tips and hints. But nothing of that worked. Try to call the url via[URL]
As im new to this concept,i request anyone to explain in detail about configuring the custom handlers in IIS 5.1 STEP by STEP and also about mapping the extension.
View 1 RepliesI made a custom handler that derives from MvcHandler. I have my routes using a custom RouteHandler that returns my new handler for GetHttpHandler(), and I override ProcessRequest() in my custom handler. The call to GetHttpHandler is triggering a breakpoint and my handler's constructor is definitely being called, but BeginProcessRequest() is being called on the base MvcHandler instead of ProcessRequest().
Why are the async methods being called when I haven't done anything to call them? I don't want asynchronous handling, and I certainly didn't do anything explicit to get it. My controllers all derive from Controller, not AsyncController.
I don't have the source code with me right now, but I can add it later if needed. I was hoping someone might know some of the reasons why BeginProcessRequest might be called when it's not wanted.
I have an IHttpHandler that I would like to hook into the OutputCache support so I can offload cached data to the IIS kernel. I know MVC must do this somehow, I found this in OutputCacheAttribute:
public override void OnResultExecuting(ResultExecutingContext filterContext) {
if (filterContext == null) {
throw new ArgumentNullException("filterContext");
}

This is a weird issue. I have a List view with 2 Link buttons. "Edit" and "Delete" Iam able to attach an event handler for the first linkbutton(Update). Code in the event handler executed fine. But If I try to attach a event handler for the second link button(Delete) , I get an error.
My Item Template Looks like this.
[Code]....
First Item works absolutely fine. But If I attach the second handler, I get the following error
Am I missing some thing ? Note - There is no error if I try to attach the 1st event handler to the second link button.[ie EditLinkButtonClicked to DeleteLinkButtonClicked ] Issue occurs only when I try to attach DeleteLinkButtonClicked to DeleteLinkButton
I'm using Microsoft's PivotViewer control in one of my Silverlight projects. I'm creating a JIT collection and was hoping to dynamically generate the images based on the rendered result of a WPF UserControl. In order to generate the images I'm using an HTTP Handler to serve the images up dynamically.
how I might best go about this. It's all quite a mashup of technologies and a bit difficult to know where best to begin.
EDIT: I have found a guy that's done this in ASP.Net MVC here -
I am trying to add page with custom extension, say .asp2 with my set of html tags.Now whenever i try to access the page on browser...it asks me "Save as". This happens because I am using an extn which the server is not able to recognise.What should I do to so that my server, IIS 5.1 recognises this extension??
how to associate custom events on such custom page?
I am trying to implement an IHttpHandler. I have defined an appropriate class but the debug web server (you know, the one you get if you hit f5 in Visual Studio) is responding with "Can't Display Page".I looked here http://msdn.microsoft.com/en-us/library/ms228090%28v=VS.90%29.aspx to learn how to configure the handler, and it seems there are different ways for IIS6 and 7. But the process is put something in the web.config and then set it up in IIS Manager. However, that is a deployment issue. I want to be able to run it in the test server, and I don't know how to do this second step in the test server.I put the following in my web.config:
<httpHandlers>
<add verb="*" path="*.sample"
type="MyNamespace.Code.HelloWorldHandler"/>
</httpHandlers>
HelloWorldHandler is the code from the link above (wrapped in MyNamespace.)
Can someone let me know how to configure this correctly for the development server?
I'm working on a reporting script which runs a number of reports (pdf) on button click. The reports are created on the web server then I'd like the user to be given the option to download the files. I have worked out the script for downloading one file from the server. But I'm not sure how to download multiple files? (there will probably be about 50)
After I run one report I redirect the user to a http handler script.
Response.Redirect("Download.ashx?ReportName=" + "WeeklySummary.pdf");
public class Download : IHttpHandler {
public void ProcessRequest(HttpContext context)

I have a IHttpHandler that acts as a source to a jQuery Autocomplete input field. In the constructor of the handler I generate an index that remains fairly static between request (needs to be rebuilt maybe once a day).How can I cache the the index between calls? Debugging indicates that the constructor is called for each request. I've set IsReusable to "false".
View 2 RepliesI have an IHttpHandler that implements IRequiresSessionState. Everything works fine on most servers but there are 2 servers (one IIS 7.0 and one IIS 7.5) that give me null sessions. Aspx pages are fine on every server. I've searched for hours and failed to find anything that is not related to IRequiresSessionState.

First, I'm looking for a a small example of how to handle a series of RESTful URLs, such as /Account/{userName} and /Account/{userName}/Profile with a single HttpHandler. At this time, I'm not interested in embracing MVC or using the REST Starter Kit. Should I place the HttpHandler class in a Class Library? Should I publish to the root of the RESTful URL?
My second issue stems from the fact that my ASP.NET hosting is done through a web-hosting company. Will I need to ask their tech team to configure IIS for me? Is that normal practice?
I want to implement a restful service in ASP.NET. I want it to be compatible with .Net 2.0 and IIS 5+. I am constrained to not use ASP.NET MVC or REST starter kit. By reading on internet I have learned that it can be implemented using HTTPHandlers. The problem is, the request will come in as a POST request. And I want to URL to be like:
http://abc.com/MyService/MyMethod1/
and
http://abc.com/MyService/MyMethod2/
I create custom HTTP handler for auto generating file and I want to tell IIS7 to serve current request like normal static file because I need to use IIS and web.config file to control compression setting and any other HTTP header of current requested file.I know. there is an internal class called StaticFileHandler in ASP.net. But I cannot access it. Or you have any other way to work like this.

I created an application and implemented IHTTPHandler for all incoming request ending with ".aspx" extension.Under "ProcessRequest" module, I am creating an instance of HttpContext (with URL attributes different from my application's URL i.e. if I am working on localhost then speciying Yahoo.com as its URL) and assigning it to "context" which comes as method argument.After redirection, an error is generated. Also, the custom HTTPContext is not passed to the requested page (default.aspx, in my case.)Code is as follows.
