C# - Why Do We Need Http Handlers

Jan 5, 2011

I understand that the http handlers process request but this is just theory as I don't understand it. Many 3rd party controls require adding a http handler in web.config. And sometimes we are required to create our own class with ProcessRequest method that implements IHttpHandler interface but I am confused to understand where Http handler fits in and what their roles are?

Any Tools To See Which Http Handlers Are Called?

Feb 24, 2011

I am trying to get a captcha web control to display, but it isn't going into the HttpHandler that I created. This isn't my project and it is quite big so I'm not sure what is going on. Is there any tools or techniques to see which handler is being called.

C# - Programmatically Set HTTP Handlers In .NET Application?

Nov 4, 2010

I need to dynamically instantiate a web application from a console application. By this definition, I mean that my console application contains a web application that is not bound to IIS/XSP.Currently, I create the web application into a temporary directory and copy some forged files into it. These are a special Global.asax that maps to my own implementation of HttpApplication to use in the web application (I need to do some initialization at app start), then I forge special .asmx files that map to my own skeleton classes and dynamic plugins

foreach (IPlugin plugin in _target.Plugins)
{
WsdlSkeletonDefinition[] defs = plugin.GetWsdlSkeletons();

My approach works, but I'm not so satisfied by it because I have to write lots of garbage into file system, even if I eventually delete it all.I know I can control HTTP handlers via Web.config, but I don't want to forge a Web.config for that. I would like to create a mapping such as I can remove the .asmx extension from web services' URLs and still get them.For example, one of the default scripts is "LogbusManagement.asmx", which must be hard-coded into client APIs and the .asmx prevents portability to other platforms such as PHP. I want to make "LogbusManagement.asmx" equivalent to "LogbusManagement" and any extension. For this, I might use an HttpHandlerFactory.

My straight question is,like asked here by somebody else: is there a way to programmatically, possibly from Global.asax, to set IHttpHandlers or IHttpHandlerFactories for web applications?

HttpHandlers / Modules :: Trying To Get A Handle On Http Handlers?

May 27, 2010

I have created a dynamic signature for our members in Asp.net 2.0 with VB code behind that they can use as a signature in various message boards using an http handler.This is the first time I have evered used a http handler and I am probably missing a step on how to use it.The direct url to the signature is:
[URL]where the ID is a particular member. This works fine on most message boards and if you copy the link directly in a browser window, but not in other message boards.In order for this signature to work on all message boards, the url syntax would need to be as follows:[URL] or something similar where the URL does not have question marks, equal signs and the file name ends in .png .How can I go about doing this where the link will go to my http handler and overlay text, etc.

What Is Difference Between Web.config Assemblies Element And Project File Reference Element

Sep 29, 2010

I'm looking at an asp.net application, i notice that there are assemblies defined into two places. In web.config there is configuration/system.web/compilation/assemblies/add elements. In the project file there are references setup under the Project/ItemGroup/Reference elements.

I was wondering, what is the difference between assemblies/references added in either location?

AJAX :: Element 'ToolkitScriptManager' Is Not A Known Element - For Network Drive Websites

Feb 2, 2011

I have noticed that when I create a website in a network drive and use the Ajax toolkit I get :

Element 'ToolkitScriptManager' is not a known element

I also noticed that after adding the ToolkitScriptManager it doesn't add the ID in the source code, it looks like this:

<asp:ToolkitScriptManager runat="server"></asp:ToolkisScriptManager>

Is missing the ID="ToolkitScriptManager1" part.

This doesn't happen when I create the site in my local drive. Is there a workaround to this. Even if I add the missing parts, I keep getting the same error.

Why Doesn't The Rendered <div> Element Act Like A Normal Block Element

Aug 22, 2010

You're making a website with ASP.NET 4.0/C#, although xml alone is suitable for this example. The site will have a site map and a default page with a menu control, as follows:Web.sitemap

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="~/default.aspx" title="Home" description="">
<siteMapNode url="~/1.aspx" title="Link 1" description="" />
<siteMapNode url="~/2.aspx" title="Link 2" description="" />
<siteMapNode url="~/3.aspx" title="Link 3" description="" />

Element 'Chart' Is Not A Known Element - DotnetCHARTING?

May 9, 2010

I am using dotnetCHARTING: the dll is installed in the GAC and referenced in my web.config (all versions appear to match). The project has a reference to the dll.

web.config:

<add assembly="dotnetCHARTING, Version=5.3.3540.17054, Culture=neutral, PublicKeyToken=af2cd47db69d93bd"/>

The site code compiles ok, but all aspx pages using the charting library complain that the Chart tag does not exist (warning that it might be a compile error). The aspx pages do not render the charts.

Each page has a reference to the assembly:

<%@ Register Assembly="dotnetCHARTING" Namespace="dotnetCHARTING" TagPrefix="dotnetCHARTING" %>
