- Httphandler: Could Not Load Type 'Upload'

Feb 4, 2011

I'm still trying to follow this sample:

http://www.codeproject.com/KB/aspnet/FlashUpload.aspx

Under Visual Studio it's working fine but, when I try to publish on IIS it doesn't works. This is the situation: under my Website I created a Upload.vb class under App_Code folder that implements IHttpHandler, IRequiresSessionState.

On web.xml I wrote this rows:

<remove verb="POST,GET" path="Upload.axd"/>
<add verb="POST,GET" path="Upload.axd" type="Upload"/>

On Page.aspx I added this code:

<FlashUpload:FlashUpload ID="flashUpload" runat="server"
UploadPage="Upload.axd"
FileTypeDescription="Images" FileTypes="*.doc; *.xls; *.pdf; *.docx; *.xlsx"
UploadFileSizeLimit="0" TotalUploadSizeLimit="0" />

I followed the sample and my class has not namespace. I read on internet that this error happens when IIS is not able to find the class.

Could Not Load Type 'System.ServiceModel.Activation.HttpHandler' Version Conflict With WCF REST

Jan 6, 2011

I've run into a problem with WCF REST Service. I get:

Could not load type 'System.ServiceModel.Activation.HttpHandler' from assembly 'System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

when running inside of the IIS in an ASP.NET 4.0 AppPool.

The problem seems to occur only if:Running inside of IIS
When ASP.NET Comaptibility is enabled

Running in Cassini - no problem it works properly. Running with ASP.NET compatibility off - no problem it works.

It appears that it's some sort of handler version conflict trying to instantiate the wrong version of the handler that in turn tries to load an older version of System.ServiceModel, but I haven't been able to trace this down.

Anybody seen anything like this before and have any ideas how to track this down further?

I've looked in ApplicationHost.config and the master web.config files for System.ServiceModel and HttpHandler references but no luck.

Could Not Load Type Error

Jan 13, 2013

I keep getting the above error whether I ran my asp.net solution from the IDE or publish it on IIS. I always Build before each one of these steps.

I have user controls inside web pages and have 4 different projects that each reside in its own folder.

I have a login page and main user page that are one project then the user on this main page can go to 4 different areas which are all separate projects in their own folders. Links on this page to these sections are as follows:

./MyYFolder/MyYMain.aspx

If user clicks they get the error. Bizarrely if I locate the page MyYMain.aspx in the root folder and change the path in that main page to:

./MyYMain.aspx

As a bright spark noted, my problem isn't that I'm getting no error under the 2nd scenario. My problem is that I'm getting an error under the 1st one.

I have started a new MVC application (I am new to MVC and ASP.net in general) I am trying to write a custom provider class that overrides the MembershipProvider class.

The project compiles fine. In the web.config file, I have added the following line:

When I try to register a user, I get the error message:

C# - Load User Control Given Its Type?

Mar 5, 2011

Is there a way to instantiate and use a usercontrol (.ascx) if given you have its Type (ie. typeof(MyUserControl))?With regular asp.net controls like a textbox or a dropdownlist you can just make a new instance and add it to a controls collection. This doesnt appear to work for User controls. While you can make a new instance and add it to a collection, and have all of its events fire, it will not actually render to the page. Typically you would call Page.LoadControl() with the path to the .ascxThis presents a problem if all you have is its type. How can you get the path to the .ascx to give to the LoadControl method. Ideally I would also like to not have to have a reference to the Page object

MVC :: Could Not Load Type While Running VS2010 Project

May 23, 2010

I have had a project called Articles and the project complies fine. I have it running as a seperate site on my machine and it works like a charm under IIS7. When I start the project from VS2010 in debug mode (by pressing F5) it lands on a page that says: "Parser Error Message: Could not load type 'Articles._Default'."

I i however change the path in the browser from [URL] Home it works fine again, indicating that my routing table is bust but it was working yesterday and I did not change any route, The error page also says: "Please do not delete this file. It is used to ensure that ASP.NET MVC is activated by IIS when a user makes a "/" request to the server." That idicates to me that it went to default.aspx...right?

Also this is a barebones application, basically the default project structure published for testing purposes.Any suggestions as to resolving this?

C# - Load A Type In Parent-child Website?

May 22, 2010

I am developing a C# VS 2008 / SQL Server 2008 website. Although this same code compiles in the Project version, the website version does not compile. Many of their files are the same so I do not understand even where to look. The only compile error I get is:

Could not load type 'DataMatch'

in my DataMatch.aspx file. Is the problem in my web.config file? How do websites differ from projects in VS? All four of these files reside in same directory.

Default.aspx file:

<%@ Page Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Default.aspx.cs"
Inherits="AddFileToSQL" Title="Untitled Page" %>

Default.aspx.cs file:

using System.Data.SqlClient;
using System.Security.Principal;

namespace AddFileToSQL
{
public partial class AddFileToSQL : System.Web.UI.Page
{
...

DataMatch.aspx file:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="DataMatch.aspx.cs"
Inherits="DataMatch" %>

.net - System.Web.HttpException Could Not Load Type '[namespace]?

Feb 7, 2011

This started as Could not load type 'Global' error. After I tried a few things and getting no where I deleted the Global.asax file and now the error is Could not load type '[namespace].???'Where ??? is the class name of every page I try to load.The web site (when executed within VS2008, local dev computer) works fine but once published (with no errors) and deployed to the server gives me Could not load type '[namespace].???' error

I did install elmah and I was able to get more details for this "generic" Could not load type '[namespace].???' error

elmah reports a HTTP error 500 :

System.Web.HttpException Could not load type '[namespace].???' ->
System.Web.HttpParseException: Could not load type '[namespace].???'

I have checked the "basics"

References
Doing a clean and a build Checking the Inherits attr in the HTML against the code behind

UPDATE #1 I did deploy the site to a different DEV computer (configured IIS, virtual folder, etc.) and it works. When I use the same published code on the server, get the generic Could not load type '[namespace].???' error

UPDATE #2 I created a test web app. One form (Default.aspx) with a button. The click event does a Response.Write("Hello World"); I moved this app to the server and guess what, I get the Could not load type TestSite._Default

UPDATE #3 According to the fusion log viewer, these two websites are attempting to load CppCodeProvider and VJSharpCodeProvider, but I have no references to any of these. After a Google search, I found this post.I checked and I have no references to JAVA files.

Could Not Load Type 'MapProvider' From Assembly During .Net Unit Test

I'm receiving a System.Configuration.ConfigurationErrorsException with the message Could not load type 'XxxSiteMapProvider' from assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

I'm trying to unit test a separate class in the the same project as the XxxSiteMapProvider custom class. The error message indicates the proper point of the App.config for picking up the custom SiteMapProvider and I did a search across the solution and the class name is not duplicated anywhere. (I saw from searches that conflicting class names may cause this error.)
