  Cannot call to handler.ashx in Vista IIS7

  May 09, 2009 02:42 PM|LINK

  I just moved to Vista with IIS7 from XP (IIS 6). Now, everything works fine except the handler is not working and it will throw a Visual Studio Just In Time debugger out.

   The handler is just a simple image handler, which takes in an ID and then find in database and then return as content type of image.

  Is there something I am missing?

  Try adding your ashx handler to the list of managed handlers in IIS Manager. See the example here.

  I dont know why it's not working.

  This is my handler:

  namespace CoreApp

  {

             public class WebPreviewHandler : IHttpHandler

                  {

   

  and then in web.config i have:

  <handlers>

  <remove name="WebServiceHandlerFactory-Integrated" />

  <remove name="ScriptHandlerFactory" />

  <remove name="ScriptHandlerFactoryAppServices" />

  <remove name="ScriptResource" />

  <add name="WebPreviewHandler" verb="*" path="*.ashx" type="CoreApp.WebPreviewHandler,CoreApp.dll" />

  <add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

  <add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

  <add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />

  </handlers>

  When I run the handler directly, it says:

  Could not load file or assembly 'CoreApp.dll' or one of its dependencies. The system cannot find the file specified

  I dont know why it's not working.

  Try these:

  <httpHandlers>

  <add verb="*" path="*.ashx" validate="false" type="CoreApp.WebPreviewHandler, CoreApp" />

  </httpHandlers>

  <handlers>

  <add name="WebPreviewHandler" verb="*" path="*.ashx" type="CoreApp.WebPreviewHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode" />

  </handlers>

  
  

  It's not an ASP.NET MVC application, is it?

        "ScriptHandlerFactoryAppServices">
        "ScriptResource">
        "WebPreviewHandler" verb="*" path="*.ashx" type="CoreApp.WebPreviewHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode">
  
  
         "ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
        "ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
