Starting threads in HttpModule

Posted By:      Posted Date: September 28, 2010    Points: 0   Category :ASP.Net

Hi, I'm facing strange problem. I tried to start thread on HttpModule level, it works well on IIS7, but on IIS6 thread just won't start. I tried everything (configuring app pool, chaning machin.config) but nothing helped. 

Code is something like this

    public class MyModule : IHttpModule
        public void Init(HttpApplication context)
            context.PreRequestHandlerExecute += new EventHandler(call);

        public void call(object sender, EventArgs e)
            log("Starting threads");
            Timer t = new Timer((a) => log("From timer"), null, 1, 100);
            ThreadPool.QueueUserWorkItem((a) => log("From thread pool"));
            new Thread(() => log("From thread")).Start();

This sharpoint 2010 problem solving threads

Hi friend,

you can use this thread to solving problem and solutions.

Multiple Paramatized Threads



I have a  method that calls two subsequent methods that contain multiple parameters. I would like to run these methods simultaneously and then preform an action based on the return of both methods, so The parent thread cannot continue until BOTH threads have completed. I have tried going trough MSDN examples and haven't got anything to work (the issue is that the parent thread (aka the main method) continues on once one of the thread completes). I have tried cheking the state of threads and waiting the threads, but have not gotten anywhere. Any help would be great. Thanks.

Facebook like Profile URL with HttpModule


I am trying to make URLs for users profile pages like Facebooks e.g. http://site.com/username. I had a code snippett from a book for how to do this but when it runs it says its processing a request that will never finish. Im new with HttpModules/handlers but Ive looked over like 100 pages trying to figure this out. My code is below. Any help figuring this out would be greatly appreciated..

public class URLRouter : IHttpModule
/// <summary>
/// You will need to configure this module in the web.config file of your
/// web and register it with IIS before being able to use it. For more information
/// see the following link: http://go.microsoft.com/?linkid=8101007
/// </summary>
#region IHttpModule Members
private IUserRepository _userRepository;

public URLRouter()
_userRepository = ObjectFactory.GetInstance<IUserRepository>();

public void Dispose()
//clean-up code here.

public void Init(HttpApplication context)
context.PostResolveRequestCache += (new EventHandler(this.Application_OnAfterProcess));

Open PopUp Window From Error httpModule


I would like to open a popup window from the assembly to present the information to the user. Does anyone know if this is possible, I am presently doing the following:

        WriteLine("body {font-family:""Verdana"";font-weight:normal;font-size: .7em;color:black; background-color:white;}")
        WriteLine("b {font-family:""Verdana"";font-weight:bold;color:black;margin-top: -5px}")
        WriteLine("H1 { font-family:""Verdana"";font-weight:normal;font-size:18pt;color:red }")
        WriteLine("H2 { font-family:""Verdana"";font-weight:normal;font-size:14pt;color:maroon }")
        WriteLine("pre {font-family:""Lucida Console"";font-size: .9em}")

ASP.NET Pipeline: Use Threads and Build Asynchronous Handlers in Your Server-Side Web Code


Fortunately for developers, threading in ASP.NET is a lot easier than it was in ASP. In this article, the author takes a look at threading in the ASP.NET HTTP pipeline, and explains how threads are managed efficiently without the involvement of the developer. The article considers how the common language runtime threadpool is used by ASP.NET to service requests, looks at the pooling mechanisms used for handlers, modules, and applications, and covers both IIS 5.0 and IIS 6.0 and how they differ in their approach to request processing and thread allocation. Finally, how and when to use asynchronous handlers is discussed for developers who still need to use threads in their own applications.

Windows Forms: Give Your .NET-based Application a Fast and Responsive UI with Multiple Threads


If your application performs any non-UI processing on the thread that controls the user interface, it may make the app seem slow and sluggish, frustrating users. But writing multithreaded apps for Windows has long been restricted to C++ developers. Now with the .NET Framework, you can take advantage of multiple threads in C# to control the flow of instructions in your programs and isolate the UI thread for a fast and snappy user interface. This article shows you how. Also, it discusses the pitfalls of multiple threads and presents a framework for safe concurrent thread execution.

Installing a httpModule on IIS6



I am trying to install a httpModule on an IIS 6 web server. I have the same module working on an IIS 7 test box, but we still have a couple of IIS 6 boxes to support.

The module is:

  • c# .NET 2.0
  • registered in the GAC
  • added to the system level web.config (as we want this for all applications on the box). I followed the instructions from http://msdn.microsoft.com/en-us/library/ms227673.aspx. I tried it with both short name (as in the web page) and the full strong name (like the other entries in the <httpModules> section.

So, I am at a loss as it does not appear to even being called and any suggestions would be appreciated.

Thanks in advance,


SharePoint 2010 Long Starting if start workflow programatically


In SharePoint 2010, I'm starting workflow #2 programatically from my workflow #1. See code below:

					SPList currentList = web.Lists[new Guid(ListId)];
					SPListItem currentListItem = currentList.GetItemById(ListItem);

					//resolve any lookup parameters
					string workflowId = base.ProcessStringField(WorkflowIdentifier);

					//find workflow association by name
					SPWorkflowAssociation workflowAssoc = currentList.WorkflowAssociations.GetAssociationByName(workflowId, Thread.CurrentThread.CurrentCulture);

					if (workflowAssoc != null)
						//start the workflow
						SPWorkflow workflow = site.WorkflowManager.StartWorkflow(currentListItem, workflowAssoc, workflowAssoc.AssociationData, SPWorkflowRunOptions.Synchronous);

And workflow #2  will hang with Starting status (1-10 minutes), Then the workflow #2 status would be modified  to Completed.

I couldn't find how to start the workflow # 2 immediately and complete immediately without several minutes delay

Educational question: How server objects are accessed from multiple client threads?

I will appreciate it if someone can help me to undestand how the following scenario works:   There is remoting server that is registered as WellKnownObjectMode.Singleton. Server implementation: It instantiates a class TestServer that implements interface IFoo interface IFoo { IHelper GetHelper() }   interface IHelper { void StoreString(); }   Implementation of TestServer: internal sealed class TestServer: System.MarshalByRefObject, IFoo { private IHelper> helper = new Helper(); public IHelper GetHelper(string helper){return helper;} }   Implementation of Helper: internal sealed class Helper : System.MarshalByRefObject, IHelper { public void StoreString (string val) {}; }   Implementation of a client (simplified; shown to illustrate the question only): static class Program { public static IFoo TestService; public static IHelper Helper; public TestThreads testmultiplecalls; [STAThread] static void Main() { TestService = (IFoo)Activator.GetObject(typeof(IFoo),"ipc://Channel"); Helper = TestService.GetHelper(); testmultiplecalls.Start(); } }   internal class TestThreads { public Start() { for (int i = 0; i < 20; i++) ThreadPool.QueueUserWorkItem((new TestCall(i.ToString())).DoWork); } }     internal class TestCall { private string m_str; public TestCall (string str) {m_str = str;} public void DoWork() { Program.Helper.StoreString(m_str); } }     Que

Failed to generate a user instance of SQL Server due to failure in starting the Process for the User

Could someone help with this please? I'm using VWD 2010 to build a new web site - I tried to add a new database file but it won't do it. I started by clicking on the folder 'App_Data', then right clicking and selecting 'Add new item' - after that I tried to add an SQL Server Database but received this message...  'Failed to generate a user instance of SQL Server due to failure in starting the Process for the User Instance' What does this mean? How do I start the 'Process for the User Instance'?  I imagined all that was done for me at the install stage, when I installed VWD2010, but it appears not.  Thank you for any help at all.    Regards

Starting with Company Website

I have a startup company that I plan on builind and publishing my website for. Nothing major with the first revision - just some information on the company - contact forms and quote request type things, and a blog page to highlight new products etc. I come mostly from using PHP for websites - however since I do a lot of .NET development profesionally I wanted to go the ASP route for my company site. Using Visual Studio 2010 I see I have the option of making an ASP.NET website - or I can go with a project and create an MVC2 application. Would there be any reason to use one over the other for what I wish to acomplish? Will both handle simple things such as in PHP hwere I can create a page and include it dynamically such as using the statement <?php include('header.inc.php') ?> My intention is not to get into a MVC vs WebForms debate - rather I'm trying to make a decision that will allow me to not have to scrap my code when at some point I decide to put in an application such as a portal for photo and video sharing.   Thanks
