• Is it possible to tell IIS 7 to process the request queue in parallel?

  - by Uwe Keim

  Currently we are developing an ASMX, ASP 2.0, IIS 7 web service that does some calculations (and return a dynamically generated document) and will take approx. 60 seconds to run. Since whe have a big machine with multiple cores and lots of RAM, I expected that IIS tries its best to route the requests that arrive in its requests queue to all available threads of the app pool's thread pool. But we experience quiet the opposite: When we issue requests to the ASMX web service URL from multiple different clients, the IIS seems to serially process these requests. I.e. request 1 arrives, is being processed, then request 2 is being processed, then request 3, etc. Question: Is it possible (without changing the C# code of the web service) to configure IIS to process requests in parallel, if enough threads are available? If yes: how should I do it? It no: any workarounds/tips? Thanks Uwe

• In JavaScript, How to convert string into Date ? Where string may have different culture format.

  - by user328973

  Hi I am getting DateString in JavaScript from the TextBox like, var dateString = document.getElementById('<%= txtEffDate.ClientID %>').value; dateString value may be in following format. en-US - "4/29/2010" fr-FR - "29/04/2010" de-DE - "29.04.2010" it-IT - "29/04/2010" es-ES - "29/04/2010" zh-CN - "2010/4/29" ja-JP - "2010/04/29" sv-SE - "2010-04-29" And converting this to Date Object as follows, var d1 = new Date(dateString); though its giving me the wrong result like for fr-FR "29/04/2010" == "Fri May 4 00:00:00 UTC+0530 2012" Which is completely irrelevant, How should I get the correct Date ? I have also set < globalization culture="auto" / in web.config & < asp:ScriptManager ID="scr1" runat="server" EnableScriptGlobalization="true"/

• What are the "Navigation Properties" in this data model for?

  - by d03boy

  I've been wondering how to properly set up many-to-many relationships in ASP.NET MVC 2 using Linq2Sql for quite some time now. I found this blog post that seems to have a similar model layout as mine. If you take a look at the first screenshot showing the data model you can see that each model has "Navigation Properties" at the bottom of it. What exactly is this and why don't my models have them? I have the proper foreign keys put in to place. Most specifically, I am looking at the relationship between the Article and Category models since that is the only many-to-many relationship that I see and that's what I'm trying to model. Obviously I use an intermediary joining table between these two tables but I am having trouble understanding the proper methodology for modeling that relationship and I'm not finding this information anywhere on The Google.

• Prevent bot from crawling certain areas of site.

  - by Skoder

  Hey, I don't know much about SEO and how web spiders work, so forgive my ignorance here. I'm creating a site (using ASP.NET-MVC) which has areas that displays information retrieved from the database. The data is unique to the user, so there's no real server-side output caching going on. However, since the data can contain things the user may not wish to have displayed from search engine results, I'd like to prevent any spiders from accessing the search results page. Are there any special actions I should take to ensure that the search result directory isn't crawled? Also, would a spider even crawl a page that's dynamically generated and would any actions preventing certain directories being search mess up my search engine rankings? edit: I should add, I'm reading up on robots.txt protocol, but it relies on co-operation from the web crawler. However, I'd also like to prevent any data-mining users who will ignore the robots.txt file. I appreciate any help!

• Want to load jquery dialog from a different web-page

  - by Jake

  I'm a bit of a n00b with jquery so this one is probably an RTFM question: I'm writing an application to create a somewhat complex record for my client. Building the record requires doing a couple of server side searches inside a dialog. Right now I have everything framed up in 1 file (asp.net) and it's ok. But I can see as I add the business logic and the communication with the server this is going to get really ugly. I'm alreay putting most of the javascript in external files, but I'd like to move the HTML for the dialogs out too. How do I get the jquery dialog method to load the dialog body from the html files? Something like: getDialogHTML(dialogHolderDiv); <---magic goes here var dialogOptions = { ... }; $("#"+dialogHolderDiv).dialog(dialogOptions); $("#"+dialogHolderDiv).dialog('open'); any help will be apperciated .

• Is Lucern.net good choice for website search of 1M item product database? (giving up on SQL Server

  - by Pete Alvin

  We currently have in production SQL Server 2005 and we use it's full text search for a eCommerce site search of a million product database. I've optimized it as much as possible (I think) and we're still seeing search times of five seconds. (We don't need site scrawl or PDF (etc.) document indexing features... JUST "Google" speed for site search.) I was going to buy dtSearch but now I realize I can just use Lucerne.net and save the $2,500 for two server license. I read on a post that Lucerne.Net is not good for website searches. Has anyone else used Lucerne.Net from ASP.Net? Does it take a lot of memory? Any problems? Any comments?

• Gridview with row headers

  - by Seagull

  I am using the ASP.NET3.5 gridview control in a new project. My problem is that the gridview presents data in basic tabular format, whereas I want a grid with row header / grouping behaviors. An example of this would be Outlook web interface, which can group emails by date, as well as allowing you to select individual emails to display. My problem: I can't see how this could be easily done with Gridview? I did find a product called Telerik that has a seemingly fancy Gridview, but I am hesitant to spend money on a single components that now also locks me into a third-party framework...

• How can I determine if there is an open source software for a specific purpose?

  - by afsharm

  Hi, We are going to write an entire new application for a reservation system. In this system experts specify their free time in elaborated calendar and users seek them through searched and finally reserve the expert and his time. We prefer to find an open source program like this and try to evolve it instead of creating it from scratch. In this manner our time is saved and that open source program will be completer too. We are a entire .NET (ASP.NET, C#, NHibernate) company. We have same problem to find open source applications for our new projects. Any help is highly appreciated.

• Help needed with InvokeRequired for Web.UI

  - by Ali

  I have a multi-threaded application in C# which tries to write to a TextBox in a Windows.Forms created by another thread. As threads cannot modify what has not been created by them, I was using InvokeRequired as shown on the code below, to solve this problem. public delegate void MessageDelegate(Communication message); void agent_MessageReceived(Communication message) { if (InvokeRequired) { BeginInvoke(new MessageDelegate(agent_MessageReceived), new object[] { message }); } else { TextBox1.Text += message.Body; } } Now I need to do the same for a TextBox in an ASP.NET app, but apparently neither InvokeRequired nor BeginInvoke exist for TextBox in a Web.UI. What can I do?

• How to keep a process running on a remote windows server

  - by DutrowLLC

  I need to implement a background process that runs on a remote windows server 24/7. My development environment is C#/ASP.NET 3.5. The purpose of the process is to: Send reminder e-mails to employees and customers at appropriate times (say 5:00PM on the day before a job is scheduled) Query and save GPS coordinates of employees when they are supposed to be out on jobs so that I can later verify that their positions were where they were supposed to be. If the process fails (which it probably will, especially when updates are added), I need for it to be restarted immediately (or within just a few minutes) as I would have very serious problems if this process failed to send a notification, log a GPS coordinate, or any of the other tasks its meant to perform.

• MVC architectural question - Where should payment processing go?

  - by Keltex

  This question is related to my ASP.NET MVC 2 development, but it could apply to any MVC environment and a question of where the logic should go. So let's say I have a controller that takes an online payment such as a shopping cart application. And I have the method that accepts the customers' credit card information: public class CartController : Controller CartRepository cartRepository = new CartRepository() [HttpPost] public ActionResult Payment(PaymentViewModel rec) { if(!ModelState.IsValid) { return View(rec); } // process payment here return RedirectToAction("Receipt"); } At the comment process payment here should the payment processing be handled: In the controller? By the repository? Someplace else?

• Creating a Web Wrapper for COM and OCX

  - by balexandre

  Hi guys, Today we have a windows application that, using an OCX, creates a web page (visible by a WebBrowser control in a small .NET WinForm application) and communicates through COM to the main application/client. (not relevant but this is Pascal) I'm currently responsible to re create this application in a web environment so we can have the same functionality shared through Web as the user can see the same in a Web Browser. The Windows application has almost 4 years on it and I need to re create everything from scratch, and all the bugs/features find in the future in the Windows Application I have to re create them again in the Web... Ohh well, you can see where this will end. I was thinking... is there any way I can create a Wrapper, even using 3rd party commercial objects, to: Communicate with the COM Object Can expose the content of the OCX (this in my most confortable language, ASP.NET C#, but other are welcome) I was thinking out loud, can this be accomplish with a Java Applet? Any ideas or any point to the right road will be appreciated.

• Developer tool for configuring IIS6

  - by Marc Gravell

  edit: IIS6; I'm not sure IIS7 is an option in the immediate future... From a developer angle, I am constantly changing my IIS settings, or need to merge settings from other teams into different VMs. The "Save Configuration to Disk" has never really worked well for me. Because we are making lots of small changes, web installation projects have never really worked either... Tools aimed for the web-admin aren't necessarily a good fit for the developer - we have different aims and needs. Does anyone have a script / tool / utility that would allow us to quickly configure IIS? In particular: remove everything (start clean) add a load of virtual directories, each mapped to application base paths set as an application set the app-pool (we'll assume the app pool already exists) set the ASP.NET version to 2.x if needed from some find of flat input list (any format would do).

  - by Vy Clarks

  I have a asp FileUpload control in my aspx page. And the code behind to check file's extension and then insert them into database: private string Write(HttpPostedFile file, string table) { string fileNameMain = Path.GetFileName(file.FileName); // check for the valid file extension string fileExtension = Path.GetExtension(fileNameMain).ToLower(); if (fileExtension.Equals(".pdf") || fileExtension.Equals(".doc")) { ...insert fileupload into database } else { LabelError.Text = "Extension of files are not allowed."; return null; } } With the code above, it checks the extension and then show the message "Extension of files are not allowed." in a LabelError if the fileupload is not allowed. Now, I'm required to do the "check-extension" in the other way: at the moment the client click and choose FileUpload, an alert show "Extension of files are not allowed.". I need a way to make an alert show at the momment the FileUpload choosed in browser. Help!!!!

• Login to SQL Server Express via development environment (VS2010)

  - by Sanarothe

  Seems like I'm missing something simple, but my attempts to connect to SQL Server Express have failed. I feel like I need to add privileges for my account but I'm not sure where to do it. Dev Env: VS 2010 (Web) SQL: Sql Server Express 2008 OS: XP Trying to open a connection to database returns: Cannot open database "|DataDirectory|DropData.mdf" requested by the login. The login failed. Login failed for user 'devel.' I created the database using the interface in VS 2010 (Add new item - DB File) but my ASP.Net class only covered design-time access and not access in code, so I'm not familiar with what to do. I created a user (Devel) using SQL Server Management Studio to avoid connecting as SA, but couldn't figure out how to give any SQL-level access rights to this account. Any ideas? Thanks, Cameron

• Hardest javascript debugging problem ever

  - by Craig

  We have an ASP.NET application and when running on client site they often get null reference Javascript errors. As with all these errors the information IE6 displays is less than helpful. But the problem is as soon as I install IE script debugger and try and debug a bit more the error becomes non-reproducible.When script debugger is not installed then the error occurs again. Are there any other tools that could be helpful for javascript debugging on client site. The error is also not produced with IE7 or Firefox.

• jquery datepicker predefined date

  - by r3try

  This might seem like a stupid easy question to some of you, but i'm new to jquery and can't get my datepicker to work like it should. This is my textbox where the datepicker is attached to: <asp:TextBox runat="server" ID="StartMonth" AutoPostBack="true" class="month-picker" /> and here is how i attach the datepicker. (I have multiple TextBoxes where the datepicker should be attached to, so i used the class attribute instead of the id.) $(".month-picker").datepicker({ dateFormat: 'MM yy', changeYear: true, yearRange: '-9:+9' }); What i want to archive is when i click into the textbox where the text is "August 2012" it should set the pre-selected date of the datepicker to this date. Can anyone help? Kind regards.

• Scraping *.aspx content using Python

  - by tomato

  I'm having difficulties scraping dynamically generated table in ASPX. Trying to scrape the gas prices from a site like this GasPrices. I can extract all the information in the gas price table (address, time submitted etc.), except for the actual gas price. Is there a way I could scrape the gas prices? i.e. somehow get a text representation of it. I'm not very familiar with ASP/ASPX - but what's being generated now is not showing up in the final HTML. I'm using Python to do the scraping, but that's irrelevant unless there's a specific library... Thanks in advance.

• What does a modern, standard Microsoft-based technology stack look like?

  - by Sean Owen

  Let's say I asked Microsoft to describe the perfect, modern, Microsoft-based technology stack to power a standard e-commerce web site, which perhaps has a simple 2-tier web/database architecture. What would it be like? Yes, I'm just looking for a list of product / technology names. For example, in the J2EE world, I might describe a stack that includes: J2EE 6 standard JavaServer Faces Glassfish 3 MySQL 5.1.x I'm guessing this stack includes some combination of .NET, SQL Server, ASP.NET, IIS, etc. but I am not familiar with this world. Looking for ideas on the equivalent in Microsoft-land.

• Silverlight Cannot find XML data source

  - by Nick

  Hello.. I am very new to Silverlight development. I understand that this is client side technology therefore the paradyme is differant from that of conventional ASP.NET development. Having said that, I don't understand where my server side code is deployed. I have a silver light \ MVC application. I am trying to read an XML document from within my 'Models' folder. The following peice of code is executed from within a class that is in the same location as the XML document, 'Models'. The load() results in a SystemIOFileNotFound exception. I noticed that when building the application the XML document is not laid down in the same location as the web project's assembly. I assume this is specific to the fact that this is a Silverlight project. Can someone tell me what I'm missing? _xdoc = new XDocument(); _xdoc = XDocument.Load(new Uri("videos.xml",UriKind.Relative).ToString());
