• Lucene.Net support phrases?: What is best approach to tokenize comma-delimited data (atomically) in

  - by Pete Alvin

  I have a database with a column I wish to index that has comma-delimited names, e.g., User.FullNameList = "Helen Ready, Phil Collins, Brad Paisley" I prefer to tokenize each name atomically (name as a whole searchable entity). What is the best approach for this? Did I miss a simple option to set the tokenize delimiter? Do I have to subclass or write my own class that to roll my own tokenizer? Something else? ;) Or does Lucene.net not support phrases? Or is it smart enough to handle this use case automatically? I'm sure I'm not the first person to have to do this. Googling produced no noticeable solutions.

• Breaking changes in .NET 4.0

  - by Andrei Taptunov

  There is a lot of information about new features and classes in new 4.0 however there are also changes that may affect esixting applications, for example Timespan now implements IFormattable and old string.Format() with invalid options will throw exception instead of calling simple ToString(). However, CLR team provides a nice feature to enable behaviour from previous version with configuration setting - TimeSpan_LegacyFormatMode . CLR Inside Out Access to events inside the class where they are declared using += or -= will lead to call add/remove generated accessors that return void. Some code wan't even compile in 4.0. Chris Burrows Blog CAS is deprecated and to enable it one still need to use special setting in configuration - NetFx40_LegacySecurityPolicy So I wonder what are other changes and is it possible to find at least preliminary list of changes that will or may break existing functionality with release of .NET 4.0 ?

• asp.net mvc: handling no-javascript

  - by Bala R

  Hello, I'm working on a asp.net mvc2 app. I have been using jquery to do various different things in all of my views. They are work from a regular browser quite well. But I'm trying to figure out a good way to get the functionality working with browsers with javascript disabled (like mobile browsers). Is there a way to define a whole different view for non javascript browsers? A specific example of what I'm trying to do is, I have a with it's onClick calling a javascript that does $.post() to a controller. What's a good way to make it, so, it works the way it works right now (doing ajax calls) with regular javascript-enabled browsers and it a also works with javascript-incapable browsers, doing a full postback ? Thanks

• ASP.Net WebForms requiredfieldvalidator not working in FireFox?

  - by larryq

  I have a WebForms app that uses a field validator on a dropdownlist. It works in IE but not FireFox. This is pretty straightforward stuff I'm doing. Here are the setups for the dropdown and validator: <asp:DropDownList ID ="dmbFileActNo" runat="server" CssClass="DROPDOWN_MEDIUM" AutoPostBack="True"></asp:DropDownList> <asp:requiredfieldvalidator EnableClientScript="true" id="rfvFileActNo" Display="None" ControlToValidate="dmbFileActNo" Runat="server" InitialValue="-1"></asp:requiredfieldvalidator> I'm running ASP.Net 2.0 on the web server. Javascript is enabled on the FireFox browser-- this problem happens on all FF browsers I've tested, on multiple everyday machines, so I don't believe it's due to a locked down install.

• Submitting AjaxForm with jQuery in ASP.NET MVC

  - by Hadi Eskandari

  I have an ajax form in asp.net mvc which is as simple as this: <% using (this.Ajax.BeginForm("LatestBlogPosts", "Blog", null, new AjaxOptions { UpdateTargetId = "blogPostPanel" }, new { id = "BlogPostForm" })) { %> <div class="panel" id="blogPostPanel"> <img src="/images/ajax-loader.gif" alt="ajax-loader" /> </div> <% } %> I want to invoke the form submit when document is loaded. This should supposedly, call the controller's action and return a result that should be replaced with the placeholder DIV. If I add a SUBMIT button to the form, it works perfectly, but when I invoke the submit via jQuery, the whole page is refreshed, and the content returned by the server is displayed in the newly displayed page. Here's my jQuery code: <script type="text/javascript"> $(document).ready(function() { $("#BlogPostForm").submit(); }); </script> Anyway to do this?

• ASP.NET Session expires in no time?

  - by Galilyou

  Weired problem! ASP.NET Session expires instantly. In my web.config I have this session settings: <sessionState mode="InProc" timeout="10000" /> AFAIK the timeout attribute's value is in minutes and can't be greater than 525,600 minutes (1 year). I don't understand what I am doing wrong here. Why is the session expiring. Is it a server memory issue? I don't think so, the server is pretty descent and it has only one site which isn't doing much after all. Ideas? EDIT: After setting the cookiless attribute to true, and while noticing the session id on the url, I can see that the session id CHANGING. I assume that this means the session is expiring. The IIS Settings are correct AFAIK (the enable session state checkbox is checked, and the value of the time is 20). A Picture is worth 100 words:

• Methods of providing custom reports for an asp.net application

  - by Jarrod

  In our windows application, we used crystal reports. If a customer needed a custom report, we could create it and then send them the rpt file. The customer would then simply add the report file to a custom folder, and could access it directly from our application. Using a web app, how is this possible. It seems like anything created, using ssrs, crystal, or even telerik reporting must be embedded. What are some methods for providing custom reports to users of an asp.net web application?

• ASP.NET MVC View Engine Comparison

  - by McKAMEY

  EDIT: added a community wiki to begin capturing people's experience with various View Engines. Please respectfully add any experiences you've had. I've been searching on SO & Google for a breakdown of the various View Engines available for ASP.NET MVC, but haven't found much more than simple high-level descriptions of what a view engine is. I'm not necessarily looking for "best" or "fastest" but rather some real world comparisons of advantages / disadvantages of the major players (e.g. the default WebFormViewEngine, MvcContrib View Engines, etc.) for various situations. I think this would be really helpful in determining if switching from the default engine would be advantageous for a given project or development group. Has anyone encountered such a comparison?

• Bind list from FormView to model in ASP.net webforms

  - by Monty

  For a large fillin form I use the asp.net FormView for the magic databinding to my model. In this model I've a property called Rides (shown below), which exposes a list, which I obviously not want to be replaced entirely. So I made it readonly. However, this way I can't use the databinding features anymore. Is there a common solution for this problem? public IList<Ride> Rides { get { if (this._rides == null) { this._rides = new List<Ride>(); } return this._rides; } }

• ASP.Net double-click problem

  - by David Archer

  Hi there, having a slight problem with an ASP.net page of mine. If a user were to double click on a "submit" button it will write to the database twice (i.e. carry out the 'onclick' method on the imagebutton twice) How can I make it so that if a user clicks on the imagebutton, just the imagebutton is disabled? I've tried: <asp:ImageButton runat="server" ID="VerifyStepContinue" ImageUrl=image src ToolTip="Go" TabIndex="98" CausesValidation="true" OnClick="methodName" OnClientClick="this.disabled = true;" /> But this OnClientClick property completely stops the page from being submitted! Any help? Sorry, yes, I do have Validation controls... hence the icky problem.

• Global "ajax call" notification with asp.net mvc/jquery

  - by Joel Martinez

  I need to be notified any time a largeish asp.net mvc web application makes an ajax call to the server. We're using both jquery, and the built-in Ajax.* methods to do the remote calls, and I would like a global way of knowing when we make a call without having to manually inject some sort of "IsMakingCall" method to every request. The root problem we're trying to solve is session timeout. If the user leaves a page up and goes to lunch (for example), they get errors when they get back because the ajax call is returning the login page instead of the expected json or partial html result. My idea was to have a js timer which would be reset any time we make an ajax call. That way, if the timer runs out (ie. their session has now timed out) I can just auto-log them out. This is how sites like bank of america and mint.com work. Thanks!

• Asp.net text box is only returning the first value

  - by queryne

  C sharp newbie question...I have a simple asp.net form that has a textbox that collects phonenumbers to send SMS messages. If I bypass the form and hardcode the numbers using the following format: "2133211234",#1233211234" the code works fine. However when i try to use this same format using my form, the sms will ONLY send to the first number. I have a feeling i'm missing out on some property on my form that will accept all of the values. also any idea how how i can add some lines of code that will allow users to enter numbers like this: 3123211234,4123212344 and have it converted to the format above when the number is submitted? Any ideas? Thanks in advance.

• Injecting multi-tenant repositories with StructureMap in ASP.NET MVC

  - by FreshCode

  I'm implementing StructureMap in a multi-tenant ASP.NET MVC application to inject instances of my tenant repositories that retrieve data based on an ITenantContext interface. The Tenant in question is determined from RouteData in a base controller's OnActionExecuting. How do I tell StructureMap to construct TenantContext(tenantID); where tenantID is derived from my RouteData or some base controller property? Base Controller Given the following route: {tenant}/{controller}/{action}/{id} My base controller retrieves and stores the correct Tenant based on the {tenant} URL parameter. Using Tenant, a repository with an ITenantContext can be constructed to retrieve only data that is relevant to that tenant. Based on the other DI questions, could AbstractFactory be a solution?

• Problem sending mail with simple .net application. Server refusal error.

  - by Fatih

  I have a very simple .net application for testing SMTP on .net. But i am receiving this weird error. "System.Net.Mail.SmtpException: Failure sending mail. --- System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it" SMTP server is remote and doesn't need any kind of authentication so i don't need credentials. But i can send mails from this computer with outlook using same smtp server and same smtp settings without any problem. Any ideas? It will be appreciated so much. Imports System.Net.Mail Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim smtp As New SmtpClient smtp.Host = "10.241.128.220" smtp.Port = 25 smtp.Send("[email protected]", "[email protected]", "test", "test") End Sub

• ASP.NET / WCF - Execute Server.Execute Asynchronously

  - by user208662

  Hello, I need to run the HttpContext.Current.Server.Execute method in my ASP.NET application. This application has a WCF operation that does some processing. Currently, I am to do my processing correctly from within my WCF operation. However, I would like to do this asynchronously. In an error to attempt this asynchronously, I tried running Server.Execute in the DoWork event handler of a BackgroundWorker. Unfortunately, this throws an error that says "object reference not set to an instance of an object" The HttpContext element is not null. I checked that. It is some property nested in the HttpContext object that appears to be null. However, I have not been able to identify why this won't work. It happens as soon as I move the processing to the BackgroundWorker thread. My question is, how can I asynchronously execute the Server.Execute method? Thank you,

• ASP.NET MVC Web structure

  - by ile

  This is database structure. It is used to build simple cms in asp.net mvc. Before I run deeper into developing site, I want to make sure if this would be "correct" web structure: Articles: Controllers folder: Create controllers ArticleCategoryController and ArticleController Models folder: ArticleCategoryRepository and ArticleRepository View folder: ArticleCategory folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx); Article folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx) Photos: Controllers folder: Create controllers PhotoAlbumController and PhotoController Models folder: PhotoAlbumRepository and PhotoRepository View folder: PhotoAlbum folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx); Photo folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx) and so on... Is there a better way or this is ok? Thanks. Ile

• Mocking User.Identity in ASP.NET MVC

  - by Trey Carroll

  I need to create Unit Tests for an ASP.NET MVC 2.0 web site. The site uses Windows Authentication. I've been reading up on the necessity to mock the HTTP context for code that deals with the HttpContext. I feel like I'm starting to get a handle on the DI pattern as well. (Give the class an attribute of type IRepository and then pass in a Repository object when you instantiate the controller.) What I don't understand, however, is the proper way to Mock the Windows Principal object available through User.Identity. Is this part of the HttpContext? Does any body have a link to an article that demonstrates this (or a recommendation for a book)? Thanks, Trey Carroll

• Generic HTTP Handler in ASP.Net

  - by Bruno Brant

  Hello all, I want to write a custom HTTP Handler in ASP.Net (I'm using C# currently) that filters all requests to, say, .aspx files, and then, depending on the page name that comes with the requests, I redirect the user to a page. So far, I've written a handler that filter "*", that is, everything. Let's say I receive a request for "Page.aspx", and want to send the user to "AnotherPage.aspx". So I call Redirect on that response and pass "AnotherPage.aspx" as the new page. The problem is that this will once more trigger my handler, which will do nothing. This will leave the user without any response. So, is there a way to send the request to the other handlers (cascade the message) once I've dealt with it? Thanks, Bruno

• Where to get apache poi port for .net

  - by Nassign

  I would like to know if there is a website where I could download the Apache POI ported for .net? I already found this link in the web http://www.apache.org/~avik/dist/poi-2.5.1-dev-20040708.dll But the version of apache poi now is 3.6, I was wondering if there is a latest version out there? Does the apache foundation support such porting? I already tried to search the apache website too with no avail. As for using Microsoft library, the excel interopt is not that good for concurrent processing like a web backend. If I use the DocumentFormat.OpenXML library, I have a limitation of creating office 2007 document only.

• SSL Form Post in ASP.NET MVC 1.0

  - by goombaloon

  I'd like to use SSL for the post action on the login page of my MVC 1.0 app. I've seen some articles related to the [RequireSSL] attribute in ASP.NET MVC Futures. However, since this works using a redirect, I assume it's not an option (can't redirect a POST, correct?). Ultimately, my goal is to get the Html.BeginForm method to render "https://..." as the form's action so that I can secure the information being posted (login info). How have others handled this?

• Does Google index HTTPS ASP.NET pages?

  - by ncakmak

  I have an online application that all of its pages use HTTPS. I have 3 questions: Does Google index HTTPS pages? I have a password protected single ASP.NET page (using HTTPS). Password protection is basically achieved by a Session object. When the correct password is entered, it hides the login panel and displays the same page which has a sensitive data. Is this page indexed by Google? I have a Secure folder that I implemented Forms Authentication. All pages in folder use HTTPS as well. Are the pages in this folder indexed by Google? Thank you for your help, Niyazi

• asp.net 2.0 session timeout

  - by d3020

  I apologize in advance for this likely being asked before. I have an asp.net 2.0 web application and am trying to set the session timeout. My first attempt was to add this to the web.config. < sessionState mode="InProc" timeout="300" Users would tell me though that after about 20 minutes of being idle and then trying to do something again on the site they'd be redirected back to the login page. So now I'm trying timeout="60" in my < forms tag in the web.config. I also tried Session.Timeout=60 in my global.asax. Should these work? Do I need something else? Thank you for your time and help.

• Membership provider stopped working on using Membership Provider in ASP.Net MVC

  - by Michael Meadows

  I have a production ASP.Net MVC application that has been using the membership service. It has worked fine, up until today. Nothing has changed on the server, but I now have this error: System.Configuration.Provider.ProviderException: The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version. I checked the asp_schemaversions table, and it looks fine. Please any help would be appreciated.
