• ASP.Net MVC Web App not running

  - by Aidan Host

  Hi, I developed an ASP.Net MVC v1 web application and it ran fine on our server. The client wanted to move to another server, and the site does not run on the new host's server. The new server specs: Windows 2008 ASP.Net Framework v4 ASP.Net MVC 2 (afaik its included with .Net v4) IIS 7.5 (afaik) Error Message: Could not load file or assembly 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. My understanding is that it should be backwards compatible. Is the app really trying to run in ASP.Net MVC v1 when v2 is available? I have already tried deploying the MVC .dlls to the Bin folder, but it did not work. I also tried changing all the system.Web.Mvc Version values (in the web.config for the web app) from 1.0.0.0 to 2.0.0.0, which also did not work. Any assistance will be greatly appreciated.

• How can I receive messages using over http without MSMQ

  - by pduncan

  I need a reliable messaging framework that runs over http/https (due to client security requirements) and that doesn't use MSMQ (because some clients will use Windows XP Home). The clients only need to be able to receive messages, not send them. We already have a message queue on the server for each user, and the receivers have been getting messages by connecting to an HttpHandler on the server and getting a Stream from WebResponse.GetResponseStream() We keep this stream open, and pull messages off of it using Stream.Read(). This MOSTLY works, but Stream.Read() is a blocking call, and we can't reliably interrupt it. We need to be able to stop and start the receiver without losing messages, but the old stream often hangs around, even after we call Thread.Abort on its thread. Any suggestions?

• How to implement Self-host WCF data serivces (http://localhost:1234/myDataService.svc/...)

  - by warmcold

  I have a project that needs to implement WCF data services (OData) to retrieve data from a control system (.NET Framework Application). The WCF data service needs to be hosted by the .NET application (No ASP.NET and NO IIS). I have seen many WCF Data Service examples recently; they are all hosted by ASP.NET application. I also see the self-host (console application) examples, but it is for WCF Service (not WCF Data Service). Here is my question: It is possible to have a standalone .NET Applications to host WCF Data Services ((http://localhost:1234/mydataservice.svc/...). If yes, can someone provide an example? Thanks.

• Can I use WCF on Visual Studio 2005?

  - by Hemant

  I am about to start a project which consumes third party web services. Because of a legacy system, I am told that I can only use Visual Studio 2005/.NET 2.0. (Though I would have preferred Visual Studio 2008 on .NET 3.5) My understanding is that WCF was released with .NET 3.0. So is there any possibility to use WCF on Visual Studio 2005 by using just the WCF assemblies of .NET 3.0? I will then try to convince them that it is just like using external framework which doesn't disturb anything.

• Really basic Django E-commerce? Where do I start

  - by Andrew

  I'm trying to set up a really basic e-commerce site with Django, and am trying to figure out the best place to start. I am relatively comfortable with the framework itself, but have never done any sort of e-commerce development in any language, so I want to learn about some best practices so I don't make any huge or obvious mistakes. I've looked at Satchmo, and even went as far as installing and playing around with it, but it looks like way more than I want. I basically want to show users a list of things, and let them click a button to buy one. No cart, no shipping, just click a button, connect with Authorize.net (or something similar) to do the transaction, and then display a confirmation page. Any suggestions or online tutorials people have found helpful? Even perhaps a tutorial in another language. Or maybe a really lightweight Django plugin that doesn't try to do everything like Satchmo? I've been coming up with very little so far. Thanks!

• Hibernate HQL to basic SQL

  - by CC

  Hello everybody, I working on a project with Hibernate and we need to replace Hibernate with some "home made persistence" stuff. The idea is that the project is big enough, and we have many HQL queries. The problem is with the queries like select a,b from table1, table2 on t1.table1=t2.table2 Basically all joins are not supported by our "hand made persistence" stuff. What I would need, is to be able to do some sort of transcoder, which will take as a input the HQL queries and output some SQL, but the basic SQL without joins, something like (a dumb example) select a from table1 where t1 IN ( select b from table2) I hope you get the idea. My persistence layer does not supports joins. Does anybody has any idea about something like that? Some framework, or something? Thanks alot everybody. C.C.

• Getting started with Rails testing

  - by yuval

  I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucamber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

• A btter way to represent Same value given multiple values(C#3.0)

  - by Newbie

  I have a situation for which I am looking for a more elegant solution. Consider the below cases "BKP","bkp","book-to-price" (will represent) BOOK-TO-PRICE "aop","aspect oriented program" (will represent) ASPECT-ORIENTED-PROGRAM i.e. if the user enter BKP or bkp or book-to-price , the program should treat that as BOOK-TO-PRICE. The same holds good for the second example(ASPECT-ORIENTED-PROGRAM). I have the below solution: Solution: if (str == "BKP" || str == "bkp" || str == "book-to-price" ) return "BOOK-TO-PRICE". But I think that there can be many other better solutions . Could you people please give some suggestion.(with an example will be better) I am using C#3.0 and dotnet framework 3.5

• vs2010 Cache SQL data incorrect fields

  - by mickartz

  OK, I found a walkthrough on msdn for what I was after (offline database cache). However when I let the wizard create a local database from my online sql server the timespan fields are converted to a string?? Now I know the suggestion was to create my own local database and then use the MS Synch framework...however...this proclaims to do it "out of the box" However now I've a dataset which I've no idea how to use, and a database newly formed (for the synched cache) taht I will have to use Ling to Entities with(??) meanwhile I have this weird timespan to string conversion? should I give up now or push on? can i overwrite the the .designer.cs? typeof(string) to typeof(timespan)? damn wizards!!

• .NET make a copy of an embedded file resource to the local drive

  - by Matt H.

  Hi, i'm new to the realm to working with Files in .NET I'm creating a WPF application in VB.NET with the 3.5 Framework. (If you provide an example in C#, that's perfectly fine.) In my project I have a Template for an MS Access database. My desired behavior is that when the users clicks File--New, they can create a new copy of this template, give it a filename, and save it to their local directory. The database already has the tables and some starting data needed to interface with my application (a user-friendly data editor) I'm thinking the approach is to include this "template.accdb" file as a resource in the project, and write it to a file somehow at runtime? Any guidance will be very, very appreciated. Thanks!

• What grid distributed computing frameworks are currently favoured for trading systems

  - by Rich

  There seems to a quite a few grid computing frameworks out there, but which ones are actually being used to any great extent by the investment banks for purposes of low latency distributing calculation? I'd be interested to hear answers covering both windows,Linux and cross platform. Also, what RPC mechanisms seem to be favoured most? I've heard that for reason of low latency and speed, the calculations themselves are quite often written in C++/C as calculations running on VMs are several orders of magnitude slower than native code. Does this seem to be a common scenario in practice? e.g distributed .NET grid framework running calculations written in native c++/c?

• Efficient multiple services exposed over c# .NET remoting using more channels or end points?

  - by wb

  I am using remoting over TCP for a prototype distributed server application where I want to have varying multiple services exposed from each remoting server process. In some cases I want the services running from the same process but I don't want whatever is using the service to care about that. I am wondering is it more efficient to have multiple services in the same process going over the same remoting channel distinguished by endpoint URI/URL or should I be creating new channels on different ports for each service in the same process? Using up ports isn't so much of a problem as the number of services will be low and the network and machine configuration is completely controlled. Also its not clear to me if remoting sends the URI string for every single message or just at connection time, and whether if the remoting framework is intelligent enough to reduce work if calls are made on the same machine and even the same process? Thanks in advance.

• html vertical space between blocks appears

  - by cosmorocket

  Please have a look at this page www.pixeli.ca/issue. I have begun making a page layout using CSS framework 960.gs. My problem is that there is some strange space appears between block with top image and blue block with "hello" string. So you can see a green stripe there that shouldn't be visible at all. I tried different variants and have no idea what's wrong with it. I noticed that it happens only with the block with images inside them, but if there is only text, no space happens. Thanks.

• sql boolean truth test: zero OR null

  - by AK

  Is there way to test for both 0 and NULL with one equality operator? I realize I could do this: WHERE field = 0 OR field IS NULL But my life would be a hundred times easier if this would work: WHERE field IN (0, NULL) (btw, why doesn't that work?) I've also read about converting NULL to 0 in the SELECT statement (with COALESCE). The framework I'm using would also make this unpleasant. Realize this is oddly specific, but is there any way to test for 0 and NULL with one WHERE predicate?

• How do I find the root path of a website from a dll?

  I have a C# website. It references several compiled dlls. My dlls need to access folders on the website. How do I find the root path of the website from the dlls? I've tried System.Environment.CurrentDirectory - "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE" Assembly.GetExecutingAssembly().Location - C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files...... I was going to use System.Web.HttpContext.Current.Server.MapPath() but System.Web.HttpContext.Current is null. Thanks!

• Joomla! 2.5 use login data from another database

  - by user1756746

  I have a hard question. I'd like the joomla login does not use its own database for users/password but I want to use my database users with my table fields, my passwords etc.. I don't know from where start, I thought I could edit database request for login to my db or create a little script to automatically add the users on joomla database. I tried to see components/com_users/views/login/tmpl/default_login.php but it seems that there is nothing. Can someone help me figure out what to change? Maybe the simple thing is import my database users into database user joomla, is there any plugin or something else that you know? p.s. I use Clarion theme build on Gantry framework, Joomla! 2.5.6 Stable, PHP 5.2.17

• When is it appropriate to do interaction based testing as opposed to state based testing?

  - by Praneeth

  Hi, When I use Easymock(or a similar mocking framework) to implement my unit tests, I'm forced to do interaction-based testing (as I don't get to assert on the state of my dependencies. Or am I mistaken?). On the other hand if I use a hand written stub (instead of using easymock) I can implement state based testing. I'm quite unclear if I want to go with interaction based testing or state based testing. I'm biased and I want to use Easymock, but I'm not sure if there would be any side-effects that I may have to face in the future. Can anyone please throw some light on this? Thanks in advance!

• Example of contravariance

  - by Misha

  I am thinking of the following example to illustrate why contravariance is useful. Let's consider a GUI framework with Widgets, Events, and Event Listeners. abstract class Event; class KeyEvent extends Event class MouseEvent extends Event trait EventListener[-Event] { def listen(e:Event) } Let Widgets define the following methods: def addKeyEventListener(listener:EventListener[KeyEvent]) def addMouseEventListener(listener:EventListener[MouseEvent]) These methods accept only "specific" event listeners, which is fine. However I would like to define also "kitchen-sink" listeners, which listen to all events, and pass such listeners to the "add listener" methods above. For instance, I would like to define LogEventListener to log all incoming events class LogEventListener extends EventListener[Event] { def listen(e:Event) { log(event) } } Since the trait EventListener is contravariant in Event we can pass LogEventListener to all those "add listener" methods without losing their type safety. Does it make sense ?

• How can I enable auto-updates in a Qt cross-platform app?

  - by FX

  I love applications that are able to update themselves without any effort from the user (think: Sparkle framework for Mac). Is there any code/library I can leverage to do this in a Qt app, without having to worry about the OS details? At least for Windows/Mac/user-owned-linux-binaries. I could integrate Sparkle on the Mac version, code something for the linux case (only for a standalone, user-owned binary; I won't mess with distros packaging, if my program is ever packaged), and find someone to help me on the Windows side, but that's horribly painful. Surely I'm not the only one who wants to provide this to users?

• How can I intercept a Tomcat request at socket level?

  - by Miguel Pardal

  Hi, I'm doing a performance study for a web application framework running on Apache Tomcat 6. I'm trying to measure the time overhead of handling HTTP requests. What I would like to do is: / // just before first request byte is read long t1 = System.nanoTime(); // request is processed... // just after final byte is written to response long t2 = System.nanoTime(); / Then I would compute the total time (t2 - t1). Is there a way to do this? Thanks for your help!

• Simple 2 way encryption for C#

  - by Matt Dawdy

  I'm looking for very simple encrypt and decrypt functionality for some data. It's not mission critical. I need something to keep honest people honest, but something a little stronger than ROT13 or Base64. I'd prefer something that is already included in the .Net framework 2.0 so I don't have to worry about any external dependencies. Pre-emptive EDIT: I really don't want to have to mess around with public/private keys, etc. I don't know much about encryption, but I do enough to know that anything I wrote would be less than worthless...in fact, I'd probably screw up the math and make it trivial to crack.

• How to access Dispatcher in Silverlight tests?

  - by bluebit

  I am using the SL unit test framework for tests (http://code.msdn.microsoft.com/silverlightut). My code is heavily client-server communications dependant, and I access the GUI dispatcher in several places to make sure important data is only accessed on a single thread (ie. the GUI thread). This dispatcher seems unavailable in the unit tests - I have tried using Deployment.Current.Dispatcher and even created an instance of a blank control to try use its own dispatcher, but both don't work. The code inside of Dispatcher.BeginInvoke() just never executes, even if I include a Thread.Sleep afterwards.
