• Where can I find the Visual Studio 2010 RTM release notes?

  - by Lernkurve

  Question Where can I find a list of changes introduced to Visual Studio 2010 Ultimate RTM that were added since Visual Studio 2010 Ultimate RC? In fact, I'm only interested in changes related to MS Test Manager 2010 and Coded UI Tests. Where I have looked so far I have searched the Internet, looked for a readme.txt in the installation folder, looked into the Visual Studio help (F1) and browsed the "What's new in Visual Studio 2010" section on MSDN. No luck. Found Scott Guthrie's blog post Visual Studio 2010 and .NET 4 Released, but that's not exactly what I am looking for. It's not a changelog since VS2010RC. I suppose there is no such file because they made too many changes to document and hand out to end users. But if there was, I'd be glad if someone could point me to it. Thanks.

• JSINQ (Linq for JavaScript library) sub-queries (how-to)

  - by Tom Tresansky

  I'm using this library: jsinq. I want to create a new object using subqueries. For example, in .NET LINQ, I could do something like this: from a in Attendances where a.SomeProperty = SomeValue select new { .Property1 = a.Property1, .Property2 = a.Property2, .Property3 = (from p in People where p.SomeProperty = a.Property3 select p) } such that I get a list of ALL people where Property3 value matches the attendance's Property3 value in EACH object returned in the list. I didn't see any sample of this in the docs or on the playground. Made a couple tries of it and didn't have any luck. Anybody know if this is possible and how to?

• Azure, SLAs and CAP theorem

  - by dayscott

  Azure itself is imo PaaS and not IaaS. Do you agree? MS gurantees an availability of 99% and a strong consistency. You can find MS SLAs here: http://www.microsoft.com/windowsazure/sla (three SLAs Uptime: http://img229.imageshack.us/img229/4889/unbenanntqt.png ) I can't find anyhing about how they are going to archive that. Do they do backups? If Yes: How do they manage consistency? According to the Cap theorem (http://camelcase.blogspot.com/2007/08/cap-theorem.html ) their claims are not realistic. 2.1 Do you know detailed technical stuff about the how they are going to realize the claims about consistency and availability? On the MS page you'll find three SLAs .docs, one for SQL Azure, the second for Azure AppFabric/.Net Services and the third for Azure Compute&Storage.(Screenshot in 1.) How can one track whether SLAs are violated? Do they offer some sort of monitor, so I don't have to measure the uptime by myself?

• Using generics with XmlSerializer

  - by MainMa

  Hi, When using XML serialization in C#, I use code like this: public MyObject LoadData() { XmlSerializer xmlSerializer = new XmlSerializer(typeof(MyObject)); using (TextReader reader = new StreamReader(settingsFileName)) { return (MyObject)xmlSerializer.Deserialize(reader); } } (and similar code for deserialization). It requires casting and is not really nice. Is there a way, directly in .NET Framework, to use generics with serialization? That is to say to write something like: public MyObject LoadData() { // Generics here. XmlSerializer<MyObject> xmlSerializer = new XmlSerializer(); using (TextReader reader = new StreamReader(settingsFileName)) { // No casts nevermore. return xmlSerializer.Deserialize(reader); } }

• How to automate a build for a Visual FoxPro project?

  - by jpierson

  I'm interested in figuring out how to automate a build from Visual FoxPro similar to how we can build .NET projects from the command line using MSBuild. It seems that it is possible to pass command line arguments to VFP.exe which may include the ability to specify some initial startup prg that runs however it is unclear how well starting up the IDE will work from non-interactive accounts such as the Network Service on Windows which is likely where an automated build would run. Has anybody attempt this before or read about anybody attempting to script a VFP build like this? I would be grateful for any pointers that may lead me to a solution.

• What's the next big thing after LINQ?

  - by Leniel Macaferi

  I started using LINQ (Language Integrated Query) when it was still in beta, more specifically Microsoft .NET LINQ Preview (May 2006). Almost 4 years have passed and here we are using LINQ in a lot of projects for the most diverse tasks. I even wrote my final college project based on LINQ. You see how I like it. LINQ and more recently PLINQ (Parallel LINQ) give our jobs a great boost when it comes to more programming power and less lines of code leading us to more expressive and readable code. I keep thinking what could be the next big language improvement for C# after LINQ. I know there are some promissing language features coming as Code Contracts, etc, but nothing having the impact that LINQ had. What do you think could be the next big thing?

• Sitemaps on multiple front end servers using a http handler, is that a good idea?

  - by Rihan Meij

  Question 1 We would like to generate a site map for our CMS site We have multiple front end servers with approx a million articles. Environment multiple MS SQL servers multiple front end servers (load balanced) ASP.net - and IIS 6 Windows 2003 To have the site maps (the site map index file, and the site map files) physically on the front end servers will be a operations nightmare and error prone. So we are considering using http handlers instead so that it does not matter what server gets the request, it will be able to serve the correct xml file. Question 2 If we ping Google each time we publish a new article will that effect us negatively if that happens more than once a hour. Thanks!

• What technical skills needed for algorithmic trading, HFT, etc?

  - by alchemical

  I'm interested in getting into developing trading systems, black box, HFT, etc. My primary experience is with C# and .Net (7 years). I've also done some sockets programming. I have some experience in finance working on analysis applications (2 years). My goal is to move into developing automated trading systems for a hedge fund, bank, etc. Is there any way to learn the skills needed for this without somehow getting the job first? I've looked at the open source tradelink, IB interactive brokerage, etc. I'm playing around with this framework, and may hook it up and do some paper trading. However, I'm not sure if this has much relationship with how a well-funded entity would be conducting a high-level automated trading operation. I.e. would the tools and frameworks they prefer be a totally different skill-set? Also wondering if I need to learn C++ and/or Java for these types of apps.

• f# iterating over two arrays, using function from a c# library

  - by user343550

  I have a list of words and a list of associated part of speech tags. I want to iterate over both, simultaneously (matched index) using each indexed tuple as input to a .NET function. Is this the best way (it works, but doesn't feel natural to me): let taggingModel = SeqLabeler.loadModel(lthPath + "models\penn_00_18_split_dict.model"); let lemmatizer = new Lemmatizer(lthPath + "v_n_a.txt") let input = "the rain in spain falls on the plain" let words = Preprocessor.tokenizeSentence( input ) let tags = SeqLabeler.tagSentence( taggingModel, words ) let lemmas = Array.map2 (fun x y -> lemmatizer.lookup(x,y)) words tags

• Difference between implementing an interface and applying an attribute in C#

  - by RemotecUk

  This might be a stupid question but Ill ask anyway, I was reading "OOP Demystified: A Self-Teaching Guide by Jim Keogh and Mario Giannini" chapter 11 which covers interfaces. The examples in this book are C++. I noticed that C++ uses ISerializable to make a class serializable which you would implement where as in C# you just attribute the class with the [Serializable] attribute. What is the key difference here? Is it that with an interface you must provide the implementation where as if you attribute something the compiler will work out the implementation for you? I guess that with the [Serializable] attribute the .Net framework uses reflection to make the serialized object from the actual object. That said is it possible in that case to have an [Disposable] attribute or using my theory above the framework wont know how to actually dispose of an object hence you have to do it yourself? Would be grateful for a clarification. Thanks.

• Forth: free video tutorials?

  - by Peter Mortensen

  Can you recommend any free Forth video tutorials (except for following) ? The only one I know of is Samuel A. Falvo's excellent "Over The Shoulder Episode 1: Text Preprocessing in Forth". MPEG. 102 MB. There are also videos from the annual Forth Day, but I don't consider those to be tutorials. (Unfortunately Forth is, like R, C, C++, Java, C#, D, COM, .NET, F# and Frontier, an unspecific search term. Search tip for Forth: qualify it with "ans" - as in ANS Forth, the ANSI Forth Standard.) Accumulated based on answers and other information: Introductions to Forth Forth. By Ben Stiglitz. At RubyConf 2008 Orlando Florida, U.S.A. 13 min 35 secs. 32 MB. MP4.

• Rate limiting Django admin login with Nginx to prevent dictionary attack

  - by shreddies

  I'm looking into the various methods of rate limiting the Django admin login to prevent dictionary attacks. One solution is explained here: simonwillison.net/2009/Jan/7/ratelimitcache/ However, I would prefer to do the rate limiting at the web server side, using Nginx. Nginx's limit_req module does just that - allowing you to specify the maximum number of requests per minute, and sending a 503 if the user goes over: http://wiki.nginx.org/NginxHttpLimitReqModule Perfect! I thought I'd cracked it until I realised that Django admin's login page is not in a consistent place, eg /admin/blah/ gives you a login page at that URL, rather than bouncing to a standard login page. So I can't match on the URL. Can anyone think of another way to know that the admin page was being displayed (regexp the response HTML?)

• I want to port my delicious bookmarks to my website

  - by puneet

  I started building a app that will automatically download my delicious bookmarks, and save to a database, so they I can view them on my own website in my favoured format. I am forced to use oAuth, as I have a yahoo id to login to delicious. The problem is I am stuck at the point where oAuth requires a user to manually go and authenticate. Is there a code/ guidelines available anywhere I can follow? All I want is a way to automatically save my bookmarks to my database. Any help is appreciated. I can work on java, .net and php. Thanks.

• XBAP usage and maturity issues

  - by Yonatan Karni

  we're considering migrating our UI to XBAP. we've chosen XBAP despite knowing the clients must have .net pre-installed, since we're not targeting the masses but rather IT professionals in the corporate environment, and it's a way to preserve our investment (in a WPF based UI in a client-server architecture) and enjoy web deployment. however, we are concerned about the maturity of the platform/architecture and it's adoption. do you know of any commercial applications out there using XBAP, and do you have any experience using it? can you elaborate on that experience? also, as @Murph suggested, can you think of strong reasons to prefer clickOnce over XBAP (or the other way around)?

• ruby xmpfilter on windows

  - by dreftymac

  Has anyone out there ever gotten xmpfilter to work on windows? xmpfilter "unterminated string meets end of file" is the error. The only Google hit is in Japanese: google://xmpfilter "unterminated string meets end of file" http://www.unkar.org/read/pc12.2ch.net/tech/1249687283 For background, the desired feature from xmpfilter is to get automatic "eval" annotations of Ruby sourcecode: Before: a = "bravo alpha charlie" # => b = a.split # => b.sort! # => After: a = "bravo alpha charlie" # => "bravo alpha charlie" b = a.split # => ["bravo", "alpha", "charlie"] b.sort! # => ["alpha", "bravo", "charlie"]

• Working with expression AST:s

  - by Marcus

  Hi, Is there any best practice when working with AST:s? I have a parsed expression AST. ConstantExpression, BinaryExpression etc. I want to populate a GUI-dialog with information from the AST, and it's here where I get kinda confused because my code gets pretty messy. Example: expression = "Var1 > 10 AND Var2 < 20" I want to populate two textboxes with value 10 resp. 20 from the AST. What I'm doing now is a recursive method that checks for correct child expression-types (with .Net Is-operator) and acts accordingly and the code is really "smelly" :) Is there any design pattern, like Visitor or such, that makes this somewhat easier/more readable/maintainable ?

• Override HTML Anchor Link Target inside iFrame

  - by wag2639

  We're calling an ad from an ad network to dynamically load an add using JavaScript. It makes an iFrame with the actual ad in it, a picture wrapped in an anchor tag with the target=_top. Is there a way from our page to change its target and capture the attempt to change our page. Also, our page is loaded in a C#.net program using a WebControl (I forget the actual control being used since it was a while ago). We can change the C# code but we really prefer not to because then we'd have to test it and everything. Is there a way to do this with JavaScript or JQuery?

• Why can't I see the 'dataset project' property in Visual Studio DataSet designer?

  - by Ryan

  Hi, I am trying to follow 'n tier app design' tutorials and they tell me to set the DataSet Project property from the Data Set Designer in VS, to split table adaptors and entities into seprate projects. I can't see that property! (I'm looking in the same place shown on the videos... all other properties match) Does anybody know why? The video is here http://windowsclient.net/learn/video.aspx?v=14625 (4:36 is where the property is set) I'm using VS c# 2008 Express, with SQL Server Express 2008. Thanks a lot for any help Ryan

• jQuery/AJAX type-ahead/auto-complete

  - by Prasad

  I have read several articles/questions/forums discussing the best auto-complete plugin for jQuery. After trying several good ones, I've realized a flaw in most. If you are looking up countries and type 'In', a couple of countries show up. If you continue typing I-n-d-i-a, this results in 5 AJAX calls (see http://www.freeimagehosting.net/uploads/6f1bcd69e1.png) its quite natural that India is a subset of In, so why call again? We need to simply filter the retrieved list client-side. Anyone knows about such an implementation? What is the status of the Jquery Autocomplete feature? I read at StackOverflow that it is no longer available with Jquery; but the Jquery website has a 'New' mark besides the link to Autocomplete. Thanks

• Why would a CSV attachment appear as text in the body?

  - by David

  Hi all I've just implemented some code that emails a bunch of our clients with a CSV file attachment. Some (not many) have got back to us complaining that they don't get an attachment at all - just the CSV text inside the body of the email. Most however are fine. I suspect that it's different mail clients that are treating the attachment differently but I don't have enough info yet to be sure. I'm using .NET's MailMessage class with the Attachment.CreateAttachmentFromString() method. The MIME type I'm specifying for the attachment is text/csv. Anyone have any idea what the heck is going on? Ta muchly David

• Windows Forms in Visual Studio Express

  - by noname

  Good day, can I ask one question about Windows Forms? As far as I know Windows Forms is Win32 wrapper like MFC, created for use with .NET. But, what I dont know is, can you use windows forms and compile directly to native code? Becouse in Visual Studio Express, there is windows forms available only for CLR. And, there is no GUI tool for use with win32 project. I expected there will be one, since its called Visual, like Visual Basic has. Thanks.

• windbg/cdb hangs when bp hit

  - by aaron

  I have a problem where cdb or windbg hangs frequently, but not all the time, when I'm debugging with it and I attach to a specific application on my machine. I found this article: http://www.nynaeve.net/?p=164 which talks about a symbol loading race condition being the problem, but I can force load the symbols, actually have a breakpoint in-app work, and still have it hang elsewhere. Here is the stack from cdb itself when I attach to it with another debugger: ntdll!NtReadFile kernel32!ReadFile cdb!ReadNonConLine cdb!ConIn cdb!MainLoop cdb!main !analyze reports that APPLICATION_HANG_BusyHang is the problem bucket, and 'ReadNonConLine' is the offending function. as far as the stack goes: ffffffff`fffffffe 00000000`00000000 00000001`3f641498 00000000`0014ea50 : kernel32!ReadFile+0x86 00000000`000002a4 00000000`0014ebb0 00000000`00001000 00000000`00000000 : cdb!ReadNonConLine+0x6d ReadNonConLine has the string "g" at 0014ebb0 passed as a param, which may be part of the command I had at the hanging breakpoint (it was something like bp foo "dt a; g") ReadFile takes a handle as its first parameter. I'm surprised by the value -2, though, that doesn't look valid. Any help is appreciated. Thanks! Aaron

• Problem using Blend 3 Interaction.Behaviours in VS2010

  - by Andre Luus

  There seems to be a problem with support for the Interactivity namespace of Blend 3 in the VS2010 xaml editor. I have the following installed: VS2010 Blend 3 + Blend 3 SDK I am trying to compile a demo project that is targeted at .Net 4 Client Profile and has a reference to System.Windows.Interactivity (in the Blend 3 folder). In the object browser everything appears to be fine. I can also access Interaction.Behaviours from code-behind, but if I put the namespace xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" in the xaml file and try to use it, the intellisense is blank. If I copy something in there anyway, the compiler says: The tag 'Interaction.Behaviors' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactivity'. Do I need to install Blend 4 RC or something?
