  • What's the lowest cost, legal, Microsoft server stack you can assemble?

    - by McKAMEY
    Assuming that you have an app infrastructure that generally only requires: ASP.NET MVC / C# / .NET Database or NoSQL data store (must be accessible from C#) Here's the challenge to you server gods: What is the least expensive configuration that will allow you to deploy to production in a way that doesn't break any licensing rules? In what ways does this solution differ from the "standard" Microsoft deployment scenario? Where does this solution's performance break down once the app begins to scale? I'm not concerned about the hardware, only the server software itself. I would love to hear about any solutions you've personally put into production. Especially if they are unique alternatives. For ideas, consider some of the possible variations, a) any Microsoft server solutions where they have lowered the barrier to entry to compete with OSS, or b) any OSS alternatives to Microsoft products which perform at a similar level. An example of a): SQL Server 2008 Express Edition SP1 is a 100% free version of SQL Server which will scale to the needs of many smaller / early stage applications. An example of b): running the Mono Framework on Linux. An example of differing from the "standard" stack: running Mono on Linux will require a completely different server OS familiarity. None of the Windows-based knowledge really transfers. An example of breaking down under scale: SQL Server Express will only scale to 1GB of memory and 4GB of disk storage. After that point, the application will need to move to one of the paid versions of SQL Server.

  • Microsoft Channel 9 Interviews Mei Liang to Introduce Sample Browser Extension for Visual Studio 2012 and 2010

    - by Jialiang
    This morning, Microsoft Channel 9 interviewed Mei Liang - Group Manager of Microsoft All-In-One Code Framework - to introduce the newest Sample Browser extension for Visual Studio 2012 &2010.   This extension provides a way for developers to search and download more than 4500 code samples from within Visual Studio, including over 700 Windows 8 samples and more than 1000 All-In-One Code Framework customer-driven code samples. Mei shows us not only the extension, but also the standalone version of the Sample Browser.   http://channel9.msdn.com/Shows/Visual-Studio-Toolbox/Sample-Browser-Visual-Studio-Extension   Microsoft All-In-One Code Framework, working in close partnership with the Visual Studio product team and MSDN Samples Gallery, developed the Sample Browser extension for both Visual Studio 2012 and Visual Studio 2010.  As an effort to evolve the code sample use experience and improve developers' productivity, the Sample Browser allows programmers to search, download and open over 4500 code samples from within Visual Studio with just a few simple clicks.  If no existing code sample can meet the needs, developers can even request a code sample easily from Microsoft thanks to the free “Sample Request Service” offered by Microsoft All-In-One Code Framework.  Through innovations, the teams hope to put the power of tens of thousands of code samples at developers’ fingertips. In short 3 months, the Sample Browser Visual Studio Extension has been installed by 100K global users.  It is also selected as one of the six most highly regarded and commonly used tools for Visual Studio that will make your programming experience feel like never before.   Got to love the All-In-One Code Framework team! You guys know this is THE go to source for code samples. Get this extension and you'll never need to leave VS2012 (well except for bathroom trips, but that's TMI anyway... ;) Read More... From: Greg Duncan (Author of CoolThingOfTheDay) 9/6/2011 12:00 AM The one software design pattern that I have used in just about every application I’ve written is “cut-and-paste,” so the new “Sample Browser” – read sample as a noun not an adjective – is a great boon to my productivity. Read More... From: Jim O'Neil (Microsoft Developer Evangelist) 9/28/2011 12:00 AM Install: http://aka.ms/samplebrowservsx Microsoft All-In-One Code Framework also offers the standalone version of Sample Browser.   The standalone version is particularly useful to Visual Studio Express edition or Visual Studio 2008 users, who cannot install the Sample Browser Visual Studio extension.   From Grassroots’ Passion for Developers to the Innovation of Sample Browser This Sample Browser has come a very long way improving the code sample use experience.  The history can be traced back to a grass-root innovation three years ago.   In early 2009, a few MSDN forum support engineers observed that lots of developers were struggling to work in Visual Studio without adequate code samples. Programming tasks seem harder than they should be when you only read through the documentation.  Just a couple of lines of sample code could answer a lot of questions.   They had a brilliant idea: What if we produce code samples based on developers’ frequently asked programming tasks in forums, social networks and support incidents, and then aggregate all our sample code in a one-stop library to benefit developers?  And what if developers can request code samples directly from Microsoft, free of charge?  This small group of grassroots at Microsoft devoted their nights and weekends to prototyping such a customer-driven code sample library.  This simple idea eventually turned into “Microsoft All-In-One Code Framework”, aka. OneCode.  With the support from more and more passionate developers at Microsoft and the leaders in the Community and Online Support team and Microsoft Commercial Technical Services (CTS), the idea has become a continually growing library with over 1000 customer-driven code samples covering almost all Microsoft development technologies.  These code samples originated from developers’ common pains and needs should be able to help many developers.  However, if developers cannot easily discover the code samples, the effort would still be in vain.  So in early 2010, the team started the idea of Sample Browser to ease the discovery and access of these samples.  In just two months, the first version of Sample Browser was finished and released by a passionate developer.  It was a very simple application, only supporting the basic sample offline search.  Users had to download the whole 100MB sample package containing all samples first, and run the Sample Browser to search locally.   Though developers could not search and download samples on-demand, this simple application laid a solid foundation for the team’s continuous innovations of Sample Browsing experience. In 2011, MSDN Samples Gallery had a big refresh.  The online sample experience was brought to a new level thanks to its PM Steven Wilssens and the gallery team’s effort.  Microsoft All-In-One Code Framework Team saw the opportunity to realize the “on-demand” sample search and download feature with the new gallery.  The two teams formed a strong partnership to upload all the customer-driven code samples to MSDN Samples Gallery, and released the new version of Sample Browser to support “on-demand” sample downloading in April, 2011.  Mei Liang, the Group Manager of Microsoft All-In-One Code Framework, was interviewed by Channel 9 to demo the Sample Browser.  Customers love the effort and the innovation!!  This can be clearly seen from the user comments in the publishing page.   It was very encouraging to the team of All-In-One Code Framework. The team continues innovating and evolving the Sample Browser.  They found the Visual Studio product team this time, and integrated the Sample Browsing experience into the latest Visual Studio 2012.  The newly released Sample Browser Visual Studio extension makes good use of Visual Studio 2012 IDE such as the new Quick Launch bar, the code editor, the toolbar and menus to offer easy access to thousands of code samples from within the development environment.   The Visual Studio Senior Program Manager Lead - Anthony Cangialosi, the Program Manager - Murali Krishna Hosabettu Kamalesha, the MSDN Samples Gallery PM – Steven Wilssens, and the Visual Studio Senior Escalation Engineer - Ed Dore shared lots of insightful suggestions with the team.  Thanks to the brilliant cross-group collaboration inside Microsoft, tens of new features including “Local Language Support” and “Favorite Samples”, as well as a face-lifted user interface, were added to further enhance the user experience. Since the new Sample Browser Visual Studio extension was released, it has received over 100 thousand downloads and five-star ratings.  A customer told the team that he officially falls in LOVE with Microsoft All-In-One Code Framework.   The Sample Browser Innovation for Developers Never Stops! The teams would never stop improving the Sample Browser for developers’ easier lives.   The Microsoft All-In-One Code Framework, Visual Studio and MSDN Samples Gallery teams are working closely to develop the next version of Sample Browser.  Here are the key functions in development or in discussion.  We hope to learn your feedback of the effort.  You can submit your suggestions to the official Visual Studio UserVoice site.  We look forward to hearing from you! 1) Offline Sample Search This is one of the top feature requests that we have received for Sample Browser.   The Sample Browser will support the offline search mode so that developers can search downloaded code samples when they do not have internet access.  This is particularly useful to developers in Enterprises with strict proxy settings. 2) Code Snippet Support and Visual Studio Editor Integration Today, the Sample Browser supports downloading and opening sample project.   However, when developers are searching for code samples, a better user experience would be to see the code snippets in the search result first.  Developers can quickly decide if the code snippet is relevant.   They can also drag and drop the code snippet into the Visual Studio Editor to solve some simple programming tasks.  If developers want to learn more about the sample, they can then choose to download the sample project and open it in Visual Studio. 3) Enterprise Sample Sharing and Searching Large enterprises have many code samples for their own internal tools and APIs that are not appropriate to be shared publicly in MSDN Samples Gallery.   In that case, today’s Sample Browser and MSDN Samples Gallery cannot help these Enterprise developers.  The idea is to create a Code Sample Repository in TFS, and provide an additional Visual Studio extension for Enterprise developers to quickly share code samples to TFS.  The Sample Browser can be configured to connect to the TFS Code Sample Repository to search for and download code samples.  This would potentially enable the Enterprise developers to be more productive. 4) Windows Store Sample Browser With the upcoming release of Windows RT and Microsoft Surface, developers are facing a completely new world of application platform.   Not like laptop, people would often use Microsoft Surface in commute and in travel.  Internet may not be available.  Today’s Visual Studio cannot be installed and run on Windows RT, however, our enthusiastic developers would hope to spend every minute on code.  They love code!   The idea is to create a Windows Store version of Sample Browser. Search and download samples from the online Samples Gallery when the user has internet access. Browse the sample code files and learn the sample documentation of downloaded samples with or without internet access.   In addition to the "browse” function, the Sample Browser could further support “bookmark”, “learning notes”, “code review”, and “quick social sharing". Make full use of the new touch and Windows Store App UI to give developers a new “relaxing” code browsing and learning experience, anytime, anywhere. With Windows Store Sample Browser, developers can enjoy A new relaxing and enjoyable experience for developers to learn code samples You do not have to sit in front of desk and formally open Visual Studio to read code samples.  Many developers get sub-health due to staying in front of desk for a very long time.  With Windows RT, Microsoft Surface and this Windows Store Sample Browser combining with the online MSDN Samples Gallery, developers can sit in a sofa, relaxingly hold the tablet and enjoy to learn their beloved sample code with detailed documentation. Anytime, anywhere Whether you have internet access or not, whether you are at home, in office, or in commute/airplane, developers can always easily access and browse the sample code. Lightweight and fast Particularly for learning a small sample project, the Windows Store Sample Browser would be more lightweight and faster to open and browse the sample code. Please submit your feedback and suggestion to Visual Studio UserVoice.  We look forward to hearing from you and deliver a better and better sample use experience.  Happy Coding!   Special Thanks to People working behind the latest release of Sample Browser Visual Studio Extension and the great partnerships!

  • Preg Expression to identify classes/ids in a CSS file that have no contents

    - by dclowd9901
    I'm in the process of updating some old CSS files in our systems, and we have a bunch that have lots of empty classes simply taking up space in the file. I'd love to learn how to write Regular expressions, but I just don't get them. I'm hoping the more I expose myself to them (with a little more cohesive explanation), the more I'll end up understanding them. The Problem That said, I'm looking for an expression that will identify text followed by a '{' (some have spaces in between, and some do not) and if there are no letters or numbers between that bracket and '}' (spaces don't count), it will be identified as a matching string. I suppose I can trim the whitespace out of the doc before I run a regular expression through it, but I don't want to change the basic structure of the text. I'm hoping to return it into a large <textarea>. Bonus points for explaining the characters and their meanings, and also an expression identifying lines in the copy without any text or numbers, as well. I will likely use the final expression in PHP script. tl;dr: Regular Expression to match: .a_class_or #an_id { /* if there aren't any alphanumerics in here, this should be a matching line of text */ }

  • Visual Studio expression containing a term named "by" cannot be evaluated in the watch window

    - by Andrei Pana
    Consider my C++ code below: int _tmain(int argc, _TCHAR* argv[]) { int by = 10; printf("%d\n", by); int bx = 20; printf("%d\n", (by + bx)); return 0; } which works fine. The funny thing is with the "by" variable. If I try to add a watch for a simple expression that contains by, the result will be CXX0030: Error: expression cannot be evaluated. For example, on a breakpoint on return 0, if I add the following watches I get the results mentioned: by : 10 bx : 20 by + 5 : CXX0030: Error: expression cannot be evaluated bx + 5 : 25 by + bx : CXX0030: Error: expression cannot be evaluated (by) + bx : 30 by + (bx) : CXX0030: Error: expression cannot be evaluated bx + (by) : CXX0014: Error: missing operrand This happens on VS2010, VS2008 on multiple computers. So, more out of curiosity, what is happening with "by"? Is it some kind of strange operator? Why doesn't bx get the same treatment? (I've tried google on this but it is quite difficult to get some relevant hits with terms like "by")

  • Determining whether values can potentially match a regular expression, given more input

    - by Andreas Grech
    I am currently writing an application in JavaScript where I'm matching input to regular expressions, but I also need to find a way how to match strings to parts of the regular expressions. For example: var invalid = "x", potentially = "g", valid = "ggg", gReg = /^ggg$/; gReg.test(invalid); //returns false (correct) gReg.test(valid); //returns true (correct) Now I need to find a way to somehow determine that the value of the potentially variable doesn't exactly match the /^ggg$/ expression, BUT with more input, it potentially can! So for example in this case, the potentially variable is g, but if two more g's are appended to it, it will match the regular expression /^ggg$/ But in the case of invalid, it can never match the /^ggg$/ expression, no matter how many characters you append to it. So how can I determine if a string has or doesn't have potential to match a particular regular expression?

  • Help with Linq Expression - INotifyPropertyChanged

    - by Stephen Patten
    Hello, I'm reading the source code from the latest Prism 4 drop and am interested in solving this problem. There is a base class for the ViewModels that implements INotifyPropertyChanged and INotifyDataErrorInfo and provides some refactoring friendly change notification. protected void RaisePropertyChanged<T>(Expression<Func<T>> propertyExpresssion) { var propertyName = ExtractPropertyName(propertyExpresssion); this.RaisePropertyChanged(propertyName); } private string ExtractPropertyName<T>(Expression<Func<T>> propertyExpresssion) { if (propertyExpresssion == null) { throw new ArgumentNullException("propertyExpression"); } var memberExpression = propertyExpresssion.Body as MemberExpression; if (memberExpression == null) { throw new ArgumentException("The expression is not a member access expression.", "propertyExpression"); } var property = memberExpression.Member as PropertyInfo; if (property == null) { throw new ArgumentException("The member access expression does not access property.","propertyExpression"); } if (!property.DeclaringType.IsAssignableFrom(this.GetType())) { throw new ArgumentException("The referenced property belongs to a different type.", "propertyExpression"); } var getMethod = property.GetGetMethod(true); if (getMethod == null) { // this shouldn't happen - the expression would reject the property before reaching this far throw new ArgumentException("The referenced property does not have a get method.", "propertyExpression"); } if (getMethod.IsStatic) { throw new ArgumentException("The referenced property is a static property.", "propertyExpression"); } return memberExpression.Member.Name; } and as an example of it's usage private void RetrieveNewQuestionnaire() { this.Questions.Clear(); var template = this.questionnaireService.GetQuestionnaireTemplate(); this.questionnaire = new Questionnaire(template); foreach (var question in this.questionnaire.Questions) { this.Questions.Add(this.CreateQuestionViewModel(question)); } this.RaisePropertyChanged(() => this.Name); this.RaisePropertyChanged(() => this.UnansweredQuestions); this.RaisePropertyChanged(() => this.TotalQuestions); this.RaisePropertyChanged(() => this.CanSubmit); } My question is this. What would it take to pass an array of the property names to an overloaded method (RaisePropertyChanged) and condense this last bit of code from 4 lines to 1? Thank you, Stephen

  • What is the regular expression for valdating a 'price' in a jtextfield

    - by wniroshan
    I want to validate a jtextfield as user inputs a price of some item. I have a perfectly working code which beeps and discard if user inputs some character that doesnt match the regular expression.(for regular expression "[0-9]+" it accepts any number of digits and beeps if a letter is given as input) But the problem is I want to validate an input like "12500.00". Format should be any number of digits before decimal point and two digits after the decimal point. eg: ddd.dd I tried the following regular expression. But the i doesnt allow user to input "." character. It allows user to input any number of digits but when "." key is pressed input is not accepted. here is the regular expression I used. "[0-9]+ | [0-9]+. | [0-9]+.[0-9]{1} | [0-9]+{2}" important: user input is validated character by character as the user inputs them to the jtextfield.
