• Web API Presentation at DC DNUG

  - by Steve Michelotti

  This Tuesday (July 19), I’ll be presenting the ASP.NET Web API at the DC DotNet Users Group. Abstract: Modern web applications have seen an explosion in Web API creation. Twitter, Facebook, Google, Azure, you name it – it is becoming essential to provide a Web API so that consumers can build applications and mashups on top of your services. Web 2.0 has shown a trend away from SOAP towards a REST architecture style. With the new ASP.NET Web API, Microsoft is now providing first-class support for HTTP services including tools to apply the richness of a REST architectural style. This demo heavy presentation will show how the new ASP.NET Web API will enable you to build rich HTTP services in a REST architectural style while leveraging custom media types, custom HTTP handlers, jQuery and more! The presentation will also cover new features of MVC 4 including Razor enhancements, Web Optimizations, and more.

• The way to the future - Hybrid systems

  - by BuckWoody

  I've written before (as have others) about the dangers of an "either/or" mentality with various technologies, including the "cloud". Companies are starting to understand this message - I've been traveling a lot this year from Alaska to California, from the UK to Copenhagen, Denmark, talking with companies that are implementing Hybrid systems, and giving presentations on how to implement one. I'm doing another of these Monday of next week, in Boston here in the US. You can read about it and register here (it's a free event) and learn not only more about Hybrid systems using on-premises databases and Windows Azure, but more about SQL Server as well from other speakers.

• Check SQL Server Virtual Log Files Using PowerShell

  In a previous tip on Monitor Your SQL Server Virtual Log Files with Policy Based Management, we have seen how we can use Policy Based Management to monitor the number of virtual log files (VLFs) in our SQL Server databases. However, even with that most of the solutions I see online involve the creation of temporary tables and/or a combination of using cursors to get the total number of VLFs in a transaction log file. Is there a much easier solution?

• New .Net Authentication in 4.5.1

  - by Aligned

  Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/11/05/new-.net-authentication-in-4.5.1.aspxThere has been a lot of traffic on my post about Simple Membership that came with the File new Project MVC 4 in 2012. I was reading the release notes for Visual Studio 2013 and .Net 4.5.1 and it mentioned a new/updated Authentication approach. “ASP.NET Identity is the new membership system for ASP.NET applications. ASP.NET Identity makes it easy to integrate user-specific profile data with application data. ASP.NET Identity also allows you to choose the persistence model for user profiles in your application. You can store the data in a SQL Server database or another data store, including NoSQL data stores such as Windows Azure Storage Tables” There’s a great page on the asp.net site that gives an introduction, overview, how to use it, and how to migrate to it. I won’t be doing a new project for awhile at work, but I’ll definitely be looking into this more when I get the time.

• Whar parts of functionality should be refactored into a directive? [AngularJS]

  - by Sprottenwels

  I am creating an application from legacy code using AngularJS. I wonder what parts of my code should be moved into a directive. For example, i had thought of moving a table which is used multiple times across the application into a directive. The tables alter from headings and size. Is it worth the effort or even a good practice to turn such things into their own directives or should i create each table in a unique way?

• Differences between a retail and wholesale website, and how difficult would it be to integrate them? [closed]

  - by kmy

  I was told to come here for some guidance, I know that my questions can be quite broad, but I just really want some kind of direction to go towards (links, articles, etc). So here it goes: For the past month I have been planning and started implementing a wholesale website, but plans got changed on me and I need to allow both retail and wholesale orders which will also depend on whether the account is a regular customer or also has a seller account. There are various types of products and it has been decided that I would use subcategories as tables to organize them and allow various specific item fields. So here are some of my specific questions: How different is the database structure for each item to be available for both wholesale and retail? Will it just be adding a quantity column and have two different pricing, or much more complicated? I am unaware if there's any price tables but would that be more difficult? They use Quickbooks POS software, how difficult/inefficient will it be to update inventory quantities if they have like 2000-4000 products? And what would be the best ways to extract the information and update the system? I know it export an excel spreadsheet so maybe a suggested php plugin for it? How difficult is this project in your professional opinion, and how big should a team usually be? (At the moment it is just me.) Projected time for planning, implementation, and quality assurance in accordance to team size? I am an entry level developer and I know that I do not have enough knowledge to direct myself on this website...What kind of web developer skills will I need to find to help me? (My company is willing to hire people to get this website done as fast as possible.) Also, what would be some great questionnaires to ask the product stakeholder about what he wants from the website? (He has made it clear he is neither computer or internet savvy...) Sorry for the amount of questions, I'm an entry level web developer and do not have a senior to look up to for guidance. I have knowledge in HTML, CSS, Javascript, jQuery, PHP, MySQL, phpMyAdmin. I have never used any frameworks like Zend, Magento, etc, and is doing this all from scratch. So far the website is built in an object oriented way, MVC architecture to the best of my abilities, but I have many doubts because I would really want to have this done right. If I have been unclear on some parts please tell me and I'll add more detail. I'm sure I'll have more additional questions later on, if anyone is open to that please tell me. Thanks in advance!

• Linq The specified type 'string' is not a valid provider type.

  - by Joe Pitz

  Using Linq to call a stored procedure that passes a single string, The stored procedure returns a data set row that contains a string and an int. Code: PESQLDataContext pe = new PESQLDataContext(strConnStr); pe.ObjectTrackingEnabled = false; gvUnitsPassed.DataSource = pe.PassedInspection(Line); gvUnitsPassed.DataBind(); pe.dispose(); When the code runs an exception gets called below: The exception is thrown at the IExecuteResult result = statement: Enclosed is my result class in the designer.cs file. [Function(Name = "dbo.PassedInspection")] public ISingleResult<PassedInspectionResult> PassedInspection([Parameter(Name = "Model", DbType = "VarChar(4)")] string model) { IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), model); return ((ISingleResult<PassedInspectionResult>)(result.ReturnValue)); } public partial class PassedInspectionResult { private string _Date; private int _Passed; public PassedInspectionResult() { } [Column(Storage = "_Date", DbType = "string NULL")] public string Date { get { return this._Date; } set { if ((this._Date != value)) { this._Date = value; } } } [Column(Storage = "_Passed", DbType = "Int NULL")] public int Passed { get { return this._Passed; } set { if ((this._Passed != value)) { this._Passed = value; } } } } } I have other stored procedures with similar arguments that run just fine.

• What is wrong with this solution? (Perm-Missing-Elem codility test)

  - by user2956907

  I have started playing with codility and came across this problem: A zero-indexed array A consisting of N different integers is given. The array contains integers in the range [1..(N + 1)], which means that exactly one element is missing. Your goal is to find that missing element. Write a function: int solution(int A[], int N); that, given a zero-indexed array A, returns the value of the missing element. For example, given array A such that: A[0] = 2 A[1] = 3 A[2] = 1 A[3] = 5 the function should return 4, as it is the missing element. Assume that: N is an integer within the range [0..100,000]; the elements of A are all distinct; each element of array A is an integer within the range [1..(N + 1)]. Complexity: expected worst-case time complexity is O(N); expected worst-case space complexity is O(1), beyond input storage (not counting the storage required for input arguments). I have submitted the following solution (in PHP): function solution($A) { $nr = count($A); $totalSum = (($nr+1)*($nr+2))/2; $arrSum = array_sum($A); return ($totalSum-$arrSum); } which gave me a score of 66 of 100, because it was failing the test involving large arrays: "large_range range sequence, length = ~100,000" with the result: RUNTIME ERROR tested program terminated unexpectedly stdout: Invalid result type, int expected. I tested locally with an array of 100.000 elements, and it worked without any problems. So, what seems to be the problem with my code and what kind of test cases did codility use to return "Invalid result type, int expected"?
