(this is my answer at http://stackoverflow.com/questions/14771474/voice-recognition-in-windows) I’m looking into adding speech recognition to my fork of Hotspotizer Kinect-based app (http://github.com/birbilis/hotspotizer) After some search I see you can’t markup the actionable UI elements with related speech commands in order to simulate user actions on them as one would expect if Speech input was integrated in WPF.

This is a suggestion I’ve just sent in via Visual Studio’s “Send a frown” feature (rewritten here a bit differently from memory, since that feedback channel doesn’t allow you to access your previous feedback as the Microsoft Connect or the Uservoice site does) : Instead of having to write try { … } catch […]...

This is a suggestion I’ve just sent in via Visual Studio’s “Send a frown” feature: Instead of writing statements like: List<CultureInfo> result = new List<CultureInfo>(); in C# I’d prefer to be able to write List<CultureInfo> result = new (); inside the () one would be able to pass contructor parameters and also they […]...

I have a small older Tablet PC (Lenovo S10-3t) that I’m running Windows 10 on, having replaced its internal classic SATA hard disk with an SSD one, and since SSD space is scarce (being more expensive I got a smaller in size disk than the original one), I needed to make free space. Since that […]...

Trying to figure out why, I realized that upgrading from the Windows 10 technical preview version to the final Windows […]...

Introduction A couple of weeks ago, I’ve joined my good colleague Chris Risner at the Channel 9 studio and we’ve talked about API Apps and App Service in general. After receiving quite a few e-mails about the demo I’ve shown, I’ve decided to break it down a bit more and create a step by step […]...

I've been using GUIDs for a long time, even though I had no actual clue of what they were. Well, I did know what they were; they looked like 32 hex digit strings separated by hyphens that looked like that A1F5B524-B197-4787-A6FF-38BC0C8D2B01. And they were unique, so I knew that if I had lots of them within my database tables and inserted yet another one, that would be different from all the rest. Then, one day it came to me that it might be interesting to find out what GUIDs actually are, so I did some search. What is a GUID? GUIDs are stored as 128-bit values but are usually displayed as 32 hexadecimal digits separated by hyphens, so they can be easier for a human to read, for example A1F5B524-B197-4787-A6FF-38BC0C8D2B01. These groups, containing 8, 4, 4, 4 and 12 hex digits respectively. GUIDs (that stand for Globally Unique Identifiers) are also called UUIDs (Universally Unique Identifiers). Actually UUID was the first term to show up. When Microsoft decided to use UUIDs they preferred...

In this post I am going to provide you with a hands-on example on how to use second level caching with Entity Framework 6.0 version. Second Level Caching is one of the features that is not present out-of-the-box in Entity Framework. Second level cache is a query cache. The results of SQL commands are stored in the cache, so that the same SQL commands retrieve their data from the Cache rather than executing the query again against the underlying provider. This can have a performance boost for your application and results in less activity against your database, at the cost of increased memory. There is currently a project in codeplex, EntityFramework.Cache that enables us caching of query results for EF 6.1 applications. Entity Framework is an object-relational mapping (ORM) framework for the .NET Framework.EF addresses the problem of Object-relational impedance mismatch. I will not be talking about that mismatch because it is well documented in many sites on the Internet. Through that framework we can program against...

Ένα από τα services του SQL Server είναι τα Reporting Services τα οποία παρέχουν ένα εξαιρετικά ευέλικτο τρόπο να μεταδίδεται η πληροφορία στους τελικούς χρήστες. Η χρήση τους από τις εταιρίες και τους οργανισμούς έχει αυξηθεί σε υπερθετικό βαθμό και κανείς θα βρει μεγάλο αριθμό από reports να εκτελούνται καθημερινά στις υποδομές αυτών των εταιρειών. Είναι φυσικό κάποια στιγμή να χρειαζόμαστε να παρακολουθήσουμε ποια είναι αυτά που χρησιμοποιούνται, πόσο συχνά χρησιμοποιούνται, πόσο χρόνο χρειάζονται για να εκτελεστούν ποιοι είναι οι χρήστες και ποια reports εκτελούν. Οι παραπάνω λόγοι είναι μερικοί και κάνουν επιτακτική την ανάγκη να έχεις αρχικά ενεργοποιημένο το auditing στα SSRS και στην συνέχεια να έχεις μια διαδικασία που να κάνει την ζωή σου ευκολότερη. Πέρα όμως από αυτούς το τελευταίο διάστημα είχα αρκετές ανάγκες στον εργασιακό μου χώρο για auditing από επιθεώρηση πάνω στoυς SSRS servers που έχω αλλά και πολλές ερωτήσεις από τους μαθητές μου στα πρόσφατα BI σεμινάρια που έκανα. http://www.sqlschool.gr/blog/auditing-reports-execution-in-ssrs-1038.asp...

In this post I am going to provide you with a hands-on example on how to log commands & queries sent to the database by Entity Framework 6.0. You can use the fantastic Entity Framework third party profiler by Hibernating Rhinos if you want. You can find a similar post here . Entity Framework is an object-relational mapping (ORM) framework for the .NET Framework.EF addresses the problem of Object-relational impedance mismatch. I will not be talking about that mismatch because it is well documented in many sites on the Internet. Through that framework we can program against a conceptual application model instead of programming directly against a relational schema-model. By doing so we can decrease the amount of code we do write to access a data storage and thus decrease maintenance time. You can find many posts regarding Entity Framework in this blog. 1) Create an empty ASP.Net Application (Web Forms Application) and give it the name EFLogging. I am using Visual Studio 2013 Ultimate edition. 2) Add a new web...

In this post I am going to provide you with a hands-on example on how to handle efficiently batch operations with Entity Framework and the EF Extended library . You can find another similar post where I demonstrate how to handle batch opration with Entity Framework and the EF Utilities library. Entity Framework is an object-relational mapping (ORM) framework for the .NET Framework.EF addresses the problem of Object-relational impedance mismatch. I will not be talking about that mismatch because it is well documented in many sites on the Internet. Through that framework we can program against a conceptual application model instead of programming directly against a relational schema-model. By doing so we can decrease the amount of code we do write to access a data storage and thus decrease maintenance time. You can find many posts regarding Entity Framework in this blog. As stated earlier it is easy to implement basic CRUD (create, read, update, delete) functionality using EF. There are performances issues when...

In a previous article we talked about multilingual sites. This time we are going to see how we can place that info in the page URL, using ASP.NET's routing system, and create this way an entirely different version of a website, depending on the language selected. Why, you may ask, would I choose Web Forms to do this instead of using MVC's way better routing system? Well, no matter how deprecated Web Forms may become, websites based on that will still remain out there for a long time, so it may still be useful to some. And, after all, no matter what they look like right now, who doesn't like reading stuff concerning Web Forms? Why messing with the URL? To begin with, what we're talking about is not storing the info in the query string; instead we’ll try out the actual URL body. Actually, language info could as well be stored using cookies or other means. What do we get by using this MyWebsite/en/contact.aspx instead of MyWebsite/contact.aspx?lang=en or simply store language on...
