Delphi’s interfaces are rooted in COM interop, but in most cases are used for non COM purposes. Unfortunately, there are some big limitations with Delphi interfaces, and in a critical area where interfaces are the most useful.
In this article I would discuss Flutter Navigation, Navigation or movement among pages is important business requirement of any application, for example almost every application required login page or option page, where various options could be set based on user input.
Since ~Delphi 2010, we have had generics, attributes, iterators, and some other compiler niceties. While many of the features we would like are difficult to implement, I believe that a few simple language features are long overdue.
This article has been divided into the following high level sections:This article highlights the need for performance testing and how to do it easily, accurately using simple JUnit and maven based Open Source Library. What problems we face typically during the load and stress testing of an application and how we can overcome these issues and make the performance-testing part of the CI build pipeline.
For quite a long time, it was pretty cumbersome to delete a node from the DOM of an HTML document because one had to go to its parent and ask it to destroy its child (by invoking removeChild), like so:
Getting this error in your React and/or Express app?No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
Issues after Upgrade to SQL Server 2017 – Cannot Bulk Load Data Into the Table with Primary Key Constraint on it
Recently, we upgraded one of our Production Systems from SQL 2012 Enterprise to SQL 2017 Enterprise with CU8. The Upgrade process went smoothly without any issues. During the testing process, one such SQL Statement which was fetching the Data from Oracle Linked Server and inserting the same into a table hosted on SQL failed with the below error message:
LEADTOOLS released a new product to complement its world-renowned and award-winning line of imaging SDKs: LEADTOOLS Cloud Services. This high-powered and scalable Web API gives developers a hassle-free interface for integrating advanced recognition and document conversion into any application.
ReactOS is an open source alternative to the Windows operation system. Even if the first version of ReactOS dates back to 1998, there is still no ‘stable’ version of ReactOS. May be, the most important reason is a lack of attention.
Mule is one of the popular middlewares in the market. It is built using Java and supports on-premise and cloud based deployments with the same application code. Development, testing and deployment of Mule based applications can be done in an automated and effective way which shall allow bigger projects with multiple developers working on them to be updated and deployed without much hassle. We will now explore the tools used for different activities and the best practices to be followed in Mule development for an enhanced development and deployment experience.
Dapper is an ORM for .NET and .NET Core, to develop large applications it’s very hard to write code for a lot of objects: entities, contracts and repositories, CatFactory provides an easy way to generate repetitive code and focus on complex logic.
Object Relational Mapping is the process of mapping data types between an object-oriented language as C++ to a relational type system as SQL. So what is the challenge? C++ has different types of primitive types as,intchar, float, double and variations of that. So it’s a real challenge to map all these to an actual SQL type. There may be or may not be an exact type that is similar to the C++ types. Say for,float C++ and SQL may support a different kind of standards too. So there are different tools to do this job. There are a lot of matured libraries too out there in the market. ODB is one that is really nice.
Since 1989, you could specify modifiers for the *this object in the function signature, following the argument list.

I have a homebuilt desktop with an ASUS P6T motherboard. It’s about 7-8 years old, but still quite powerful and functions beautifully. ASUS originally provided PC Probe II to monitor temperatures and fan speeds, but stopped supporting it for the P6T when Windows 10 came out. And since then, I’ve been operating without a satisfactory sensor app. Unfortunately, the 3rd party sensor apps available are a bit quirky, or non-intuitive, or can’t be configured the way I’d like. Then again, perhaps I’m just overly picky.
In this article, I’m going to show you some of the features of the ASP.NET Core WebDemo application dtSearch provides in the dtSearch Engine product. Features include a scrolling word list, faceted search navigation, and multicolor hit highlighting. The features outlined in this article are available in the dtSearch Engine version 7.91 build 8546 or later. Working with the demo also requires Visual Studio 2017 updated to 15.5 or later.
In this article, I am going to explain how we can read email using PoP3 protocol. The sample source code can be found on github.
Today, we will be going through the step by step discussion of how to create dynamic components in Angular 2/4 and how to set the value of dynamic control and get the value from the dynamically generated component. Dynamic Components are those components which generate at runtime. Runtime in the sense, we have a running application and if we want to render some component on any event like button click event, then it will be called the Dynamic Component. So, this article will cover four things about Dynamic Components as follows:
I’d like to share a quick solution for a parallel foreach loop, which can potentially increase the performance of certain applications currently using the built in version introduced in .NET 4.0. This custom version is suited to be used in nested loops, where the outer one needs to be processed sequentially. The number of threads has to be set manually, this could provide additional control over the threads.
ASP.NET Core combined with Angular is becoming an increasingly popular tech stack for building interactive web apps. However, if you want to manage the content of such a web app, your only choice has been to use a headless CMS service. This can be overkill especially for smaller web apps and doesn’t allow for easy previewing of content changes. Lynicon CMS provides SPA content management with preview for ASP.NET Core, which unlike the more usual headless CMS setup allows you to immediately view the effects of your content changes. It is lightweight and quick to set up, and allows for content to be stored in a file rather than a database.
I would be wrong in saying DART is new emerging phenomena in today’s ever-changing programming world, as promised in this article, I would be letting you know more about DART language. For this article, I am taking liberty copying some common text from DART official website, as those information, that are constant like type of keywords or Build-in types. To make this article compliant with rules, I will make sure proper attributions are given.
This article is second in series for learning Dart language, the new kid in the block. Dart Team are upgrading language almost at same pace of Dot Net Core. With Flutter making its main language for app development, I believe it would be in main stream soon.
In this article I would be discussing very important concept in flutter, which is StateFulWidget, If you have read my first article, I created all widget there, which are Stateless whose definition according to Flutter website is that widget is immutable, meaning that their properties couldn’t be change – all values are final, once displayed.
Download sourceThere is nothing like a great Sunday brunch buffet. You can truly have it all, from all-you-can-eat buffets in fancy hotel digs to the plethora of bottomless items to consume. A variety of breakfast-lunch treats await you; mimosas and bloody marys, eggs Benedict, omelets, scrambled eggs, French toast, Belgian waffles, bagels, pasta, chicken, seafood, and carved prime rib. The list is endless. The only limitations are your budget and how much you can and want to eat.
About a month ago, @nikitonsky posted a joke about GitHub redesign on Twitter. I thought the joke is too good to remain merely a joke. So let’s celebrate Microsoft’s acquisition of GitHub with a full-featured Windows theme.
In this article, we will learn how we can create end to end tests (e2e) for our Angular application. We will be using an existing end-to-end testing framework, which is nothing but, Protractor. Protractor runs your tests against your application running in a real browser, in the same way your user may perform the actions. I will be using an existing application which is available in my GitHub profile. The same can be available in the source code section. Please do share your feedback with me. I hope you will like this article. Let’s start coding.

Using Kubernetes to deploy services and support micro-service architectures is nice and is pretty fast. It is just better than setting up things one by one. It`s also really good for DevOps people, trying to automate deployment and patches. However, much like any other system, the question of parametrization is somehow hard to solve. The purpose of DevOps team is to streamline everything and reduce the amount of time a patch gets into production, the purpose of the Dev Team is to deliver and integrate the IDE backbone with the streamline, the Security Team must ensure that everything is as hardened as possible.
