Post/Redirect/Get or PRG in short is a common pattern used amongst many web applications, that was designed to prevent duplicate submissions of the forms. Not using such pattern may result e.g. in multiple transactions by POSTing the same form twice, which is something that we definitely do not want to see in our applications. Although, it’s quite easy to be implemented in it’s purest form, it’s a little bit more tricky if we want to save the input data provided by the user (let’s say the form has a lo...

SendGrid is one of the most popular services for delivering the email messages. It allows sending both, the regular, plain text email messages as well as the templated ones (called “transactional”). On top of that, it has also some other cool features such as marketing templates. In this post, I’m going to describe the way that the Warden project has been integrated with this service.

Pagination is (should be) a well-known concept for most of the developers. Whether we want to execute an optimized query on a database that will fetch just a small subset of all available records or increase the web service throughput by returning less data than it’s needed – it all boils down to the efficient usage of the pagination. I’m going to present my approach to this mechanism, both for the MSSQL and MongoDB databases, yet it can be also used in any other scenario such as in memory pagination.

Opis projektu MemoryVisualizera toczy się w kilku wątkach. Jednym z nich jest moja przygoda z F# w kontekście WPF. Po pierwszej części, w której w ogólności opisywałem jak możemy “pożenić” WPF z F#, pora kolejne kroki. Ale wcześniej potrzebne nam będzie krótkie przypomnienie z WPF w C#.

Big changes related to the Warden project – it has been totally rewritten to the new .NET Core in order to support cross-platform capabilities (at least in a future). The functionality per se (including API) didn’t change, yet from now on you can use Warden with the new DNX runtime. If you’re interested in the migration process, a current status of this update (including the supported parts of the project) and what are the next goals – take a look at the whole post.

Dzisiaj artykuł o wstrzykiwaniu zależności. Każda poważniejsza aplikacja w obiektowym języku programowania powinna implementować zasadę odwróconego sterowania (IoC), a jej poszczególne modułu powinny być luźno powiązane (loose coupling).

Quite recently I’ve started working on new features for the Warden project and published the first prelease version to the NuGet (along with other packages that are meant to be additional plugins). In this post, I will discuss the available extensions that are basically responsible for making the fluent API even more fluent and the integrations that are a totally new thing, implemented as separate plugins (similarly to the watchers), which provide a quick access to the external services that can be part...

Jak wiemy delegaty w języku C# zawierają referencje do metod o określonych wcześniej parametrach oraz typie jaki dana metoda zwraca.

Any Kronos client will be available to use three basic commandsInsertGetDelete In future I want to add few more, like Count and GetKeys. Each of requests to the server serialized to binary form is preceded by few bytes of meta-data, including RequestType. In code its represented as a Request class, which in addition to type has two generic methods. At the beginning they might look difficult, but they are quite simple. First of them is responsible for sending any request to the server via special connec...

Nie raz i nie dwa zdarzało mi się mieć potrzebę posiadania więcej niż jednego guzika na formie. Zawsze ale to zawsze miałem problem z tym jak to dobrze rozegrać. Aż wreszcie trafiłem na dobrą odpowiedź na SO.Model i Forma Załóżmy taki model danych, jakiś prosty viewmodel dla użytkownika.: Następnie aby go przesłać z powrotem do kontrolera zdefiniowałem taki model: Typ pola action jest także zdefiniowany. Teraz gdzieś na widoku tworzę formę, która umożliwi mi wpisanie ...
