Using Multiple Return Values instead of Exceptions
Today we are going to show you how to get started parsing Command Line arguments, following on from our series on .NET 5.
Command Line Applications, also known as Console Applications, are programs built to be used from a shell, such as cmd or bash. They have been around since the 1960’s, way before Windows, MacOS, or any other graphical user interface (GUI) came to be.
Windows Services have been a foundation of Windows since Windows NT. They help users, or system admins, manage long-running programs that execute in their own Windows sessions. It is fairly trivial to set them up and start whenever the computer boots, for example. Since they can be completely UI-less, they provide an interesting approach for tasks that don’t require user interaction, such as looking for directory or file updates, pooling a service, or logging data. Windows itself uses services for many common task that an operating system should do, like Windows Defender, and Windows Update.
This blog post will demonstrate how to build a system file watcher as a Windows service that runs in the background, and classifies images using the WinML model we’ve previously set in my previous blog post.
Unicode Art (with the source code)
Compared to ASCII art, its Unicode analog is easier for automatic generation; at the same time, the result can look more impressive, due to better tonal set of the characters — there are so many of them in Unicode!
Human visual perception is amazingly complicated thing. It presents a lot of subtle problems of the visual presentation of everything. On the other hand, the power of human perception is dramatically underestimated. Accordingly, the preparation of the photographs or other images for the conversion into a good-looking Unicode Art form takes some artistry.
At the same time, the application offered in the present article helps to get some basic experience pretty quickly, because, with almost every small reasonably contrast and clear photograph on input, it produces quite recognizable rendition of the character-composed image. Let’s see how it is done.
Today, JSON is one of the main formats for representing complex structures and data exchange. Therefore, all major programming languages have built-in support for working with it. C# is no exception. In this article, I would like to tell you about an easy way to work with JSON file in C#/.NET. I would like to show you simple examples with this format.
Atata Framework - C#/.NET web test automation full featured framework based on Selenium WebDriver. It uses fluent page object pattern; has unique logging system; contains triggers functionality; has a set of ready to use components. Supports .NET Framework 4.0+ and .NET Core/Standard 2.0+.
The Framework basically consists of the following concepts:
- Components (controls and page objects)
- Attributes of the control search
- Settings attributes
- Triggers
- Verification attributes and methods
In this article, you will learn how to implement pagination over REST API, to manage voluminous data with considerable ease, using pagination technique.
Indulge a requirement of records pagination over REST API on massive data sources. So we came up with this solution using REST API, hope it will help in your endeavors as well. This article is an extension of my previous datatable.net pagination article, so try not to put plagiarism charges on me. The intention was to perform specific and multiple column searches, sorting, dynamics page sizing, have elegant code structure, least coding effort, and most of all, performance.
In this article, you will learn how to read your applications's package identity as well as the package version using their dedicated native implementations for that task.
Version and the build numbers work together to uniquely identify a particular App Store submission for an app. The conventions for how these numbers work together are verified by automatic processes when you submit your app to the App Store or Play Store, so understanding how these numbers work and how they are intended to be used will help you save time when submitting your app. In this article, we can learn how to get App version and build numbers through programming in Xamarin.Forms.
In this article, you will learn how to add a bunch of images to a Xamarin.iOS project. In this post, I am going to show you a faster way to add image assets to your Xamarin.iOS project in Visual Studio.
Delete all the records from the table using Entity Framework Core.
User account management is fundamental to any web API. This article is a concise discussion and implementation of the basics. This article is not intended to discuss user roles and permissions - all I'm presenting here is how an example web API the management of user accounts by and administrator or by the user themselves. The code here is essentially a template and needs to be modified according to your use case requirements.
I find FluentMigrator to be a great tool for making revisions to a database. It's an easy to learn "fluent" syntax and accommodates 90% of what I need to do, and if there's something unique that needs to be done it provides an Execute method for custom SQL operations. As I find it useful to provide web API endpoints for performing migrations and checking on the migration version, this article is about how to do that in .NET 6.
This is a tutorial article that starts with an introduction to Fluent Interface Pattern in C#. This is followed by a discussion of Hierarchical Fluent Interface. Finally, quite a complicated inheritance problem with Fluent Interface Pattern is discussed. The intended audience is intermediate level C# programmers and above.
This article proposes considering multithreading in C#. It discusses the Thread class, creating threads, ThreadStart delegate, threads with parameters, thread synchronization, thread monitors, AutoResetEvent class and why it is needed, mutexes and semaphores.
%LOCALAPPDATA%\Xamarin\iOS\Provisioning, there’s a folder for each of those.------------------------------
We have two ways to DEBUG: USB Cable or WiFi.
➖ Connecting with the USB Cable: Just connect your device to your computer and it will be available to debug! (Your device gets this as a default way.)
➖ Connecting with WiFi: Another way is to connect through a Wifi network, which is very useful because we don’t have to have the cell phone connected to a USB cable, and it allows us to have a further distance between the device and the computer. To do this, you must follow the following steps:
- Go to Settings
- Tap WiFi option them select the WiFi network that the device is connected to.
- From the information that displays, we’ll save the IP Address.
- Connect your Android device to your computer via USB.
- Next, restart ADB so that it uses TCP on port 5555. From a command prompt, type the following command:
adb tcpip 5555. - Disconnect the USB cable from your device. (It can’t look for devices that are connected via USB.)
- Configure ADB so that it will connect to your Android device on the port that was specified in step 5 above:
adb connect XXX.XXX.X.XXX:5555(Your_IPAdress:5555)
And done! Our device has gotten WiFi connection! 😎
