Designing a well-crafted and easily manageable software system is the ultimate goal of any professional developer. Therefore, we need the best windows development tool and coding practices to achieve this goal. Clean coding is one such core practice that can help us in our mission. However, unfortunately, many new developers are not even aware of clean coding. So, let us briefly discuss clean coding methods and their relationship to the best windows development tool, Delphi. What is clean code? By definition, clean code is well crafted, easy to understand, and easy to change because change is inevitable in any usable software. To change a software system, we need to understand it. If the code is poorly written and messy, it would not be cost-effective to change it. On the other hand, if code follows a well-thought structure, is well organized, and is easily understandable, it is clean code. What are the basic concepts of clean code windows development? Clean coding is a discipline in itself now. Here is a brief overview of some basic concepts of clean coding. Why is code duplication bad? Clean code does not repeat itself because code duplication generates many problems, from bug fixing to updating and maintenance. What is the “boy scout” rule? Always leave the code in a better state than you found it. If you always check out with a little bit better code, then the quality and clarity of your codebase will increase over time. On the other hand, if you do not follow this rule, the code will rote over time, and it will be a nightmare to maintain. Do you have empathy? Show that you care about the person who will read your code. For example, I once saw that the previous electrician marked a wire with a sticker in electrical wiring. It was a good help for the new electrician to understand and repair the circuit. Both of us were thankful for this act of kindness of the previous electrician. Why is naming so important? A code is full of variables, constants, methods, arguments, classes, directories, etc. If a developer takes some time and care in naming these entities, it will drastically increase the readability of the code. There will not be a need for many comments to explain these variables. Choose a name that clearly describes their purpose, functionality, and usage when naming your entities. What is the Single Responsibility Principle (SRP)? If a function or class does more than one thing, you have not designed it well. On the other hand, making an entity do only one thing well improves its readability, usability, and changeability. How many function parameters are ideal? Single parameter functions and procedures are ideal. However, you can increase this limit by up to three parameters. You should pass an object instead of many parameters for anything above that. This arrangement will improve readability, and it is easier to change if necessary. Are you directly using numbers and strings? If a code uses a value like ’33’ or ‘m’ in assignments, it is challenging to guess its purpose. Therefore, you should name these as constants and then use those constants in all assignments. With this arrangement, if you need to change it in the future, you can easily do it in one place only. […]

A control or component is a user interface (UI) element that displays content or enables interaction. Components are the building blocks of the user interface. A ‘pattern’ is a recipe for combining several controls to make something new. This article gives a guide for Windows UI development and design guidance for better UI development with modern Windows UI toolkits. The Delphi VCL and FMX frameworks have dozens of built-in controls for you to use, ranging from various simple buttons to powerful data components like the list view grid view. Moreover, the form designer and the LiveBindings designer in RAD Studio provide a great environment to create a bold, scalable UI that looks great on all devices and screen sizes. Delphi VCL & FMX Delphi’s RAD Studio IDE offers a WYSIWYG design experience with drag-and-drop components for visual GUI design. Let’s suppose you choose the FireMonkey (FMX) framework for building GUI apps? In that case, the designed GUI can be viewed using native Android, iOS, Windows, macOS styling, or custom styles and can simulate app appearances within mobile devices of varying screen sizes. But we have another library called Visual Component Library that creates actual native Windows-based applications with direct access to the hardware. You can benefit from pure native device hardware performance.  Delphi’s VCL has been in active development for more than two and a half decades. At least one application in your Windows device is built with Delphi and Visual Component Library. For instance, KMPlayer, WinRAR, MySQL Admin Tools, AIMP, BurnAware, Dev-C++, EarMaster, FL Studio, Nero Burning Rom, Ultra ISO, Total Commander, TeamSpeak, Hamachi (Gamers know it well), Age of Wonders, and many more applications.  Applications built with Delphi VCL give an authentic, native experience with high performance. The VCL includes a robust OpenTools API and component model making it easy for others to extend the IDE and build reusable components and libraries. That’s why you can see a massive pool of 3rd party component markets. This creates a robust environment for developers to make any application. Microsoft Windows has several design systems that you can follow to create GUI apps. For example, Windows Classic Design, Luna and Aero designs, Microsoft Metro, and the latest and most loved one is the Microsoft Fluent Design System. Fluent Design is used as a guideline for all Windows 10/11 devices, and transition to Fluent is a gradual long-term project. The Fluent Design System preserves the clean look and feels with blurred translucency. With Delphi VCL, you can turn your Windows Classic applications into Fluent Design using styles. Furthermore, it can alter any part of the UI element to something unique. Delphi VCL and FMX components can also be resized and have their properties adjusted in the Object Inspector without touching code, allowing rapid prototyping through visual development. Windows UI or just WinUI is Microsoft Windows’ native layer. Most of the new Windows development tools are utilizing it to create an environment to build desktop apps with their technologies. WinUI contains controls and fluent design systems that designers and developers need to develop Windows applications. WinUI is the latest GUI framework such as WinForms, WPF, and UWP. We can say that WinUI has improved over the years and got all the experiences from other frameworks like UWP XAML apps. For instance, WinUI 2 contains […]

At Softacom, as a software company specializing in mobile and Windows app development using Delphi, we often integrate clients’ software with 3rd party services using API. In this article we show you how to automatically create posts on Facebook from your Delphi apps using the Facebook Graph API. Facebook is the world’s most popular social platform used by businesses to communicate with their clients, and not only.The daily amount of information (texts, videos, images, urls) being posted in Facebook business accounts is huge and keeps growing. That’s why big companies often apply software solutions to distribute content effectively and in time.In this article we’ll show you how to automate the process of content posting and updating through Facebook API (namely Facebook Graph API).We’ll develop a Delphi FMX software application to post on a user’s Facebook page.The whole process can be split into the following steps: Create a Facebook app Make the required adjustments in the app Debug and test queries using the built-in Facebook API debugging tool called Graph API Explorer Develop a Delphi Fmx (cross-platform) software application Post some content on a Facebook page To work with Facebook Graph API we’ll use GET, POST and DELETE methods and requests. The server response will be in JSON format. How to create a Facebook application entry To work with Facebook Graph API you first need to sign in with your Facebook account (sign up if you do not have one). Then you need to go https://developers.facebook.com and register as a developer. Then you need to confirm your email address Select the profile type and click “Complete registration”. To start using the Facebook API you need to create a facebook app in My Apps . Select “Company” application type. Next, enter the application name, select its purpose and click Create App. Next enter your Facebook login password Congrats! You’ve just created a Facebook app.  How do I get an access token so I can write my own apps to post to Facebook? Now we need to get a token to access the page and configure the appropriate permissions to start posting. To get the token run Graph API Explorer. The Graph API Explorer will help us get the access token so that we can execute test queries and post to the page ( Softacom’s test page). To work with the Facebook app select it from the drop-down lis. To get the token to access the page, choose Get Page Access Token from the User or Page. Next, click Continue Select the page you need and save the ID for further posting: Both options have to be turned on. In our case Softacom. Click Further. The access token has been generated. How do I check my app can use the Facebook Graph API? We can test the Facebook Graph API with the built-in debugging tool “Graph API Explorer”. First, let’s test a GET request to get the profile name and identification number. Select your page (Softacom) Set up special permissions for posting (publish_to_groups, page_manage_posts). Click “Generate Access Token” to generate an access token in order to save the permissions settings. Permissions are saved successfully and a new access token has been generated. Now select your page from the list Send the GET request to get the page name and ID to ensure the […]
