What is the Internet Protocol? The Internet Protocol is designed to implement a uniform system of addresses on all of the Internet-connected computers everywhere and to make it possible for packets to travel from one end of the Internet to the other. You may know it better as the “IP” in TCP/IP. There are various categories of internet protocols. These protocols are created to serve the needs of different types of data communication between different computers on the internet. Why use Python to interact with internet protocols? Python has extensive built-in modules to handle each of these communication scenarios. The methods and functions in these modules can do the simplest job of just validating a URL or also the complex job of handling the cookies and sessions. Because these models are built-in modules, no further installations are required. Read these articles, to see “How Python is Powerful for Dealing with Various Scenarios”: Delphi adds powerful GUI features and functionalities to Python In this tutorial, we’ll build Windows Apps with extensive Internet Protocols and Supports capabilities by integrating Python’s Internet Protocols and Supports libraries with Embarcadero’s Delphi, using Python4Delphi (P4D). P4D empowers Python users with Delphi’s award-winning VCL functionalities for Windows which enables us to build native Windows apps 5x faster. This integration enables us to create a modern GUI with the Windows 10 look or style and responsive controls for our Python applications. Python4Delphi also comes with an extensive range of demos, use cases, and tutorials. We’re going to cover the following… How to use http, ipaddress, smtplib, urllib, uuid, webbrowser, and wsgiref Python libraries to interact with Internet Protocols and Supports All of them would be integrated with Python4Delphi to create Windows Apps with Internet Protocols and Support capabilities. Prerequisites Before we begin to work, download and install the latest Python for your platform. Follow the Python4Delphi installation instructions mentioned here. Alternatively, you can check out the easy instructions found in the Getting Started With Python4Delphi video by Jim McKeeth. Most of the modules above require the presence of the system-dependent module socket, which is currently built-in support on most popular platforms. Getting started with Python4Delphi First, open and run our Python GUI using project Demo1 from Python4Delphi with RAD Studio. Then insert the script into the lower Memo, click the Execute button, and get the result in the upper Memo. You can find the Demo1 source on GitHub. The behind the scene details of how Delphi manages to run your Python code in this amazing Python GUI can be found at this link. Open Demo01.dproj. 1. How to use the Python http package? We can use the http package for working with the HyperText Transfer Protocol. http is a collection of these modules: http.client is a low-level HTTP protocol client; for high-level URL opening use urllib.request http.server contains basic HTTP server classes based on socket server http.cookies has utilities for implementing state management with cookies http.cookiejar provides persistence of cookies http is also a module that defines a number of HTTP status codes and associated messages through the http.HTTPStatus. The following is a code example of http package to learn about HTTP Statuses (run this inside the lower Memo of Python4Delphi Demo01 GUI): from http import HTTPStatus print(HTTPStatus.OK) print(HTTPStatus.OK == 200) print(HTTPStatus.OK.value) print(HTTPStatus.OK.phrase) print(HTTPStatus.OK.description) print(list(HTTPStatus)) from http import […]

We are pleased to announce that the next version of Delphi, C++Builder and RAD Studio will be version 11. This is currently in the works and we plan to release it later this year. Moving to Version 11 A few years back, Embarcadero decided to match the version number of the two primary desktop operating systems we target (Windows 10 and OS X, later renamed macOS 10) with a series of RAD Studio 10.x releases: 10 “Seattle”, 10.1 “Berlin”, 10.2 “Tokyo”, 10.3 “Rio”, and 10.4 “Sydney”. In light of the recent changes in macOS versioning (currently at version 11) and Microsoft’s recent announcement of a coming Windows 11 version, we have decided to change our product numbering scheme accordingly. Windows, in particular, remains a key target for us, with the best library to build Windows client UI applications, our own VCL and we want to underline this strong connection. Therefore, the next major release of RAD Studio, Delphi and C++ Builder, originally expected to be 10.5, is going to be version 11. We expect it to be followed by minor updates with version numbers like 11.x and a future new major release called 12. RAD Studio 11 will build on the great features introduced in RAD Studio 10.4 series and will add new features and enhancements throughout the product, with particular focus to the Integrated Development Environment (or IDE), that is, the RAD Studio application itself. The Olympus Beta Program At the same time of this version number announcement, we are pleased to invite all of our RAD Studio customers with an active update subscription to the NDA beta program for Embarcadero’s Delphi, C++Builder, and RAD Studio 11, codenamed “Olympus”. Differently from the past, there are two separate beta programs, one for Premium Update Subscription customers and the second for all other Update Subscription Customers (the beta program, in fact, is reserved to customers with an active subscription). The Premium beta program includes as an extra benefit an online forum for beta-related feedback and discussion, where you can engage with product experts, product managers, and fellow beta testers. How to join for Premium Subscription Customers Premium subscription customers have received an email invite (sent to the primary contact for their subscription) and can join by adding their registration email address to a specific form included in the communication. If you haven’t received it and want to join the Premium beta, you can reach out to your sales representative or reseller partner. How to join for regular Subscription Customers: We have also sent an email to all subscription customers, indigent them to participate in the regular beta. In case you haven’t received it, please provide your name and the email address associated with your Update Subscription (the email you used to register the product) using this form by Friday, July 16, 2021. For both groups, once you’ve provided your email address, you will receive a follow-up email later in July, with a link to electronically sign the Olympus Beta NDA. After signing the NDA, you will be provided with the information needed to participate in the beta. Please note that we recommend against installing beta versions on a production machine. Join the Subscription to Join the Beta Not currently on subscription but interested in joining the Olympus beta to get a […]

The weather is hot in the northern hemisphere, so that means it is time for the annual Embarcadero sponsored Learn to Code Summer Camp! Our Summer Camps and Boot Camps have been a huge hit in previous years. This is your chance to gather online and learn from best trainers. The 2021 Summer Camp run for the week of Monday, July 26 through Friday, July 30th, 2021. That is one full week of free online training from the best trainers on the best development tools. This year we are expanding the offering: With the addition of PyScripter as a Free Tool sponsored by Embarcadero, we are now including classes on learning Python along with Delphi/Object Pascal, C++, SQL and web technologies like HTML and JavaScript. Beyond the basics of learning the languages, we plan to cover topics including: mobile development, Android, iOS, Linux server, Windows Desktop, game development, web development, databases, and more! Let the debates on if SQL and HTML are “programming languages” commence! The Learn to Code Summer Camp is all about learning to program. The content is aimed at people with little to no previous programming experience, or maybe someone who wants to pick up a new language. If that sounds like you, then register as a student. If instead you have some experience you would like to share, then sign-up as a volunteer! Even if you don’t know what you would like to cover yet, but would like to be involved, we would love to have your help! Stay tuned to this page for more information!

InterBase is a robust, flexible and powerful database with great scaling capabilities and functionality that allows you or your clients to take data offline securely. When you first start with any database software, it can be a little intimidating. Learning about all of the different features and functionality, how to use those features, and what to do when you have developed your applications can be overwhelming. So, if you’re just starting out with InterBase or used to be an InterBase user, now is the time to check out this webinar [Stay tuned for the link to the replay!] We discussed getting started, developing with InterBase databases and applications as well as some of the things you can do to manage your InterBase instances. Hit the Ground Running Slide deck Some Q&A responses What version of InterBase is included in RAD Studio? All versions of RAD Studio have access to the Developer Edition of InterBase while Professional Edition, you have access to IBLite Enterprise or Architect editions have IBToGo. This version of IBToGo is for mobile (Android and iOS) deployments only. How is InterBase ToGo used? For a single user or can multiple users access the database? InterBase ToGo is deployed in a single user environment. The database file is distributed to individual users, who have access to the data whether they use a mobile device or a desktop application. What are some of the advantages of ToGo over SQLite I’m not a Delphi developer, can I still download the IBConsole/InterBase Developer edition? Yes, you can get the InterBase Developer Edition download from our website. What resources are available for InterBase 2020? While there are currently no books available on InterBase 2020, we have our InterBase DocWiki that provide detailed information and sample code for working with InterBase.

When it comes to computer games it’s often the most simple ideas which are the most addictive and compelling. Hitting on a winning combination of simplicity but in a way which engages the game player so well they keep wanting more is like writing that elusive musical chorus; the ear worm, the thing which feeds some deep pleasure center of our distractible brains. Software developers are the kindred spirits of musical maestros If you can come up with that must-have app formula it’s a golden moment and extremely satisfying for a software developer. After all, we want our programs and apps to be used and, even better, we want them to be loved. We developers are an odd bunch but the music industry is also full of that same kind of slightly left-field thinking. Like a song writer or musician harnesses that creative side of mankind while working within the science and rules of the musical keys, developers turn ideas into apps while they corral the capabilities and restrictions of the hardware device and operating system. Programming is an art…and a science. Xpand takes a simple idea and executes it beautifully The rules of Xpand are simple; conquer the board or leave opponent out of moves by filling fields until they expand to nearby fields where the opposition become overwhelmed. The gameplay allows you, the player, to pit your skills against a custom-written AI opponent who plays a surprisingly strong strategic game! The game uses touch to control where you place ’tiles’ or discs. Like similar games such as Reversi and checkers or draughts there are not a whole load of different moves. The skill is in the strategic choosing of cells or squares and anticipating your opponent’s next steps. There’s a great twist where ‘chain reactions’ are created and corner fields hold a special significance which becomes clear as you play along. You can choose to play against the computer/device’s AI opponent or against a real live friend. Another great game written using RAD Studio Delphi Xpand is just one of an increasingly substantial cohort of mobile games written using Delphi and the powerful cross-platform capabilities of the FireMonkey FMX framework to work its magic. Reusing the same code base the winning combination of FireMonkey and Delphi allows US developer Davor and Robi to offer Xpand on both iOS and Android devices with little or no code changes. Delphi is pretty much the original low code platform and it continues to meet this challenge even on today’s constantly xpanding range of platforms, devices and operating systems.

The versatility and reliability of Delphi along with its ease of use and cross-platform capabilities means there are apps everywhere which are written using it. We’ve seen everything from fun games like the hilarious Good Cat Bad Cat to life or death utilities like the impressive E6B flight computer. RAD Studio’s powerful development environment when coupled with the comprehensive run time libraries and component ecosystem means the tough jobs are made easier and the fun apps can be fun to write too with the drudge of ‘scaffold’ code of other computer programming languages being almost entirely avoided. There are very few systems out there which really do mean “low code” in the way Delphi does and an even smaller selection of those are able to even get close to the cross-platform capabilities of Delphi’s FireMonkey FMX framework which lets developers write apps with apps able to run on Microsoft Windows, macOS, iOS, Android and Linux. Not only that, the cross platform apps achieve this with very few changes to the code. Score Note uses Delphi to do the hard work Keeping score is one of those task which can be made easier and perhaps even more fun by using an app to do it. Are you still looking for pen and paper to record your score while the game is in progress? With the Score Note app you can stop juggling messy pieces of paper or smudging chalk boards. Instead you can use your mobile device to keep score and leave the pen behind. The game score will be permanently saved (unless you delete it manually). You can save scores of multiple games in progress at the same time. Written by developer Max Lin Score Note is a great way to bring the art of score-keeping into the 21st century.
