For you who works with COM Port Applications on linux, this is the most easy and fast way to connect, write and read info. Using  COMPORT for linux you can do it within literally few minutes, you just need to download the library and add it on your project, and this is it. First of all you need to prepare your linux machine to deploy your Console application from a Windows. On this example I’m using a Windows host running VM VirtualBox with Ubuntu. Installing Development Packages To install the development packages on Ubuntu: Right-click your desktop and select Open Terminal. To upgrade the packages you have already installed , type sudo apt update && sudo apt upgrade && sudo apt dist-upgrade in the terminal. Type your user password and press Enter Wait until prompted to agree to the package upgrade operation. Type Y and press Enter Wait until the package upgrade operation is complete. It may take a few minutes to complete. To add the development packages, type sudo apt install joe wget p7zip-full curl openssh-server build-essential zlib1g-dev libcurl4-gnutls-dev libncurses5 in the terminal. Type your user password and press Enter Wait until prompted to agree to the package installation operation. Type Y and press Enter Wait until the pacjage installation operation is complete. It may take a few minutes to complete. Preparing Your Linux Machine To create Linux applications, you need to add a virtual machine PAServer: Find the LinuxPAServer21.0.tar.gz file in the following location: C:Program Files (x86)EmbarcaderoStudio21.0PAServerLinuxPAServer21.0.tar.gz Unpack the LinuxPAServer21.0.tar.gz file. If needed Install the zlib library to your Ubuntu machine with the following command: sudo apt-get install zlib1g-dev Open the current dir on terminal and run it using ./paserver Now that the Linux Machine is ready lets download and use the COMPORT Library. Preparing Your Delphi application Creating a Connection Profile On the Tools > Options > Environment Options > Connection Profile Manager page, click the Add button. The Create a Connection Profile wizard opens On the Profile information page, enter the following: In the Profile name field, enter the needed name. In the Platform field, click the 64-bit Linux platform. Click Next. On the Remote machine information page, enter the following: In the Remote machine field, enter the IP address or Machine name. Click Test Connection to check if the values are valid. Adding the Installed SDK to RAD Studio On the Tools > Options > Environment Options > SDK Manager page, click the Add button. In the Add a New SDK dialog, enter the following: In the Select a platform field, click 64-bit Linux. In the Select a profile to connect, select a created profile from the drop-down list. In the Select an SDK version field, the name of the SDK that you just installed will automatically appear. If you have not installed SDK previously, you can do it on this step. If you have already installed SDK, move on to the next step. Download the package from WINSOFT, unzip it and open the demo application with Delphi, after that just add the library path on the project properties. The entire Tutorial for this process is here (available for Red Hat too).

Introduction OBR (Optical Barcode recognition) component for Firemonkey supports Windows, macOS, iOS and Android. Its main purpose is to decode QR code and Barcode images. In the below video you can check the steps to install the firemonkey component for OBR. The installation steps differs to the one for the OBR firemonkey library, it is actually easier. 2. Components in the Demo and what they do There are two panels. One is at the top, containing the button for the picture choise. In the middle there is a Scroll box component (for scrolling) and a Timage component inside it for the chosen picture. At the bottom there is another panel again, containing the TMemo component . All combined they create the windows that shows up with button, image and text at the bottom.     Clicking on the button executes the TOpenPictureDialog component which opens a dialog for selecting a picture. The selected picture is loaded in an TImage component and shown on the main empty window. Clicking on the button executes the TOpenPictureDialog component which opens a dialog for selecting a picture. The selected picture is loaded in an TImage component and shown on the main empty window. with OpenDialog do if Execute then begin Memo.Lines.Clear; ImageControl.Bitmap.LoadFromFile(FileName); with OpenDialog do     if Execute then     begin       Memo.Lines.Clear;       ImageControl.Bitmap.LoadFromFile(FileName); Then the selected picture is decoded using the TBarcodeDecoder  object (the ‘scanner’) and the results is filled into the TDecodeResults list as it follows: with TBarcodeDecoder.Create do try Barcodes := Decode(ImageControl.Bitmap); with TBarcodeDecoder.Create do       try         Barcodes := Decode(ImageControl.Bitmap); If code is detected by the TBarcodeDecoder  object, the result is stored in the TDecodeResults list, named as Barcodes. With FOR cycle we check the list and its items of what they have stored before. The item of the TDecodeResults list contains FormatName and Text (which is the doceded text). You can see in the below code: for I := 0 to Length(Barcodes) – 1 do Memo.Lines.Append(Barcodes[I].FormatName + ‘: ‘ + Barcodes[I].Text); for I := 0 to Length(Barcodes) – 1 do             Memo.Lines.Append(Barcodes[I].FormatName + ‘: ‘ + Barcodes[I].Text); You can download the Demo with the component from the link below: https://winsoft.sk/fobr.htm

Alien Invasion is a classic arcade-style game which features a grid of aliens that move in sync back and forth across the screen. They fire projectiles at the player who is at the bottom of the screen. On each trip back and forth across the screen, they start moving faster and faster. There are four shields near the bottom of the screen that the player can hide behind but they have a limited number of hits they can take before each shield is exhausted. The player can only move back and forth at the bottom of the screen and fire projectiles upward. What you can learn from this complete Alien Invasion game sample: Game Design Basics Game Development App Tethering Collision Detection Building Game Loops Working With Sounds/Music Cross-Platform Development Patterns TMotionSensor TBitmapListAnimation You can download this game sample from GetIt easily With RAD Studio, game development is absolutely easy to start.

MongoDB is a document database, which means it stores data in JSON-like documents, the most natural way to think about data, and is much more expressive and powerful than the traditional row/column model. How about connecting with MongoDB and exploring the available databases and data using FireDAC components in your Application. Don’t know where to start? This post will guide you to do that. MongoDB.Explore Sample App shows how to connect to available MongoDB Databases, access to its ListCollections, and populate to the grid using MongoDB API wrapper class. You can find Delphi and C++ code samples in GitHub Repositories. Search by name into the samples repositories according to your RAD Studio version. Components used in MangoDB.Explore Sample App: TFDPhysMongoDriverLink: To link the MongoDB driver to an application and set it up. In general, it is enough to only include the FireDAC.Phys.MongoDB unit into your application uses a clause. The TFDPhysMongoDriverLink component can be used to specify: The VendorHome – the MongoDB installation root folder. The VendorLib – the name and the optional path to the MongoDB client library. TFDConnection: To establish a connection to a DBMS and to manage associated datasets. TFDMongoDataset: Used to attach a dataset to an existing MongoDB cursor. This class allows you to attach the dataset to an existing MongoDB cursor. You can get the cursor from various MongoDB API wrapping class methods, such as TMongoDatabase.ListCollections.To open a dataset, assign a cursor to the Cursor property and call the Open method. TFDMongoQuery: The TFDMongoQuery class is used to execute a MongoDB query. You can specify a query in one of the following ways: Using the QProject, QMatch, and QSort properties at design-time or run-time. Using the Query Builder provided by the Query property at run-time. Use TDataSource to populate the fetched data to TDBGrid. Implementation Details: You can find the MongoDB Explore Demo sample project at: Object PascalDatabaseFireDACSamplesDBMS SpecificMongoDBMongo_Explore.dproj. Before running this, as a preliminary step, we need to have a MongoDB Server is running and accessible from your host. For Details, See Connect to MongoDB Database. Check the below screen for listing the databases in the MongoDB server. Upon changing the database, its list collections changes. This screen Demonstrates the “restaurants” collection of the “test” database is provisioned with test data.

It is already November—time flies these days. Despite the global pandemic, we keep charging ahead. As developers are getting more used to working from home (and some love it), we see more projects picking up, which is exciting. I am especially thrilled that there are more and more public Delphi projects on GitHub, and related discussions on popular platforms, such as Stack Overflow and Reddit, are growing, though not as quickly. I know that we have our own more proprietary ones, which are great, but the more Delphi we put out there, the better! My themes lately have been simple: Develop brilliant code. Share it. Inspire existing and new Delphi developers. Have you checked any of these boxes lately? There are about 8K Delphi projects on GitHub. Some 500K+ developers know Delphi, and at least 200-300K are actively developing with it. You do the math! We recently released Bold for Delphi open source to help contribute to the community, and a fantastic group of developers is now working on the project. Embarcadero is just getting started with open source projects, so be on the lookout for more! Here are some highlights of our current efforts: 10.4 was an essential release with over 1,000 enhancements and quality fixes. Many of its features were welcomed by both large companies and individual developers. 10.4.1 is a stable and robust version, featuring a faster implementation of Delphi Code Insight based on Language Server Protocol, VCL styles that work great with High-DPI and 4K monitors, extended Apple platforms, and API coverage. It also includes a much improved GetIt package manager and many other features. 10.4.1 adds over 800 quality improvements, including 500+ for issues publicly reported on the Quality Portal site. 10.4.2 Beta is also kicking off soon for Update Subscription customers. It is a great time to upgrade! With almost 4000 people registered, this was our biggest annual Delphi event. If you missed the live sessions, register now to catch the replays. This year we included many expert panels, including with some of Delphi’s lead architects, a massive hit with everyone! Join and enjoy presentations from thought leaders and check out some of the great perks and discounts available. One of our goals with DelphiCon was to simplify the format compared to previous CodeRage events and we hope you enjoyed it. We are always looking for ways to improve, and your feedback is valuable. By popular demand, a dedicated C++ event is in the works for the spring. Product management recently updated the RAD Studio roadmap for November 2020. Always great to see what the plans are for the future, and read the commentary from product management around these plans. These roadmaps are based on the direction of the industry, and the feedback we receive from you, our users. Check out the roadmap, leave your feedback, and file feature requests on Quality Portal. We realize that budgets are tight these days and want to make working with the latest releases more economical. We have a number of attractive global promotions to fit different needs. We have enhanced the Architect SKU to include a lot of value-added products, from Ext JS and Ranorex licenses to the expanded use of InterBase and RAD Server. If you are looking for the best dollar deal, that is clearly […]

We know how to do Multithreading in Delphi. How about a simple python script that performs threading in Python and runs the script in the Delphi application? This brings the advantage of using existing multithreaded or new python scripts in your Delphi application. This post guide you to do that with the Python4Delphi Sample app. You can also use Python4Delphi with C++Builder. Python4Delphi Demo22 Sample App shows how to create a Python script in Delphi Application which demonstrates creating thread and output the result in windows console, passing arguments in the command line. You can find the Demo22 source on GitHub. Prerequisites: Download and install the latest Python for your platform. Follow the Python4Delphi installation instructions mentioned here. Alternatively, you can check out this video Getting started with Python4Delphi. Components used in Python4Delphi Demo22 App: TPythonEngine: A collection of relatively low-level routines for communicating with Python, creating Python types in Delphi, etc. It’s a singleton class. You can find the Python4Delphi Demo22 sample project from the extracted GitHub repository ..Python4DelphiDemosDemo22.dproj. Open this project in RAD Studio 10.4.1 and run the application. Implementation Details: PythonEngine1 provides the connection to Python or rather the Python API. This project uses Python3.9 which can be seen in TPythonEngine DllName property. It uses a Python Script file threading_test.py where the below list of modules was used. threading: This module constructs higher-level threading interfaces on top of the lower level _thread module.  collections: This module implements specialized container datatypes providing alternatives to Python’s general-purpose built-in containers, dict, list, set, and tuple. In this sample, deque is used. time: This module provides various time-related functions. threading_test.py contains, ProducerThread, ConsumerThread, BoundedQueue class within the function _test. Memo1, used for providing the Python Script to execute. On Clicking Execute Button the below code executes the python script. procedure TForm1.Button1Click(Sender: TObject); begin PythonEngine1.ExecStrings( Memo1.Lines ); end; procedure TForm1.Button1Click(Sender: TObject); begin   PythonEngine1.ExecStrings( Memo1.Lines ); end; The script below is executed which will opens a window console, create threads put in a queue and execute one after other. import threading_test import sys # the following is needed to use the newly allocated console! sys.stdout = sys.stderr= open(‘CONOUT$’, ‘wt’) try: count = int(sys.argv[1]) except: count = 3 for i in range(count): print (“**** Pass”, i) threading_test._test() print (“**** Done.”) import threading_test   import sys # the following is needed to use the newly allocated console! sys.stdout = sys.stderr= open(‘CONOUT$’, ‘wt’)   try:   count = int(sys.argv[1]) except:   count = 3   for i in range(count):   print (“**** Pass”, i)   threading_test._test() print (“**** Done.”) Head over and check out the open source Python4Delphi project which makes it easy to build Python GUIs for Windows with Delphi.

Miyazaki Prefectural Saitohara Archaeological Museum has built an app for smartphones, “Saitohara Archaeological Expo Navi,” which provides navigation in the museum, guidance on exhibits, etc. in multiple languages ​​using solutions provided by Embarcadero and Marubeni Information Systems. did. This solution consists of a power-saving beacon that emits radio waves (using “rapiNAVI Air2” manufactured by Marubeni Information Systems) and Embarcadero’s software development function “Beacon Fence” that detects the position using this beacon. At the Saitohara Archaeological Museum, you can use the in-house navigation system “Saitohara Archaeological Expo Navi” that utilizes beacons. With this system, you can check the current location of the museum on your smartphone, and read the explanation of the exhibits in front of you in four languages: Japanese, English, Chinese, and Korean. In this session, we will introduce how this system was built at the museum, along with an overview of the system and the features of RAD Studio / Delphi + BeaconFence used.

Developer Zudomon (Nick Pützer) has been building an impressive procedural game called StoneQuest and 3D engine in Delphi. He has put in over 12,000 hours since 2011 building the engine and game. The whole game and content is less than 15MB in size! One of the goals of the developer is for him to build it entirely himself in Delphi. The current gameplay is reminiscent of Minecraft. According to the developer “I use a lot of procedural content. All the models are created by code only. This mean, later I can do many different models from them! My engine is able to spread microgeometry over the world, real tiny 3d models. Every grass blade and clover plant is real and interact with players. Every cube face of the voxel world has it’s own texture. I only have a few procedural textures yet. They doesn’t repeat. There are dynamic volumetric 3d clouds. And volumetric fog in the valley, where sun rays shine through the trees. For me atmospheric and immersion is a very important thing.” The project is still in active development but you can download and play it in it’s current state. At this point it is a work of art which is beautiful to behold. Website https://stonequest.de/ Ready to get started with the latest RAD Studio version?
