Fortifying Security: 4D Embraces OpenSSL 3.1
In an era where data security is paramount, updating security libraries is crucial.
4D v20 has taken a significant step forward by upgrading its OpenSSL library from version 1.1 to 3.1.
This advancement brings forth a multitude of advantages and improvements for 4D developers, enabling them to build applications that are not only highly secure but also exceptionally efficient.
Now, let’s explore these benefits in detail.
A Tool for 4D Code Execution in CLI
In the development industry, CI/CD has become a standard practice. With each code modification, automated actions such as testing, compilation, building, delivery, and sometimes deployment are generated to ensure the code is high quality and easily integrated into the existing system.
These actions require a tool to execute the necessary code. As 4D developers, we decided to provide a free tool that allows developers to execute elementary actions. This tool is called tool4d, and it streamlines the process of executing necessary actions within the 4D environment.
In this article, we will explore the functionalities of tool4d and how it can be used to enhance your development process.
Integrate your Own Administration Window for 4D Server
When deploying their applications, some developers want to customize the built-in 4D dialogs to fit their needs. It is especially true for the 4D Server Administration Window where they sometimes want some information and actions to be accessible only for their team and not for their customer administrators.
New VS Code Editor Features with 4D v20
As usual, a new release, new VS Code extension features for developers who want to view and edit code with this free editor.
4D v20 brings new capabilities to the Visual Studio Code editor through the 4D-Analyzer extension: Say hello to Document Syntax Checking, which will help the developer to type fewer mistakes, Code Folding and Indentation for a better look, and tool4d to allow faster LSP server starting.
PDF format for Print Previewing on Windows
PDF format is a viable alternative to XPS for print previewing on Windows, providing users with a more accessible option. Microsoft’s decision to make the XPS Viewer an optional Windows feature has caused issues for many users when deploying applications, resulting in end-users being unable to preview their printings. Although installing the free XPS Viewer is straightforward, some administrators are hesitant to install additional features, particularly on Remote Desktop environments.
Fortunately, 4D v20 now offers the option of using the PDF format for print previewing. Since almost all current Windows versions have either XPS or PDF pre-installed, end-users should no longer encounter issues with print previewing. This new option offers a more flexible and efficient solution that meets the needs of both end-users and administrators.
Catch errors everywhere
Error management is often a constraining part of development in all languages. In 4D, if you forget to call an error-handling method in a new process/worker or use components that don’t handle errors, the built-in 4D error dialog can appear to the final user. 4D developers would like to catch all errors in all contexts to avoid displaying this built-in 4D error dialog.
Let’s see how we can manage this behavior with 4D v19 R8.
VS Code Extension: Code Completion
A new release, a new VS Code extension feature.
4D v19 R8 brings a new capability to the Visual Studio Code editor through the 4D-Analyzer extension: Say hello to code completion.
VS Code: Go To Definition & Signature Help
4D v19 R6 brought the support of external source code editors (e.g., Visual Studio Code), allowing them to handle 4D code and provide them with standard functionalities such as syntax highlighting using the Visual Studio Code extension.
4Dv19 R7 brings two new capabilities: Go To Definition and Signature Help.
Share Local Resources Between Users with Windows Remote Desktop Services
This new feature improves the local resources management of 4D Client merged applications executed with Windows Remote Desktop Services. Lets’ see how.
Setting up code syntax highlighting using the Visual Studio Code extension
We recently talked about our new Visual Studio Code extension allowing VS Code to communicate with 4D for code management. The syntax highlighting was the first Language Server Protocol feature in 4D v19 R6. Let’s see how to customize your source code rendering.
