Building evaluation applications

In previous versions of 4D, developers could request evaluation licenses for development purposes, but providing end users with evaluation versions of built applications—whether standalone or client/server—was challenging or even impossible.

Starting with 4D 20.7 and 20 R8, you can now create evaluation versions of your applications. When a user runs an evaluation application for the first time on a new machine, it will automatically contact a 4D service to obtain a 14-day evaluation license—without any manual action required from the user.

This blog post will guide you through the process of creating an evaluation version of your application for demo purposes.

Master HTTP Requests with 4D Request Handlers

In today’s web-driven world, servers process an overwhelming number of requests. Efficiently analyzing, counting, interpreting, and rerouting these requests is essential, especially when applying MVC principles.

In 4D 20 R8, with the introduction of HTTP Request Handlers on the 4D HTTP Server, you can define accurately which business logic you want to trigger regarding specific URLs patterns.

Main advantages of this feature are:

  • Offering more granularity in implementing the code handling received requests. This business logic can be split in several classes. Forget extensive Case of statements in the On Web Connection database method.
  • Allowing a redirection on a Qodly page which opens up new perspectives to extend 4D application on the web

 

This powerful feature unlocks many possibilities, as detailed below. Keep reading to learn more and work with concrete examples.

New class to perform TCP connections

With the release of 4D 20 R8, a game-changing feature has arrived:: the TCPConnection class. This modern class leverages object-oriented syntax and supports asynchronous network connection handling, providing a fresh and powerful alternative to the 4D Internet Commands. Using TCPConnection, you can connect to virtually anything—whether it’s servers, printers, cash registers, or industrial devices—making it a versatile tool for handling unique networking requirements.

In this release, the TCP client functionality is available, allowing you to connect to external servers and seamlessly exchange data.

Debugging 4D Code Directly in Visual Studio Code

For Visual Studio Code users working with 4D, a new extension called 4D-Debugger that works with 4D 20 R8 is now available.

The new 4D-Debugger extension brings powerful new debugging capabilities to Visual Studio Code, expanding on the features of the 4D-Analyzer introduced earlier. With this extension, you can set breakpoints, step through 4D code, and inspect variables from the Visual Studio Code interface. This tool integrates seamlessly, simplifying the debugging process and making VS Code a more versatile workspace for 4D projects.

Notarization on macOS: Changes to Component Structure

The macOS notarization process continues to evolve. Unfortunately, the internal structure of 4D components designed with 4D v11—intended to enable cross-platform compatibility—no longer meets the requirements introduced by Apple for Silicon-based Macs, making notarizing components increasingly challenging.

To simplify the deployment process, we have updated the component structure starting with 4D 20 R8. This new folder structure makes notarization and deployment as straightforward as deploying an application. However, there is an important caveat: the updated structure is not compatible with older versions of 4D (e.g., 4D 20 R7 and earlier), while older components will remain compatible with newer versions of 4D.

The Build4D component has also been updated to reflect the new structure. When building components, be cautious and ensure you are using the correct version of Build4D.

Important Reminder: Components built with 4D 20 R7 or earlier may encounter errors during notarization. The recommended solution is to update to 4D 20 R8.

Enhancing the Debugging Experience

Debugging plays a vital role in any development process, and improving the debugger’s functionality and usability can significantly enhance a developer’s productivity. From 4D 20 R8, 4D has introduced several improvements to its debugger and remote debugger. These updates focus on saving user-defined settings, making managing and reusing expressions easier, and redesigning the overall interface.
