Improving databases tests
As a developer, you’re aware that improving the quality of your developments is often based on unit tests. In order to launch these tests, developers and QA teams need tools to launch 4D databases in different modes (single user / client-server) and distinct environments (Macintosh / Windows).
4D products can already be launched using command line parameters to allow automatic testing or deployment. What if you want to create your own update mechanism or you need to handle a server farm with hundreds of 4D Servers running? Maybe you want to specify which database file to use – or pass parameters on launch …
Use your own icons in 4D for iOS
As we’ve seen in the last two 4D for iOS blog posts (data formatters and the creation of custom templates), 4D for iOS is becoming more feature-rich with each version. This provides more options when building your 4D for iOS applications. In this blog post, we’ll look at how you can use your own icons for more personalized apps.
Page layout in 4D Write Pro
When creating a 4D Write Pro document, you need to define the page size, orientation, and margins. Starting with v17 R3, you can do all this by programming. And for that, new attributes are at your disposal.
Get info about the running application
4D v17 R3 takes your database analysis a step further by enabling you to create a customized server administration dialog. Following the ability to retrieve information about users & processes, getting all runtime information about 4D Web server, getting details about the active license, and getting all of the hardware and system details, you now also have the ability to retrieve the activity and network configuration of the running database.
Do you need to know on which IP address and port the database is listening, if communications between the client and the server are encrypted, or if the legacy network layer is used? Just call the new command, Get application info. And that’s not all! This command also returns information about the database such as: the amount of CPU used, the time since its been started, and the list goes on.
Convert classic 4D forms to dynamic forms
Your forms may need to be changed depending on your customer or user needs. For example, the color black might be perfect for one user but not so much for another user (who sees blue as the ultimate perfection). Luckily, dynamic forms (introduced with 4D v16 R6) are here to help you handle your users’ preferences. But rewriting an existing form to a dynamic form could be a difficult task, and it’s not always easy to start with a blank page. Ideally, it’d be best to have a draft that can be modified and improved. With 4D v17 R3, it’s now possible to easily convert a classic 4D form (stored in .4DB file) to a dynamic form.
Create headers and footers with code in a 4D Write Pro document
Since v16 R5, it’s been possible to access and modify an existing header and footer by programming. If you want to add a header and footer to your 4D Write Pro document, you use a template to do so!
If you’re not a fan of templates, good news! With 4D v17 R3, you can create a header and a footer by programming for a given section.
How to create 4D for iOS form templates
Work with .xlsx documents using 4D View Pro
Do you need to open a Microsoft Excel document directly in your 4D View Pro area, or convert a 4D View Pro document to Microsoft Excel format to send it to a customer? It’s now possible! Thanks to this feature, your 4D business applications have taken a further step towards better compatibility with the MS Office environment.
Data formatters with 4D for iOS
Write your own methods for objects
A new command is at your disposal allowing you to use formulas in your code. You can now encapsulate them in objects and call them when needed. There’s no more need to write your code as text. Now you can just pass your formula in your command and that’s it! This is a great addition, since your code isn’t text, you can benefit from Syntax highlighting and all the other advanced functionalities of the code editor!
