Thanks to 4D v17 R3, you can export your structure file in multiple text files. For example, with only a few lines of code you can create a copy of your database every morning. You can use this to keep track of the history or to send your database to a colleague and see the changes when they’re done working on it.
We provide you a ready-to-use component with only two methods: one to configure the data to be exported, and the other to export your database.
To produce a nice document, you need to respect some typesetting rules and fundamentals. For example, the grammar, spelling, and structure of your document shows the quality of your text. One of these rules concerns the distribution of paragraphs and tables over multiple pages.
4D Write Pro offers you two options to manage paragraph distribution:
- Avoid page break inside paragraphs or tables, and
- Avoid widows and orphans for paragraphs or tables.
Let’s dig into more details.
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 …
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.
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.
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!
Want a different background per section? Or maybe a different margin per section? How about a different number of columns per section? Want to do all this with code?
With 4D v17 R3, you can manipulate sections with code to create complex and beautiful documents!
Developing an application is often a very collaborative job, involving many people. In this case, you may want store your development in a source control repository, or have a history of the work done during the day, or send your database to a colleague and see the changes when they’re done working on it.
All of the above scenarios are now possible! Beginning with v17 R3, you can export the .4DB file into multiple text files. This offers you many new possibilities.
