New server administration commands
4D continues to deliver features to help you create your own applications to monitor your servers. From programmatically retrieving information about sessions, processes, and the application server, to getting information about the web server.
Having already provided you commands to read about statuses, 4D v17 R4 now gives you the ability to change statuses. You can now create your own administration interfaces as dialogs on the server, client, or even as HTML pages for web access. It’s up to you. These commands allow you to perform the same actions as the standard 4D administration interface. For example, you can send a message to your users to notify them of scheduled maintenance, or block new connections to the application server while you perform an operation on it.
4D Write Pro: WP commands and beyond
We’ve received comments on the forum and TAOW about features that previously existed in the 4D Write plug-in but seem to be missing in 4D Write Pro. Yet, they’ve been available for a long time!
In this blog post, we’ll go through a list of existing abilities in 4D Write Pro that seem to have gone unnoticed. In another words, 4D Write Pro features you didn’t know existed.
After all, 4D Write Pro is not limited to WP commands!
A component to export the structure file
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.
Better documents with two new attributes
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.
Page layout in 4D Write Pro
When creating a 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.
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.
Manage sections with code in a 4D Write Pro document
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!
Text files from your structure file
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.
Change the properties of several methods at once by code
We know that sometimes you want to change the properties of multiple methods without having to open the property dialog for each method.
For example, you want to set all methods to “Can be run in preemptive mode” status, then compile your database. So with compilation errors, you get an overview of the methods to modify to be preemptive.
Using the METHOD GET NAMES command to retrieve the list of methods from your database, and then using the METHOD SET ATTRIBUTES command to modify the attributes, lets you modify them all at the same time!
