With 4D v17 R4, embedding and displaying filtered content in your 4D for iOS app is a piece of cake! With this R-release, you’ll be able to filter the data to be displayed in your mobile app.
By now, you should be familiar with the WP Get position command. At the very least you’ve read about it in this blog post. Introduced with v17, it helps you get information about the location of elements within your documents.
4D v17 R4 spices things up … now, it also returns coordinates!
Preemptive processes are very useful for performing extensive calculations in parallel, using all of the cores in your CPU, but sometimes you need to delegate tasks to a cooperative process (e.g., using a non preemptive command). With the New signal command, you can pause a process and wait for the response from another process!
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.
With 4D v17 R3, we introduced basic data formatters for dates, percentage, time, etc. 4D v17 R4 takes things a step further by providing you the ability to create your own data formatters and use them directly from the Project Editor.
We’re pleased to announce that a new feature has been added to 4D Write Pro. In page mode, a vertical ruler can be displayed on the left side of the page! This lets you graphically manage the vertical margins. And if your document contains headers or footers, the spaces between them and the body of your document can be modified easily thanks to this ruler.
The ability to interact with a document via programming is an important part of using 4D View Pro. Now you can fill your documents by programming. You can set data as labels, database fields, or formulas in your document. Of course, if you can set, you can get too! You can also retrieve cell formulas or values entered by your users.
4D v17 R4 brings new features to 4D View Pro and one of them is the creation of ranges with code.
First, you need to define a range object to manipulate your cells by programming. You can do this in 4D View Pro with the following new commands: VP Cell, VP Cells, VP Column, VP Row, VP All and VP Combine ranges.
Preemptive processes allow your applications to take full advantage of multi-core computers, resulting in faster responses to simultaneous requests. Beginning with 4D v17 R4, Begin SQL, End SQL, and the associated SQL statements used with an internal database are now preemptive compliant.
We know the importance of sending emails and common a task it has become in today’s applications. For example, imagine you’re in a business and you want to send an attractive email based on HTML with a few images or even a video, and attach a file to it (e.g., a purchase order or an invoice). And you want to do all of this with just a few lines of code. Code that is easy to write and understand. Well starting with 4D v17 R4, the previous scenario is now possible. That’s why we’ve enlarged the feature set related to emails.
