In 4D v17 R6, ORDA queries are becoming increasingly more powerful and concise. This blog post is for those of you who need more sophisticated search criteria than just a simple syntax like “name = Smith‘”. With this R-release, you can use any project method or 4D expression in the query() member method by using formulas.
What better way to explain this feature than with an example? Let’s dig into the details.
With 4D v17 R5, we’ve improved the debug logs by adding methods and allowing each process to be traced independently. With this R-release, we’ve gone a step further by shipping a debug logs analyzer tool to help you monitor process execution. You’ll be able to see which processes are the most consuming, the call chain with the corresponding running time, and much more.
CRUD (Create, Read, Update, Delete), a pillar of database actions, makes its debut in 4D for iOS in 4D v17 R6.
In 4D v17 R5, we introduced actions so you could better interact with your 4D for iOS apps. This included the ability to create actions to execute 4D code from your iOS apps. Things are getting even more interesting with this R-release, now you can easily manage and edit your app content using parameters.
If you need to read or write hundreds of different values or formulas, you can do it faster, easier, and at the same time by using collections. New commands are available for this: VP SET VALUES, VP Get values, VP SET FORMULAS, and VP Get formulas.
When programming an application, you may need to know where you are in your code, especially when one method calls other methods, which may then call other methods. That’s why it’s very helpful to see the chain of methods, or the call chain, during the debugging process. For this, 4D v17 R6 provides the new Get call chain command to give you an insight into the executed code. Now you won’t have to worry about getting lost anymore!
Prior to 4D v17 R5, you may have discovered upon opening your 4D Write Pro document that the displayed font is not what it is supposed to be! If the document contains fonts which are not on your computer, 4D automatically replaced them with Times New Roman. However, since font preference is a matter of individual choice, this R-release gives you the ability to choose the replacement fonts!
Using ORDA to access large tables (especially those with relations) in Client/Server mode has been greatly enhanced. With 4D v17 R5, you’ll see 2-3xs improved LAN performance and up to 30xs faster WAN performance. And best of all – there’s no need to change anything in your code, it’s all automatic. Interesting, isn’t it? Well, let’s delve into the details.
As a 4D developer, you may have already activated the debug log to troubleshoot problems. 4D v17 R5 introduces several improvements to help you analyze these files, such as logging only the current process and logging calls to member methods (collection or object methods).
If you still need to communicate with old devices that don’t support Unicode, this blog post is for you! Keep reading because with 4D v17 R5, you can send emails in legacy encodings (ISO-2022-JP for Japanese or ISO-8859-1 for Western European).
We’re thrilled to announce that support for actions in 4D for iOS is available with 4D v17 R5! This feature allows you to enjoy more interactivity with your mobile app. For example, you can set a task as completed or finished, or flag events to be checked. All with the swipe of a finger, or by simply selecting an action from a menu.
