Multiple servers, one shared local resources
There may be times when you might need users to connect to many instances of the same merged server application. When this happens, the merged client application downloads as many local resources as the server connections. But if your server’s Resources folder is huge, this can be quite a drain on time, volume, and network! Fortunately, 4D v18 R5 has a solution for this scenario!
Multiple instances of merged server applications on the same machine
Hosting several 4D Server applications on the same machine is not unusual, especially for production and pre-production environments. But if your machine hosts merged server applications built with different 4D versions, which is the case if you use your pre-production server with the latest 4D version, you may encounter problems due to the shared 4D structure folder.
Let’s see how to resolve this issue.
Pro list box features are now FREE!
Interested in building list boxes that can automatically adapt the height of each row to its content so that the full text or picture can be displayed? What about using object arrays in columns (this allows entering and displaying various types of values in the rows of a single list box’s column).
These are very cool features, right? Previously, you needed to have a valid 4D View Pro license in order to use them. Well, not anymore!
4D v18 R4 lets you access these features for FREE! No additional licensing is required, they’re now included in the standard product.
Dynamically grant user permissions
Following the ability to use your own end user management system and the SET USER ALIAS command, you might be wondering how you can manage end user permissions without creating multiple 4D user accounts. Keep reading because this feature release has the answer!
Server code development in project applications
Developing and debugging server code in project applications has become easier than ever in 4D v18 R4. Without further ado, let’s take a look at how to do it.
Multiple web servers in a single 4D instance
Have you ever needed to use multiple web servers in order to, for example, split your web application code into several business units, or separate the administrator’s web server from the user’s or run an old part, not preemptive-ready yet, in a separate instance, allowing the main part to run preemptive?
If you’re nodding your head yes, then keep reading because 4D v18 R3 allows you to do so … with ease.
Who did what: Store user aliases in the journal
By now, you’ve surely discovered the new ability to identify your users thanks to the SET USER ALIAS command. In 4D v18 R2, the command’s behavior has been extended. How? Keep reading!
Take control of your work area
Want to adapt your application’s interface to your end user’s system preferences? Want to make sure your application’s interface isn’t obscured by the macOS dock or menu, or by the Windows taskbar? In this blog post, we’ll show you how!
Enable Debugger for PROCESS 4D TAGS in compiled mode
PROCESS 4D TAGS has been enhanced with each 4D version and the latest additions as 4DCODE have drastically increased the use cases. What was previously a single line of code, is now often many lines, even pages, of 4D code.
Coexistence of thread-safe and non-thread-safe commands
Have you ever needed to use methods with both thread-safe and not thread-safe calls, with conditions that skip over commands that are not thread-safe? Currently the compiler prevents doing this and an error is thrown, however there’s a flag that lets you disable this check and this blog post shows you how.
