With 4D v16 R2 you can display a graphical horizontal ruler at the top of the 4D Write Pro area ! Thanks to this horizontal ruler, the text can be easily formatted.
Prior to the existence of this graphic ruler, tabulations could only be managed by programming or using the 4D Write Pro interface widget. From now (4D v16 R2 and above), when the ruler is displayed (this is optional) the final user will have the opportunity to manage margins and tabulations easily and graphically.
4D v16 introduced a new fully optimized cache manager for the 64-bit product line. 4D v16 R2 is giving power to our advanced 4D developers to take control by themselves!
The cache manager internal algorithm is based on a priority concept associated to each object type to store in the cache memory. By default, the cache manager algorithm assigns a higher priority value for an index than for records. And recently used objects (records or indexes) have a higher priority to remain in the cache than objects that have not been used in the last two days, etc…
I am pleased to announce that the beta testing of 4D v16 R2 starts today!
4D v16 R2 delivers the final version of Altura-free 4D Developer Edition Windows 64-bit as well as great improvements, among other things, as listed below:
- Better integration into the enterprise with Virtual Machine Snapshots Support
- More control and higher flexibility for the developer: Cache Manager priority control, new programmatic possibilities for list boxes, search in array in objects using linked arguments,…
- Improved user experience: horizontal ruler in 4D Write Pro, cross table in Quick Report 64-bit editor as well as a revisited Find in Design dialog.
Thanks to its new features and advanced core technologies, 4D v16 enables you to create and run scalable, rapid, flexible and engaging applications, easily adaptable to changes in business needs. It helps you speed up development and cut complexity, so you can focus on your priorities and seize new opportunities. You can check the complete list of 4D new features. Some of the 4D v16 key advantages are summarized here after.
We are moving forward with 4D v16 on preemptive multi-threading as the 4D Web Server is also becoming preemptive. Just click one checkbox and your application will support more simultaneously connected users, and process more requests in parallel. For requests using a lot of CPU time, execution can be up to 2 times faster!
The 4D v16 version has definitely been designed for better performance and scalability. In addition to major features like preemptive multi-threading, 4D v16 64-bit is embedding a brand new cache manager for a optimized handling of objects in cache memory avoiding any fragmentation issues.
The new cache manager improves the usage of very large cache for modern computers (with 64 or even 128 GB of Cache) allowing to take advantage of low RAM prices to have even large databases fully in memory. It also improves the situation of small cache size with very large data files, by decreasing the amount of unloading memory with increased support of priorities for data objects to be hold or released from cache.
QuickDraw/QuickTime pictures (PICT format) are deprecated since 4D v11 and must be replaced by modern picture formats (such as PNG or JPEG). New 64-bit versions of 4D no longer support PICT images. So the challenge is to find them in your old applications.
You want to visualize occurrences of a given variable in the 4D method editor? Or you find your method code too heavy with all those block icon and lines everywhere that it’s becoming hard to read?
With 4D v16 new preference options are available in the code editor to make the 4D developers’ life easier!!
If you’re used to run multiple 4D instances of an application on the same system, we are introducing with 4D v16 a feature that will simplify your life.
You now have the possibility to associate a set of different user settings with each data file.
Since 4D v11, the database server and SQL server both use preemptive multi-threading. Starting with 4D v13, the Web Server in Static mode also uses preemptive. Now with v15 R5, the 4D language can also be run in preemptive processes.
