Want to enhance your database scalability and use all the performance available with your multi-core machines?
With 4D v16, we have extended the list of thread-safe commands in order to use preemptive processes with your code handling XML.
With the new network layer, we can implement new functions that were impossible with the legacy network layer. The first is the application sleep notification.
4D v16 is now providing an easy and smooth product activation. Either for development or for deployment, benefit from an improved user experience when activating your 4D products!
The DELETE FOLDER command has been enhanced with an optional parameter that permits you to delete the selected folder and its contents at once.
From 4D v15 R5, you can add an icon in the listbox header by programming. The image can come from a file, a picture variable or the picture library. This icon can be placed on the left or on the right side of the column.
With 4D v15 R5, 4D Write Pro is moving forward!
A new page view mode is available and two new commands are available in order to print a document.
For our customers running client-server applications on Windows, it is possible with 4D v15 R5 to enhance the end-user experience by using the Single Sign On feature, which basically allows your end-user logged into the system to also use their 4D application without being asked to re-enter any login/password.
A powerful new syntax is available for 4D tags inside texts and Blobs to be processed.
This new syntax is supported in two cases:
- files with “.shtml” extensions served by 4D Web Server
- Text and Blobs sent as parameters to the PROCESS 4D TAGS command
The new syntax is available for three tags, 4DEVAL, 4DTEXT and 4DHTML, which can now be written prefixed with a $ (dollar sign) rather than as HTML comments.
With 4D v15 R4, a new parameter is introduced for the DISTINCT VALUE command. This parameter must be an array, and it receives the count of each distinct value in a selection of records.
This feature is particularly useful for obtaining statistics on records, or to order records by their most common type.
A new system variable is available to get the offending 4D code that generates an error. With 4D v15 R4 whenever an error is raised you have a means to get the offending code in addition to getting the error code, as well as the method and line where the error occurred.
