How to easily handle text insertion in 4D Write Pro

4D Write Pro packs in a lot of commands and functions allowing you to create and handle complex documents by programming, documents which include pictures and text! Today, 4D Write Pro gets its own commands to insert and read text without needing to use commands originally designed for Styled Text! Thanks to these new commands, your code takes full advantage of the 4D Write Pro programming concepts, i.e. objects and ranges. Thus, your code is more elegant and easier to read!

Get machine hardware information

4D v17 goes a step further to let you create a customized server administration dialog. Following the ability to retrieve information about users & processes, getting all runtime information about 4D Web server, as well as details about the active license, you now have the ability to also retrieve all of the hardware and system details for the machine running your 4D server.

Do you need to know what OS is being used, what processor(s), how much RAM is available, etc.? Just call the new Get system info command, locally or remotely! And that’s not all, this command can be extremely useful for quickly diagnosing and solving any problems that may arise.

Handle entities in an entity selection

FIRST RECORD, LAST RECORD, NEXT RECORD, PREVIOUS RECORD; does that ring any bells? I bet it does. You’ve already been using them to handle selections! ORDA provides useful and familiar methods to navigate through entities in an entity selection – and obviously, some perks!

For starters, you can handle several entity selections at the same time and navigate through them independently, whereas normally you can only manage a single ‘current selection’ per table. That’s precisely what we’re going to see in this blog post.

Working with ORDA optimistic locking

4D v17 introduces ORDA, a major evolution in 4D which is opening a world of new possibilities for 4D developers. One of the benefits of using ORDA is related to record locking, because ORDA offers a choice between optimistic and pessimistic locking. After having introduced the ORDA locking mechanisms, we continue the ORDA series so you can discover how to work efficiently with optimistic locking with ORDA.

Use table ranges in 4D Write Pro

Since 4D v16 R4, it’s been possible to create tables by programming in your 4D Write Pro documents. Styling the whole table or just certain cells could be done during the creation of the document, but maybe you also want to manage your tables afterwards. Now, it’s easy to manipulate tables in an existing document, to change the border style or color, to change the font size or make it bold, etc.

4D Write Pro programming is highly based on “ranges“. After paragraph ranges and picture ranges, 4D v17 introduces a new type of range: table ranges, returned by a new command: WP Create table range. Styling tables is now simple with this new command and new type of range!
