You asked for a way to import and export different document formats via the 4D Write Pro widget and once again, 4D listened!
In addition to the 4D commands that already allow you to import and export documents in different formats, such as export .docx format with 4D v17 R4 and PDF format with 4D v18 R4. Now, 4D Write Pro can import and export different document formats via the widget from the toolbar and sidebar.
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.
List boxes are powerful form objects. They’re easily created and manipulated, and most importantly, they can handle any kind of data. Additionally, they can be fully set up by programming … everything from inserting or deleting rows and columns, to defining or modifying tons of properties using the 4D language. With 4D v18 R4, another important property has been added to the list. Can you guess which one? Hint: read the title again.
4D View Pro automatically recalculates the formulas in your worksheet when you change data they depend on (e.g., entries, formulas, names, etc.).
But what if you want to make your UI more interactive and trigger the calculation of formulas whenever you want? 4D v18 R4 makes it possible thanks to three new commands: VP SUSPEND COMPUTING, VP RESUME COMPUTING, and VP RECOMPUTE FORMULAS. These commands let you suspend and resume the calculation of all formulas in your document, or force their recalculation.
4D for iOS already provides the ability to build detail forms from the Forms section. Starting with 4Dv18R4, we’ve added even more flexibility for building detail form templates. Here’s how.
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!
Have you ever created an HTTP data request only to get hit by a red “access to HTML request has been blocked by cors policy” error?
When your site is on the same domain as the web service server, there’s no problem. However, this isn’t the case when performing a cross-origin request. Access is denied due to browser security preventing HTTP requests to another domain. The result? A CORS policy error.
To help you explicitly allow certain cross-origin requests on your server, 4D now supports the CORS protocol. Accessing data with cross-origin requests just became easier!
Have you ever wondered about 4D’s autocompletion feature or asked yourself why 4D suggests all functions used in the code? Since an object is a very generic type, 4D only knows what it’s really storing at runtime. However, that doesn’t help much when you’re writing your code.
4D now offers a new, alternative syntax which will greatly enhance autocompletion when declaring your variables.
As a 4D Write Pro user, you’ve most likely used expressions (or more recently, formulas) to automatically fill in certain parts of your documents. These formulas can return “raw” text or images. In the case of text, they may contain line breaks. The question is how should these line breaks be handled when they are processed inside 4D Write Pro documents? This blog post provides the answers … keep reading!
4D solutions have always been safe and stable. This is because 4D invests heavily in developing and updating security features. 4D continues this focus in 4D v18 R4 with a new feature to further enhance its security toolkit. A new class providing a set of methods to perform common cryptographic operations is now available: CryptoKey class.
