Often when you create a table, you might need to combine two or more cells to create a centered title on a particular section of your table. As of 4D v18 R4, a new set of commands is at your disposal to help you merge and unmerge a group of cells by programming. Let’s take a look at some examples.
In 4D v18, we introduced a new way to send emails. Then in 4D v18 R2, we added a new way to retrieve emails using POP3. Now in 4D v18 R4, we’re taking the first steps for a new way to handle the IMAP protocol. As we did for SMTP and POP3, there’s a new IMAP New transporter command to handle the IMAP protocol.
The Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server. This protocol makes it possible to manage multiple mailboxes, download emails, perform searches on the server, manage message state, and a lot more!
And with this first IMAP feature, you can add methods to the transporter to: have the list of the available mailboxes, select a mailbox, and receive email from the selected mailbox. Let’s see how.
What if I told you that with 4D v18 R4 you can export 4D Write Pro documents directly to PDF format (on both macOS and Windows), without needing to install any printer drivers or additional software? Now you can … and that’s not all! You’re also able to set several options for both the form and the content. Keep reading to learn more!
4D v18 R4 delivers a very exciting feature … Push notifications. These are messages sent directly to the user’s mobile device from your app. Push notifications provide users with relevant information to encourage them to engage with an app. As of this feature release, 4D for iOS not only allows doing so but also allows you to do it with ease!
For email authentication, 4D for iOS also makes your life easier.
Let’s see it in action!
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.
An increasing number of developers are using the Form command to link their form objects and many of you require easy programming access to the values of those objects. So, to help you access the value of a form object, regardless of its variable or expression, we’ve added two new commands: OBJECT Get value and OBJECT SET VALUE.
Let’s see how to use them!
Monitoring access to your mobile app is a very important capability that deserves further consideration. Email validation is one of the simplest and most secure ways to determine the authenticity and legitimacy of the person trying to log into your app. 4D for iOS enables you to easily handle this validation process by verifying that an email comes from whom it claims to be sent from, and by allowing you to block harmful uses of the email.
Want to dynamically generate 4D View Pro documents on a server and, for example, send them by email or calculate values? 4D v18 R4 introduces a new command to manipulate 4D View Pro commands in an offscreen area: VP Run offscreen area.
In a previous blog post, we introduced you to the world of ORDA data model classes. Now it’s time to get our hands dirty and learn more!
You already know that ORDA’s structure (datastore, dataclass, entity, entity selection) is made up of objects. But they’re not just objects, they’re strongly-typed objects linked to specific ORDA classes. This means that you can write functions to hide the complexity of your data’s physical implementation.
