Embarcadero today introduces a brand new first-class AWS client library for Delphi, soon to be included in the Enterprise and Architect editions of Delphi and RAD Studio. Given the relevance of Amazon Web Service cloud infrastructure in today’s IT landscape, including an AWS library in our product offerings delivers substantial added value to our customers. The Agreement With Appercept Embarcadero has reached a two-year exclusive distribution agreement with Richard Hatherall, the UK-based owner of Appercept, on the company’s “AWS SDK for Delphi”. The deal includes an initial preview, with additional features to be released over time. The AWS library and updates will be available via GetIt, and limited to customers on Enterprise and Architect with active update subscription. Customers using the AWS library also get support by Appercept through Embarcadero’s own support team. The library does not currently support C++Builder, but there are plans to provide C++ support for the AWS SDK in the future. Why An AWS SDK For Delphi Amazon Web Services (AWS) is the world’s leading cloud service today, with well over 50% market share. AWS offers many services, from storage and orchestration to AI services and insights, and it’s leading a transformation in the industry. The availability of an easy-to-use, high-profile AWS SDK for Delphi from Appercept will make it much easier to use AWS cloud services in Delphi client applications, both for desktop and mobile, and will be particularly useful when building server applications, especially if they are deployed in the AWS infrastructure. Closer Look: What to Expect From the Appercept AWS SDK for Delphi The Appercept AWS SDK for Delphi makes heavy use of modern language and framework features, from PPL (Parallel Programming Library) to anonymous methods for async operations, as required by a good REST client framework. This library offers direct mapping to the AWS APIs, starting with a few services like storage (S3) and notifications (SNS) plus a solid support of user accounts and access permissions. Not only does this SDK make the APIs available as direct calls (mapped internally to Delphi’s HTTP client library as needed), it also offers many easy-to-use constructs and data structures, so that the most common AWS operations will require a very limited amount of code while allowing developers to focus on their business logic. The library comes with extensive documentation and demos, making it easy to embrace. It also ships with full source code, enabling users to learn how the solution works and debug it directly within their applications. Want a quick demo? This is all you need to write to have a list of S3 buckets (or folders): uses AWS.S3; var  S3Client: IS3Client; begin  S3Client := TS3Client.Create;  var Response := S3Client.ListBuckets;  for var BucketName in Response.Buckets do    ListBox1.Items.Add(BucketName); uses AWS.S3; var  S3Client: IS3Client; begin  S3Client := TS3Client.Create;  var Response := S3Client.ListBuckets;  for var BucketName in Response.Buckets do    ListBox1.Items.Add(BucketName); What To Do Next If you missed the “Introducing Appercept’s AWS SDK for Delphi” webinar on the 15th of December, you can catch the webinar replay soon after. We’ll post the link here as soon as it’s available. We will also be posting additional information as new features are added and coverage of AWS services grows.

Building database applications with RAD Studio (Delphi & C++ Builder) gives the best experience for developers. For instance, if you want to connect to a database, just drop a database connection component into the project and select the source of the data. Then open the LiveBindings designer and link the database fields to the UI controls and that is it! If you want to connect to a remote database you can make use of the REST Client Library and Rad Studio’s incredibly powerful REST Debugger. Perhaps you need to connect Azure or AWS? That is covered too – just drop the Cloud Connection Provider component. configure it securely, and everything works right away. What sort of topics are covered in this article? We’re going to take a whistle-stop tour through some of the ways using Rad Studio Delphi and C++ builder can make life much easier for developers looking to work with database servers and data. What is FireDAC? How can I convert my programs from the Borland Database Engine BDE to FireDAC? How can I connect to Amazon Web Services and Microsoft Azure with Delphi or C++ Builder? What is the Embarcadero REST Client Library? How do I bind a data source to UI controls in seconds? What is FireDAC? FireDAC is a multi-device data-access library that comes with RAD Studio Delphi and C++ Builder. One thing you can do with FireDAC is talk to SQL databases. You can also make use of an ODBC connection to talk to ODBC data sources.  With its powerful universal architecture, FireDAC enables native high-speed direct access from Delphi and C++Builder to InterBase, SQLite, MySQL, SQL Server, Oracle, PostgreSQL, DB2, SQL Anywhere, Advantage DB, Firebird, Access, Informix, DataSnap, and more, including the NoSQL Database MongoDB. FireDAC features: An enterprise-grade data access engine A unified API Has high-performance Data Access Where can I learn more about using FireDAC? How can I convert my programs from the Borland Database Engine BDE to FireDAC? On the FireDAC page, there is the BDE to FireDAC set of steps that will take you through taking the existing source code, your existing forms in Delphi, and running refined utility which is per-regular expression search and replaces utility. Also, there is a script for migrating BDE that will convert the forms and source code for Delphi into use FireDAC whether it is in data modules on your forms or in your source code for database connectivity.  In general, the FireDAC components have a high compatibility level with the BDE data access components. This includes the syntax and semantics of the properties and methods in the FireDAC and BDE. You can learn some other parts which are different in Migrating BDE Applications to FireDAC.

Delphi & C++ Builder come with Cloud components that allow you to easily utilize cloud services from Amazon Web Services and Microsoft Azure. As you can see, these two core components can be used to connect to AWS or Azure. There is a really helpful sample project called CloudExplorer, that familiarizes you with how to: Initialize Connection Get Selected Account Update Cloud File List Get Selected Cloud File Upload Selected Local File Download Selected Cloud […]

I keep telling anyone I can, Delphi is superb language for developing applications for all platforms, desktop, mobile or the web. Delphi can make gorgeous apps for the desktop such as Windows, Linux or macOS and yet is just as capable for mobile devices such as iOS and Android. You can create web apps with Delphi – not just simple pages but fully capable involved creations which contain all the power and functionality that is possible on the modern web. But don’t just take my word for it – take a whizz through any of the articles on this blog, watch sessions from DelphiCon 2021 and the Desktop First Summit or visit the wonderful DelphiBooks website and take your pick from the many authors on there. In fact, this year has proven to be a bit of frenzy when it comes to new Delphi books, driven in part by Packt who are fast proving to be major champions of books relating to Delphi. There’s even an updated Delphi Alexandria 11 version of the Delphi must-have Object Pascal Handbook by Marco Cantú which you can download for free. It’s Packt who once again are the publishers behind the most recent addition to the Delphi literary library: Fearless Cross-Platform Development with Delphi by Delphi MVP David Cornelius. As soon as I read chapter rundowns during the run up to the release period, I pre-ordered this book. It was worth every cent. Here’s my review. Why Fearless Cross-Platform Development with Delphi? I only have one issue with David Cornelius’ book “Fearless Cross-Platform Development with Delphi” and it’s the title. This book should have been called something like “how to do almost anything you could ever want with Delphi” because that’s exactly what this book is. A handbook on how to write modern applications using the Delphi language so that they look, work, and behave nicely on almost any computer or device you can think of. It’s an opening opus of quite spectacular proportions. It’s a love story of the power and flexibility of the Delphi language. It’s a gripping tale of diving into a sea of development tasks and possibilities and emerging with the pages dripping with tips, tricks and techniques which cover almost absolutely anything you could want to do as an application developer writing apps that can work on desktops, mobile and even the web. I struggle to believe this is David’s first book. If it is then he must be encouraged by us all, and Packt his publishers, to draw on his skills to write some more. “Fearless Cross-Platform Development With Delphi” takes us on a journey from the basics of using the IDE, Delphi’s integrated development environment, project management tips, through more esoteric topics like the command line compiler. After that whirlwind “this is how to do it” introduction, suitable for newcomers to RAD Studio’s development ecosystem, David goes on to give a brief overview of how Delphi’s Object Pascal language came about, emerging as it did from the likes of Apple Pascal and the greatly-loved Borland Turbo Pascal. He takes care to point out how Delphi has continued to evolve from those early beginnings so that it incorporates a whole range of modern programming language features embracing constructs and capabilities to ensure it not only remains technically competitive […]
