It was so much fun to create one of the "Developer Skills Sprint" sessions last week. During the live Q'n'A session I have promised to make the source code of my DataSnap "Simple Calculator" REST server and client projects available. Here it is! It is now available from the Code Central at http://cc.embarcadero.com/item/29915 A few years ago, back in the Delphi XE time frame, I have created a series of DataSnap "Delphi Labs". The source code of these Delphi Labs has been updated to Delphi...

Welcome to "Delphi Tuts"! Your Delphi step-by-step tutorials! In this tutorial we are going to use Delphi XE5 to build the simplest possible DataSnap client/server system. The difficulty level of this lab is “Hello World”. This step-by-step tutorial is intentionally very simple, so even not experienced Delphi programmers should be able to build projects described here. The objective of this lab exercise is to get familiar with basic steps needed for building DataSnap servers and clients. ...

I'm happy to announce that I'm starting a new series of step-by-step tutorials about Delphi programming: DELPHI TUTS! Programming in Delphi is fun and I really love writing Delphi code. I think I'm addicted to Delphi. I have been passionate Delphi programmer since Delphi 1 and I'm only more and more enthusiastic about Delphi with every new release. There is no other tool on the market today like Delphi. With the latest release - Delphi XE5 - using one programming language, one framework, you ...

During my CodeRage 8 "Secure DataSnap Development" session I'm demonstrating different levels of security in DataSnap architecture. Communication Protocol: DataSnap supports three different communication protocols: TCP/IP, HTTP, HTTPS. Choosing the HTTPS protocol that is implemented using SSL (“Secure Sockets Layer”) adds encryption to the communication between client and server, making it a secure solution. Two other protocols – TCP/IP and HTTP – are inherently not safe and such a commun...

It seems that it is my very first post in the New Year 2013, so I wish You all the best and great time writing all kinds of programs. I'm sure it is going to be a great year for Delphi and Marco is predicting it as well, especially that next month Delphi is going to become adult! Two years ago I have put together a serie of Delphi DataSnap tutorials called "Delphi Labs" and many people found it useful, so I thought that it is a high time to at least update code samples for every tutorial so t...

The CodeRage7 online Delphi developer conference is in full swing! There is plenty of great content and I'm looking forward to replies of some sessions as it is impossible to follow all of them! To me the biggest news is to have Marco Cantù appointed as the new Delphi Product Manager! Welcome to The Team! In a moment my "Building Scalable Multitier Systems with DataSnap XE3" starts. It is prerecorded and I have promised to put the link to source code of all demos presented on my blog, whic...

FireMonkey is busy;-) I'm just back from Belgium where I was presenting FireMonkey, Delphi and RAD Studio XE2 in Lier at the event organized by Embarcadero-Benelux and PeopleWare. PeopleWare work closely with Embarcadero providing Delphi expertise to customers in Belgium. There are a lot discussions among developers which technologies to choose and to me it is becoming clear that there is nothing like native C++ and Delphi development for mobile and desktop. For simple applications ...

Yesterday I was playing with implementing "parallax" starfield simulation in a Delphi XE2 iOS HD project as documented here. To be honest at the beginning my plan was to implement a classic "deep space" starfield simulation, but could not find any code samples, so decided to go for a simpler "parallax" approach. I have posted my demo internally for other Embarcadero technical evangelists to enjoy and got back almost instantaneous feedback from David I: "Looks like falling rain. Was hoping for...
