Olaf’s Thoughts About Development

There is now a Twitter feed for all news, live tweets and possibly even Delphi product announcements as they happen in San Jose.

Follow feed : www.twitter.com/delphilive2009

It took a bit longer than expected, but the detailed schedule of DelphiLive! is now online:

The registration form also has a package offer, which includes 4 days conference and accommodation at the conference hotel (San Jose Mariott)

DelphiLive! May 13 – 16, 2009, San Jose, California
The Delphi Developer Conference

Embarcadero is apparently in the process of blowing out an e-mail blast, which “silently” announces Instant-On(TM), a mechanism which basically eliminates the installation process. You get one executable per product, run it and it will, well, “run”.  No more tedious installation procedure.

As far as I understand this technology, you would even be able to keep your Delphi (or any other Embarcadero product) on a USB-stick, and run it on any computer you like.  Just plug in the stick and run the exe. Very cool!

I’m excited to get a first demo of this in my hands!

Here is the online-version of the (German) newsletter announcing this technology.

Update: The AllAccess information page also contains the note about “InstantOn. In fact it was already mentioned in the earlier press release of AllAccess – but apprently it didn’t get much attention.

Quote: “On-Demand Power with Embarcadero InstantOn™

A unique, innovative capability in All-Access is Embarcadero InstantOn. With InstantOn, you can simply click-and-run the selected tool on-demand, either locally or over your network, without full installation on your local machine. InstantOn saves valuable time by allowing quick access to tools, even in locked-down desktop environments where installing software is problematic.”

The just announced DelphiLive! conference in San Jose will have two tutorial/workshop days.  I will offer a full day workshop on IntraWeb/VCL for the Web.

To register, you need to sign up for one of the “tutorial days” at DelphiLive! Registration The exact date (Wed or Sat) will be announced soon. (You may leave a note with your preference below)

VCL for the Web / IntraWeb Workshop

This Power Workshop starts with providing an overview of the available Web development tools for Delphi/C++ Builder. During the introduction the different approaches of WebSnap / WebBroker (Win32), ASP.NET (.NET) and IntraWeb will be explained. The differences between page- and application-oriented Web development will be discussed to finally introduce the Application Mode of IntraWeb.

The goal of this session is to learn the base skills to develop a complex Web application. Both strategies, starting from scratch or porting an existing Windows desktop application, will be taught.

Agenda

Part I

• The first Application
• Available components
• Deployment / Server Installation

Part II

• Session Handling
• Multi-Threading
• Multiple Form Applications

Part III

• RIA – Rich Internet Applications
• Ajax – Asynchrones Web
• JavaScript
• Dojo

Part IV

• Data Access
• Templates and Visual Form Inheritance
• (Reporting, Scaleability, Security)

Requirements

Basic skills in Delphi or C++ Builder are required. Examples are shown in primarily in Delphi, but depending on the attendee structure C++ samples can also be shown. Please bring your laptop. Delphi 5 or better should be pre-installed. IntraWeb can be installed with the help of the trainer.

The just announced DelphiLive! conference in San Jose will have two tutorial/workshop days.  In cooperation with Holger Flick I will offer a full day workshop on Delphi Prism – the new Delphi for .NET development environment.

To register, you need to sign up for one of the “tutorial days” at DelphiLive! Registration The exact date (Wed or Sat) will be announced soon. (You may leave a note with your preference below)

This workshop introduces Delphi Prism and will provide an overview of the most important .NET technologies such as Windows.Forms, WPF, ASP.NET, ADO.NET and LINQ.

Prism’s syntax differences to Delphi native and its language enhancements/advantages over C# will be discussed with many samples.

Database access, Web development and desktop application development will be covered as well as topics like how to migrate from Delphi native to Delphi Prism.

Im Rahmen des kommenden Delphi CodeCamps werde ich in Zusammenarbeit mit Holger Flick einen Workshop zu Delphi Prism anbieten.

Sie können einen einzelnen Tag buchen oder aber natürlich auch das ganze CodeCamp.

Einführung in die professionelle Softwareentwicklung unter .NET mit Delphi Prism

Dieser Intensiv-Workshop vermittelt den Teilnehmern zunächst einen Überblick über die Handhabung von Delphi Prism und Visual Studio.

Im weiteren Verlauf werden die verschiedenen allgemeinen Aspekte der Softwareentwicklung unter .NET vorgestellt und analysiert.

Für den Umstieg von der klassischen Delphi-Entwicklung auf die .NET Entwicklung unter Prism werden zahlreiche Tipps und Tricks gezeigt. Der gemischte Betrieb von Delphi für Windows 32 und .NET wird ebenso thematisiert.

Abgerundet wird der Workshop durch Themen wie Web- und Datenbankentwicklung.

Im Rahmen des kommenden Delphi CodeCamps werde ich einen Workshop zur Webentwicklung mit Delphi und  IntraWeb (VCL for the Web) anbieten.

Sie können einen einzelnen Tag buchen oder aber natürlich auch das ganze CodeCamp.

Entwicklung von Webanwendungen mit der VCL für das Web / IntraWeb

Dieser Intensiv-Workshop vermittelt den Teilnehmern zunächst einen Überblick über die verfügbaren Webanwendungs- Technologien in Delphi / C++ Builder. Dabei werden insbesondere WebSnap / WebBroker (Win32) und ASP.NET (.NET) gegenüber der VCL für das Web (IntraWeb) abgegrenzt. Es werden die Unterschiede zwischen Seiten- und Anwendungsorientierter Entwicklung dargestellt, um dann auf die Anwendungsorientierte Entwicklung mit der VCL für das Web zu fokussieren.

Im Vordergrund dieser Veranstaltung steht das Erlernen der notwendigen Kenntnisse, um eine komplexe Anwendung mit einem Web-Interface auszustatten. Dies kann entweder eine Neuentwicklung sein oder aber auch das Umstellen bzw. Erweitern einer bereits existierenden traditionellen Anwendung.

  After quite a while there will be a face-to-face Delphi Developer conference in the US again.

The conference is organized by S&S Media and supported by Embarcadero/CodeGear.

We have got all the top speakers, including Cary Jensson, Marco Cantu and Ray Konopka.

Many (most?) members of Delphi R&D team (including Barry Kelly – “The Delphi Compiler”) will be at the conference and there will be of course "Meet the Team" sessions.

All Sessions are online and registration is now open. The speakers list includes all those who already submitted their bio and photo. For a complete list of speakers please refer to the list of sessions for now.

If you register before April 10th, 2009, then you can take advantage of the Early Bird rebates.

When : May 13 – 16, 2009
Where: San Jose, CA, USA

Recently I came across the question how to build a special kind of polymorphic query, that returns only one specific member type out of many different types in a given source.

Lets assume these example class definitions (all examples given in Delphi Prism syntax – the idea applies to other .NET languages as well of course)

type
Car = abstract class (Object)
public
HorsePowers: Integer;
Model: String;
Owner: String;
end;

Volkswagen = class(Car)
public
end;

Porsche = class(Car)
public
SpeedLimiterActive:Boolean;
end;
