Ray Konopka – Raize Software
Relevant to: All-Access, JBuilder
One of the benefits of WPF is that it is flexible enough to handle many situations that would typically require creating a custom control in another user interface framework. However, there are still times when creating a custom control is appropriate and this session covers what you need to know to get started. Topics include user controls vs. custom controls, base class selection, dependency properties, routed events, templates, and much more.
In order to use the ADO.NET Entity Framework effectively, you must understand its value-based data model, which is distinctly different from the SQL and ORM approaches to representing and querying data. Programmers who approach the Entity Framework as "just another ORM" often find themselves frustrated or disappointed, a common reaction to trying to force a square peg into a round hole. This presentation examines the Entity Data Model in-depth, explaining where it fits into the context of a larger application, and demonstrates different techniques for retrieving and altering data. Also covered are performance considerations and future directions.

This session shows how to create and use a DataSnap REST Client Module to access a Delphi DataSnap server and call the functions exposed by the Delphi DataSnap server. DataSnap is a technology that enables RAD creation of multi-tier web applications. We will use HTML5 Builder to create a client-side web applications that interacts with DataSnap. A DataSnap REST client module is a data module that lets you access a DataSnap server. You can then include that data module in another data module or a web page to be able to call the functions exposed by the DataSnap server.
