Webinar: Delphi Legacy Applications to Unicode-Enabled Delphi 2010

Embarcadero Webinar : Join Delphi Expert Cary Jensen...
Visit the Embarcadero site to watch this Webinar

Delphi 2009 and 2010 introduced significant changes to the basic string classes in order to support Unicode. Even if you never plan on supporting multiple languages in your applications, these changes have important implications for how you work with strings, especially in those applications originally created using an older version of Delphi.

Now, Cary Jensen has worked with more than 20 Delphi developers around the world – including noted authors, leading third-party vendors, and front line developers – to learn how they approached their Unicode conversions, what challenges they faced, and what solutions they employed.

Delphi White Paper: Delphi Unicode Migration for Mere Mortals

Delphi Unicode Migration for Mere Mortals: Stories and Advice from the Front Lines, Cary Jensen

Abstract: There are a lot of different ways that RAD Studio's Unicode support can affect your existing applications. And in order to help RAD Studio developers migrate their existing applications, we reached out to those in the greater developer community who have made the switch, asking for their advice, techniques, and tools that helped them with their Unicode migrations. This white paper is the result.

This white paper includes both a technical overview of how RAD Studio implements Unicode support, as well an exploration of various parts of your applications that may be affected by these changes. Advice, code samples, and general observations regarding Unicode migration from some of the top names in the RAD Studio community are included.
