General Questions

What is Delphi?

Delphi 2010 - Used by millions of developers and supported by thousands of 3rd party components and add-ons, Delphi 2010 is the premier rapid application development environment for building high-performing end-user focused applications. Delphi combines a leading-edge object-oriented language, ultra-fast native compilation, heterogeneous database connectivity, and a rich visual component framework to enable you to deliver powerful applications up to 5x faster and with fewer developers across multiple Windows and database platforms. Delphi's fully visual two-way RAD IDE powers hundreds of time-saving features designed to simplify and speed visual and data-intensive applications - from native Windows GUI desktop applications to interactive touch-screen, kiosk, and database-driven multi-tier Web applications and services.

Which editions are available and what are the differences between the editions?

Delphi Professional
Delphi 2010 Professional is designed for developers building high-performance desktop GUI and touch-screen applications with (or without) embedded and local database persistence. Delphi 2010 Professional's ability to generate fast single exe Windows applications with rich user experiences makes it especially well suited for ISVs building highly-graphical "packaged" Windows applications that seamlessly support an array of Windows versions without modification. Features include:

  • Local database connectivity to InterBase®, Blackfish™ SQL and MySQL
  • Blackfish SQL deployment on systems with 1 user, 512MB database size
  • VCL for the Web with limit of 5 connections
  • UML code visualization, providing a visual representation of source code for easier understanding

Delphi Enterprise
Delphi 2010 Enterprise is designed for developers building rich, data-oriented client/server and multi-tier GUI and Web applications that work seamlessly with a wide variety of database servers and data sources. Delphi Enterprise's high-performance heterogeneous database server support is ideal for multi-vendor database server scenarios, or building turnkey applications that can work with a wide array of database servers. Delphi Enterprise includes everything in the Professional edition, plus the following for building client/server and multi-tier database and Web applications:

  • Database server connectivity to InterBase, Blackfish SQL, Firebird, MySQL, Microsoft SQL Server, Oracle, DB2, Informix and Sybase
  • DataSnap multi-tier application development
  • Blackfish SQL deployment on systems with 5 users, 2GB database size
  • VCL for the Web with no connection limit
  • Full two-way UML modeling capabilities with multiple diagram types, synchronization between code and models, documentation generation, and design patterns

Delphi Architect
Delphi 2010 Architect is designed for developers and teams building data-intensive client/server GUI and Web applications with large or complex enterprise database systems. Delphi Architect combines data-driven rapid application development and heterogeneous high-speed data access with rich visual data modeling to help developers understand, design, and get the most value out of existing enterprise databases and data structures. Delphi Architect includes everything in the Enterprise edition plus powerful database modeling and design capabilities:

  • Reverse-engineer, analyze, and optimize databases
  • Automatically generate database code from models for forward engineering
  • Create logical and physical models based on information extracted from databases and script files

Technical Questions

Can I develop applications on one version of Windows and deploy to others?

Yes. You develop applications on the Windows OS that is most productive for you, so you can develop applications on your choice of operating systems (Windows 7, Windows Vista, XP, Server 2008 or Server 2003). Applications built with Delphi will run on all of those Windows versions plus Windows 2000.

Will applications built with Delphi 2010 run on older versions of Windows including Windows 2000, 95, 98 and Me?

Because of the use of Unicode as the default string type, Windows 98, 95, and ME will not run applications produced with Delphi 2010. These operating systems do not support Unicode strings, and Microsoft has dropped support for them. Applications built with Delphi 2010 will run on Windows 2000.

What are the pre-requisites for installing Delphi?

To install, you will need to have installed on your system:

  • The Microsoft .NET Framework 2.0 or higher
  • The Microsoft Visual J# 2.0 Redistributable Package
  • Windows Internet Explorer® 6.0 or higher
  • MSXML 6

The installer will install the prerequisite software if you don't already have it installed.

I'm wondering about moving my existing code to Unicode. What do I need to do?

Most existing code will work fine using the new default UnicodeString. Code that does byte level manipulation of string data, or that carries data in string variables probably needs to be examined and perhaps updated to account for the new character sizes inherent in Unicode string data. For more information, see the documentation and Embarcadero Developer Network for information about moving existing code to Unicode.

Do I have to register my copy of Delphi?

Yes. When you first run the product, a small application will open and ask you to register the product. Once that is done, and your product key is validated, then your product will be registered and installed.

Can I open my projects created with earlier versions of Delphi?

Yes, you should be able to do so, depending on the installed components required by your projects. Delphi 2010 uses the MSBuild system for the build engine, and thus requires a new project file if you are upgrading from version 2007 or earlier. However, the IDE will seamlessly update your projects to the new format.

What if I need to deploy Blackfish SQL in situations beyond those allowed with the license included Blackfish SQL RAD Studio Edition license?

Additional Blackfish SQL deployment licenses are available separately for purchase. See the Embarcadero online shop site for your country or your favorite Embarcadero reseller partner for pricing.

Can I develop .NET applications with Delphi 2010?

No. Delphi 2010 produces only native Win32 binaries. You can import .NET assemblies as COM objects, but the code produced by Delphi 2010 is strictly native Win32 code. Embarcadero offers Delphi Prism for .NET development with a Delphi-based language. Delphi Prism is available standalone or combined with Delphi 2010 in Embarcadero RAD Studio 2010.

Why do I need to install the Microsoft .NET runtimes and SDK with Delphi?

Some of the functionality of the IDE requires these software packages.

Will my users / customers need the .NET runtimes / SDK in order to run my apps built with Delphi?

No. Applications produced with Delphi 2010 do not require any .NET runtime support. The product produces pure native Windows applications.

What are the differences between the ER/Studio Developer Edition data modeling capabilities in Delphi Architect and the standard ER/Studio product?

The ER/Studio data modeling and visualization in Delphi Architect is a subset of the full ER/Studio. Delphi Architect doesn't include metadata import/export capabilities or access to ER/Studio team repository servers. It includes limited reporting functionality (HTML only). The ER/Studio functionality in Delphi Architect supports a specific set of databases in line with those supported by dbExpress, while the full ER/Studio products offer flexible configurations for those databases and more.

Can I install Delphi 2010 on a machine with previous versions of RAD Studio, Delphi or C++Builder on it?

Yes, Delphi 2010 coexists nicely with earlier versions of RAD Studio, C++Builder and Delphi.

Are there new COMPILERVERSION and RTLVERSION values defined for Delphi 2010?

Yes. For Delphi 2010, COMPILERVERSION is set to 21.0, and RTLVERSION is set to 21.0.
