Questions tagged [delphi-7]

Delphi 7, released in August 2002, is a version of Delphi for Windows 32 bit.

Delphi 7 (codename: Aurora) is a specific version of Delphi. Always use the tag alongside this tag.

It was released in August 2002, became the standard version used by more Delphi developers than any other single version. It is one of the most successful IDEs created by Borland because of its stability, speed and low hardware requirements, and remained in active use as of 2011. Delphi 7 added support for Windows XP Themes, and added more support for building Web applications. It was the last version of Delphi which could be used without mandatory software activation.

Its release immediately preceded a period of turbulence in the history of Borland/CodeGear/Embarcadero that, combined with Delphi 7's robustness, contributed to its widespread use and longevity. In this regard, Delphi 7 can be considered the counterpart to MSVC6.

Delphi 7 introduced full support for XP themes, probably the most significant enhancement over Delphi 6.

Delphi 7 was preceded by Delphi 6 and succeeded by Delphi 8 (Codename: Octane).

Editions

Borland Delphi 7 Studio was released in four different editions:

  • Architect
  • Enterprise
  • Professional
