The Internet Component Suite is composed of various Internet components and applications. It is distributed as freeware with full source code for all Delphi and C++Builder versions. The sample applications exists in two forms: Object Pascal for Delphi and C++ for C++Builder. The components are written in Object Pascal native VCL which can be compiled by Delphi as well as C++Builder. There is a wiki under construction here where you'll find valuable documentation.

ReportBuilder is the defacto standard for Delphi reporting solutions. Delphi developers have consistently voted ReportBuilder Product of the Year (1999 – 2002) and Best Reporting Tool (1999 – 2003). The genesis of ReportBuilder was the desire to deliver a product that does for Reporting what Delphi has done for Windows programming. In that spirit, ReportBuilder provides both a RAD environment and an object-oriented platform for solving the reporting equation.
