VG Library II is a component collection for Borland Delphi and C++Builder. It includes more than 70 components for fast and robust application development. There are controls, data controls and data access components available to cover the wide range of tasks developers work on every day.

The library includes date, time and calculator edit controls; editors with RegEx-style picture mask support; file system and gradient controls; property storage framework; tray icon, threading, multi-language and animation components. The data acess components introduce the extended set of functionality for BDE, ADO and InterbaseExpress and implement the support of macro substitution, SQL scripts and design-time expressions. There is more.

The library is designed to provide you with the maximum functionality in every component and you will be pleased to discover all these options. It is based on the experience of many developers. We tried to do our best. Here you are.

Platforms supported: Delphi 5, Delphi 6, Delphi 7.
C++Builder support is temporary available in 2.60 only (C++Builder 5.0)!

VG2 Data Access

VG2 Data Access component set includes the wide range of data access components which extend functionality of standard data access components and provide the following features: Macro expansion support. Developers can change the text of SQL statement using macro substitutions. SQL scripts. Executes multiple SQL statements against BDE, ADO or InterBase databases. Codeless Fields initialization. The DefaultExpression property of TField components will initialize the values of fields for new records. The syntax for DefaultExpression is compatible with the Filter property and may include arithmetic, string, logic operators and a number of functions. User-defined constraints for fields and records. The ConstraintExpression and ConstraintErrorMessage properties allows to check the validity of user input. Codeless calculated fields. The calculated fields can be calculated by DefaultExpression property without writing code. The support of Tvg2DBNavigator environments such as applying filters and sort order to SQL statement.
