Parse components v.1.0FNC 452 - 509 k 20 Apr 2011
By Yuriy Pisarev. The components are intended for Delphi developers and perform high-speed (about 10 million evaluations per second) mathematics and boolean calculations. All components are available for Delphi 5, Delphi 6, Delphi 7, Delphi 2005, Delphi 2006, Delphi 2007, Delphi 2009, Delphi 2010, Delphi XE.

Components and units, mentioned above, contain a number of high-speed simple methods having the singular input parameter of string type, which represents the mathematics expression, and returning the number (AsByte, AsInteger, AsBoolean, etc.). It makes possible using the parse components at any time without unnecessary understanding the internal parse mechanisms.

It is possible making a user-defined functions, variables, constants and types. It is also possible making a direct reference to the simple variable of type like Byte, Integer, etc. Each number is represented by structure able to keep the variable of almost any primitive type. Within the calculation process the numbers and their types are being changed to fit the execution result. It means that if we have an expression "(Byte 2) * (Byte 2)" then the result type is being set to Integer to fit the maximum possible value of two Byte type numbers multiplication. The numbers are being changed the same way when optimizing the expression.

The components are not free, except for using in science purpose - in this case the science license is required; the science license allows to declare the unlimited number of user-defined functions. There are no restrictions making impossible using the components for non-commercial purpose in case of having no license. The only limitation is the number of user-defined functions. In any case you are able to define as minimum as ten functions for free (non-commercial use only).

  Problem Solving with Delphi
This title includes a book and a CD. The purpose of the book is to use Delphi as a vehicle to introduce some fundamental algorithms and to illustrate several mathematical and problem-solving techniques. This book is therefore intended to be more of a reference for problem-solving, with the solution expressed in Delphi. It introduces a somewhat eclectic collection of material, much of which will not be found in a typical book on Pascal or Delphi. Many of the topics have been used by the author over a period of about ten years at Bond University, Australia in various subjects from 1993 to 2003. Much of the work was connected with a data structures subject (second programming course) conducted variously in MODULA-2, Oberon and Delphi, at Bond University, however there is considerable other, more recent material, e.g., a chapter on Sudoku. more... more...


  Develop and debug service applications easy then ever
SvCom is an integrated package of classes and tools for development of service applications and use of NT Security framework. Currently SvCom components work under all flavours of Windows.
  • Deploy NT Service applications under Windows 9x/ME and NT/ 2000/ XP/ 2003/ 2008/ Windows 7 (Unique feature!!!)
  • Develop and debug NT services using either Windows 95/98 or NT/ 2000/ XP/ 2003/ 2008/ Windows 7 - using the same classes and the same function calls (!!!)
  • Advanced service debugging (Extremely useful, when you service is not just "Hello, World!")
  • Many more features...
