Language	Project /  Comment	Screenshot
Delphi 7	Stat. Stat analysis - Multivariate correlations, Principal component analysis,  Code:  (120 950 bytes). The program can be downloaded here. Theory.
Delphi 7	CardFile. Version 1.9 (2006.06.06). Tree View XML Card-index (Code bank, Cookbook, Address book, etc.). The program uses some code from the excellent Tutorial on TTreeView by Andre .v.d. Merwe .  Details and Tutorial, Code:  (61 259 bytes). The program can be downloaded here.
Delphi 4-7	Interface-based Delphi wrapper for SQLIte 3. Project Picture DB. Code: (~350KB), Demo: (~530KB). Description.
Delphi 4-7	Cubic Poynomial. Scientific programming tutorials. Delphi/Kylix Project. Code: (~7KB), Exe: (~200KB).
Delphi 4-7	Cubic Poynomial 2. Scientific programming tutorials. Delphi/Kylix Project. Code: (~7KB), Exe: (~250KB).
C++Builder 5+	Cubic Poynomial. Scientific programming tutorials. C++Builder/Kylix3 Project. Code: (~6KB).
Delphi 4-7	Orthogonal Poynomials. Scientific programming tutorials. Delphi/Kylix Project. Code: (~8KB), Exe: (~200KB).
Delphi 4-7	Electrochemical fit using Differential Evolution. Scientific programming tutorials. Delphi/Kylix Project. Code: (~30KB), Exe: (~280KB).
Delphi 6+	XSL Transformer. The program performs transformations from XML to HTML (or other types of documents) using XSL Templates: ( XML + XSL ) HTML. See the description for details. Code: (~60KB), Exe: (~460 KB).
Delphi 3+	TestTEA. The unit uTeaSet.pas implements TEA, XTEA, Block TEA and XXTEA algorithms. This is a direct translation from the original C code by David Wheeler & Roger Needham, Cambridge University Computer Lab: uTeaSet.pas. (9 KB).
Delphi 3+	PassMgr - a sample App for TEA. Code, Help:  (~ 50 KB), Exe: can be downloaded here.
Delphi 5+	GA_TSP. Genetic Algorithm for the Traveling Salesman Problem. This is an interface-based implementation (see details here)  of Dan Taylor's Evolutionary TSP Algorithm demo program. Code:   (46 KB), Exe:   (~190 KB)
Delphi 6+	Address book. Delphi 6 XML data binding wizards: Use and improvements.Details and Tutorial. Code: (~80 KB), Exe:   (340 KB).
Delphi 5+	FileDB. Remark 0: I would recommend Cary Jensen's "A ClientDataSet in Every Database Application" (and subsequent articles)  available now at Borland site. Tutorials for TClientDataSet, File management routines, XML. The program collects information about files. Code:   (28 KB), Exe:  (360 KB),   (540 KB with linked Midas.dll) Remark 1: in Delphi 5 the midas.dll is required to run the program.  Remark 2: in Delphi 6 midas.dll is linked to the exe if MidasLib  is included into uses clause.
Delphi 4+	FileTree. Tutorials for TTreeView, File management routines. The program displays and compares directories in two windows. Code:   (30 KB), Exe: (192 KB).   Remarks: - This project was inspired by excellent TreeView tutorial by  Andre v.d. Merwe  - it works for TreeNT by Mike Lischke as well  To Do: implement copy/delete functionality
