The time has come for KRENTO to be released as open source .You can find the source code on Google Code site: https://code.google.com/p/krento After 4 years of hard work I understood that I can't continue the development of such a big project alone. I hope that other developers will show the interest of giving the boost to this project. More information about Krento project is available on http://users.telenet.be/serhiy.perevoznyk/krento.html

The new version of Quricol library is available for download. Download :  https://github.com/perevoznyk/quricol Update from 07.05.2012 The error correction level is changed to high.

Krzysztof Michalowski modified the code to load library dynamically. This allows you to run a program when there is no library. Here is the code provided to me by Krzysztof. unit QuricolCode; interface uses Windows, SysUtils, Classes, Graphics, Dialogs; type TQRCode = class public class procedure GenerateBitmap(const FileName : string; const Text : string; Margin : integer = 4; PixelSize : integer = 3); class procedure GeneratePng(const FileName : string; const Text : string; Margin : integer = 4; PixelSize : integer = 3); class function GetBitmap(const Text : string; Margin : integer = 4; PixelSize : integer = 3) : TBitmap; class procedure GetPng(Stream : TStream; const Text : string; Margin : integer = 4; PixelSize : integer = 3); end; implementation { TQRCode } class procedure TQRCode.GenerateBitmap(const FileName, Text: string; Margin, PixelSize: integer); type TGenerateBMPWProc = procedure (fileName: PWChar; text : PWCh...

Last year I published the Quricol library for Delphi 2010 or better, but some users still need the support for older Delphi versions. As a result I made an update to Quricol library with support not only the Unicode, but also ANSI Delphi code. //=============================================================================== // Copyright (c) Serhiy Perevoznyk.

Quricol is an open source freeware QR code generator library for C++, Microsoft .NET and Delphi based on qrencode - QR Code encoder by Kentaro Fukuchi.The library contains methods to save the generated image to Bitmap or PNG file or generate images on-fly and save it to the stream. Both 32 and 64 bits compiled versions available along with source code. Download :  https://github.com/perevoznyk/quricol A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional code).

Recently I decided to update one of my Delphi applications and make it more shiny when running on Windows 7. I looked up in the list of the new Windows 7 features and selected the Windows 7 taskbar Jump List as a nice feature for my application. As of Windows 7, the taskbar has been extended with a possibility to create a list of destinations and common tasks associated with an application.This is the application's Jump List. The Jump List is available whether the taskbar button is in a launcher state (the application isn't running) or whether it represents one or more windows. As a result of this work I made a Delphi 2010 library for easy manipulating of Windows 7 Jump List. You can download the full source code here: http://1drv.ms/1iWeIDJ The Jump List class is similar to Microsoft .NET 4.0 JumpList class TJumpList = class sealed ... public constructor Create; destructor Destroy; override; procedure Clear; procedure AddToRecentCategory(ItemPath...

File associations provide a straightforward and useful way for users and developers to customize the Shell's treatment of defined file types. Application developers can use file associations to link an application to one or more desired file types, and customize the Shell's treatment of that application's file type. For example, when the application installs, it can check for the existence of the appropriate file associations, and either create or override them as appropriate. The file association can then cause the Shell to display custom icons for files of the given types. The file association can also control how the Shell interprets user input for a file of a given type. For example, when a user double-clicks a file, the Shell launches the application and uses it to open the file. The following Delphi class can be used to associate the application with the given file extension and compatible with Windows XP, Vista and Windows 7. // --------------------------------...

An application can monitor the contents of a file by using change notifications. unit FileWatch; interface uses Windows, SysUtils, Classes; type TFileWatch = class(TThread) private FFileName : string; FOnFileChanged: TNotifyEvent; FHandle : THandle; FLastTime : TFileTime; FActive : boolean; procedure ReleaseHandle; procedure AllocateHandle; procedure SetFileName(const Value: String); protected procedure Execute; override; procedure Notify; public constructor Create; destructor Destroy; override; procedure Suspend; procedure Resume; procedure Reset; published property OnNotify: TNotifyEvent read FOnFileChanged write FOnFileChanged; property FileName: String read FFileName write SetFileName; property LastTime: TFileTime read FLastTime write FLastTime; property Active: boolean read FActive write FActive; end; implementation resourcestring SErrAllocHandle = 'Could no...

Today I made a new release of PHP4Delphi . Download version 7.2: http://sourceforge.net/projects/psvlib/files/PHP4Delphi/PHP4Delphi%207.2/php4delphi.7.2.zip/download  Some time ago the development of PHP4Delphi was frozen, but meanwhile I received a lot of questions related to compatibility with latest versions of Delphi and PHP. Finally I decided to make a new release with support of Delphi starting from Delphi 5 till Delphi 2010 and PHP 5.3.0 (both releases for Visual Studio 9 and Visual Studio 6).

It's the real Comedy of Errors :)  Recently I looked in Google and was surprised how many links pointed to one of the products or the name is mentioned somewhere on the forum when the author means another product. I do understand now CodeGear's point of view (see my second post), but the situations remains the same. I feel that mostly PHP developers use wrong name, because Delphi developers know the difference between "Delphi for PHP" and PHP4Delphi. The best description of this disambiguation was given by Jonathan Benedicto: "Delphi For PHP can run Delphi code, because Delphi For PHP can run PHP code and because PHP code can run Delphi code. This is because PHP can run Delphi code, because a PHP extension can be written in Delphi, using PHP For Delphi's PHP extensions development framework. So, using Delphi For PHP, which, written in Delphi, runs PHP code, using PHP For Delphi, that PHP code, running in Delphi For PHP, can call a PHP extension being PHP...

Delphi for PHP uses PHP4Delphi  I know many commercial products that use PHP4Delphi, but the fact that it used by my favorite company is most important for me. For more information about Delphi for PHP please visit Embarcadero site .
