Modern software design

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.

For one of my internal projects I made a small C++ library for working with different types of streams. The main library classes are CMemoryStream, CFileStream and CResourceStream. The source code is available for download from my website: http://users.telenet.be/serhiy.perevoznyk/download/GevixLib.zip
