Open Source .NET QRCode Library
By admin on Sep 13, 2007 in .NET, Programming, open source
Today I released the source code for the .NET QRCode library.
.NET QRCode library is a .NET component that can be used to encode and decode QRCode. QRCode is a 2 dimensional bar code that originated in Japan. Nowadays it is widely used in a wide range of industries, e.g. for vehicle parts tracking and inventory management.
QRCode Library provides functions to:
- Encode content into a QR Code image which can saved in JPEG, GIF, PNG, or BITMAP formats
- Decode a QR Code image
The library can be used in any .NET 2.0 Windows Application, ASP.NET web application or Windows Mobile device application.
Some sample screenshots are displayed below:

More details on the component can be found on the website.

I am interested in QR Codes to automate some realtime tracking needs.
However, I have seen a system running on a Windows Mobile system that aquired the barcode in real-time via the built-in video capture (video, not pictures).
I would like to build a custom app similar both on Windows Vista (using a laptop’s built in webcam) and Windows Mobile (using built in webcam).
Can you make any suggestions on where to start with this? The video capture is the show stopper.
