QR Code reader tutorials? (C#)

[Trebor29]

Hi people,

Its that time again, the start of a new study year...

Does anyone know about QR Codes? I think that these are going to be the focus of my final year project dissertation, possibly their vulnerability regarding malicious content...! But I want / need to do some tutorials building some QR Code readers / generators (in C#, preferably Win.Mob.7 application ) to get a better understanding of how they work...

Has anyone got any ideas / links / research tip etc...?

Thank you!

Nipuna has added a nice tutorial for QR Code at https://robot.lk/viewtopic.php?f=13&t=2842. I have added some more information to that.

Source codes for .Net :
Open Source QRCode Library from CodeProject
QrCode from GoogleCode

I'm sure you'll be able to give a start with those code bases.

Thanks Saman,

There's a very good pdf on the "QR code from GoogleCode" link, Thanks...

Not looked too deep into the tutorials yet but they appear to be focused on QR code generation,,, not so much on building a QR code reader!?

Do you now where I might find a QR code reader app (mobile) tutorial...? Ive been searching but everythng seem to be focused towards the QR code generators!

Thanks again Saman,

It seems you didn't notice that the code project one supports decoding as well. Have a look again.
In addition to that, you might also be interested in following links.
libdecodeqr
iphone-qrcode
