i have a VB.net program set up that has a fully working webcam viewer and a QR code reader.
it does it using some Dll's i found.
now my problem.... the dll for the QRCode reader is a irritating evaluation version which keeps changing the first character of the scanned qrcode to a number.. (which incriments slowly obviously as some form or time trial)
does anyone know of a open source .net method of reading QRCodes or has a non evaluation Dll for my vb.net program to reference.
I don't know about VB.net specifically but ZBar is an open source barcode library that works on multiple platforms. You can see it being used for Bitcoin by the Electrum client with Python but it is written in C and works with many languages. You should check it out as maybe it can be used with VB.
http://zbar.sourceforge.net/This page has some info about making an import library for a DLL.
