I am trying to create an application using VBA that will create a QR Code, based off of some text, that has both numbers and letters. I believe that I have been succesful in encoding the proposed data using the Alphanumeric mode of 2Q. I am trying to base this application off of the International Standard ISO/IEC 18004:2000(E) that explains the algorythm, but, I am starting to run into problems has to how to generate the error correction coding (sect 8.5.2).

Is there a QR Code Class for VBA that might be able to help me. Does anyone have some example code that I can look at? How does this class use the Reed-Solomon to generate the error corrections?

Thank you,
