Hello Fellows!
I need to generate a QR Code with more than 256 characters. But is not possible.
I did some debugging and I found the problem in the BarCodeLibrary.dll

Is there any solution that i didn't see?

As I know, the maximum QR Code symbol size, in Version 40 and error correction level (L) can encode:
  • numeric data: 7,089 characters
  • alphanumeric data: 4,296 characters
  • Byte data: 2,953 characters
  • Kanji data: 1,817 characters
So, suggest you make sure your input data is correct. QR Code is capable of encoding above chars, as well as nine other characters: space, $ % * + - . / : ). Generally, Kanji characters in QR Code 2005 can be compacted into 13 bits.

Hope this help with your issue.

Best regards,

But the problem isn't the QR Code. But the VFP string. It doesn't accept to send more then 255 characters.
