>I am afraid it is easier to make use of a ready-2-use application like e.g. http://www.qurify.com/nl/ (translate from Dutch to your own language)

Thank you for the link.
This can be used in VFP application by sending http get request to this web site and
parse returned html to get QR image.

This method requires internet connection.

How to implement this without requiring internet connection?
For example to call dll file or use RUN command to run some exe file and receive returned image in
VFP application.
