Dave,
I played around a bit with QR codes last spring and what I planned to do
was write the QR code image to a file, then store the path/filename for
VFP to use for accessing/using the bitmap image.

Stephen,
That's what I am a little confused about. Yes I want to pass an image bac i.e I want to put an
Image on the report and make the source something like "=getQR(<parameters>)" where
getQR is a method in my ActiveX but for the life of me I can't find out exactly WHAT to send back
from the ActiveX... I've tried strings & streamed data but neither of them work.
I guess a goof old forage into the VFP API is called for but I find the
documentation sketchy to say the least
Thanks anyway,
Dave

Gary,
It isn't the QR codes that I have a problem with, I've sorted out all
the coding for that myself in C# so I can create, read and print them
no problem. I just want to be able to:
1. Pass the finished QR code (image) back to VFP from the ActiveX/DLL
so I can use it in reports as per standard VFP image control. i.e what
do I pass back? Memory Stream, blob string etc etc... I don't know.
2. Pass a document to my "ActiveX/DLL" and pass back the QR Code
content as a string. I can already do this if I just pass in the
location of the QR Code image to my ActiveX as I have worked out how
to expose properties and methods to VFP from it. I guess I could
convert the image to a string
FiletoStr() and pass that in for this purpose unless anyone else has
any better ideas.

-------------------
Can you make an image file to pass back? Not user that VFP can make one itself
so that raw data is not acceptable.
If you make the image can VFP catch a stream?
