I have a report which contains 6 fields and I want to create a QR code on the report that has the information from all 6 fields.

How can I do this?

Do you mean concatenated string?

If so you can do something like this in either your query or in an unbound textbox of the report:
[Text1] & [Text2] & [Text3] & [Text4] & [Text5] & [Text6]

Is that what you are after?

Actually, the text fields are "stacked" one on top of another.  I want the QR code to look the same.

I am not sure I understand. So you have the text fields stacked on top of another in your report, and you want them to have in one text field?

Maybe an example would help to give you better assistance.

You can use this executable to generate the code image from command line, using SHELL() in MsAccess.., based on a concatenated string of fields ..with a seperator, for example a comma.

http://code.google.com/p/qrencode-win32/downloads/list


..for example..
qrcode.exe -o test.png -s 5 -l H "John,Doe,800-867-9305,jdoe@gmail.com,12/12/1971"

You will have to know how to code in MsAccess, to both generate the image from shell command, and also insert the image onto the report.

All you need is to concatenate with a separator you can replace with a line feed when reading:

strQRToSend = Join(Array([Text1], [Text2], [Text3], [Text4], [Text5], [Text6]), ";")
 
Then to read and display:

strQR = <string received/decoded>

strQRStacked = Join(Split(strQR, ";"), vbCrLf)
