Generate QR Code in Crystal Report using VB.NET

Question

is there any way to generate QR Code from VB.NET into Crystal Reports ?

I have tried this tutorial : http://www.keepautomation.com/vbnet_barcode/qrcode.html

but always get error : "A required privilege is not held by the client."

Is there another plugin or whatever it is to generate QR Code from VB.NET into Cystal Reports ?

Answer 1

I wasn't able to find a native way to generate QR codes in crystal reports or VB, but I did find a way to link an image to a google API that generates QR Codes.

To use:

1. Insert a graphic to the report.
2. Right click on the image and click "Format graphic".
3. Click on the "Picture Tab".
4. Click on the formula edit button next to graphic location.
5. Add this code or reference a formula with this code in it.

6. Edit the variables as needed.
