Title: Saving QR Code to an ImageFile
Post by: de la Rosa on March 05, 2022, 05:18:04 PM

Hi,

In the below Code, the QR Code is generated in the Element defined by ElementID, how can I save the generated QR image to an image file on disk where it can be retrieved and displayed elsewhere?

    Glo:st.remove('<123>')
    Glo:st.remove('<125>')
    Glo:st.remove('<10>')
    Glo:st.remove('<13>')
     
    ElementData = 'QRDisplayForm?RefNo =' & p_web.GSV('RefNo') & '& CustID =' & p_web.GSV('CusttID')
     
    ElementID = 'Ticket_QR'
       
    p_web.script('generateQrCode('& '''' & CLIP(elementID) & '''' & ',' & '''' & Clip(ElementData) & '''' & ');')




TIA
Vic

?? maybe easier to use a library to generate the image on the server rather than with script on the browser ??

Yes, can you point me to an example I can refer to?

Hi Alberto,

Sorry, I'm not familiar on how to compile it without an *.app file. There are 2 project files but with no app files?

Will appreciate any help.

Thanks,
Vic

I recommend coming to a Wednesday Open webinar (www.clarionlive.com) so I can show you how to compile a project.
