Generate QR Codes in Access database report

Keywords: Access 365, QR Code

With Barcodesoft QRCode Web Service, users can generate QRCode (or any other barcode symbol) in Access database report.

No download needed! No 3rd-party software installation needed!

All you need is just internet access.

When you open the sample database, it will ask you whether to enable VBA codes. Please choose Enable Content.

Please create a "c:\temp" folder in your C Drive. All dynamic generated QRCode images will be saved in this folder.

Now, please open Forms and run Form1. Click "Download" button. It will automatically download all QR Code images to your "c:\temp" folder.

QR Code image file name will be saved to the attachment field of current record.

If you run report now, you will find each record has its own QR Code.

Now, let's look at the VBA codes
