There are several QR code libraries available for VB6, but one of the most popular ones is the library. This library provides a simple and easy-to-use API for generating QR codes.

The above requires interactions with .NET objects, which runs fine inside VB6.

Using the VbQRCodegen library from wqweto , you can generate a QR code and display it in a standard Image control with just one line:

' Pad with 0s to fill capacity (Version 1-L = 152 bits data capacity approx) ' This simplified example truncates for brevity. In production, use specific padding bytes. End Sub

In a command prompt as Administrator:

' Set the QR code size and margin qrCode.Size = 200 qrCode.Margin = 4
