VB6 may be old, but with creative integration techniques, it can still dance with the latest technologies. QR codes are just one example—once you master COM interop or API calls from VB6, you unlock a world of possibilities, from barcode scanners to REST APIs and cloud storage.

For y = 0 To qr.size - 1 For x = 0 To qr.size - 1 If qr.matrix(x, y) = 1 Then picBox.Line (x * scale, y * scale)-((x + 1) * scale, (y + 1) * scale), vbBlack, BF Else picBox.Line (x * scale, y * scale)-((x + 1) * scale, (y + 1) * scale), vbWhite, BF End If Next x Next y

You can also generate a QR code by calling a free web service like through the Chilkat API or standard WinHTTP calls to download the resulting image.

' Initialize encoder qr.ErrorCorrection = ecL ' Low error correction qr.QuietZone = 4 ' White border (modules) qr.Scale = 8 ' Pixels per module

For those wanting zero external dependencies, community-developed VB6 QR encoders exist. One notable example is the project (available on GitHub). It is a pure VB6 class module that implements the QR code specification for alphanumeric and byte mode up to version 10.
