var writer = new BarcodeWriter(); writer.Format = BarcodeFormat.QR_CODE; writer.Options = new ZXing.Common.EncodingOptions
Using COM wrapper:
It handles many different barcode types (not just QR) and offers extensive support for sizing, colors, and different output formats (PNG, EMF, etc.).
: It is a pure VB6 implementation ( mdQRCodegen.bas ) that does not require installing third-party runtimes or registering ActiveX components.
Requires administrative privileges for deployment and registration.
A modern alternative often used when Google's legacy Chart API is unavailable.
Compile this code into a Class Library project (e.g., QRHelper.dll ) using Visual Studio (targeting .NET Framework 4.x for COM compatibility).
