Key Features of this Implementation
Generating QR codes in Visual Basic 6.0 requires external solutions, such as the open-source VbQRCodegen library, REST API calls for online functionality, or COM-based SDKs like ByteScout. The most common approach for offline applications is using the VbQRCodegen library, while APIs offer a lightweight, dependency-free alternative.
