If your application will always have internet access, using a REST API is the simplest method. This offloads the complex math of QR generation to a remote server.

For enterprise environments that require dedicated support or advanced features (like adding logos or specific error correction levels), ActiveX controls are a standard choice. GitHubhttps://github.com wqweto/VbQRCodegen: QR Code generator library for VB6/VBA

You can use the Chilkat VB6 API Examples to send a GET request to an endpoint like api.qrserver.com and save the resulting PNG or display it in a PictureBox . 3. Commercial ActiveX / OCX Controls

The most robust and portable way to handle QR codes in VB6 is through a "class" or "module" that implements the QR generation logic entirely in native code. This eliminates the need for registering external DLLs or requiring an internet connection.

An excellent open-source choice is the VbQRCodegen library on GitHub . It is based on the highly-regarded Nayuki QR library and is distributed as a single .bas module.

Although officially deprecated, it remains widely used for simple tasks. You can download the image using a simple HTTP request. Example URL: https://googleapis.com .

To generate a QR code in VB6, you typically have three main implementation paths: using a pure VB6 library (no dependencies), leveraging a web API, or using a third-party ActiveX/OCX control. 1. Pure VB6 Implementation (No Dependencies)

' In a form with an Image control named Image1 Set Image1.Picture = QRCodegenBarcode("https://example.com") Use code with caution. 2. Using Web APIs (Fastest Setup)
