I am attaching a small Win32 Console application that shows how you can write a QR barcode using C DLL v18 L_BarCodeWrite function.

You can use the console application by passing two command line arguments:
1. Barcode data.
2. Target file name. The application will save the barcode to PNG image.

Thanks,

I have updated this project to use version 20 of our toolkit using Visual Studio 2017. This is also now configured to run in 64 bit mode as well. As before, to call this program from the command line you must provide it with a string that you wish to use as the barcode data, as well as a filename for the resulting image. The project is set up to use the string "LEADTOOLS" as the barcode data and save to C:\temp\QRbarcode.png.
