I don't have any VB.NET code, but here's a sample C# method that will generate a PNG file and save it:

        public void Write(string barcodeText, string fileName, int width, int height)
        {
            MultiFormatWriter zx = new MultiFormatWriter();
            var barcode = zx.encode(barcodeText, BarcodeFormat.QR_CODE, width, height);
            var bitmap = new Bitmap(barcode.Width, barcode.Height);

            for (int y = 0; y < barcode.Height; y++)
            {
                for (int x = 0; x < barcode.Width; x++)
                {
                    int grayValue = barcode.Array[y][x] & 0xFF;

                    bitmap.SetPixel(x, y, (grayValue == 0 ? Color.Black : Color.White));
                }
            }

            bitmap.Save(fileName, ImageFormat.Png);
        }
