4. Write in the event:

ThoughtWorks.QRCode.Codec.QRCodeEncoder qr = new QRCodeEncoder ()

Qr.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE

Qr.QRCodeScale = 3

Qr.QRCodeVersion = 5

Qr.QRCodeErrorCorrect = QRCodeEncoder.ERROR_CORRECTION.M

/ / the above parameters are adjusted as needed

Image img

String Code = "text content to be written into QR code"

Img = qr.Encode (Code)

This.pictureBox1.Image = img
