Great job, though I couldn't get any of the C# code to convert to VB.NET without numerous errors. I just wrote a function from scratch instead:


VB.NET code to get a QR image:

Private Function GenerateQRCode(URL As String, DarkColor As System.Drawing.Color, LightColor As System.Drawing.Color) As Bitmap
Dim Encoder As New Gma.QrCodeNet.Encoding.QrEncoder(Gma.QrCodeNet.Encoding.ErrorCorrectionLevel.L)
Dim Code As Gma.QrCodeNet.Encoding.QrCode = Encoder.Encode(URL)
Dim TempBMP As New Bitmap(Code.Matrix.Width, Code.Matrix.Height)
For X As Integer = 0 To Code.Matrix.Width - 1
For Y As Integer = 0 To Code.Matrix.Height - 1
If Code.Matrix.InternalArray(X, Y) Then TempBMP.SetPixel(X, Y, DarkColor) Else TempBMP.SetPixel(X, Y, LightColor)
Next
Next
Return TempBMP
End Function
