Control for Making QR Code Bar Code

Adam Hartman

Hey, I need a custom control for Windows Forms programming. In my project, a graphics object carrying a dynamic 2D QR Code need to be generated on the form. I'm not sure if there is any custom control could be used to make this happen. If any recommendation, the SDK should be compatible with C# window forms.

You can generate qr code barcode in .net projects using C# or VB class by adding reference ("KeepAutomation.Barcode.Windows.dll" or "KeepAutomation.Barcode.Web.dll") to your Visual Studio project and compiling the following C# and VB sample codes.
C# Sample code

using KeepAutomation.Barcode.Bean;

BarCode qrcode = new BarCode();
qrcode.Symbology = KeepAutomation.Barcode.Symbology.QRCode;
qrcode.QRCodeVersion = KeepAutomation.Barcode.QRCodeVersion.V10;
qrcode.QRCodeECL = KeepAutomation.Barcode.QRCodeECL.M;
qrcode.CodeToEncode = "0123456789";
qrcode.X = 3;
qrcode.Y = 3;
qrcode.TopMargin = 12;
qrcode.BottomMargin = 12;
qrcode.LeftMargin = 12;
qrcode.RightMargin = 12;
qrcode.QRCodeDataMode = KeepAutomation.Barcode.QRCodeDataMode.Auto;
qrcode.generateBarcodeToImageFile("c://qrcode-csharp.png");

VB Sample code

Dim qrcode As KeepAutomation.Barcode.Bean.BarCode = New KeepAutomation.Barcode.Bean.BarCode

qrcode.Symbology = KeepAutomation.Barcode.Symbology.QRCode
qrcode.QRCodeVersion = KeepAutomation.Barcode.QRCodeVersion.V10
qrcode.QRCodeECL = KeepAutomation.Barcode.QRCodeECL.M
qrcode.CodeToEncode = "0123456789"
qrcode.X = 3
qrcode.Y = 3
qrcode.TopMargin = 12
qrcode.BottomMargin = 12
qrcode.LeftMargin = 12
qrcode.RightMargin = 12
qrcode.generateBarcodeToImageFile("c:/qrcode-vbnet.png")

Actually, apart from the option to use commercial C#.NET barcode creator add-on, you can also try some free public sources, like zxing, which has been used by many developers to generate QR code barcode image.

By the way, google chart API may be also an option.

Here is a free version of barcode SDK compatible with C# window forms, supporting to create QR Code, Data Matrix, PDF417 2D barcodes. I tried it in my own program. The created barcode can be clearly seen and easily read.

How to make QR Code in C# window forms? There are a few steps you should know:
1,Install C# window forms Barcode Control;
2,Add C# window forms Barcode Control onto your .NET Visual Studio Toolbox;
3,Copy "qrcode.aspx" and "qrcode.aspx.cs" to the folder where your aspx pages are generating barcodes;
4,Drag and drop a fine 3rd party QR Code control into the Forms;
5,Run the website and you will see a barcode image generated;

I hope it helps. Good luck.

Best regards,
Arron
