Control for Making QR Code Bar Code

Question

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.
