Install QR Code Barcode Generator Control into .NET Projects
1.
2.
Add reference: Add "KeepAutomation.Barcode.Web.dll" to your ASP.NET project reference
3.
Add to toolbox: To add BarcodeControl to your ASP.NET toolbox
Copy those following C# or VB.NET barcode onto you forms to produce a QR Code object in ASP.NET:
using KeepAutomation.Barcode.Bean;
BarCode barcode= new BarCode();
barcode.Symbology= KeepAutomation.Barcode.Symbology.QRCode;
barcode.CodeToEncode = "QR Code";
barcode.generateBarcodeToImageFile("C://barcode-qrcode-csharp.gif");
Dim barcode As KeepAutomation.Barcode.Bean.BarCode = New KeepAutomation.Barcode.Bean.BarCode
barcode.Symbology= KeepAutomation.Barcode.Symbology.QRCode
barcode.CodeToEncode = "QR Code"
barcode.generateBarcodeToImageFile("C://barcode-qrcode-vbnet.gif")
A professional QR Code encoder component SDK library, which allows ....

BarcodeUnit (URL: barcode-unit; Default: Pixel): it is the unit measurement for all size related settings in QR Code barcodes. User may change it with "Pixel", "Inch" and "Cm". Replace sample code with following one:
barcode.BarcodeUnit = KeepAutomation.Barcode.BarcodeUnit.Pixel;
barcode.BarcodeUnit = KeepAutomation.Barcode.BarcodeUnit.Pixel
Drawing QR Code Barcode with Specified Version
QRCodeVersion (URL: qrcode-version; Default: V1): it is used for setting QR Code version from 21x21 (V1) to 177x177 (V40). Replace sample code with following one:
barcode.QRCodeVersion = KeepAutomation.Barcode.QRCodeVersion.V1;
barcode.QRCodeVersion = KeepAutomation.Barcode.QRCodeVersion.V1
Creating QR Code with Defined Bar Width & Height (X & Y)
X (URL: x; Default: 1): it is the width of the narrow bar in QR Code barcodes
Y (URL: y; Default: 50): it is the height of bars in QR Code barcodes.
barcode.X = 3;
barcode.Y = 3;
barcode.X = 3
barcode.Y = 3
Printing QR Code with Fixed BarCodeWidth and BarCodeHeight
BarCodeWidth (URL: barcode-width; Default: 0): it is the barcode width of QR Code barcodes.
BarCodeHeight (URL: barcode-height; Default: 0): it is the barcode height of QR Code barcodes.
barcode.BarCodeWidth = 200;
barcode.BarCodeHeight = 75;
barcode.BarCodeWidth = 200
barcode.BarCodeHeight = 75
Barcoding QR Code Quiet Zones/ Margin
TopMargin (URL: top-margin; Default: 0): it is the barcode image top margin in QR Code barcodes.
BottomMargin (URL: bottom-margin; Default: 0): it is the barcode image bottom margin in QR Code barcodes.
LeftMargin (URL: left-margin; Default: 0): it is the barcode image left margin in QR Code barcodes.
RightMargin (URL: right-margin; Default: 0): it is the barcode image right margin in QR Code barcodes.
barcode.TopMargin = 8;
barcode.BottomMargin = 8;
barcode.LeftMargin = 6;
barcode.RightMargin = 6;
barcode.TopMargin = 8
barcode.BottomMargin = 8
barcode.LeftMargin = 6
barcode.RightMargin = 6
QR Code Size Setting with Drag & Drop BarcodeControl
1.
In "Choose Toolbox Items" form, click button "Browse...", and select KeepAutomation.Barcode.Web.dll
2.
Now you'll see BarCodeControl in your toolbox
3.
Drag and drop the BarCodeControl into the Forms and a Codabar image is generated
4.
Find barcode setting panel, choose "Symbology" to "QRCode" and write down encode data
5.
Set "BarcodeUnit" to "Pixel", and "QRCodeVersion" to V10
6.
Set "X" to 3, "Y" to 3; Set "BarcodeWidth" to 200 and "BarcodeHeight" to 75
7.
Set "TopMargin" & "BottomMargin" to 8; and set "RightMarign" & "LeftMargin" to 6
8.
A QR Code barcodes with different customized size occurs
QR Code Size Setting in Internet Information Service (IIS)
1.
Copy folder "barcode" in your download the trial package to your IIS web application folder
2.
Create a virtual directory, named "barcode", and link to your just copied "barcode" folder
