UPC-A Size Setting with C#, VB.NET Class in ASP.NET

Install UPC-A Barcode Creator Component into ASP.NET Projects

  1. 1.
  2. 2.
    Add reference: Add "KeepAutomation.Barcode.Web.dll" to your ASP.NET project reference
  3. 3.
    Add to toolbox: To add BarcodeControl to your ASP.NET toolbox
Copy the free C#/ VB.NET barcode syntax onto you forms to produce, string a UPC-A in ASP.NET web pages/ website:
using KeepAutomation.Barcode.Bean;
BarCode barcode= new BarCode();
barcode.Symbology= KeepAutomation.Barcode.Symbology.UPCA;
barcode.CodeToEncode = "12345678901";
Dim barcode As KeepAutomation.Barcode.Bean.BarCode = New KeepAutomation.Barcode.Bean.BarCode

barcode.Symbology= KeepAutomation.Barcode.Symbology. UPCA
barcode.CodeToEncode = "12345678901"

Creating UPC-A Barcode with Pixel as Unit of Measure

BarcodeUnit (URL: barcode-unit; Default: Pixel): it is the unit measurement for all size related settings in UPC-A 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

Adding EAN-2 & EAN-5 Barcodes as Supplement for UPC-A Barcode

Symbology (URL: symbology; Default: Code128Auto): it is used for changing barcode types.

SupplementCode(URL: supplement-code; Default: ""): it is used for encoding supplementary data.

SupplementHeight (URL: supplement-height; Default: 0.8f): it is the height of bar in supplementary symbol EAN-2 or EAN-5.

SupplementSpace (URL: supplement-space; Default: 15): it is used for changing space between UPC-A symbol and supplementary symbol EAN-2 or EAN-5.
barcode.Symbology = KeepAutomation.Barcode.Symbology.UPCASup2;
barcode.SupplementCode = "12";
barcode.SupplementHeight = 0.7;
barcode.SupplementSpace = 20;
barcode.Symbology = KeepAutomation.Barcode.Symbology.UPCASup2
barcode.SupplementCode = "12"
barcode.SupplementHeight = 0.7
barcode.SupplementSpace = 20

Drawing UPC-A with Specified X and Y Dimension

X (URL: x; Default: 1): it is the width of the narrow bar in UPC-A barcodes.

Y (URL: y; Default: 50): it is the height of bars in UPC-A barcodes.
barcode.X = 3;
barcode.Y = 75;
barcode.X = 3
barcode.Y = 75

Generating UPC-A with Fixed BarCodeWidth and BarCodeHeight

BarCodeWidth (URL: barcode-width; Default: 0): it is the barcode width of UPC-A barcodes.

BarCodeHeight (URL: barcode-height; Default: 0): it is the barcode height of UPC-A barcodes.
barcode.BarCodeWidth = 200;
barcode.BarCodeHeight = 75;
barcode.BarCodeWidth = 200
barcode.BarCodeHeight = 75

Creating UPC-A with Specific Quiet Margin

TopMargin (URL: top-margin; Default: 0): it is the barcode image top margin in UPC-A barcodes.

BottomMargin (URL: bottom-margin; Default: 0): it is the barcode image bottom margin in UPC-A barcodes.

LeftMargin (URL: left-margin; Default: 0): it is the barcode image left margin in UPC-A barcodes.

RightMargin (URL: right-margin; Default: 0): it is the barcode image right margin in UPC-A 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
