.NET UPC-E Generator for .NET, ASP.NET, C#, VB.NET

• 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

• Under downloaded trial package, copy barcode folder to your IIS folder, e.g. C:\Inetpub.
• Create a new virtual directory in IIS, named barcode, and link to the above "barcode" folder.
• Restart IIS.
• To test your installation, open your web browser and navigate to
  http://YourDomain:Port/barcode/linear.aspx?Type=UPCE&Data=123456
• To create barcode image in your aspx or html page, you need pass the url to IMG tag src value.
  
  For example:
  <img src="http://YourDomain:port/barcode/linear.aspx?Type=UPCE&Data=123456" />
  
  Using this method, it will not generate any barcode images in your IIS server side.

1. Install .NET Barcode Controller to your ASP.NET project.
   1. Add Reference BarcodeLib.Barcode.dll to your project.
      Do not copy the dll to the bin directory, Visual Studio will do so, during project compilation time.
2. Add barcode library to your Visual Studio Toolbox.
   1. Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.
   2. Right click Toolbox, click menu Choose Items...
   3. Goto .NET Framework Components tab.
   4. If no BarcodeLib component found, click Browse... button and select BarcodeLib.Barcode.dll file.
   5. Then sort "Namespace" column, you will find 8 components from BarcodeLib.Barcode.
   6. Check component LinearWebForm, and its namespace is BarcodeLib.Barcode.Linear
   7. Click "OK" button, you will find four components under "General": LinearWebForm.
3. Go to "barcode" folder in the trial package, copy file "linear.aspx" to the same folder as your aspx page, which will generate barcodes.
4. You can drag LinearWebForm on your aspx page in design view, change barcode setting through properties window.
5. Run the project, you will find barcode images generated in your aspx pages.

1. Add Reference BarcodeLib.Barcode.dll to your project. Do not copy the dll to the bin directory, Visual Studio will do so, during project compilation time.
   1. In your .NET windows project, right click mouse over Refereces in your Solution Explorer window. Then click menu "Add Reference ...".
   2. Add BarcodeLib.Barcode.dll to your project.
2. Add barcode library to your Visual Studio Toolbox.
   1. Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.
   2. Right click Toolbox, click menu Choose Items...
   3. Goto .NET Framework Components tab.
   4. If no BarcodeLib component found, click Browse... button and select BarcodeLib.Barcode.dll file.
   5. Then sort "Namespace" column, you will find 8 components from BarcodeLib.Barcode.
   6. Check component LinearWinForm, and its namespace is BarcodeLib.Barcode.Linear
   7. Click "OK" button, you will find the control under "Common Controls": LinearWinForm.
3. Now you can see the component displayed on Toolbox. You can drag LinearWinForm on your form, change barcode setting through properties widnow.

1. Add Reference BarcodeLib.Barcode.dll to your .NET project (ASP.NET website, Forms, any .NET project)
   In your .NET class.
   

   	BarcodeLib.Barcode.Linear.Linear barcode = new BarcodeLib.Barcode.Linear.Linear();
   	
   	barcode.Type = BarcodeType.UPCE;
   	
   	// should be 6 digits
   	barcode.Data = "123456";
   	
   	barcode.UOM = UnitOfMeasure.Pixel;
   	barcode.BarWidth = 1;
   	barcode.BarHeight = 80;
   	barcode.LeftMargin = 10;
   	barcode.TopMargin = 10;
   	
   	barcode.Format = ImageFormat.Png;
   	
   	// more barcode settings here
   	                        
   	// save barcode image into your system
   	barcode.drawBarcode("c:/barcode.png");
   	
   	// generate barcode & output to byte array
   	byte[] barcodeInBytes = barcode.drawBarcodeAsBytes();
   	
   	// generate barcode to Graphics object
   	Graphics graphics = ...
   	barcode.drawBarcode(graphics);
   	
   	// generate barcode and output to Bitmap object
   	Bitmap barcodeInBitmap = barcode.drawBarcode();
   	
   	// generate barcode and output to HttpResponse object
   	HttpResponse response = ...;
   	barcode.drawBarcode(response);
   	
   	// generate barcode and output to Stream object
   	Stream stream = ...;
   	barcode.drawBarcode(stream);
