How to Generate Barcodes in .NET Class or .NET Console Application?
Install .NET Barcode DLL
Add Reference BarcodeLib.Barcode.ASP.NET.dll or BarcodeLib.Barcode.WinForms.dll to your project. There's no need to copy barcoding dll to your project bin folder because Visual Studio will do it for you during project compilation time.
Implementation
The following C#.net code illustrates how to generate a 1d (linear) barcode using a C# class.
BarcodeLib.Barcode.Linear barcode = new BarcodeLib.Barcode.Linear();
// 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);
How to Generate Barcodes in ASP.NET Web Sites?
There are two methods to create barcode images in your ASP.NET web applications.
The Simplest way is to stream barcode image using our Buildin ASP.NET Barcode Application.
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=7&Data=CODE39-123456789012
To create barcode image in your aspx or html page, you need pass the url to IMG tag src value. For linear barcode: <img src="http://YourDomain:port/barcode/linear.aspx?Type=7&Data=CODE39-123456789012" /> or for Data Matrix barcode <img src="http://YourDomain:port/barcode/datamatrix.aspx?Data=BarcodeLib12345678&ModuleSize=4&LeftMargin=8&RightMargin=8&TopMargin=8&BottomMargin=8" /> or for PDF417 barcode <img src="http://YourDomain:port/barcode/pdf417.aspx?Data=123456789&ModuleSize=3&LeftMargin=6&RightMargin=6&TopMargin=6&BottomMargin=6" /> or for QRCode barcode <img src="http://YourDomain:port/barcode/qrcode.aspx?Data=0123456789&ModuleSize=3&LeftMargin=12&RightMargin=12&TopMargin=12&BottomMargin=12" /> This method will not generate any barcode images in your IIS server side.
The second method is to generate barcode images through ASP.NET Web Form controller.
Install ASP.NET Barcode Library Controller to your ASP.NET project.
Add Reference BarcodeLib.Barcode.ASP.NET.dll to your project. There's no need to copy barcoding dll to your project bin folder because Visual Studio will do it for you during project compilation time.
Add ASP.NET barcode library dll to your Visual Studio Toolbox.
Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.
Right click Toolbox, and click menu Choose Items...
Goto .NET Framework Components tab.
If no BarcodeLib component found, click Browse... button and select BarcodeLib.Barcode.ASP.NET.dll file.
Then sort "Namespace" column. You will find 4 components from BarcodeLib.Barcode.
Check component LinearASPNET, and its namespace is BarcodeLib.Barcode.
Check component DataMatrixASPNET, and its namespace is BarcodeLib.Barcode.
Check component PDF417ASPNET, and its namespace is BarcodeLib.Barcode.
Check component QRCodeASPNET, and its namespace is BarcodeLib.Barcode.
Click "OK" button, you will find four components under "General": LinearASPNET, DataMatrixASPNET, PDF417ASPNET, QRCodeASPNET.
Go to "barcode" folder in the trial package, and then copy files "linear.aspx", "linear.aspx.cs", "datamatrix.aspx", "datamatrix.aspx.cs", "pdf417.aspx", "pdf417.aspx.cs", "qrcode.aspx", "qrcode.aspx.cs" to the same folder as your aspx page, which will generate barcodes.
You can drag LinearASPNET on your aspx page, and change barcode setting through properties window.
Run the project. You will find barcode images generated in your aspx pages.
How to Generate Barcodes in .NET Windows Forms Application?
Add Reference BarcodeLib.Barcode.WinForms.dll to your project. There's no need to copy barcoding dll to your project bin folder because Visual Studio will do it for you during project compilation time.
In your .NET windows project, right click mouse over Refereces in your Solution Explorer window. Then click menu "Add Reference ...".
Add BarcodeLib.Barcode.WinForms.dll to your project.
Add .net winforms barcode library dll to your Visual Studio Toolbox.
Open Toolbox in Visual Studio. Click menu View, and check submenu Toolbox.
Right click Toolbox, and click menu Choose Items....
Goto .NET Framework Components tab.
If no BarcodeLib component found, click Browse... button and select BarcodeLib.Barcode.WinForms.dll file.
Then sort "Namespace" column. You will find 4 components from BarcodeLib.Barcode.
Check component LinearWinForm, and its namespace is BarcodeLib.Barcode.
Check component DataMatrixWinForm, and its namespace is BarcodeLib.Barcode.
Check component PDF417WinForm, and its namespace is BarcodeLib.Barcode.
Check component QRCodeWinForm, and its namespace is BarcodeLib.Barcode.
Click "OK" button, and you will find four components under "Common Controls": LinearWinForm, DataMatrixWinForm, PDF417WinForm, QRCodeWinForm.
Now you can see the component displayed on Toolbox. Then, you can drag LinearWinForm on your form and change barcode setting through properties window.
