How to Create Code 39 Image in ASP.NET Web Applications in C# Generator?
With this C# Code 39 generator component, you can stream Code 39 barcode images in ASP.NET in two ways.
Method 1: The simplest way for Code 39 barcode generation is through BarcodeLib Buildin ASP.NET Barcode Application.
Unzip the downloaded evaluation package, and copy barcode folder and its contents to your IIS folder, eg. C:\inetpub.
Create a new virtual directory in your IIS, name it "barcode", and connect it to the above "barcode" folder in inetpub.
Restart IIS for a barcoding test.
To test your installation, open your web browser and navigate to: http://YourDomain:port/barcode/linear.aspx?Type=7&Data=CODE39-39393939&LeftMargin=8&RightMargin=8 For further Code 39 barcode setting, please view more web stream Code 39 URL parameters here: Code 39 .NET Generator DLL Property Settings.
To insert this Code 39 image in your aspx or html page, simply pass the url to IMG tag or src value. For example: <img src=http://YourDomain:port/barcode/linear.aspx?Type=7&Data=CODE39-39393939&LeftMargin=8&RightMargin=8 /> This method will not generate any barcode images in your IIS server side.
Method 2: Another method is to generate Code 39 barcodes through ASP.NET web form controller.
Intall ASP.NET barcode controller to your barcoding project by adding reference.
Add barcode library to your Visual Studio toolbox.
Open your unzipped trial package, and copy files "linear.aspx", "linear.aspx.cs" to the aspx page, in which you will be generating Code 39 images.
Now you can drag LinearASPNET to your ASP.NET web site, and change Code 39 settings through properties window on the right or use above free C# source code.
Debug and you will see the Code 39 barcode generated on your aspx pages.
