dBarcode .NET products are designed to work with Visual Studio 2005-2015 and require the .NET Framework 2.0 (or later) to be installed on any computer using the components. Example code for Windows Forms is provided with each control and component for users of Visual Basic .NET and C#. An example ASP.NET application is included and may be seen online here.

Using on ASP.NET pages
There are many possible approaches to generating barcode images for ASP.NET pages. Whatever method is chosen it is important to ensure that the image is created at a higher graphics resolution than the normal 96 dpi used for web images - because the width of the bars is important.
One method, suitable for use when the barcode is to be data-dependent, is to use two aspx files, one which creates a memorystream barcode image using one of the dBarcode.NET components and then uses a dummy ASP.NET page as the SRC for an IMG tag to display the image at the correct size, eg.
<script language="vb" runat="server">
sub Page_Load(Sender As Object, E As EventArgs)
…………………..
m_barcode.Unit = GraphicsUnit.Inch
m_barcode.XUnit = 0
m_barcode.Font=m_Font
m_barcode.Orientation=0
m_barcode.AutoCheckdigit=TRUE
m_barcode.BarcodeHeight = tht ' desired height in inches
m_barcode.BarcodeWidth = twd ' desired width in inches
m_barcode.CodeTypeValue = 8
m_barcode.caption = Session("xx")
Session("ms")=m_barcode.sBarcode(300,300,System.Drawing.Imaging.ImageFormat.Png)
if Session("ms").Length>0 then
Session("ht")=m_barcode.ImageHeight*96/300 ' adjust size for the desired image resolution
Session("wd")=m_barcode.ImageWidth*96/300
end if
</script>
</head>
<BODY>
<H1>dLSoft dBarcode.NET - on ASP.NET</H1>
<IMG SRC="page2.aspx" HEIGHT=" <% =Session("ht") %> " WIDTH=" <% =Session("wd") %> ">
<p> dBarcode.NET components can generate barcode images in BMP, GIF, PNG, JPG, TIF and WMF formats, and for more than 50 barcode types.

The Session variables ht and wd contain the actual sizes at which the barcode image is to be drawn on the web page. These are calculated when the page is loaded and used when the IMG SRC calls the second page.
The second file (page2.aspx) serves up the image at the correct size, eg.
<%@ LANGUAGE="VB"%>
<%
Response.ContentType="image/png"
Response.BinaryWrite(Session("ms").GetBuffer())
%>
