How to generate barcode

Try to search for barcode library in google. You'll finds lot of them...

Extensive google investigation resulted in this[^].

hi,


Add a page(eg. barcode.aspx) ,


write this in code behind(barcode.aspx.vb) in page load,

have to download iTextsharp.dll

and use this namespace

Imports iTextSharp.text.pdf



  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim bc128 As New Barcode128() 'u can use 39 instead 128

       bc128.Code ="1234" ' Your value you can get from query string or session 
       Dim bc As System.Drawing.Image = bc128.CreateDrawingImage(System.Drawing.Color.Black, System.Drawing.Color.White)

       Response.ContentType = "image/gif"
       bc.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Gif)

   End Sub

in another page where u want bar code,

just place image control. pass image url to already written page.

Image1.ImageUrl = "BarCode.aspx"

now u can get ur barcode in the image control

regards,
pal

It is very simple.
download Barcode Font.as
Code 128
code 3 to 9
Code 39 etc.
Install these.
and set label font to these font ,barcode automatic generated.

blbl.Font = new System.Drawing.Font("Code 128", 30.75F);

you can use this method in MS word,or word pad ,Excel also.

and to read you again no need of any code if you are using USB barcode reader.
You can test this as put cusor in test box or notepad and read barcode by barcode reader.It read automatically.
