Output a PDF file in browser (creates PDF on fly)

Like the way .Net makes easier to do playying with files & objects, the ASP.Net objects are now more cool.

Can do a lot of things for you.

In my project, i have an request to query a pdf file from a location and then to show it into a browser as a PDF file, infact making it downloadable for a user. The following code do this all. It first make a request via WebClient .Net Framework class to a URL where the pdf is present and then downloads the whole data in a byte array and then output it using Response object. Its quite simple, just follow the following code…

In fact what i do, as i request the PDF file from a virtual directory which has integrated windows security, so in making the web client request i also passed the credential of a domain user.

________________________________________________________________

Dim remoteFilePath As String
Dim credCachae As New CredentialCache
Dim myWebClient As New WebClient

‘ PDF file path
remoteFilePath =
http://wajahatabbas.blogspot.com/billing/Bill.pdf”

‘ Domain user id and pwd
Dim networkCredential As New networkCredential(“username”,”password”,”domain”)

myWebClient.Credentials = networkCredential

‘ File saves in a byte array after downloading
Dim FileBuffer As Byte() = myWebClient.DownloadData(remoteFilePath)


‘ Clearing the header content and headers
Response.ClearContent()
Response.ClearHeaders()


‘ The following makes a file to be a pdf one
Response.ContentType = “application/pdf”

‘The following makes the file downloadable, a dialouge will open which ask the user to save it
Response.AddHeader(“Content-Disposition”, “attachment;filename=Billing.Pdf”)

‘This writes the whole file into the browser
Response.BinaryWrite(FileBuffer)
Response.Flush()
Response.Close()
