PDF Programming
PDF and Active Server Pages
Active Server Pages are objects that write a specific file formats (MIME) to the web page. Whether it’s FDF or PDF, you must specify a Content Type or MIME type for the ASP to write to.
FDF Content Type is as follows:
Response.ContentType = “application/vnd.fdf”
PDF Content Type is as follows:
Response.ContentType = “application/pdf”
Since we are writing the PDF Format we use the PDF MIME for this example.
We also need a component registered with the Reg32Srv.dll (Server) called BinReadWriteBuf.dll. This object can read a binary file (PDF) and return it into a variable in an Active Server Pages Document.
<%@ Language=VBSCRIPT %>
<% Option Explicit %>

‘ Declare Binary Object Variables
Dim vntStream3, binObj3
‘ Turn Buffer On (Must be enabled in Server Settings)
Response.Buffer = true
‘ Declare PDF Filename Variable
Dim strPdfFileName
strPdfFileName = Server.MapPath(“/PDFs/My_PDF.pdf”)
‘ Create Binary Read Buffer Object
Set binObj3 = Server.CreateObject("binReadWriteBuf.BinRead")
‘ Set the Response MIME or Content Type = PDF
Response.ContentType = "application/pdf"
‘ Load Binary File to Object Variable
vntStream3 = binObj3.readBinFile(cPdfFileName)
‘ Write the Variable to Buffer
Response.BinaryWrite vntStream3
‘ Close Object
Set binObj3 = Nothing
‘ Clear errors
err.Clear
‘ End Response
Response.End
