Byte[] buffer = client.Download Data(path);

if (buffer != null)

Response.Conten tType = "applicatio n/pdf";
Response.AddHea der("content-length", buffer.Length.T oString());
Response.Binary Write(buffer);

Hi,

If it is ASP .Net just add response.redire ct("The PDF file path") in the code

what if I am storing the pdf in a blob column in oracle? how do I assign the binary value to the response function?

I did not see anyone actually answering this question.

I thought if I provide my current solution, I might get some constructive feedback and perhaps some assistance.

While the following ASP.NET 2.0 (2005 SP1) w/ VB.NET 2005 SP1 solution does provide a PDF rendering of the oracle stored blob PDF file, I'd like to display the PDF reader within my current page template - In Classic ASP I would do this by utilizing a report reader object.

How do I do this in ASP.NET 2.0?

If you have a sample from that language would work for me too as I can and do read, understand and develop in C#. (I do not currently have any paying customers who develop in C#, but I do use it.)

Very very useful...
Thank you very much...

Just translating & refining the code for C# users,

all credit is yours...!

Code:

            StreamReader streamReader = new StreamReader(PDFDirectoryPath);

            Stream stream = streamReader.BaseStream;

            BinaryReader binaryReader = new BinaryReader(stream);

            byte[] sendbyteArray = binaryReader.ReadBytes(Convert.ToInt32( binaryReader.BaseStream.Length));

            Response.ContentType = "application/pdf";
            Response.AddHeader("Content-Type", "application/pdf");
            Response.AddHeader("Content-Disposition", "inline");
            Response.BinaryWrite(sendbyteArray);
            Response.End();
