Greetings,

As the subject says, I found the FAQ for "Streaming the PDF document directly to the browser" and trying to get this to work in C#/ASP. The code works but when I click on the button to generate the PDF it brings up a window to save the PDF file instead of streaming the document directly to the browser. This is what I am using.

qp.CompressContent();

Response.ContentType = "application/pdf";

Response.AddHeader("Content-Disposition", "attachment; filename=test.pdf");

Response.BinaryWrite(qp.SaveToVariant());

Response.End();

I want this to stream the PDF to the browser. If anyone could help me out I would greatly appreciate it.

Halv

I assume you are using the ActiveX version of Quick PDF Library.

According to this your approach is correct..

I have no experience with ASP.net but they are writing their data to Reponse.OutputStream ? Your code looks like it should work also.

I believe the important part is changing attachment to inline in Content-Disposition. Not sure if all the flushing and clearing is required, but this is what I have used in the past and it seems to work ok.

Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.Buffer = true;

Response.ContentType = "application/pdf";

Response.AddHeader("Content-Disposition", "inline;filename=" + fileName);
Response.AddHeader("Content-Length", fileContents.Length.ToString());
Response.Flush();
Response.BinaryWrite(fileContents);

Greetings,

Thanks samb! Your line of code got it working the way I wanted so now the PDF file shows up on the browser instead of prompting to save.
