Hi!

Here's an example from the iSED-knowledgebase.
I'll insert the complete knowledgebase with Michel here soon.

Best regards,

Knowledge Base

Streaming the PDF document directly to the browser in ASP

The SaveToVariant function returns a byte array which can be sent directly to the browser. This method means that you do not need to create a physical file for your users to download, the file can be sent directly to the user's browser.

Setup iSEDQuickPDF according to the previous tutorial.

Now write an ASP script to generate your PDF document, and stream it to the browser:

<%
Dim QP
Set QP = Server.CreateObject("iSED.QuickPDF")
Call QP.UnlockKey("type your license key here")
Call QP.DrawText(100, 500, "ASP stream to browser test")
Call QP.CompressContent()
Response.ContentType = "application/pdf"
Response.AddHeader "Content-disposition", _
"attachment; filename=test.pdf"
Response.BinaryWrite QP.SaveToVariant()
Response.End
Set QP = Nothing
%>

The following line compresses the PDF document, this results in a faster download of the document. The CompressContent function should obviously be called before the SaveToVariant function.

Call QP.CompressContent()

Now the HTTP headers are set up to tell the browser that the information is a PDF document:

Response.ContentType = "application/pdf"
Response.AddHeader "Content-disposition", _
"attachment; filename=test.pdf"

Finally, the binary PDF data is generated using the SaveToVariant function, and the resulting byte stream is sent to the browser.

Response.BinaryWrite QP.SaveToVariant()
Response.End
