Hi guys,

i have a pdf file thats gets created by an activex control.
it is then saved to the local machine c:\temp.pdf.

how would i display this in an iframe for user to view.
i have tried this, but when i run the web page it foes not find the file.

Dim buffer As [Byte]() = client.DownloadData("c:\temp.pdf")
Response.ClearContent()
Response.ContentType = "application/pdf"
Response.AddHeader("content-length", buffer.Length.ToString())
Response.BinaryWrite(buffer)
Response.Flush()
Response.End()

any ideas?

thanks

Hi,

i tried this but it requires me to copy to a folder on server first.

Response.Clear()
Response.ClearContent()
Response.ClearHeaders()
Response.ContentType = "application/pdf"
Dim FilePath As String = Server.MapPath("~/temp/temp.pdf")
Me.lblerror.Text = FilePath
Response.WriteFile(FilePath)
Response.Flush()
Response.End()

it works,
will use this until i can get the above to work.

thanks

When you say 'local machine' I assume you mean the 'client side'.
If this is the case you can try using "file:///C:/temp.pdf" in the iframe src. It will depend on the browser/plugin/settings if this will work or not, since the file:/// prefix tends to throw security warnings for some people.

You can quickly read up on it here: http://en.wikipedia.org/wiki/File_URI_scheme[^]

If this does not help in your situation, it might be best to generate the pdf server side and then show it in the iframe using a normal http(s) url.

Hope this helps.
