Adobe PDF not showing on IIS7

Question

I got this code below working on local (using source code) perfectly fine. But when I published it on IIS7 the PDF is not showing anymore.

Answer 1

When you say "not showing" I am assuming you want the PDF to be opened on the client, not the server. Normally you would send the file to the browser. Process.Start() will start a process server-side, so even if the AppPool is allowed to start a process, it will only open the pdf on the server. Below is how you send a file from the server to the client.

string strPath = Server.MapPath("~/reports/GeneratedReport.pdf");

//read the file from disk and convert to a byte array
byte[] bin = File.ReadAllBytes(strPath);

//clear the buffer stream
Response.ClearHeaders();
Response.Clear();
Response.Buffer = true;

//set the correct contenttype
Response.ContentType = "application/pdf";

//set the correct length of the data being send
Response.AddHeader("content-length", bin.Length.ToString());

//set the filename for the file
Response.AddHeader("content-disposition", "attachment; filename=\"GeneratedReport.pdf\"");

//send the byte array to the browser
Response.OutputStream.Write(bin, 0, bin.Length);

//cleanup
Response.Flush();
HttpContext.Current.ApplicationInstance.CompleteRequest();

VB

Dim strPath As String = Server.MapPath("~/reports/GeneratedReport.pdf")

'read the file from disk and convert to a byte array
Dim bin() As Byte = File.ReadAllBytes(strPath)

'clear the buffer stream
Response.ClearHeaders
Response.Clear
Response.Buffer = true

'set the correct contenttype
Response.ContentType = "application/pdf"

'set the correct length of the data being send
Response.AddHeader("content-length", bin.Length.ToString)

'set the filename for the file
Response.AddHeader("content-disposition", "attachment; filename=""GeneratedReport.pdf"""")", send the byte array to the browser, Response.OutputStream.Write(bin, 0, bin.Length))

'cleanup
Response.Flush
HttpContext.Current.ApplicationInstance.CompleteRequest
