I have a Crystal Report that I'm trying to export as a stream as a PDF. I'm able to view it in the Crystal Report Viewer in the browser, but when I open the PDF in a new tab in Chrome, I get an error stating it failed to load the PDF. Whenever I run it on my server, I get the error, but I do not get the error running locally. Do you know what could cause this?

        Dim expStream As Stream = CurReport.ExportToStream(expFormatType)
        expStream.Seek(0, SeekOrigin.Begin)
        Dim abyBuffer As Byte() = New Byte(expStream.Length - 1) {}
        expStream.Read(abyBuffer, 0, expStream.Length)
        expStream.Dispose()
        expStream = Nothing

        Response.Buffer = True
        Response.Clear()
        Response.ContentType = "application/pdf"
        Response.AddHeader("content-disposition", "inline; filename=" & rptFile)
        Response.AddHeader("content-length", abyBuffer.Length.ToString())
        Response.OutputStream.Write(abyBuffer, 0, abyBuffer.Length) ' Send to client
        Response.Flush() ' Finalize

        HttpContext.Current.ApplicationInstance.CompleteRequest()

  • Compare the responses between dev & live via your browser dev tools. Have the browser save it to a file instead of opening it, then open it with a text editor, and check for anything that shouldn't be in there, like error messages. Commented Sep 23 at 13:21
