Hello Experts,
I am trying to display a PDF file in my ASP.net page based on the binary data received from the ASP.net Web service. Below is the code. though I am getting the data from the Web Service for some reason, if I run the below mentioned code on page load I am getting the above mentioned error.
Please help
Response.Buffer = True
Response.ContentType = "application/pdf"
Response.AddHeader("Content-Disposition", "Inline")
Dim ws As New imageGenService.Service1
Dim imagebyte As Byte() = Nothing
imagebyte = ws.generateSamplePDF()
If imagebyte IsNot Nothing Then
'"attachment; filename=Whatever.pdf"
Dim MemStream As New System.IO.MemoryStream
Dim doc As New iTextSharp.text.Document
Dim reader As iTextSharp.text.pdf.PdfReader
Dim numberOfPages As Integer
Dim currentPageNumber As Integer
Dim writer As iTextSharp.text.pdf.PdfWriter = iTextSharp.text.pdf.PdfWriter.GetInstance(doc, MemStream)
doc.Open()
Dim cb As iTextSharp.text.pdf.PdfContentByte = writer.DirectContent
Dim page As iTextSharp.text.pdf.PdfImportedPage
Dim rotation As Integer
reader = New iTextSharp.text.pdf.PdfReader(imagebyte)
numberOfPages = reader.NumberOfPages
currentPageNumber = 0
Do While (currentPageNumber < numberOfPages)
currentPageNumber += 1
doc.SetPageSize(PageSize.LETTER)
doc.NewPage()
page = writer.GetImportedPage(reader, currentPageNumber)
rotation = reader.GetPageRotation(currentPageNumber)
If (rotation = 90) Or (rotation = 270) Then
cb.AddTemplate(page, 0, -1.0F, 1.0F, 0, 0, reader.GetPageSizeWithRotation(currentPageNumber).Height)
Else
cb.AddTemplate(page, 1.0F, 0, 0, 1.0F, 0, 0)
End If
Loop
If MemStream Is Nothing Then
Response.Write("No Data is available for output")
Else
Response.BinaryWrite(MemStream.GetBuffer())
End If
End If
