  Re: Add WaterMark In PDF Files... in use by another process

  Dec 09, 2008 04:57 AM|WeiLuDi|LINK

   Hello.

  thanks for your code...
  anyway, when i try to use it, i get this error:

  +        ex    {"The process cannot access the file 'C:\WwwRoot\Osiris.4\Portals\0\FileLezioni\105235373_Lesson_233.pdf' because it is being used by another process."}    System.Exception
  

  i've just created the pdf in this way...

                  Dim document As iTextSharp.text.Document = New iTextSharp.text.Document(rect)
                  Dim writer As iTextSharp.text.pdf.PdfWriter              
                  writer = iTextSharp.text.pdf.PdfWriter.GetInstance(document, New FileStream(path & nameFile, FileMode.Create))
                  ....
                  do my job ... then i do....

  
                  document.Close()
                  writer.Close()                
  

                  Dim watermarkImage As String = watermarkimagepath & watermarkimageName              
                  AddWatermarkImage(path & nomeFile, path & nomeFile, watermarkImage)   'callyour procedure
  

   

  is there something i forget... if the document and writer are closed... what is missing??

  thanks

  It's an error for not closing the connection properly, check again to properly close() the connection.
