Encrypt Mail Attachments

(0) ShareShare

Posted on by sylvesterPowerBi 384

Dears Experts,

i am trying to send an encrypted PDF File using PdfSharp.

so far i managed to send the pdf file to my email. but i want to send it as a secured Pdf file with a password that i insert in my code.

the email is being sent from my x++ code using the  SysMailerMessageBuilder and i am using the PdfSharp classes for the security settings.

my problem is once i want to attach my Pdfsharp.pdfdocument into SysMailerMessageBuilder.addAttachement( Pdfsharp.pdfdocument) , the type is not supported since mailer messager supports  System.IO.MemoryStream,

Kindly advise what to do in order to send the Attached email as encrypted file.

Regards,

I have the same question (0)

    You must respect types of parameters - if a method expects an apple, you can't give it a trolleybus. In your case, you need to save the document to either a stream or a file.

    Try something this:

    using (MemoryStream stream = new MemoryStream())
{ 
    pdfDocument.Save(stream, true);
    // Plus may need to reset the position
    stream.Position = 0;
}

    i am already using stream, is it possible to rewrite to above code to this below?

    System.IO.MemoryStream stream = new System.IO.MemoryStream(reportBytes);

                
                   stream.Position = 0;

                   str fileContentType = System.Web.MimeMapping::GetMimeMapping(fileName);

                   _stream = stream;

                   pdfPages = Document.get_Pages();

                   Document.Save(_stream, true)
                   ...
                   ...
                    mailer.addAttachment(_stream, strFmt('%1%2','AAA', '.PDF'));

    Why do you write the data to the Stream you created from reportBytes? You ignore the data from reportBytes, thereofore it's likely a bug.

    By the way, you populate fileContentType but then you ignore it.

    You probably want something like this:

    str fileContentType = System.Web.MimeMapping::GetMimeMapping(fileName);

using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
{
	document.Save(stream, true);
	stream.Position = 0;
	mailer.addAttachment(_stream, fileName, fileContentType);
}

    i faced an error saying : "Cannot save a PDF document with no pages." while saving the document

    this error occurs when the number of pages in the pdf document is null !

     i tried to add this :pdfpages =  PdfDocument.get_Pages();

    with no luck !

    Hi sylvesterPowerBi,

    Do you have any content in your PDF file? 

    Try 

    PdfPage page = new PdfPage();
document.AddPage(page);

    Hi Will after using your code, i am now able to save the document, but i faced this error  Cannot access a closed Stream on mail.addattachment() method below

    any idea why ? here's my code

                    mailer.setSubject(SysEmailMessageSystemTable.Subject " " mthName(mthOfYr(PayrollPayStatement.PaymentDate)));
                mailer.setFrom(SysEmailParameters::find().SMTPUserName);
                mailer.setBody(SysEmailMessageSystemTable.Mail " " mthName(mthOfYr(PayrollPayStatement.PaymentDate)));
                mailer.addTo(Email);
                 fileContentType = System.Web.MimeMapping::GetMimeMapping(fileName);
                using (System.IO.MemoryStream stream = new System.IO.MemoryStream())
                {
                    Document.AddPage(pdfPages);
                    Document.Save(stream, true);
                    // Plus may need to reset the position
                    stream.Position = 0;

                    mailer.addAttachment(stream,fileName,fileContentType);
                }

    You'll need Document.Save(stream, false); in this case.

    By the way, can you please remove the unnecessary spaces from your code next time (e.g. the extra 16 spaces at line 2 before mailer)?

  • sylvesterPowerBi Profile Picture

    Using the below code i am now able to send the file but it's not coming incrypted

    PdfSharp.Pdf.IO.PdfPasswordProvider pass;
stream = new System.IO.MemoryStream();
stream.Write(reportBytes,0,reportBytes.Length);
fileContentType = System.Web.MimeMapping::GetMimeMapping(fileName);
stream.Position = 0;
Document =PdfSharp.Pdf.IO.PdfReader::Open(stream,password,PdfSharp.Pdf.IO.PdfDocumentOpenMode::Import,pass);
Document.AddPage(pdfPages);
Document.Save(stream);
mailer.addAttachment(stream,fileName,fileContentType);

    is there anything missed ?

    You add reportBytes to the stream and then you're trying to overwrite it with something else on Save(). It's strange and easily dangerous. For example, you write 1000 bytes and then you overwrite first 800 bytes. The result won't make any sense.

    Use two streams - one for the input and one for the output.

    Also, don't forget to close the streams. That's the point of 'using' blocks in my code.
