Is the PDF attachment code buggy?

[mattewan]

Hello,

I'm using the following code to generate a PDF with text & embed files:

Code: Select all

        private void WriteEmail(sEmail email, string filename) {

            GdPicture14.GdPicturePDF oPDF = new GdPicture14.GdPicturePDF();
            oPDF.CreateFromText(GdPicture14.PdfConformance.PDF1_4, 595, 842, 30, 30, 30, 30, GdPicture14.TextAlignment.TextAlignmentNear, email.emailContent, 12, "Calibri", false, false, false, false);

            string orgFilename;
            string newFilename;
            for (int i = 0; i < email.Attachments.Count; i++)
            {
                if (oPDF.EmbedFile(email.Attachments[i].newFilename, "") != GdPicture14.GdPictureStatus.OK)
                {
                    Console.WriteLine("ERROR INSERTING ATTACHMENT");
                }
            }
            oPDF.SaveToFile(filename);
        }
        

The above code works and I get a PDF, A4 in size with a dynamic amount of pages, depending on how much content there is to insert. However, I am having an issue where certain PDF's, which may have 4 attachments for example, will let me open 3 of them and one of them wont open. If I open this pdf in Acrobat Pro, I can delete the 3 attachments that are viewable, but I can't delete the file that it wont let you open or view. It's like acrobat can't locate the file in the PDF.

I have seen this happen to jpegs, gif files, html documents, etc.

What could be causing this? I can't share the files that are causing the issue because of data protection. I can confirm that if I add the same attachments using acrobat pro, it is able to view and delete them.

Am I creating the pdf incorrectly? Either that, or maybe there is a bug in the pdpicture attachment code? This is happening to about 1 in 50 PDF's I'm creating.

I have tried a few versions of GDPicture 14, including the latest as of today.

Cheers,

Matt

Hi mattewan.

Can you transmit the filenames of the attachments when the problem occurs.
Perhaps you can try

if (oPDF.EmbedFile(email.Attachments.newFilename + i.ToString(), "")

Hope this help
Best regards.

Thanks for replying.

I have an email with the following two attachments:

TEXT.htm
image001.jpg

In this example, TEXT.htm won't open (nothing happens when i click the attachment in acrobat, and it wont let me delete it either). If I insert just image001.jpg or TEXT.htm on their own, both work, but don't work when stored together.

I have tried adding a counter to the end of the filename to see if that helps, same issue:

TEXT.htm 1
image001.jpg 2

The jpeg will load, TEXT.htm wont.

Kind regards,

Matt

Hi mattewan

Without the final PDF, it will be difficult to find what is the problem.
Can you make a test storing them according the alphabetical order, please.
image001.jpg first and then Text.htm

Best regards.
