PDFsharp & MigraDoc Foundation

Hi I am using PDFSharp v1.31 to create PDFs based on user input. This work well. Later in the process I need to open this PDF and add a Case Number. When I try to save the PDF after writing the case number I get the message: 'The document cannot be modified.'
Is it possible to alter a PDFSharp created docuemnt once it has been saved originally?

Thanks

Hi!

Do you open the document with the Modify flag?

Sorry for the delay i've been out of touch for several days.
Ashamed to say I did not try opening with Modify flag. Will give it a try.

Thanks

Opening with Modify flag does allow mw to edit the document. However, I now receive the message:
'Object type transformation must not be done with direct objects.'

Ignore that message - comes in DEBUG build only.

I have been ignoring this on my development pc without an issue. However I just deployed the site to our test web server and it appears that the page is hanging up where it opens the previously created pdf and writes a case number in the pdf document. The code follows:

FinalDoc = PdfSharp.Pdf.IO.PdfReader.Open(ConfigurationManager.AppSettings("UploadTemp") & "\" & lcEFileRec.FileName, PdfSharp.Pdf.IO.PdfDocumentOpenMode.Modify)

page = FinalDoc.Pages(0)

gfx = XGraphics.FromPdfPage(page)

gfx.DrawString(lcCase.CaseNumber, fontTextBold, XBrushes.Black, New XRect(360, 115, page.Width.Point, page.Height.Point), XStringFormats.TopLeft)

FinalDoc.Save(ConfigurationManager.AppSettings("UploadTemp") & "\" & lcEFileRec.FileName)


If I comment out the line:
gfx.DrawString(lcCase.CaseNumber, fontTextBold, XBrushes.Black, New XRect(360, 115, page.Width.Point, page.Height.Point), XStringFormats.TopLeft)
it works.

Any ideas?

Use a RELEASE build of the DLLs or remove the Debug.Assert.

Thought that I was using the release build. I have many lines of code like the one causing problems on another page and it works fine. The only difference is that one creates a new docuument the other opens an existing document(the one previously created) to add something to it.

Maybe I'm confused by using the Release Build. When I build my project I have Release specifed on the compile tab of the project properties window.
