PDFsharp & MigraDoc Foundation

Hi all,

Ive been writing a vb.net plugin that processes two xml files and outputs two pdfs along with two updated xmls. Everything works well until I save the second generated pdf to a memorystream in order to convert it to base64 to insert into the second updated xml.

The error raised is: "The dictionary already has a stream."

BTW: The first pdf is pdfSharp only, the second is a MigraDoc document.

Has anyone seen this error before? Any ideas on a way around?

TIA.

I am getting the same error - Anyone have any idea how to resolve this

Resolved this - Caused by not creating a new occurrence of the class for each document

Adria,

I know this was a long time ago but do you remember what class you need to create a new isntance of?

I'd like to create a Migradoc, add pages and then do two steps:
1) save it to a memory stream (for embedding in to another file)
2) save it to a file.

I get the dictionary error if I use the same pdf object for both. I'd like to do this to save cpu cycles in creating two identical documents!

Performance will be better if step 2 uses the memory stream created in step 1 to create the file.

Thanks Thomas.

I probably over simplified my problem. In between step 1 and 2 I want to add a watermark to the report. In the end I figured I could save v1 to a memory stream. Use pdfReader to re-load the doc from the same memory stream, then add the watermark and do the save v2 (to a file).

BTW for anyone looking the vb.net code to save the memory stream to a file is:
