PDFsharp & MigraDoc Foundation

I'm trying to compile PDFSharp as a COM Visible assembly so I can use the assembly in C++. I get the following error about Ambiguous Names when the compiler is trying to create the type lib:

c:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(3019,9): error MSB3212: The assembly "C:\Documents and Settings\jccapps\Desktop\PDF\PDFSharp-MigraDocFoundation-1_31\PDFsharp\code\PdfSharp\bin\Debug\PdfSharp.dll" could not be converted to a type library. Type library exporter encountered an error while processing 'PdfSharp.Pdf.Content.Objects.OpCodeName.B, PdfSharp'. Error: Ambiguous name

Does anybody know a way around this problem?

Thanks

I might have an anwser to my own question. There is a file called OpCodeName.cs. Inside of this file is an enum that has several different values in it that conflict case wise (i.e. B and b). I changed the enum to where the names of each value is unique based on name instead of on case. So now instead of having "B" and "b", I have "upB" and "b". There where several others like this in the enum. Once I got this changed there were several more errors where I had to go fix the names in the Operators.cs file, but the compiler caught all of these and they were really simple to find and fix.

It all compiles. Now it is time to see if it will work.

Has anybody out there used PdfSharp in the context of native c++?

I was able to cocreate an instance of _PdfDocument in my c++ class, but intellisence and the com\ole viewer do show any methods associted with _PdfDocument. Hmm... I tired to create an instance of PdfDocument but returned an error saying that "myvariable uses undefined struct 'PdfSharp::PdfDocument'.

Can PdfSharp even be used from native c++?

That's not my area of expertise.
I wouldn't try that and use a different approach.

I'd create an assembly using managed code (C# or C++) to create the documents.
I'd call this assembly from COM, giving it an interface as small as possible.

In the best case you'll need one COM call only to create a complete document.
You can pass all required data in a single CSV or XML string, or use a user-defined structure.
Or create the document using MDDDL in C++ and pass that to the managed code.
