Post subject:  Windows Service and MigraDoc Rendering
Hello,
I am developing a windows service that receives some data and creates a pdf file on the disk.
When I call the rendering function of the PdfDocumentRendered or DocumentRenderer objects the service crashes with a StackOverflow Exception. I tried to change the service's user account from local system to a domain user, and I activate the flag for desktop interation (in both configurations) with no success.
I tried to develop a console application with the same logic and in this case all works fine.
Is the problem due do the GDI+ API and windows service?

I also tried to create the hello world pdf file from the windows service with a PdfDocument and the XGraphics object, and this works.

I need to create some tables, so I think that I need Migradoc objects. So the solution that I'm following is to create a console application that creates the pdf file, and the windows service calls that application.

Do you have any solution or advice?
Thank you very much.

I suspect you'll need to supply a little more code context.

Are you saying that your call like this is having a stack overflow? myPdfDocumentRenderer.RenderDocument();
Where is the stack overflowing occurring?

The stackoverflow occurs when I call the function like this:
myPdfDocumentRenderer.RenderDocument();

Here there is the code that I use in the service:

Code:
MigraDoc.DocumentObjectModel.Document docInvoice = Invoice.CreateDocument();
docInvoice.UseCmykColor = true;

PdfDocumentRenderer pdfRenderer = new PdfDocumentRenderer(true);

// Set the MigraDoc document
pdfRenderer.Document = docInvoice;

// Create the PDF document
pdfRenderer.RenderDocument();
pdfRenderer.Save(@"Invoice.pdf")
;


When I call
Code:
pdfRenderer.RenderDocument();

occurs the stackoverflow exception.

the Invoice's CreateDocument method is this:

Code:
public MigraDoc.DocumentObjectModel.Document CreateDocument()
        {
           MigraDoc.DocumentObjectModel.Document document = new Document();
            document.Info.Author = "XXXX";
            document.Info.Title = "Invoice";

            DefineStyles();

            CreatePage();
            fillDocument();
            return document;
        }


where the other methods are the same of MigraDoc's Invoice sample.
Thank you
