When I call printer.Print(); a Win32Exception "Access is Denied" error is thrown. The error occurs on PdfFilePrinter.DoSomeVeryDirtyHacksToMakeItWork() line 210.

I am going by the PdfPrint sample project included with the PDFSharp download. My code is very basic:

Code:

            PdfFilePrinter.AdobeReaderPath = adobeReaderLocation;//Path to AcroRd32.exe on windows 8 machine
            var printer = new PdfFilePrinter(_filePath, _printerName);
            try
            {
                printer.Print();
            }

Access denied means your not permitted to do this.

Try running your code with administrator privileges.

Can you be more specific? Are you referring to programmatic elevation? I am running this code in the visual studio 2012 debugger in Administrator mode.

The issue occurs during the iteration of processes. When it reaches the process "sppsvc.exe" - Microsoft Software Protection Platform Service. In taking a closer look I noticed that this little block of code is configured to swallow exceptions. I only noticed because I always run my debugger configured to stop on all CLR thrown exceptions.

So this is just a well named piece of code DoSomeVeryDirtyHacksToMakeItWork() doing some naughty things...

I'll go ahead and ignore it....

Sorry, forget the first post.

There is a try/catch around line 210 and a few exceptions will be OK.
You can tell the debugger not to break on such exceptions if they are handled in code.
