Win32: displaying PDF

I have a simple Win32 C app, which I would like to enable to display PDFs (they do not have to be files - they 开发者_JAVA技巧could be in-memory as well). I would like to control at least the zoom level and whether is should be shown as single, standalone pages or continuous "flow" of pages. I'm asking for anything else than Acrobat Reader, Poppler and Sumatra, preferably something which integrates with a dialog-based app nicely.

What about not using Sumatra itself, but mupdf, which Sumatra is built atop?
