问题
I'm creating an application that will heavily use PDF file viewing. Is there a difference/advantage in using WindowsFormsHost over WebBrowser? WebBrowser is just a line of code versus WindowsFormsHost setup. So, I'm curious if there are any advantages of using WindowsFormsHost?
回答1:
WPF WebBrowser control runs in IE protected mode by default, and Adobe PDF Reader plugin is known to have issues with that. Check this question. I'd go with WindowsFormsHost and host PDF Reader ActiveX directly, here's how.
