Q:
What I'm looking for is a way to access the document properties. In
particular, I would like to modify the initial view and hide the menu
bar and tool bar.
A:
Using the latest version of PDFNet SDK (v.3.2) you can use
PDFDocViewingPrefs class to modify the initial view and hide the menu
bar and tool bar.
For example
PDFDocViewPrefs pref = doc.GetViewPrefs();
pref.SetPref(PDFDocViewPrefs.ViewerPref.e_HideToolbar);
...
doc.Save(...);
