41 # The ActiveX module from Acrobat 7.0 has changed and it seems to now
42 # require much more from the container than what our wx.activex module
43 # provides. If we try to use it via wx.activex then Acrobat crashes.
44 # So instead we will use Internet Explorer (via the win32com modules
45 # so we can use better dynamic dispatch) and embed the Acrobat control
46 # within that. Acrobat provides the IAcroAXDocShim COM class that is
47 # accessible via the IE window's Document property after a PDF file
48 # has been loaded.
49 #
50 # Details of the Acrobat reader methods can be found in
51 # http://partners.adobe.com/public/developer/en/acrobat/sdk/pdf/iac/IACOverview.pdf
