<html><body>
This demo shows how to embed an ActiveX control in a wxPython application, (Win32 only.)
<p>
The MakeActiveXClass function dynamically builds a new Class on the fly, that has the
same signature and semantics as wxWindow. This means that when you call the function
you get back a new class that you can use just like wxWindow, (set the size and position,
use in a sizer, etc.) except its contents will be the COM control.
<p>
This demo embeds the Adobe Acrobat Reader, and gives you some buttons for opening a PDF
file, changing pages, etc. that show how to call methods on the COM object. If you don't
have Acrobat Reader 4.0 installed it won't work.
