+ @section activexcontainer_example Example
+
+ This is an example of how to use the Adobe Acrobat Reader ActiveX control to
+ read PDF files (requires Acrobat Reader 4 and up).
+ Controls like this are typically found and dumped from OLEVIEW.exe that is
+ distributed with Microsoft Visual C++.
+ This example also demonstrates how to create a backend for wxMediaCtrl.
