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.
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.
