How to get the IE Window to set Landscape Printing ?

Hi everybody,

I want to set the Landscape or portrait mode of the printer with printing
over IE4 or 5. It doesnt work as in MSDN descripted.
Or do I use the wrong window?
I tryed to use the GetHwnd() from the IE4, but I always get
an exception. So I used the wnd of the following class:

 <<webbrowser2.cpp>>  <<webbrowser2.h>>
see below ...

But again no luck. How I can get the right hwnd to set the paper orientation ?

Any help is appreciated ...

Thanks

Toni
