This is most likely down to my lack of experience with Ruby but I am  
struggling to obtain the microsoft windows HWND relating to a VRForm  
object when using VRuby.

The class hierarchy  
[404 Page Not Found. - GMOインターネット](http://www.osk.3web.ne.jp/~nyasu/vruby/referer/vr/VRForm.html) indicates  
that VRForm inherits from SWin::Window which has the property hWnd.

However, attempting to refer to this property using the following;

puts MyForm.hWnd

gives the error;

undefined method `hWnd’ for MyForm:Class (NoMethodError)

If I create an SWin::Window I can successfully refer to the hWnd  
property.

Since VRForm derives SWin::Window why can’t I refer to that property?
