"OpenFileDialog" class seems to be *sealed*, so You cannot
inherit from it...

Look at abstract "FileDialog" class in .NET docs.

"FileDialog" is an abstract class which means that is contains one or
more abstract methods/properties. So, you've go to impements
those abstract members ("RunFileDialog(...)")

....But it looks that Microsoft does not include that method's
description in docs. There's no info about "NativeMethods"
class/structure??

I'm sorry but it looks that i drive You in the dead-end.
I was hoping that "FileDialog" was designed to extends its
functionality... but i was wrong. It looks like internal-sealed
class. :(

PS: If anybody has any practise with inheriting FileDialog,
don't be afraid of post.
