NULL pointer in C++ .NET

I cant use the NULL constant to check a pointer (eg. say Object*) whether it
is valid or not - when I use C++ .NET.
What comes in place of NULL in the managed extension of C++
Pls Help.

Sincerely

The Managed C++ contant for null is NULL. It's a while since I've done any
Managed C++ (thankfully) so I can't remember if there's a header or project
setting you might have mis-tweaked.
