I have a simple question but I can't find it on any newsgroups.

I have a MC++ class that contains a private field of native type
   private:
      HTTP_RESPONSE _httpResponse.

I need to get it's address
   HTTP_RESPONSE* pResponse = &(this->_httpResponse);

But I get this build error
       error C2440: 'initializing' : cannot convert from 'HTTP_RESPONSE
__gc *' to 'HTTP_RESPONSE *'

Can I store this structure as a member of my class and then work with it as
an unmanaged type?
