#include <msclr\auto_handle.h>

using namespace System;
using namespace msclr;

ref class ClassA {
   String^ m_s;
public:
   ClassA( String^ s ) : m_s( s ) {
      Console::WriteLine( "ClassA constructor: " + m_s );
   }
   ~ClassA() {
      Console::WriteLine( "ClassA destructor: " + m_s );
   }

   void PrintHello() {
      Console::WriteLine( "Hello from {0} A!", m_s );   
   }
};

int main()
{
   ClassA^ a;

   // create a new scope:
   {
      auto_handle<ClassA> agc1 = gcnew ClassA( "first" );
      auto_handle<ClassA> agc2 = gcnew ClassA( "second" );
      a = agc1.release();
   }
   // agc1 and agc2 go out of scope here

   a->PrintHello();

   Console::WriteLine( "done" );
}

ClassA constructor: first
ClassA constructor: second
ClassA destructor: second
Hello from first A!
done
