I actually made all the object variable definitions in the header file to another class I already had in the header file and declared them static.Is there any disadvantage in moving them to the class versus declaring them as global??????

QUESTION 1)So as seen above I am creating an pointer object of type UNMANAGEDNAMESPACE.Data So i guess the larger the size of UNMANAGEDNAMESPACE.Data class, the larger the memory used will be when i define pObj = new UNMANAGEDNAMESPACE.Data().

QUESTION 2)Is there any problems in the above approach. Is there a better approach for reducing memory of the program?

public ref class ManagedCLR
{
private:
    UNMANAGEDNAMESPACE.Data *pObj; //Here my Unmanaged Class is referenced through a pointer.

public:
    ManagedCLR()
    {
        pObj = new UNMANAGEDNAMESPACE.Data(); 
    }

    ~ManagedCLR()
    {
        // clean up managed resources here

        // call the finalizer to release unmanaged resources!
        this->!ManagedCLR();
    }

    !ManagedCLR()
    {
        // clean up unmanaged resources here
        delete pObj;
        pObj = 0;
    }

    void EntryPoint(void)
    {
        //pass through to the unmanaged object
        pObj->EntryPointUnmanged(); //Here the managed program accesses my unmanaged program.
    }
};

most people are using the P/Invoke approach.

How would I provide access to these variables from the C# file?

    }

    property int s
    {
        int get()

            return UNMANAGED::s;

        void set(int value)
        {
            UNMANAGED::s = value;
        }
    }

    property int k
    {
        int get()
        {
            return UNMANAGED::k;
