Question

I am exposing this C++/CLI property to COM and COM can only accept a reference type property for complex types (it won’t accept a pointer property). What is the best way to expose a class’ private member to be used with a reference property? I tried the following (and both don’t work because I am missing a pointer to reference or vice versa conversion somewhere):

private:
    Object _myProp;
public:
property Object %MyProp { 
    virtual Object %get() 
    {
        return _myProp;
    }
    virtual void set(Object %value) 
    {
        _myProp = value;  // this line doesn't work
    }
};

And I tried this:

private:
    Object ^_myProp;
public:
property Object %MyProp { 
    virtual Object %get() 
    {
        return _myProp;   // this line doesn't work
    }
    virtual void set(Object %value) 
    {
        _myProp = %value;
    }
};

What am I doing wrong here (given that I have to use a reference property)?

Answer 1

I was trying to use “^” to return _myProp, I discovered that I should be using “*”

private:
    Object ^_myProp;
public:
property Object %MyProp { 
    virtual Object %get() 
    {
        return *_myProp;   // this line NOW works
    }
    virtual void set(Object %value) 
    {
        _myProp = %value;
    }
};
