Passing a ref to overriden constructor 1

[MinnisotaFreezing]

Can anyone help me with this? I have in my declare:

CheckBookSet  & m_CBSet;
AddItemDlg(CWnd* pParent = NULL);   

AddItemDlg(CWnd* pParent, CheckBookSet & CBSet, int line);

then the constructor:

AddItemDlg(CWnd* pParent, CheckBookSet & CBSet, int line);
{
m_CBSet = CBSet;
}

I get double errors, "I must ini reference in consructor" and also m_CBSet = CBSet "= operator is not available.

Can anyone help me out? I can make it work by passing CheckBookSet as a pointer to my overriden constructor, but I would like to pass by ref. Is this possible? Smart?

Thanks in advance for any help you can give me.

The first error may be because of the fact that u r not initializing the reference variable in the first constructor.

I am not sure about the second error, but i think u will have to operator=() for the CheckBookSet class/struct.

Yes, when you have member variable declared as a reference it must be initialized in all constructors. And 2nd problem : you cannot initialized reference in the constructor body.
Example: Do it this way

class Test
{
public:
	Test( int& i )
	: m_i( i )
	{}

private:
	int& m_i;
};

not this way...

class Test
{
public:
	Test( int& i )
	{
		m_i = i;
	}

private:
	int& m_i;
};
