operator=

[Amon Ra]

i have this class:

class SubclassedObject    {
public:
    MessageAnswer MsgResponse; //

    SubclassedObject operator= (SubclassedObject);

    LRESULT CALLBACK SubclassWndProc(HWND hwnd, UINT Message, WPARAM wParam, 
                                                                 LPARAM lParam);
}; 

i have tried this as the operator=

SubclassedObject SubclassedObject::operator = (SubclassedObject sobj)
{
    this->MsgResponse = sobj.MsgResponse;
    this->SubclassWndProc  = sobj.SubclassWndProc;
        return this;
} 

but it gives me errors such as there

c:\my documents\subclasspractice\easysubclass.h(46) : error C2659: '=' : overloaded function as left operand
c:\my documents\subclasspractice\easysubclass.h(47) : error C2664: '__thiscall SubclassedObject::SubclassedObject(const class SubclassedObject &)' : cannot convert parameter 1 from 'class SubclassedObject *const ' to 'const class SubclassedObject &'
        Reason: cannot convert from 'class SubclassedObject *const ' to 'const class SubclassedObject'
        No constructor could take the source type, or constructor overload resolution was ambiguous
c:\my documents\subclasspractice\easysubclass.h(47) : error C2553: no legal conversion of return value to return type 'class SubclassedObject *'

can anyone help me? thanks
