关于'CObject::CObject' : cannot access private member declared in class 'CObject'

今天在利用MFC时，把控件类的对象：CEdit对象作为参数传递给函数，结果出现在了'CObject::CObject' : cannot access private member declared in class 'CObject'的错误，在网上搜了下发现在了下面这段话：

• CObject cannot be copied - its copy constructor is declared private. Thus, any class derived from CObject cannot be copied either, unless it does something very special (explicitly defines a public copy constructor that bypasses one in its base class). CStatic et al are derived from CObject and don't define a copy constructor: thus they, too, are non-copyable.

  大概意思是，从CObject类继承的类是不能被复制，因为他的复制构造函数被声明为私有的，所以不能采用 void Fun(CEdit edit)这种传参方法，因为这种传参也需要复制CEdit对象，后来改为void Fun(CEdit & edit)，将参数作为引用传递给函数就不会出错了，希望大家遇到同样问题时可以注意一下。
