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

今天在利用MFC時，把控件類的對象：CEdit對象作為參數傳遞給函數，結果出現在了'CObject::CObject' : cannot access private member declared in class 'CObject'的錯誤，在網上搜了下發現在了下面這段話：

• 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，從CObject類繼承的類是不能被復制，因為他的復制構造函數被聲明為私有的，所以不能采用 void Fun(CEdit edit)這種傳參方法，因為這種傳參也需要復制CEdit對象，后來改為void Fun(CEdit & edit)，將參數作為引用傳遞給函數就不會出錯了，希望大家遇到同樣問題時可以注意一下。
