EmergenceDoc.obj：错误LNK2019：解析外部符号

我正在创建在VS2010一个简单的MFC的文本编辑器，以便学习C++和我已经打了一个比特的绊脚石的....EmergenceDoc.obj：错误LNK2019：解析外部符号

具体地说，我碰到下面的错误在我的生成日志：

让编译器转储预处理的文件，并在编译'CEmergenceCntrItem'的c'tor时看看'REOBJECT'的计算结果。您可以通过指定编译器开关[/ P（预处理到文件）]（http://msdn.microsoft.com/zh-cn/library/8z9z0bx6.aspx）指示MSC输出预处理文件。 ALL UPPERCASE通常表示一个预处理器宏 - 它可能不是它的样子。 - 第二个想法：.cpp文件中的#pragma once看起来不正确。在你的头部缺乏守卫看起来不正确。 – IInspectable

CEmergenceCntrItem（REOBJECT * preo = 0，CEmergenceDoc * pContainer = 0）; – pintee

所以我猜测REOBJECT evauluates为0，但我不知道这是什么意思..... – pintee

只需将cntritem.cpp和cntritem.h复制到资源文件夹！
