在vc2010里，引用其他的项目时，如果项目里只有一般的类，就没有问题，但是如果被引用的项目里有dialog对象(或者说有CDialog的子类)的话，就不行，会报错。
这个是什么原因导致的，要如何解决呢？
部分错误信息如下：

------解决方案--------------------------------------------------------
你当前项目里是不是已经有一个和dialog相关的引用了？
从错误消息来看似乎是引用有冲突.....
------解决方案--------------------------------------------------------
引用？怎么操作的？？
mfc 程序公用，一般三种方式，#include 源代码 ，编为dll ，做成lib
------解决方案--------------------------------------------------------
你是用
<Projectname> 属性页”对话框 ->“通用属性”->“框架和引用” ？？？？
------解决方案--------------------------------------------------------
那个是针对托管程序的
