问一个问题，关于动态创建CView类

[alixnuaa]

我利用MFC创建了一个基于SDI的文档，是explore样子的，左边是CTreeView的类，右边是CListView的类，然后建立了一个基于CListView的类，希望通过左边的树形结构，动态的在右边响应，程序老是出现运行时的错误，请问应该怎么操作的？
有没有具体的例子可以参考的？
CView类创建的时候需要有一个ID 号，可是动态生成的时候没有找到具体的 ID号，请各位高手指教。

CView类创建的时候需要有一个ID 号?
有这个需要吗？

是因为我想在左边点树的时候，右边会有不同的响应，所以就想多创建几个CView的类，然后用到new和Create的时候，需要了ID 号的

[alixnuaa]

那怎么和左侧的树联系在一起啊？
