我没有定义它, MSDN中也找不到它!
4 个解决方案
#1
应该是一些函数需要的参数！
#2
搜一下源代码，发现CDialog和CPropertySheet类里有这个member(VC7的mfc）。
#3
TO CDialog
how does the constructor set the parent? When you pass a parent window pointer to CDialog::CDialog, it stores the pointer in a member m_pParentWnd, which it uses later in DoModal. So you need to manually set m_pParentWnd after creating the object, but before running the dialog. But you can't do that either because CDialog::m_pParentWnd is protected! Sigh.

正应该是在CDIALOG中的! 但是CDIALOG中的构造涵数有一个参数, CWnd* pParent = NULL,
这不是重复了吗?
