如何在自定义类中获得view指针

[yofly]

小弟想在自定义类中 让button在view中create
因此就要用到view指针
可是用CMainFrame * m_pf = (CMainFrame *)AfxGetMainWnd();
CyouView *m_view = (CyouView *)m_pf->GetActiveView();

include view。h 和frame。h后 却有更多报错了

请问应该 怎样 获得这个 指针呢？/ 谢谢

报的什么错，楼主帖出来看看。获得指针实现起来没有问题，主要看是在什么位置。

我知道了，
#include "SnakeEatingDoc.h" 放到snakeeatingview.h的头文件中

CSnakeEatingDoc
没包含的定义。。。
