MFC中如何在对话框类的按钮处理函数中获得文档类指针

回答1：

首先从对话框的按钮处理函数中获得MainFrame指针
CMainFrame *pMain=(CmaimFrame *)AfxGetApp()->m_pMainWnd;
然后获得相应视图指针CYourView *pView=(CyourView *)pMain->GetActiveView();
最后获得视图对应的当前文档指针 CDocument * pCurrentDoc =(CFrameWnd *)m_pMainWnd->GetActiveDocument();

以上需要注意在对话框类中包含MainFrm.h和相应的视图类的头文件
