如何在子对话框中获取视图窗口指针，以供发送消息？？？

Question

???->SendMessage(WM_USER_DIALOG_DESTROYED, 0, 0);

Answer 1

CFrameWnd::GetActiveView 先获取主框架的指针

Answer 2

其他类中获取当前活动视图CxxxView指针:多文档:
CMainFrame *pMF=(CMainFrame *)AfxGetMainWnd();
CChildFrame *pCF=(CChildFrame *)pMF->GetActiveFrame();
CxxxView *pActiveView = (CxxxView *)pCF->GetActiveView();
单文档:
#include "MainFrame.h"
#include "xxxDoc.h"
#include "xxxView.h"
CMainFrame *pMF=(CMainFrame *)AfxGetMainWnd();
CxxxView *pActiveView = (CxxxView *) pMF->GetActiveView();
