void CEx_SDIView::OnLButtonDblClk(UINT nFlags, CPoint point)
{
    // TODO: Add your message handler code here and/or call default
    CMainFrame * pFrame=(CMainFrame*)AfxGetApp()->m_pMainWnd;
    CStatusBar * pStatus=&pFrame->m_wndStatusBar;
    CString str;
    if(pFrame->m_bIsTest)
   
        str.Format("你在(%d,%d)处双击鼠标",point.x,point.y);
    else
        str.Empty();
    if (pStatus)
        pStatus->SetPaneText(1,str);
    CView::OnLButtonDblClk(nFlags, point);
}
最后运行时出现这样的错误：
F:\ghethe\Ex_SDI\Ex_SDIView.cpp(108) : error C2065: 'CMainFrame' : undeclared identifier
F:\ghethe\Ex_SDI\Ex_SDIView.cpp(108) : error C2065: 'pFrame' : undeclared identifier

帮忙解决一下吧

你要把cwnd*转化为CMainFrame* ，CMainFrame在MainFrm.h中定义，你肯定要
#include "MainFrm.h".
