多文档模板的解决

CChildFrame*   pFrame   =   new   CChildFrame();  
  CCreateContext   context;  
  context.m_pCurrentDoc=mp_doc;   //that's   the   way   I   avoid   to   create   new   document   every   time   I   open   a   new   view  
  context.m_pNewViewClass=RUNTIME_CLASS(CMulView);  
  context.m_pNewDocTemplate=pDocTemplate;  
  context.m_pLastView=(((CMainFrame   *)m_pMainWnd)->GetActiveFrame()   ?   ((CMainFrame   *)m_pMainWnd)->GetActiveFrame()->GetActiveView()   :   NULL);  
  context.m_pCurrentFrame=((CMainFrame   *)m_pMainWnd)->GetActiveFrame();  
  if   (!pFrame->LoadFrame(IDR_MULTYPE,WS_OVERLAPPEDWINDOW   |   FWS_PREFIXTITLE   ,m_pMainWnd,   &context   ))return;  
  pFrame->InitialUpdateFrame(mp_doc,TRUE);  
   
  我用了2个模板,pDocTemplate这个是第一个模板变量,我在上面已经创建了模板,用了一个菜单函数,  
  为什么我第一次打开的时候没有问题,当关闭这个窗口后,就出现错误呢?????

Here   is   my   code   to   create   multiple   view   for   current   document  
  void   CdcmviewerDoc::OnViewHistogram()  
  {  
  if(m_dataset.size()>0   &&   m_rows>0   &&   m_cols>0)  
  {  
  CMainFrame*   pframe   =   (CMainFrame*)AfxGetMainWnd();  
  pframe->CreateOrActivateFrame(((CdcmviewerApp*)AfxGetApp())->m_pHistDocTemplate,RUNTIME_CLASS(HistogramView));    
  CChildFrame*   pMDIActive   =   (CChildFrame*)pframe->MDIGetActive();  
  HistogramView   *pview   =   (HistogramView*)pMDIActive->GetActiveView();  
  pview->m_rows   =   m_rows;  
  pview->m_cols   =   m_cols;  
  pview->m_bits_stored   =   m_bits_stored;  
  pview->m_signed_image   =   m_signed_image;  
  pview->m_frame_index   =   m_frame_index;  
  CString   title;  
  title.Format(_T("Histogram:%s"),pMDIActive->GetActiveDocument()->GetTitle());  
  pMDIActive->SetTitle(title);  
  }  
  }Top

搞定，谢谢   masterz(www.fruitfruit.com)   (   )！不过用对话框当子窗口这个还是没有搞定！！！！！！Top
