Question

各位提提意见阿。
看看也行啊 

Answer 1

Unhandled expression .....在调用RecalcLayout时   ( diandian 回复于:2001-11-16 16:00:00)   First-chance exception in CoinDs.exe (MFC42D.DLL): 0xC0000005: Access Violation.我想问问Context和RecalcLayout的关系LRESULT CWnd::Default()
{
    // call DefWindowProc with the last message
    _AFX_THREAD_STATE* pThreadState = _afxThreadState.GetData();
    return DefWindowProc(pThreadState->m_lastSentMsg.message,
******        pThreadState->m_lastSentMsg.wParam, pThreadState->m_lastSentMsg.lParam);*****为出错后停的位置
 
 
 我在OnCreateClient外自己写个函数   ( diandian 回复于:2001-11-16 16:05:00)   void CChildFrame::ResetView()
{.........
    CCreateContext Context;
    CCreateContext *pContext;
    CPortView * pActiveView=(CPortView*)m_wndSplitter->GetPane( curRow, curCol);
    CCDDoc * pDoc=(CCDDoc *)pActiveView->GetDocument();
    if (pActiveView == NULL)
       AfxMessageBox("noview");
    Context.m_pNewViewClass= GetRuntimeClass();
    Context.m_pCurrentDoc=pDoc;//pActiveView->GetDocument();
    Context.m_pNewDocTemplate=NULL;//pDoc->GetDocTemplate();
    Context.m_pLastView=NULL;
    Context.m_pCurrentFrame=GetParentFrame();
    if (m_wndSplitter->m_hWnd)
       m_wndSplitter->DestroyWindow();
    else
    {
      for(int i=0; i<4; i++)for(int j=0; j<4; j++)
     {
       CPortView* pV = (CPortView *)m_wndSplitter->GetPane(i,j);
            pV->DestroyWindow();
     }
    }    pDoc->m_bAutoDelete=TRUE;
       delete m_wndSplitter;
       m_wndSplitter = new CMySplitterWnd;    
  
    if(!(m_wndSplitter->CreateStatic( this, 2, 2)))    
        return ;//2*2
    //init formview
    for(int i=0; i<2; i++)
      for(int j=0; j<2; j++)
      {
       m_wndSplitter->CreateView( i, j,
        RUNTIME_CLASS(CPortView),
        CSize( 145, 122)        ,//pane 的大小
        &Context    
                );}
    for( i=0; i<2; i++)for(int j=0; j<2; j++)
    {
        CPortView* pV = (CPortView *)m_wndSplitter->GetPane(i,j);
        pV->OnInitialUpdate();
    }
    for( i=0; i<2; i++)
    {
        m_wndSplitter->SetColumnInfo( i, 150, 145);
        m_wndSplitter->SetRowInfo(    i, 125, 110);
    }
    m_wndSplitter->RecalcLayout();
解释在后面（续） 
 
 解释如下   ( diandian 回复于:2001-11-16 16:10:00)   CPortView从CView继承，作为OnCreateClient的RUNTIME_CLASS(CPortView)
工程名为CoinDS  CCDoc CCDView 
程序在m_wndSplitter->RecalcLayout();停止，并出现Unhandled expression .....
进入LRESULT CWnd::Default()
{
    // call DefWindowProc with the last message
    _AFX_THREAD_STATE* pThreadState = _afxThreadState.GetData();
    return DefWindowProc(pThreadState->m_lastSentMsg.message,
******        pThreadState->m_lastSentMsg.wParam, pThreadState->m_lastSentMsg.lParam);*****为出错后停的位置
