hello.

I made MDI windows program. 

Like this :

class CChildFrame : public CMDIChildWnd

{

    CExtControlBar  m_wndSystemLog;

    CSystemLogView  m_SystemLogView;

    ....



    int CChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)

    {

         ....

         if( !m_wndSystemLog.Create( _T("System Log"), this, ID_VIEW_CHILDFRAME_BAR_0 )

         || !m_SystemLogView.Create( "SystemLog", "System Log", WS_CHILD|WS_VISIBLE, CRect( 0, 0, 10, 10 ), &m_wndSystemLog, UINT    ( IDC_STATIC ) )  )

        {

            TRACE0("Failed to create m_wndSystemLog\n");

            return -1;  // fail to create

         } 

        m_wndSystemLog.EnableDocking(CBRS_ALIGN_ANY);

        m_wndSystemLog.DockControlBar( AFX_IDW_DOCKBAR_BOTTOM, 2 );   

        ....

    }

}

.....

class CSystemLogView : public CWnd

{

     CRichEditCtrl m_reEdit;

     .....

}

SystemLog Wnd is displaying Log in CRichEdit. 

After several hour, no respond my app. no display UI. CPU usage 100%.

There is not enough information in your message to come to any conclusion about the problem. For example, the problem can be hidden in the rich edit control used in the log view implementation. If the rich edit control contains too much text lines, then adding new text lines into it takes big time.
