  Can anybody give me some idea about the following memory leak?
  I turned on memory leak detection in my VC++ MFC project.  The Data "SPPA", "ROPA", "MDIA", "md", "MFIA", etc. are stored in a struct:
  
  struct XMLMappingFields
  {
      CString strLogFlow;
      CString strLogMD;
      CString strLogMudWT;
      CString strLogROP;
      CString strLogSPP;
  };
  
  class CMyDoc : public CDocument
  {
  protected: // create from serialization only
      CMyDoc();
      DECLARE_DYNCREATE(CMyDoc)
  
  // Attributes
  public:
      BOOL m_bSkipDPa;
  
      long m_nJobID;
      CString m_strJobName;
  .....
      XMLMappingFields xmf;
   .....
  }
  
  However, when the program exit, in the VS debug window, it shows memory leak (See the end of my post for the output). Actually there is a memory leak in my program, but I cannot find it. I checked all new and delete pairs, I'm sure there is no missed delete. I used some COM object and MS XML toolkit objects in my application. the above XMLMappingFields struct is also used in the MS XML objects, is that the possible reason for the leak? Please give me some ideas! Thanks a lot!
  
  My Debug Window Output:
  ...............
  The thread 0x210 has exited with code 0 (0x0).
  Detected memory leaks!
