IDiaEnumLineNumbers* GetLineNumbersByAddr(IDiaSymbol *pFunc,  
                                          IDiaSession *pSession)  
{  
    IDiaEnumLineNumbers* pEnum = NULL;  
    DWORD                seg;  
    DWORD                offset;  
    ULONGLONG            length;  
  
    if (pFunc->get_addressSection ( &seg ) == S_OK &&  
        pFunc->get_addressOffset ( &offset ) == S_OK)  
    {  
        pFunc->get_length ( &length );  
        pSession->findLinesByAddr( seg, offset, static_cast<DWORD>( length ), &pEnum );
