生命是过客，人在旅途。奶奶是信基督教的，没啥文化，却养育了四子二女，还带过九个孙辈。老人家对生命的看法就是“人都是客人，迟早要回去的。”就以《人在旅途》来纪念她。

 [微软技术开发]Important notes before implement Interface of COM using ATL |
人在旅途 发表于 2006/1/22 8:26:43 |
BEGIN_COM_MAP(CThisObject) COM_INTERFACE_ENTRY(IUnknown) COM_INTERFACE_ENTRY_CHAIN(COtherObject)END_COM_MAP( )Caution As of version 3.0, ATL uses the compiler keyword __uuidof( class ) to obtain the corresponding IID for a given class. Because of changes in the COM_INTERFACE_ENTRY macros effective in version 3.0, now you simply include the header for the interface to use, instead of also linking to a library that defines the matching IIDs for that interface. This change can cause problems if the header was previously generated by an older version of MIDL, or if it was hand-coded and not marked appropriately. If the declaration for the interface in the header has not been marked with an associated __declspec( uuid ), then any attempt to use the __uuidof keyword for that interface will fail. You can revert to the older (ATL 2.x) COM_INTERFACE_ENTRY macros by defining _ATL_NO_UUIDOF in your build settings to work around any problems with this new behavior.
