从VC6迁移到VS2005 - ATL

1.      vc8以上版本推荐使用结尾为”_s”的改进函数(s-safe)

比如原函数 -> 安全函数

       fopen() ->fopen_s(),

       localtime()-> localtime_s()

       _itoa() ->_itoa_s()

      strcpy() ->strcpy_s()

      strncat() ->strncat_s()

2.      “project property” ->“Configuration Properties” -> “Linker”下的选项“Per-userRedirection” 为 “Yes”；

          这样vc9才能通过编译。vc8无此选项。

3.      “project property” ->“Configuration Properties” -> “Custom Build Step” 下的选项“Description” 为“Performing Custom Build Step”；

         清除其它选项的值。vc8默认已经清除。

4.      Vista 下COM的注册必须为administrator模式

         单击”命令提示符”右键”以管理员身份运行”即进入administrator模式
