ATL & ANSI字符串函数

        ATL创建组件工程中，我用了strupr函数，在Debug版中一切正常,但在Release版中出现链接错误:  
  LIBCMT.lib(crt0.obj)   :   error   LNK2001:   unresolved   external   symbol   _main  
  ReleaseMinDependency/ATL1.dll   :   fatal   error   LNK1120:   1   unresolved   externals  
        这是为什么，怎样解决?请高手指教 问题点数：20、回复次数：3Top

Project->Setting->C/C++   的Category中选择Preprocessor的Preprocessor   definitions:中去掉_ATL_MIN_CRT_。Top

Note   for   Release   builds   only       When   the   ATL   COM   AppWizard   generates   the   default   project,   it   defines   the   macro   _ATL_MIN_CRT.   This   macro   is   defined   so   that   you   don't   bring   the   C   Run-Time   Library   into   your   code   if   you   don't   need   it.   The   polygon   control   needs   the   C   Run-Time   Library   start-up   code   to   initialize   the   floating-point   functions.   Therefore,   you   need   to   remove   the   _ATL_MIN_CRT   macro   if   you   want   to   build   a   Release   version.   To   remove   the   macro,   click   Settings   on   the   Project   menu.   In   the   Settings   For:   drop-down   list,   choose   Multiple   Configurations.   In   the   Select   project   configuration(s)   to   modify   dialog   box   that   appears,   click   the   check   boxes   for   all   four   Release   versions,   then   click   OK.   On   the   C/C++   tab,   choose   the   General   category,   then   remove   _ATL_MIN_CRT   from   the   Preprocessor   definitions   edit   box.
