Creating library ReleaseMinSize/LearnBetterPPT.lib and object ReleaseMinSize/LearnBetterPPT.exp

        用Win32  Realese Minsize 或 Win32   Realese   Mindependence方式编译用VC6.0编写的ATL COM组件时出现如下错误:

        Creating library ReleaseMinSize/LearnBetterPPT.lib and object ReleaseMinSize/LearnBetterPPT.exp
        LIBCMT.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
        ReleaseMinSize/LearnBetterPPT.dll : fatal error LNK1120: 1 unresolved externals
        Error executing link.exe. 

        解决办法：在Project------> Setting-----> C/C++----> Preprocessor definitions 下删除：_ATL_MIN_CRT即可。
