各位大神看看这条代码，为什么组建老有错误。提示的错误为：Linking...
LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/MainDlg.exe : fatal error LNK1120: 1 unresolved externals

这是控制台程式和窗口程式的区别

error LNK2001: unresolved external symbol _main=====>这个信息明显就是你想编写控制台程式

但是编译器却无法找到main函数

那要怎么改呢

vc6 吗   具体得看你是啥ide

id?那是什么
