求助, 一段VC++代码, 仿照孙鑫那个视频写的, 为什么出错呢?帮忙找找 ,谢谢

错误信息: LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main Debug/C.exe : fatal error LNK1120: 1 unresolved externals 执行 link.exe 时出错.

答案：就像楼下说的，你得创建win32窗体工程，而不是win32命令行工程。命令行是与传统C/C++兼容的，应用的入口点为main（如果你深入了解的话，会看到在CRT在外面又包了一层，新手可以忽略不管），而win32窗口应用入口点为WinMain函数。WinMain函数在命令行（cmd）里调用是立即返回的，这个与main不一样。在创建win32命令行工程时，有时看到入口函数（也就是主函数）被命名为_tmain，这个是一样的道理。你只需要知道，操作系统在调用你的程序的时候，它会调用你的main/_tmain/WinMain函数就行了

其他：创建win32工程
