建错了工程，你一定是建了一个控制台工程了。
将project-->settings-->link的project options里的/subsystem:console 后将其删掉或者改成/subsystem:windows。

[写不动代码的人]

工程类型不对，创建的是win32 console工程，使用的确是WinMain入口函数

[gameslq]

建的工程类型不对，应该是win32 application 而当前的是 win32 console application
解决办法 重建新的工程类型或者
Project] --> [Settings] --> 选择"Link"属性页,
在Project Options中将/subsystem:console改成/subsystem:windows

谢谢各位大虾指导，已经成功运行了，但是为什么没有声音呢？

PlaySound(TEXT ("hellowin.wav"), NULL, SND_FILENAME | SND_ASYNC) ;
先改用绝对路径试试
不行再GetLastError错误码
