一些标识缺少定义，是不是少引用了头文件。
查找下哪个文件里边有它们的定义吧，例如：SM_MOUSEWHEELPRESENT　这个。

[wltg2001]

在CPP文件前面加#define WINVER 0x0500试试

[wltg2001]

刚才试了一下,直接加#define WINVER 0x500不行,不过这个错误的原因是还是因为WINVER 值太小了,你可以打开windows.h,将里面宏WINVER的值改成0x500试试

[寻找科技]

谢谢 wltg2001(红猪) 的解答,问题解决了.
前面几个错误是加了

#define WINVER 0x500

就解决了,倒数2.3,是我输错了,最后一个是不知不觉就解决了,也不知道是什么原因.
