Bool PlaySound(LPCTSTR pszSound,//播放声音文件地址，NULL表示停止，想要只写文件名.wav就把wav和cpp放一起
HMODULE hmod,//声音文件的句柄
DWORD fdwSound);//控制声音播放
需要连接winmm.lib
方法是
#pragma comment(lib,“winmm.lib”)
或者：
项目-属性-链接器-输入-附加依赖项-编辑
fdwSound 如下：
#define SND_SYNC 0x0000 /* play synchronously (default) / 同步

#define SND_LOOP 0x0008 / loop the sound until next sndPlaySound /
#define SND_NOSTOP 0x0010 / don’t stop any currently playing sound */
#define SND_NOWAIT 0x00002000L /* don’t wait if the driver is busy /

#define SND_FILENAME 0x00020000L / name is file name / 文件读取声音
#define SND_RESOURCE 0x00040004L / name is resource name or atom /
#if (WINVER >= 0x0400)
