各位大虾帮忙看一下，如何改调用WAV的函数
代码如下// mytextDlg.cpp : implementation file

#include <Windows.h>

我想把switch(bt){
case 49: Beep(987 ,500);break;
case 50: Beep(1108 ,500);break;
case 51: Beep(1244 ,500);break;
case 52: Beep(1318 ,500);break;
case 53: Beep(1479 ,500);break;
case 54: Beep(1660 ,500);break;
case 55: Beep(1863 ,500);
中的BEEP改为播放一个c:\新建文件夹的wav声音，是不是把beep改为直接改为 PlaySound("c:\新建文件夹\n.wav", NULL, SND_FILENAME | SND_ASYNC); 就可以了？就像这样
case 49: PlaySound("c:\新建文件夹\1.wav", NULL, SND_FILENAME | SND_ASYNC);break;
case 50: PlaySound("c:\新建文件夹\2.wav", NULL, SND_FILENAME | SND_ASYNC);break;
case 51: PlaySound("c:\新建文件夹\3.wav", NULL, SND_FILENAME | SND_ASYNC);break;
case 52: PlaySound("c:\新建文件夹\4.wav", NULL, SND_FILENAME | SND_ASYNC);break;
case 53: PlaySound("c:\新建文件夹\5.wav", NULL, SND_FILENAME | SND_ASYNC);break;
case 54: PlaySound("c:\新建文件夹\6.wav", NULL, SND_FILENAME | SND_ASYNC);break;
case 55: PlaySound("c:\新建文件夹\7.wav", NULL, SND_FILENAME | SND_ASYNC);
？恳请大家指点
