用mciSendString（）实现音乐播放
这里借助了建立对话程序的插件，在VC中建一个简单的对话框工程，拖入一个按钮ID取"IDC_OK"。文件结构如下：
MainDlg.h:
#ifndef _MAIN_H
#define _MAIN_H
#include <windows.h>

BOOL Main_OnInitDialog(HWND hwnd, HWND hwndFocus, LPARAM lParam);
void Main_OnCommand(HWND hwnd, int id, HWND hwndCtl, UINT codeNotify);
void Main_OnClose(HWND hwnd);
#endif
Resource.h:
//{{NO_DEPENDENCIES}}
// Microsoft Developer Studio generated include file.
// Used by resource.rc
//
#define IDD_MAIN 101

// Next default values for new objects

#define _APS_NEXT_SYMED_VALUE 101
#endif
#endif

// or project specific include files that are used frequently, but
// are changed infrequently

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers
