用mciSendString( )实现音乐播放，可以播放wav,mp3,wma,等音频文件。

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 WINAPI Main_Proc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam);

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

#define IDC_OK 1000

 

// Next default values for new objects

//

#ifdef APSTUDIO_INVOKED

#ifndef APSTUDIO_READONLY_SYMBOLS

#define _APS_NEXT_RESOURCE_VALUE 103

#define _APS_NEXT_COMMAND_VALUE 40001

#define _APS_NEXT_CONTROL_VALUE 1004

#define _APS_NEXT_SYMED_VALUE 101

#endif

#endif

 

StdAfx.h:

// stdafx.h : include file for standard system include files,

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

// are changed infrequently

//

 

#if !defined(AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_)

#define AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_

 

#if _MSC_VER > 1000

#pragma once

#endif // _MSC_VER > 1000

 

#define WIN32_LEAN_AND_MEAN        // Exclude rarely-used stuff from Windows headers

 

#include <windows.h>

 

 

// TODO: reference additional headers your program requires here

 

//{{AFX_INSERT_LOCATION}}

// Microsoft Visual C++ will insert additional declarations immediately before the previous line.

 

#endif // !defined(AFX_STDAFX_H__A9DB83DB_A9FD_11D0_BFD1_444553540000__INCLUDED_)

 

StdAfx.cpp:

// stdafx.cpp : source file that includes just the standard includes

//    音乐播放器.pch will be the pre-compiled header

//    stdafx.obj will contain the pre-compiled type information

 

#include "stdafx.h"

 

// TODO: reference any additional headers you need in STDAFX.H

// and not in this file

 

MainDlg.cpp:

#include "stdafx.h"

#include <windows.h>

#include <windowsx.h>

//#include <stdio.h>

#include <commdlg.h>

#include <mmsystem.h>

//记得还要在"工程"->"设置"->"连接"->"对象/库模块"中添加"winmm.lib"

#include "resource.h"

#include "MainDlg.h"
