一、添加媒体操作变量：

CWMPPlayer40 mPlayer4;//插件变量 ?CWMPSettings mSet;?//setting变量 ?CWMPControls mmCtrl;// Controls变量 ?CWMPPlaylist mlist; //list变量

CWMPMedia mMedia;//媒体文件变量 ?

二、OnInitDialog()

mPlayer4.put_URL(_T("F:\\CloudMusic\\刘珂矣 - 如是.mp3"));

mmCtrl = static_cast(mPlayer4.get_controls());//成员变量初始化 ?mSet? = static_cast(mPlayer4.get_settings()); ?mlist = static_cast(mPlayer4.get_currentPlaylist()); ? ?mPlayer4.put_currentPlaylist(mlist);?//不必须，设置播放列表 ?mSet.put_autoStart(TRUE);//自动播放 ?mSet.setMode(_T("loop"),TRUE);//单曲循环

MFC入门-MCI简单音乐播放器实现

实现功能：

1)????????播放

2)????????暂停/恢复

3)????????停止

4)????????音量调节

?

实现步骤：

1创建工程

打开VS2010，新建-》文件-》新建项目：

点击确认之后：

点击下一步：

选择“基于对话框”，点击“下一步”：

点击“下一步”：

点击“下一步”：

默认选项，点击“完成”

默认生成的界面。

2界面制作

界面制作如下：

音乐播放界面

这里说明每个控件对应的Id：

文件名称后面的编辑框：IDC_filename

浏览按钮：IDC_filechoice

播放按钮：IDC_play

暂停按钮：IDC_pause

停止按钮：IDC_stop

音量调节里面的编辑框：IDC_volume

音量滑动条：IDC_SLIDER1

版本说明按钮：IDC_about

退出软件按钮：IDC_exitbtn

软件说明界面：

3逻辑功能实现

3.1软件说明：

void Cmfc_music_playerDlg::OnBnClickedabout()

{

// TODO: 在此添加控件通知处理程序代码

CAboutDlg dlg;

dlg.DoModal(); //弹出软件说明

}

3.2退出软件：

void Cmfc_music_playerDlg::OnBnClickedexitbt()

{

// TODO: 在此添加控件通知处理程序代码

CDialog::OnCancel(); //退出

}

3.3加载

添加头文件和库：

#include

#include

#pragma comment(lib, "Winmm.lib")

//定义三个全局变量

HWND m_hWnd;

DWORD DeviceId;

MCI_OPEN_PARMS mciopenparms;

//加载

void Load(HWND hWnd, CString strFilepath)

{

m_hWnd = hWnd;

mciSendCommand(DeviceId, MCI_CLOSE, 0, 0); //在加载文件前先清空上一次播放的设备

mciopenparms.lpstrElementName = strFilepath; //将音乐文件路径传给设备

DWORD dwReturn;

if (dwReturn = mciSendCommand(NULL, MCI_OPEN, MCI_OPEN_ELEMENT | MCI_WAIT, (DWORD)(LPVOID)&mciopenparms))

{

//如果打开玩家失败,将出错信息储存在buffer,并显示出错警告

char buffer[256];

mciGetErrorString(dwReturn, buffer, 256); //获取错误码对应的错误信息

MessageBox(hWnd, buffer, "出错警告！", MB_ICONHAND | MB_ICONERROR | MB_ICONSTOP); //弹出错误信息提示对话框

}

DeviceId = mciopenparms.wDeviceID;

//打开文件成功就关联文件到设备

}

3.4播放

//播放

void play()

{

MCI_PLAY_PARMS mciplayparms;

mciplayparms.dwCallback = (DWORD)m_hWnd;

mciplayparms.dwFrom = 0; //每次播放都是从0开始播放

mciSendCommand(DeviceId, MCI_PLAY, MCI_FROM | MCI_NOTIFY, (DWORD)(LPVOID)&mciplayparms);

}

3.5暂停

void pause()

{

mciSendCommand(DeviceId, MCI_PAUSE, 0, 0);

}

3.6恢复

void resume()

{

mciSendCommand(DeviceId, MCI_RESUME, 0, 0);

}

3.7停止

void stop()

{

mciSendCommand(DeviceId, MCI_STOP, 0, 0);

mciSendCommand(DeviceId, MCI_CLOSE, 0, 0);

//当点击停止按钮时,将所有的信息都清除掉

}

3.8音量调节

//设置音量

DWORD setVolume(DWORD vol)

{

MCI_DGV_SETAUDIO_PARMS setvolume; //设置音量的参数结构体

setvolume.dwCallback = NULL; //

setvolume.dwItem = MCI_DGV_SETAUDIO_VOLUME; //动作是设置音量

setvolume.dwValue = vol; //音量值是vol

mciSendCommand(DeviceId, MCI_SETAUDIO, MCI_DGV_SETAUDIO_ITEM | MCI_DGV_SETAUDIO_VALUE, (DWORD)(LPVOID)&setvolume);

return 0;

}

4界面事件关联

4.1文件选择

void Cmfc_music_playerDlg::OnBnClickedfilechoice()

{

// TODO: 在此添加控件通知处理程序代码

char szFileFilter[] = "mp3文件(*.mp3)|*.mp3|"

"wma文件(*.wma)|*.wma|"

"wav文件(*.wav)|*.wav|"

"所有文件(*.*)|*.*|";

CFileDialog dlg(true, NULL, NULL, OFN_HIDEREADONLY, szFileFilter);

if (dlg.DoModal() == IDOK)

{

CString strFilepath = dlg.GetPathName();

CString strFilename = dlg.GetFileName();

SetDlgItemText(IDC_filename, strFilename);

Load(this->m_hWnd, strFilepath);

}

GetDlgItem(IDC_play)->EnableWindow(true); //文件读取成功时所有按钮变成可选

GetDlgItem(IDC_pause)->EnableWindow(true);

GetDlgItem(IDC_stop)->EnableWindow(true);

}

4.2播放按钮

void Cmfc_music_playerDlg::OnBnClickedplay()

{

// TODO: 在此添加控件通知处理程序代码

play();

SetDlgItemText(IDC_pause, "暂停");

}

4.3暂停/恢复按钮

void Cmfc_music_playerDlg::OnBnClickedpause()

{

// TODO: 在此添加控件通知处理程序代码

CString strTemp;

GetDlgItemText(IDC_pause, strTemp); //获取按钮的状态

if (strTemp.Compare("暂停") == 0)

{

pause();

SetDlgItemText(IDC_pause, "恢复");

}

if (strTemp.Compare("恢复") == 0)

{

resume();

SetDlgItemText(IDC_pause, "暂停");

}

}

4.4停止按钮

void Cmfc_music_playerDlg::OnBnClickedstop()

{

// TODO: 在此添加控件通知处理程序代码

stop();

SetDlgItemText(IDC_pause, "暂停");

GetDlgItem(IDC_play)->EnableWindow(false); //当按下stop的时候,播放和暂停不可选

GetDlgItem(IDC_pause)->EnableWindow(false);

}
