论文题目基于VC的MP3播放器设计与实现姓名学院学院专业计算机科学与技术指导教师讲师备注年月日基于VC的MP3播放器设计与实现作者姓名：指导教师：讲师单位名称：计算机科学与技术系专业名称：计算机科学与技术学校年月Design and Implementation of Mp3 PlayerBased on VCbySupervisor: Lecturer毕业设计（论文）任务书基于VC的MP3播放器设计与实现摘要本MP3播放器应用程序是一个基于Visual C++ 6.0 开发的一个多媒体软件，是建立在MCI（媒体控制接口）控制之上的软件。

该软件开发研究的目的主要是为了给人们娱乐和消遣用的；该软件实现的方法是通过调用MCI控制接口的相关函数，获取系统的控制信息，利用系统信息对MP3播放器的每一个动作进行控制。

现在为止，该软件到可以实现的功能是：该软件可以添加和播放多种音频文件格式，可以添加单个音频文件，也可以同时添加多个音频文件；对音频文件的操作有：播放音频文件、暂停、停止，可以选择播放下一首歌或前一首歌；可以对已经添加进入播放列表的音频文件进行删除或者添加新的音频文件；可以调节系统的音量的大小；该软件还可以显示当前播放的进度；可以隐藏或展开播放列表；本软件可以进行系统托管，隐藏主界面后，在任务栏创建托管图标；单击托管图标后可以重新弹出控制界面，并取消托管图标。

在系统托管或自动播放的情况下，该软件在播放完一首歌后可以自动跳转到下一首歌，并播放此音频文件。

关键词：媒体控制接口，多媒体，系统托管，控件，音频文件Design and Implementation of Mp3 PlayerBased on VCAbstractThe MP3 Player application programme is software that developed based on Visual C++ 6.0, and also is software that built on the control of MCI. The purpose of developing this software is for the entertainment and recreation of people. The way this software realized is transfer the correlation functions of MCI, and obtain the information of system control, using this information to control each movement of the MP3 Player.So far, the functions that software can realize are: The software can open and play different formats of audio-files,You can add the audio-file one by one or add many audio-files once; play the audio-files; pause; stop; play the following audio-file, and play the preceding audio-file. You can also delete the audio-files that the play list already have or add the new audio-file that the play-list does not exist. You can accommodate the volume of the system. The can show the progress that the current audio-file played. And can hide or outspread the play list. The software can trustee by the system, and will create a icon on the taskbar. When click the icon the interface will show again. While the current audio-file is playing over, it will jump to the next audio-file and play automatically.Key words: MCI，Media，System-Trustee，Controls，Audio-files目录毕业设计（论文）任务书 (I)摘要 (II)ABSTRACT.........................................................................................

Windows Media Player控件研究我的那个定时提醒程序中要用到它，初步使用问题已解决。

基本使用步骤如下：一、往控件箱中添加此控件：wmp.dll二、往窗体上拖控件三、wmp.URL=XXXX;wmp.play()即可。

平常应用就这三步就OK了。

但是，我想写个播放器的话，就遇到了一些问题。

在dotnet中使用非基于dotnet的控件，需要做一些额外的事，不过这些事vs 已经帮我们做好了，当我们拖了此控件进窗体时，vs会自动调用AxImp.exe，用它根据原有的dll或ocx生成一个用AxHost类包装的新的一组程序集(更为精确的描述见msdn)，于是根据WMPLib.dll生成两个文件：AxInterop.WMPLib.dll、Interop.WMPLib.dll。

这两个文件中包含了转化后的类。

包装后的控件继承自System.Windows.Forms.AxHost。

这是第一个问题，控件怎么使用呢？如果是拖控件，很简单，无论如何都能有效的使用。

但是，如果手工new创建控件的实例呢？那就不一定了。

我做过种种实验，获得如下的结论：在非可视化类中无法创建有UI的控件的实例，或者是在没有把实例加入到一个可视化的容器中时。

我实验了下面的代码：AxWMPLib.AxWindowsMediaPlayer wmp=new AxWMPLib.AxWindowsMediaPlayer();this.Controls.Add(wmp);wmp.URL="约定.mp3";wmp.Ctlcontrols.play();这几行代码不一定能运行。

发现，如果这几行代码写在窗体的构造函数中，哪怕show出来都不能运行，只有写在Load或Load之后的事件中，并且把窗体show出来才有运行，否则会抛出一个错误：引发类型为“System.Windows.Forms.AxHost+InvalidActiveXStateException”的异常。

控制台C语言编写音乐播放器主要功能音乐播放器是一种可以播放音乐文件的应用程序，具有多种功能来帮助用户管理和播放音乐。

下面是控制台C语言编写音乐播放器的主要功能：1.音乐：用户可以通过输入歌曲名或艺术家来他们想要播放的音乐。

功能也可以根据关键词进行过滤和排序。

2.音乐播放：一旦用户找到他们想要听的歌曲，他们可以选择播放它。

音乐播放器应该能够打开并解码音乐文件，然后通过音频设备播放音乐。

4.歌曲信息显示：在播放音乐的同时，音乐播放器应该显示歌曲的相关信息，如歌曲名、艺术家、专辑名、歌词等。

这些信息可以从音乐文件的元数据中获取。

5.音乐控制：音乐播放器应该具有基本的音乐控制功能，如播放、暂停、停止、上一首、下一首等。

用户可以通过命令来控制音乐的播放状态。

6.音量控制：用户可以通过增加或减少音量来调整音乐的音量。

音乐播放器应该能够调整音频设备的输出音量。

7.重复和随机播放：用户可以选择歌曲的播放模式，如顺序播放、循环播放、随机播放等。

音乐播放器应该能够根据用户的选择来调整播放模式。

9.用户界面：音乐播放器应该有一个简洁而直观的用户界面，允许用户轻松地浏览、和管理自己的音乐。

用户界面可以使用控制台界面或基于文本的界面。

10.错误处理：音乐播放器应该能够处理各种错误情况，如无效的输入、文件不存在、解码错误等。

它应该能够向用户显示有关错误的信息，并采取适当的措施来避免应用程序崩溃。

11.文件格式支持：音乐播放器应该支持多种常见的音乐文件格式，如MP3、WAV、FLAC等。

它应该能够根据文件格式选择合适的解码器。

12.常规设置：音乐播放器应该具有一些常规设置，如默认音量、默认播放模式、快捷键等。

用户可以根据自己的需求来调整这些设置。

以上是控制台C语言编写音乐播放器的主要功能。

根据以上功能，你可以开始设计和编写一个简单的音乐播放器应用程序。

当然，你可以根据个人需求和编程能力来扩展和优化这些功能。

一、软件说明：功能说明：一个简易小巧的MP3播放器，可以播放已经下载好的MP3格式的音乐。

解决什么样的实际问题：市场上的音乐播放器大都占用资源比较大，而且需要联网，即使播放本地音乐，也会占用较多的网速，而这款播放器解决了这些问题。

（虽然还是有很多缺陷，但用起来还是比较方便的。

）性能说明：可以播放单首或多首歌曲，可以保存或清空当前播放列表，支持列表循环，顺序播放，单曲循环。

（但目前只支持MP3格式。

）程序类型说明：这个播放器是winform应用程序。

二、软件设计软件整体结构图及模块划分：软件整体结构图：控制模块：歌曲列表显示区：在VS的“解决方案资源管理器”中的文件说明：整个项目的文件如下：其中，Properties中所包含的的文件有：这里包含的是定义程序集属性的文件，用来设定生成的有关程序集的常规信息dll文件的一些参数。

引用中包含的文件有：这里包含的是这个项目所用的的一些类库信息。

Form1.cs中包含有：这些是窗体的设计信息，而Program.cs是整个源程序的入口。

各模块对应的主要对象或方法：控制模块中主要用到的是axWindowsmediaPlayer控件以及MenuStrip控件。

其中Windows media Player 控件用到的方法属性主要有：axWindowsMediaPlayer1.BeginInit(); //初始化axWindowsMediaPlayer1.settings.autoStart; //自动播放axWindowsMediaPlayer1.settings.setMode("shuffle", false); //顺序播放axWindowsMediaPlayer1.settings.enableErrorDialogs;axWindowsMediaPlayer1.settings.balance;axWindowsMediaPlayer1.settings.mute;axWindowsMediaPlayer1.settings.volume;MenuStrip控件用到的方法事件有：privatevoid打开文件ToolStripMenuItem1_Click(object sender, EventArgs e);privatevoid添加歌曲ToolStripMenuItem_Click(object sender, EventArgs e);privatevoid添加文件夹ToolStripMenuItem_Click(object sender, EventArgs e);privatevoid退出ToolStripMenuItem_Click(object sender, EventArgs e); privatevoid清空列表ToolStripMenuItem1_Click(object sender, EventArgs e);privatevoid顺序播放ToolStripMenuItem_Click(object sender, EventArgs e);privatevoid单曲循环ToolStripMenuItem_Click(object sender, EventArgs e);privatevoid随机播放ToolStripMenuItem_Click(object sender, EventArgs e);数据库设计或数据文件说明：由于播放器使用数据量较小，故采用TXT保存歌曲文件列表。

Mp3 音乐播放器设计文档一、需求：名称：mp3音乐播放器目的：随时随地播放音乐、动画，查看文本文件输入：一个电源开关，一个确定按钮，上、下按钮，USB接口输出：液晶显示屏，耳机功能：可以从PC上下载各种电脑文件，具有移动存储的功能；能够识别并播放音乐文件，同步显示歌词，可以调节音效；显示.txt文本文件；性能：按钮刚按下即可刷新屏幕，所有操作在0.5秒内执行完毕生产成本：低于100元功耗：200mW物理尺寸和重量：体积不大于5cm*3cm*1cm；重量轻于100g二、规格说明1、概要规格说明系统的功能至少包括：接收从PC上下载的各类电脑文件并长久保存；执行用户选择的操作；列举所有音频文件，根据用户的选择播放任何一个文件，如有歌词则显示歌词；列举所有文本文件，根据用户选择显示任何一个；用例图：加电后的MP3执行过程：操作系统加载完成后，处于监听状态，在用户选择完需要完成的动作后，由操作系统调用相关对象的方法来实现其功能。

2、详细规格说明：所有的类及其成员变量、方法都归在类图之中Translate类：将数据转化成可以在LCD屏幕上显示的格式；Panel类：管理在屏幕上显示的各个选项，可以高亮表示选择，需要保存所有显示的item；FileSystem类：管理mp3中的所有可以识别的文件，可以读取、添加和删除文件；File类：抽象类，各个文件类型必须继承该类；Music类：表示音频文件类型，可以控制音频文件的播放、暂停、停止；TextFile类：表示文本文件类型，可以显示文本文件；Lyric类表示与音乐相关的歌词文件；Voice类：管理音乐的声音大小、播放模式（如摇滚、古典、流行等）ChangeSignal类：将音频文件转变成模拟信号，传输给耳机等外设。

当用户指定执行某种功能的时候，由操作系统来调用各个类的相关方法。

以下为某次用户要求播放某个音乐文件的顺序图：系统从FileSystem对象中获取文件，在Panel对象中显示出来，用户选择需要播放的音乐文件后，由Music对象播放；同时可以可以通过Voice对象调节音量；在播放结束后,Panel对象更新要显示的内容；每次更新后，都要由TranslateToLCD对象将其送到屏幕显示。
