MFC音乐播放器傻瓜教程

1、 代码下载地址1、建立工程21、建立一个MFC工程，命名为Tao_Music32、选择为基本对话框33、包含Windows Sockts44、使用静态链接库方便一会直接生成的exe文件单独可以发布52、 搭建界面51、 拖入控件：52、 控件拖入并摆好63、 控件属性设置：73、 写代码实现功能151、变量绑定：152、加入图片资源163、新建mp3类：174、修改Tao_MusicDlg.h205、修改Tao_Music.cpp216、功能实现：327、加一个TImer消息使时间跑起来！398、给音量控制滑块加消息，使音量控制实现42编译运行完工！431、建立工程1、建立一个MFC工程，命名

2、为Tao_Music2、选择为基本对话框3、包含Windows Sockts因为要用网络功能4、使用静态链接库方便一会直接生成的exe文件单独可以发布2、 搭建界面1、 拖入控件：拖入7个用于播放控制的button，一个picture控件，一个控制音量的滑块。一个Group Box用于盛放搜索功能各个控件及Group Box中2个静态文本，2个可编辑文本，一个搜索按钮。最下面的是一个List Control用于显示歌曲的。最终效果如下：2、 控件拖入并摆好3、 控件属性设置：选中Button1右键选择属性，弹出：将其改为：相同的道理将音乐控制的7个按钮和搜索按钮的Styles和Extended

3、 Styles都设置成相同的风格。Button2-8的General属性依次为：【注意大小写】相应的这里picture控件的属性为：音量滑块的属性为：Group Box的属性为：2个静态文本的属性只要改General就行啦：2个文本编辑框也只要改General就行：最后是list control控件的属性：好啦，最终的效果就是这样的：前面这么啰嗦大家千万别弄错啦！接下来就是写代码啦！3、 写代码实现功能1、变量绑定：查看->建立类向导->Member Variables将其设置为：【双击对应蓝条即出现设置对话框】最后别忘点确定！2、加入图片资源【首先用格式工厂转换出32X32的24

4、张bmp图片，放入工程文件的res文件中->进入Resource界面->右键Tao_Music resources->insert->弹出的对话框点击导入然后将你的24张bmp图片一个一个导入，注意这里最多每次导入8个，要分批导入！导入后的ID为IDB_BITMAP1-IDB_BITMAP24】3、新建mp3类：【插入->新建类】/mp3.h/音乐播放控制类#include "mmsystem.h"/必须同时引入#pragma comment(lib,"Winmm.lib")class mp3 public:mp3();vi

5、rtual mp3(); HWND m_hWnd;/3个变量DWORD DeviceID; MCI_OPEN_PARMS mciopenparms; void Load(HWND hwnd,CString Strfilepath);DWORD getinformation(DWORD item);void Play();void Pause();void resum();void Stop();DWORD Setvolumn(DWORD vol);/mp3.cpp#include "StdAfx.h"#include "mp3.h"#include &q

13、义歌词结构体int Time;TCHAR Lyric256;LRC_INFO;LRC_INFO LrcInfo500;5、修改Tao_Music.cppl 在include下面再引入下面几个文件和库：#include "mp3.h"#include "mmsystem.h"#include "digitalv.h"#include <afxinet.h>#include <shlwapi.h>#pragma comment(lib,"Winmm.lib")#pragma comment(li

14、b,"wininet.lib") #pragma comment(lib, "shlwapi.lib")l 紧接着在全局声明一个mp3型的全局变量：mp3 Mp3;l 转到OnInitDialog()函数处在return 前加入如下代码：/ TODO: Add extra initialization hereSetWindowText("MP3播放器");/标题m_slider.SetRange(0,1000); /移动范围m_slider.SetPos(500);/滑块指针的初始位置GetDlgItem(IDC_open)->
